The Tesla Model S is a full-sized all-electric five-door, luxury liftback, produced by Tesla, Inc., and introduced on 22 June 2012. It scored a perfect 5.0 NHTSA automobile safety rating. The EPA official range for the 2017 Model S 100D, which is equipped with a 100 kWh (360 MJ) battery pack, is 341 miles (550 km), higher than any other electric car. The EPA rated the 2017 90D Model S's energy consumption at 200.9 watt-hours per kilometer (32.33 kWh/100 mi or 20.09 kWh/100 km) for a combined fuel economy of 104 miles per gallon gasoline equivalent (2.26 L/100 km or 125 mpg_-imp). In 2016, Tesla updated the design of the Model S to closely match that of the Model X. As of October 2017, the following versions are available: 75D, 100D and P100D.

The Model S became the first electric car to top the monthly new car sales ranking in any country, twice leading in Norway, in September and December 2013 and also in Denmark in December 2015. Global Model S sales passed the 150,000 unit milestone in November 2016, with the U.S. as the leading market with 57% of global sales. Other leading country markets are Norway, China, Hong Kong, the Netherlands, Canada, Denmark, Germany, and Switzerland.

The Tesla Model S was the top selling plug-in electric car worldwide in 2015 and 2016, and by the end of 2016 was the second-most sold electric car in history after the Nissan Leaf.

The Tesla Model S was the 2013 World Green Car of the Year, 2013 Motor Trend Car of the Year, Automobile magazine's 2013 Car of the Year, Time Magazine Best 25 Inventions of the Year 2012 award and Consumer Reports top-scoring car in its road testing. In 2015, Car and Driver named the Model S the Car of the Century. After not recommending the Model S in 2015 due to poor reliability, one year later Consumer Reports added the car to its recommended list.

History

The Model S was styled by Franz von Holzhausen, who previously worked for Mazda North American Operations. The car was codenamed WhiteStar during research and preliminary development. It was officially announced in a press release on June 30, 2008. The prototype vehicle was displayed at a press conference on March 26, 2009. Exclusive premier of their Model S electric car was held at their Menlo Park store on April 8, 2009.

In February 2008 it was reported that Tesla, Inc. (then Tesla Motors) was planning to offer a range-extended version of its Model S. This version would have included a gasoline engine to extend the driving range of the vehicle, but it was removed in later revisions. At the GoingGreen conference in September 2008 Tesla's CEO, Elon Musk, announced that Tesla was developing only electric cars.

Construction of an assembly factory in Albuquerque, New Mexico (a central location for shipping) was supposed to begin in April 2007, but was cancelled. A factory to be built in San Jose, California was also announced. In May 2010 Tesla announced it would produce the Model S at the former NUMMI assembly plant in Fremont, California, now known as the Tesla Factory. This third plan was implemented.

Tesla said in that after three years, Model S cars traveled over 1 billion miles (1.6 billion km), the first plug-in electric to reach that total. In 2014 the Volt total was 629 million all-electric miles (1 billion km) out of a total of 1 billion miles traveled, while Nissan said the Leaf had accumulated 625 million total miles. Tesla said 68% of Model S travel was in North America, 25% in Europe and 7% in Asia-Pacific. Global Model S sales passed the 100,000 units in 2015, and the 150,000 mark in November 2016.

In 2016, the "Electric GT World Series" was promoted in preparation for a 2017 racing season using the P85+ as a race car on certain traditional tracks. The first season is planned to have 20 cars in 10 teams.

In April 2016, Tesla made minor changes in the Model S. The front fascia has a similar design as the Model X, adding adaptive LED headlights. A HEPA cabin air filtration system was added. The standard charger increased 40 to 48 amps, speeding charging at higher-amperage outlets. Two ash wood interior options were added.

Production

Tesla manufactures the Model S at the 5.4 million square foot Tesla Factory in Fremont, California. For the European market, Tesla assembles and distributes from its European Distribution Center in Tilburg, the Netherlands. Cars are built and tested in Fremont, California. The battery pack, the electric motor and parts are disassembled and shipped separately to Tilburg, where the cars are reassembled. The center occupies a 203,000 sq ft (18,900 m²) industrial building that also serves as a workshop and spare parts warehouse. Tesla expects the Model S to "pay back" the energy that went into producing the car in fewer than 10,000 miles (16,000 km).

The first ten customers received their cars at the Fremont factory on June 22, 2012 at the official launch. Production grew from 15-20 cars completed/week in August 2012 to about 1,000 cars per week in 2015.

In October 2015, Tesla announced the company is negotiating with the Chinese government on producing its electric cars domestically. Local production has the potential to reduce the sales prices of Tesla models by a third. Elon Musk said production will remain in the U.S., but if there is sufficient local demand for the Model 3 in China, a factory could be built in the country as soon as a year after the launch of the new model. Production in Europe will also depend on the region's demand for the Model 3.

Design

The Model S exists in several versions, differing in energy capacity (battery size), power (motor size), and equipment. It is classified as a fullsize luxury car in the USA, or as a "Large Car" (120 cu ft or more) or "Luxury Sedan" by the EPA. The Euro Car Segment classification is S-segment (sports car), or "Oberklasse" (F-segment) in Germany.

Powertrain

The 2012 Tesla Model S Performance model has a three phase, four pole AC induction 416 hp (310 kW) and 443 ft·lb (600 N·m) rear-mounted electric motor with copper rotor. The base model uses a 362 hp (270 kW) and 325 ft·lb (440 N·m) motor.

The company claimed a drag coefficient of Cd=0.24, lower than any car when released. Independent measurement by Car And Driver in May 2014 bore out Tesla's claim by exactly confirming a drag coefficient of Cd=0.24.

The rear axle has a traditional open differential. Models with dual motors also have an open differential on the front axles as well. The front and rear axles have no mechanical linkage - with dual motors the power distribution among them is controlled electronically.

The Model S P90D has a top speed of 155 mph (250 km/h) and it accelerates from 0 to 60 miles per hour (0 to 97 km/h) in 2.8 seconds, despite the lower total motor power, in part due to the improved traction of the all-wheel drive powertrain. The Model S P85D, a dual motor all-wheel drive vehicle has a governed top speed of 155 mph (250 km/h) and it accelerates from 0 to 60 miles per hour (0 to 97 km/h) in 3.2 seconds (tested to 3.1 seconds), under "Insane Mode", with 1g of acceleration. New P85Ds have an optional "Ludicrous Mode" hardware package available with the 90 kWh battery upgrade (thus becoming a P90D) that improves the 0 to 60 miles per hour (0 to 97 km/h) acceleration to 2.8 seconds and 1.1g. Tesla initially reported the total output in the P85D as the arithmetic addition of the maximum power of the individual electric motors at 691 hp (515 kW) but later reported it as 463 hp (345 kW) because the two motors do not give their maximum power at the same time.

As of March 2017, the P100D variant holds the record for the fastest acceleration of any production vehicle with a NHRA rolling start to 60 mph in Motor Trend tests with 2.28 seconds (0 to 100 km/h in 2.36 seconds) in ludicrous mode, although other independent tests have placed it behind the Porsche 918 Spyder. Due to overheating issues, Tesla limits the amount of times that a driver is able to use ludicrous mode within a certain amount of time, as driving the car in that mode may shorten the battery's lifespan and can cause damage to the car. According to MotorTrend, selecting the "Yes, bring it on!" option for maximum acceleration "initiates a process of battery and motor conditioning, wherein the battery temperature is raised slightly and the motors are cooled using the air-conditioning system. It usually takes just a few minutes, longer in extreme ambient temperatures or after repeated runs. You should expect to wait a minimum of 10 minutes in between runs."

The powertrain provides regenerative braking power of more than 60 kW which reduces both energy consumption and improves brake lifetime. Owners reported many powertrain issues from 2012, improving significantly over the years. In July 2015, Tesla announced its goal to make the Model S powertrain last for one million miles. By 2017, in the Consumer Reports Car Reliability Survey, Tesla's position on the list had moved up four spots; the predicted reliability rating for Model S reached "above average" for the first time.

Dual-motor all-wheel-drive versions

On October 9, 2014, Tesla announced the introduction of All Wheel Drive (AWD) versions of the Model S's 60, 85, and P85 models, designated by a D at the end of the model number.

On April 8, 2015, Tesla introduced the Model S 70D as its new entry-level car, with all-wheel drive and an improved range of 240 miles (385 km)}; an 5 kWhe could be purchased with a software unlock. The 70D replaced the 60 and 60D in the Model S lineup, with the latter two models no longer being available for purchase. The P85 option was also dropped.

In the 85D, the rear drive unit is replaced by a smaller one to save cost and weight, while the second motor of similar size is added to the front wheels. This results in an AWD car with comparable power and acceleration to the RWD version. Additionally, Tesla said the 85D has a 2% (5-mile) range increase and 11% increase in top speed over the 85. In the P85D, the high-power rear drive unit is retained, while a new front drive motor boosts the total power by about 50%. This results in a significant increase in acceleration and top speed. Deliveries of the P85D started in December 2014, with the 85D models starting in February 2015, and the 70D models starting in April 2015.

On June 9, 2016, Tesla reintroduced the 60 and 60D, which has a 75 kWh battery, software locked to 60 kWh and there is an option to purchase an unlock for the 75 kWh capacity. The early 2016 refresh also offers the "Bioweapon Defense Mode" airfilter first offered on the Model X.

On August 23, 2016, Tesla introduced the Model S P100D with ludicrous mode as its new top-level car, with all-wheel drive and an improved EPA estimated range of 315 mi (507 km). This version of the Model S is notable for being the first electric vehicle to have a U.S. EPA estimated range greater than 300 miles (485 km) and for being the fastest accelerating vehicle currently in production, with a 0-60 mph (0-97 km/h) time of 2.5 seconds, when optioned with ludicrous mode.

On April 16, 2017, Tesla removed the model 60 and 60D options, since most customers pick the larger 75-kwh battery option. This made the Model S 75 the entry-level Model S.

Battery

In 2012, the EPA range for the 60 kWh battery pack model was 208 mi (335 km) and the 85 kWh battery was 265 miles (426 km). According to Musk, the Model S has a battery with twice the energy density of that on the Nissan Leaf, but the difference in range is more than double. This is also due to other factors such as drag coefficient, weight, motor efficiency and rolling resistance. Musk stated that driving at 65 mph (105 km/h), under normal conditions, gives a reasonable range of 250 miles (400 km).

The energy-saving sleep state powers off the display and other vehicle electronics, after the car goes to sleep. This increases the time it takes the touchscreen and instrument panel to become usable. This mode can decrease the loss of the car's range when not being used (2.3 mi, 3.7 km per day, as of 2013).

The 85 kWh battery pack weighs 1,200 lb (540 kg) and contains 7,104 lithium-ion battery cells in 16 modules wired in series (14 in the flat section and two stacked on the front). Each module contains 6 groups of 74 cells wired in parallel; the 6 groups are then wired in series within the module. As of June 2012, the battery pack used modified Panasonic cells with nickel-cobalt-aluminum cathodes. Each cell was of the 18650 form factor (i.e., an 18 mm diameter, 65 mm height cylinder), similar to the Panasonic NCR18650B cell that has an energy density of 265 Wh/kg. Analysts estimate battery cost to be around 21-22% of the car cost.

The battery is guaranteed for eight years or 125,000 miles (200,000 km in metric countries) for the base model with the 60 kWh battery pack. The 85 kWh battery pack is guaranteed for eight years and unlimited miles. A poll among drivers indicate that accumulated battery loss steadies around 5% after 30,000 miles (50,000 km), decreasing further about 1% per additional 30,000 miles. Unlike Nissan, Tesla does not specify a limit for battery loss, but some early battery packs have been replaced. A separate battery replacement guarantee takes effect after the eighth year for the 60 kWh and 85 kWh batteries. Lithium-ion batteries operate best at certain temperatures. The Model S motor, controller and battery temperatures are controlled by a liquid cooling/heating circuit. Waste heat from the motor heats the battery in cold conditions, and battery performance is reduced until a suitable battery temperature is reached.

In 2013, Tesla canceled a 40 kWh version of the car due to lack of demand, saying that only 4% of pre-orders were for the 40 kWh battery option. Customers who ordered this option instead received the 60 kWh pack, with charge software-limited to 40 kWh (139 miles, 224 km). It has the improved acceleration and top speed of the bigger pack and can be upgraded to use the full 60 kWh.

On April 8, 2015, Tesla discontinued the Model S 60, and replaced the base model with the Model S 70.

In 2015, Tesla introduced a 70 kWh battery to replace the existing 60 kWh batteries and base 60 kWh Model S vehicles, as the 60 was low margin and not sufficiently welcomed by customers. All 70 kWh cars can be had with rear-wheel drive or all wheel drive. The 60 was re-introduced in 2016 as a software-limited 75, upgradable to 75.

In July 2015, Tesla introduced its 70, 90, 90D and P90D variants along with a "ludicrous mode" for the performance model. The P90D combines a front axle power of 259 horsepower (193 kW) and rear axle power of 503 horsepower (375 kW) to a total of 762 horsepower (568 kW), for a 0-60 mph time of 2.8 sec. The acceleration of the P90D can reach 1.1g, described by Tesla as "faster than falling".

Tesla described its July 2015 introduction of the 90 kWh battery as a "range upgrade" of the 85 kWh battery and explained that the 6% energy increase was due to "improved cell chemistry" and the introduction of silicon into the cell's graphite anode. Tesla additionally announced its expectation of an annual improvement in battery capacity of about 5%. Tesla also explained that apart from the P90D the Model S has its main battery conductor protected by a fuse rated for 1,300 A and that this rating is somewhat conservative given the uncertainty of the exact conditions under which a fuse melts. To reduce this uncertainty Tesla has for the P90D introduced Inconel battery contactors and an electronically controlled pyro-activated fuse, which monitors the current at the millisecond level, cuts the power with "extreme precision and certainty" and has a rating of 1,500 A.

In February 2016, the 85 kWh battery option was discontinued in countries including the US, Australia and Canada.

In March 2016, media reported that a firmware version distributed for the Tesla Model S had support for a P100D variant that was yet to come. This battery is more complicated to make than the 90 version. The P100D was released in August 2016.

In April 2017, Tesla ceased offering the 60 kWh software limited battery option. The lowest capacity option became the 75 kWh, and at the same time Tesla significantly reduced the software upgrade options for facelifted 60 and 70 models to be upgraded over-the-air to 75 (and rebadged at their next visit to a Tesla service centre).

Practicality and livability

The Model S is notable for being designed solely with an electric powertrain in mind, unlike other vehicles where the manufacturer has simply swapped out or supplanted an internal combustion engine with an electric motor. As a result, the Model S is able to offer unique features such as a front trunk, 'frunk', in addition to a spacious rear trunk (with a total cargo volume of 31.56 cu ft (894 L)) and a greatly enlarged front crumple zone compared to the typical combustion engine powered vehicle.

To enhance livability, Tesla has developed a network of fast-charging 'Supercharger' stations that allow the driver to quickly and easily top-up the charge on their Model S. This Supercharger network has rapidly expanded in Europe, across the United States, and other countries where there is significant demand, and as of September 2016, the network has been established in most American states, thus making cross-country and long distance trips in an electric vehicle feasible and greatly alleviating fears of range anxiety.

Researchers from the University of California, Davis conducted a study to identify the factors influencing the decision to adopt high-end battery electric vehicles (BEV), such as the Tesla Model S, as these vehicles are remarkably different from mainstream BEVs. The 2016 study found that "environmental, performance, and technological motivations are reasons for adoption; the new technology brings a new segment of buyers into the market; and financial purchase incentives are not important in the consumer's decision to adopt a high-end BEV."

Specifications

Energy consumption

Under its five-cycle testing protocol, the United States Environmental Protection Agency (EPA) rated the 90 kWh Model S model with a combined fuel economy equivalent of 104 MPGe (2.26 L/100 km or 125 mpg_-imp), with an equivalent 102 mpg_-US (2.3 L/100 km; 122 mpg_-imp) in city driving and 107 mpg_-US (2.2 L/100 km; 129 mpg_-imp) on highways.

The following table shows the EPA's official ratings for fuel economy in miles per gallon gasoline equivalent (MPGe).

Battery placement

In contrast to most other battery electric vehicles including the Roadster, the battery pack of the Model S forms the floor of the vehicle between the axles, providing the vehicle with several advantages. Most notably, since the battery pack is the heaviest component of the vehicle, the Model S has a center of gravity height of only 18 inches (46 cm) (about the same as a Lotus Elise), helping it to achieve a lateral acceleration of 0.9g and good protection against rollover. Secondly, the absence of a heavy engine between the front or rear axle allows the bulk of the mass to be centralized between the axles, lowering rotational inertia allowing it to turn more quickly for its weight. Thirdly, the placement of the battery pack increases the rigidity of the passenger compartment, improving the passive safety of the vehicle. Fourth, placing the battery pack under the vehicle makes it possible to remove or replace the entire unit in 90 seconds, either for maintenance or for Tesla's Battery Swap service.

Charger

In all markets the charge port is located behind a door in the left taillight. During charging, the charge port pulses green. The frequency at which the charge port's light pulses slows down as the charge level approaches full. When charging is complete, the light stops pulsing and is solid green.

The Model S comes equipped with a different charger and connector in North American versus other markets, derived from differences in the local electric grid systems.

North America

The standard North American onboard charger accepts single phase 120 or 240-volt sources at a rate of up to 10 kW. Included adapters allow the car to charge from a standard 120 volt outlet, a 240 volt NEMA 14-50 outlet, a 208 volt leg to leg of a 208Y/120V 3-phase configuration, a 277 volt leg to neutral of a 480Y/277V 3-phase configuration and SAE J1772 public chargers. An optional upgrade for a second 10 kW onboard charger supports a total of up to 20 kW charging from an 80 amp available Tesla Wall Connector. The North American connector uses a proprietary Tesla design.

Charging times vary depending on the battery pack's state-of-charge, its overall capacity, the available voltage, and the available circuit breaker amperage. From a 120 volt/15 amp household outlet, the range increases by 3.75 miles (6 km) for every hour of charging. From a 10 kW, NEMA 14-50 240 V/50 A outlet (like those used by RVs or standard cooking ranges), the charge rate is 28.75 miles (46 km) per hour. Using Tesla's 20 kW, 240 V High Power Wall Connector increases the rate to 57 miles (92 km) per hour if the car is configured with dual chargers (20 kW).

Europe/Asia-Pacific

The standard European charger accepts single phase 230 V at up to 7.6 KW, three phase 230 V or 400 V at up to 11 KW. The Type 2 connector on the car directly accepts "Mennekes" IEC 62196 charging from public stations at up to 400 V, and included adapters allow the car to charge from standard continental European outlets and IEC 60309 230 volt (blue 3-pin) or 400 volt (red 5-pin) outlets, depending on region. The addition of a second charger supports charging at up to 22 kW (up to 16.5 kW with new charger for 3 phase 400 V 24 A on new front fascia Model S), providing up to 70 miles (110 km) (50 miles (80 km) on new front fascia Model S) of range per hour of charge.

Suspension

The Model S has independent coil spring suspension on all four wheels - front double wishbone, virtual steer axis control arm and rear independent multilink. As an extra-cost option, the car is available with self-leveling, height-adjustable air suspension. This is accomplished via adjustable Bilstein shock absorbers controlled by the driver. The car is meant to lower itself at highway speed and raise itself to traverse steep driveways and rough terrain, despite the low 6-inch ground clearance and rather long 116-inch wheelbase.

Because, in the Tesla, electronic systems can be upgraded by "over-the-air" download, rather than recall, the suspension system has been changed retroactively on several occasions. During the 2013 'fire investigation', NHTSA asked Tesla to disable the car's ability to lower itself at speed on the theory that a ground clearance below 6 inches might cause the batteries underneath the car to contact road debris. In September 2014, Tesla upgraded the height adjustment feature for Model S cars equipped with air suspension to remember locations that require higher clearance such as those with potholes and steep driveways, and automatically adjusts to avoid them.

Autopilot

Beginning in September 2014, Model S vehicles come equipped with a camera (supplied by Mobileye) mounted at the top of the windshield, forward looking radar (supplied by Bosch) in the lower grille, and ultrasonic acoustic location sensors in the front and rear bumpers that provide a 360-degree buffer zone around the car. This equipment allows Model S to detect road signs, lane markings, obstacles, and other vehicles. In addition to adaptive cruise control and lane departure warning, a "Tech Package", together known as Autopilot, option enables semi-autonomous drive and parking capabilities. All Model S cars sold since October 2014 have the option to enable Autopilot, which allows limited hands-free driving. Autopilot-enabled cars receive software wirelessly, the same as other car software updates.

According to Elon Musk, the Model S was designed to be a computer on wheels: "We really designed the Model S to be a very sophisticated computer on wheels. Tesla is a software company as much as it is a hardware company. A huge part of what Tesla is, is a Silicon Valley software company. We view this the same as updating your phone or your laptop." Full autonomy is "really a software limitation: The hardware exists to create full autonomy, so it's really about developing advanced, narrow AI for the car to operate on."

Fatal accident

The first known fatal accident involving a Model S occurred when the autopilot was active in Williston, Florida on 7 May 2016. In June 2016, the U.S. National Highway Traffic Safety Administration (NHTSA) opened a formal investigation into the accident working with the Florida Highway Patrol. According to the NHTSA, preliminary reports indicate the crash occurred when a tractor-trailer made a left turn in front of the Tesla at an intersection on a non-controlled access highway, and the car failed to apply the brakes. The NHTSA's preliminary evaluation was opened to examine the design and performance of any automated driving systems in use at the time of the crash, which involves a population of an estimated 25,000 Model S cars.

According to Tesla, "neither autopilot nor the driver noticed the white side of the tractor-trailer against a brightly lit sky, so the brake was not applied." The car attempted to drive full speed under the trailer, "with the bottom of the trailer impacting the windshield of the Model S." Tesla also stated that this was Tesla's first known autopilot-related death in over 130 million miles (208 million km) driven by its customers while Autopilot was activated. According to Tesla there is a fatality every 94 million miles (150 million km) among all type of vehicles in the U.S. In January 2017, the NTSB report concluded Tesla was not at fault since the driver in the crash had seven seconds to see the truck and take action; the investigation revealed that the Tesla car crash rate dropped by 40 percent after autopilot was installed.

Instrument panel

The instrument panel is a 12.3-inch (31 cm) liquid-crystal display electronic instrument cluster that indicates speed, power usage, charge level, estimated range and active gear, as well as Nav directions (driven by Garmin). The gearbox can be set to drive, neutral, reverse, and park. The infotainment control touchscreen is a 17-inch (43 cm) multi-touch panel divided into four areas. A top line displays status symbols and provides shortcuts to Charging, HomeLink, Driver Profiles, vehicle information (software version and the vehicle identification number) and Bluetooth. The second line provides access to several apps including Media, Nav (driven by Google Maps, and thus is separate from the Nav on instrument panel), Energy, Web, Camera and Phone. The central main viewing area displays the (two) active apps, subdivided into upper and lower areas. (Most apps can be expanded to take up the entire area). At the bottom is access to various controls and settings for the vehicle such as doors, locks and lights as well as temperature controls and a secondary volume control.

The instrument cluster and the infotainment panel are driven by separate Nvidia Tegra 3 3D Visual Computing Modules. Tesla was the first company to ship this technology. (Audi later delivered this technology in its 2013 model year in Europe, and in North America in 2014.) The Tegra system on a chip (SoC) integrates eight specialized processors, including a multi-core ARM CPU, a GPU, and dedicated audio, video and image processors. Nvidia claimed that it consumes 2% of the energy of a typical CPU.

The navigation system uses GPS and a mix of Garmin and Google Maps route guidance. The map display on the 17-inch screen requires a constant Internet connection, so navigation is limited in areas without mobile network coverage. The Nav on the instrument panel is loaded on the car and does not need Internet access to function. Update 6.2 features automatic nav guidance to charging stations if range is insufficient.

Enthusiasts have developed the Open Vehicle Monitoring System (OVMS) which allows the owner to remotely observe a variety of different vehicle operating parameters, such as battery state of charge, typically using a smartphone. Some switchgear used are Mercedes parts, such as window switches, cruise control lever, and drive selector.

According to Elon Musk, the Model S runs on the open-source Linux operating system. In 2014, Autoblog reported that Tesla Models S owners had determined via the car's combined diagnostics and Ethernet port that a Ubuntu system controlling the central touchscreen is connected to the car's internal Ethernet. The same users determined that another Ubuntu system controlling the dashboard/navigation screen also is connected to the internal network, together with a third computer of unknown type with an unknown function.

Options

All versions of the Model S have the same body and normally seat five passengers. An optional folding third row becomes a rear-facing two-place child seat with a five-point harness. Consumer Reports said that the 7-passenger capacity afforded by this option is larger than any other electric vehicle, though not really the same as a full-size SUV that seats 7 adults. The two extra seats are only for children over 37 in (940 mm) tall and weighing between 35 to 77 lb (16 to 35 kg), which the magazine described as "a narrow size range. It's too big for smaller kids, and larger ones won't fit under the sloping glass window." The seats fold away under the rear cargo area, which Consumer Reports said is a "cumbersome and awkward" operation, though for the third row seats are "useful for occasional extra passengers when your kids bring friends along", provided the driver had planned ahead and left the cargo area empty. Though the rear-seat option includes a stronger rear bumper, the magazine also said that seating behind the rear axle on the Model S, like any third-row seat, is an additional risk in severe rear impacts, though these are relatively rare.

Cargo space is available under the front hood, which Tesla calls the "frunk". In October 2014, the upgraded Model S P85D, D for dual, was introduced. The upgraded version has two electric motors, one driving the rear wheels as in prior versions, and one driving the front wheels. The dual motor version will be available also for the basic 85 kWh versions. The rear wheel drive version of the P85 was removed, and the dual motor option is not available for the 60 kWh version.

The 2015 model year update introduced electromechanical brakes. In 2016, the 85 kWh and later 90 kWh battery was discontinued from all markets. A glass roof with no horizontal roof bar between the B-pillars was introduced in late 2016. Before adding an all-glass roof option for the Model S, possible roof options was: body colored roof, a black painted roof, or the panoramic sunroof.

Vehicle warranty and maintenance

The Model S is covered by a 4-year, 50,000 mi (80,000 km) limited warranty, that includes all standard equipment, the transmission and the complete powertrain (excluding tires). The warranty can be extended an additional 4 years or 50,000 miles (80,000 km) beyond the original terms. Warranty coverage includes a complementary loaner car--a Performance 85 or Tesla Roadster--when service is required. In April 2013, Tesla announced that a previously mandatory annual vehicle inspection and maintenance fee would be made optional, and would not be required to maintain warranty coverage. If chosen, the fee covers a complete inspection, tire alignment, new brake pads, hardware upgrades and miscellaneous other maintenance items as needed.

The battery and drive unit are covered for eight years or 125,000 miles (200,000 km in metric countries) for the 60 kWh base model, or eight years and unlimited distance for all 70 and 85 kWh models. The unconditional battery warranty covers everything except deliberate damage, even including user error. However, loss of battery capacity over time or usage is not covered under warranty.

Environmental impact

Tesla's lithium-ion batteries contain small amounts of nickel and cobalt, the extraction and refining of which has been identified by the EPA as having a high potential for environmental impact due to the toxicity of the refining processes. Tesla claims to recycle all the battery packs that are returned to the company, and is optimistic that its Gigafactory 1, once fully operational, will be capable of recycling a significant part of the elements from old batteries, approaching a "closed loop" in which old batteries are turned into new batteries. Tesla has worked with ToxCo/Kinsbursky in the US since 2008 and Umicore in Europe to recycle worn out RoHS batteries, which will be performed at the new factory. While ToxCo/Kinsbursky uses a hydro-metallurgical process to recover lithium from the battery, Umicore only recovers nickel and cobalt for reuse in new batteries and turns approximately 30% of the battery, including the battery's lithium, into slag that is sold to steel refiners and cement manufacturers.

In February 2014, the Automotive Science Group (ASG) published the result of a study conducted to assess the life-cycle of over 1,300 automobiles across nine categories sold in North America. The study ranked the Model S as the best environmental performer in the 2014 full-size cars category. Based on the assessment of life-cycle environmental footprint, the study concluded that the increased environmental impacts of manufacturing the vehicle are more than offset with increased environmental performance during operation. For the assessment, the study used the average electricity mix of the U.S. grid in 2014. The Nissan Leaf had the smallest life-cycle environmental footprint of any model year 2014 automobile available in the North American market. The Automotive Service Group is an advertising-supported website and marketing consulting company founded by a Seattle couple in 2009.

In 2012, a study by the Union of Concerned Scientists found that an electric vehicle in the United States with similar efficiency to the Model S is responsible for the production of the same amount of CO₂ as a gasoline-powered car that gets 34 to 115 MPG, depending on the source of electricity in the region in which the car is being charged. The study estimated that nearly half of Americans lived in regions where an electric vehicle would result in less emissions than a 50 MPG hybrid vehicle. A 2015 study by Union of Concerned Scientists found that in the US regions where the Model S is popular, the 68% higher manufacturing emissions are offset within a few years of average driving. During their life-cycle, EVs emit about half the amount of comparable fossil cars. The report assumes electric materials are recycled at a rate similar to other cars, but excludes the problem of battery disposal, "because there are sparse data on how industry is currently recycling batteries or intends to do so in the future".

Charging

Home charging

Tesla recommends that the primary method of charging be overnight charging at home, "just like your mobile phone". Tesla Model S vehicles come with the Mobile Connector, which allows charging at up to 40 amps and includes adapters for connecting to a variety of electricity sources. In North America, adapters for 120-volt NEMA 5-15 and 240-volt NEMA 14-50 outlets, as well as an adapter for SAE J1772 charging stations, are included. In Europe, adapters for CEE red 3P+N+E, CEE blue 2P+E, CEE 7, and BS 1363 are available (inclusion varies by country), and an adapter cable for connecting to chargers with a Type 2 connector is also included.

The Tesla Wall Connectors is available for installation at a home or business, and it allows charging at up to 19.2 kW in North America and 22 kW in Europe (although charging the vehicle at 11.5 kW requires the High Amperage Charger option on the vehicle).

Destination charging

The Tesla Destination charging network is a network of businesses that have installed Tesla Wall Connectors. These units are provided to the businesses by Tesla for free or at a heavily discounted price, although the business is responsible for the cost of electricity. As of April 2017, over 5,000 businesses were participating in the program, and Tesla plans to increase that number to 15,000 by the end of 2017. Not all destination chargers are available to the public, as some businesses limit them to customers or residents only.

Tesla vehicles are also able to utilize public charging stations using the SAE J1772, Type 2, and CHAdeMO charging standards via adapters. SAE J1772 and Type 2 adapters are included in the appropriate regions, while the CHAdeMO adapter is available for purchase.

Tesla Superchargers

In 2012, Tesla began building a network of 480-volt charging stations, called Tesla Superchargers, to facilitate long-distance travel. As of June 2017, 861 Supercharger stations, with 5,655 chargers, were operating worldwide, and Tesla plans to have other 10,000 chargers installed by the end of 2017. The Tesla network is usable only by Tesla vehicles, which are engineered for compatibility.

The Supercharger is a proprietary DC rapid-charging station that provides up to 145 kW of power, giving 85 kWh vehicles an additional 180 mi (290 km) of range in about 15-30 minutes. Older 60 kWh models may have reduced charge rate.

Along the West Coast corridor the Superchargers's grid access is assisted by a solar carport system (some including a battery of a few hundred kWh) provided by SolarCity. All Tesla Supercharger stations were originally planned to be assisted by solar power.

Supercharging hardware is a standard on all vehicles sold by Tesla, except the original Roadster. In November 2013, Tesla reported that 90% of its customers had opted for supercharging capability. As of April 2016, there are over 620 operating Superchargers around the world. Elon Musk said at the unveiling of the Model 3 that that number would be doubled by the end of 2017.

Tesla built 120 kW Tesla supercharger stations to allow long distance travel in North America, Europe, Asia, and Australia. A Supercharger can add up to 125 miles (201 km) of range in 20 minutes and a full charge in approximately one hour assuming a nearly empty 85 kWh battery.

Supercharging hardware and usage is included in all Model S cars except the 60 kWh model had its supercharging disabled by software; a customer had to pay an extra fee to enable supercharging.

The first Supercharger corridor opened in October 2012, with six stations placed along routes connecting San Francisco, Lake Tahoe, Los Angeles and Las Vegas. A second corridor opened in December 2012 connecting Washington, D.C., New York City, and Boston; it includes three stations located in highway rest areas in Delaware and Connecticut.

The first Tesla Superchargers in Europe opened in Norway in August 2013. Tesla next focused on Germany and the Netherlands were covered by mid-2014. Switzerland, Belgium, Austria, Denmark and Luxembourg were covered by the end of 2014. Stations are planned to be within 200 mi (320 km) for about 90% of the population in France, England, Wales and Sweden by the end of 2014.

Battery swapping

Tesla designed the Model S to allow fast battery swapping, which also facilitates vehicle assembly. At a demonstration Tesla showed a battery swap operation taking around 90 seconds, about half the time it takes to refill an empty gas tank. In June 2013, Tesla announced plans to deploy Tesla stations, with facilities to support battery pack swaps, although by June 2015 Tesla said that it was unlikely that more battery swap stations would be added. Battery swapping was planned to be deployed along Interstate 5 in California between San Francisco to Los Angeles, followed by the Washington, D.C. to Boston corridor. Each swapping station costs US$500,000 and stocks about 50 batteries. Owners can pick up their original battery pack fully charged on the return trip, which is included in the swap fee.

Tesla's only battery swap station is located at Harris Ranch near Selma, California, and was available for pilot testing in late December 2014. As of 2015, Tesla says they have hundreds of cars in the battery swap program, although few owners were interested in using the service. In June 2015, Tesla said that it was unlikely that more battery swap stations would be added due to lack of demand for swapping.

Editions

Tesla allocated the first 1,000 units to its Signature and Signature Performance limited edition configurations, equipped with the 85 kWh battery pack. Tesla does not make a convertible Model S.

A custom Model S was designed for the Oceanic Preservation Society in collaboration with Obscura Digital, and was used to project images of endangered animals to help educate the public about the ongoing Holocene mass extinction, as featured in the 2015 documentary Racing Extinction.

Sales and markets

Global

Tesla reported 520 reservations for the Model S during the first week they were available and by December 2012, a total 15,000 net reservations (after deliveries and cancellations) had been received by year-end. The special edition Model S Signature model was sold out before deliveries began in June 2012, and according to Tesla all models were sold out for that year shortly after. A car ordered in May 2012 would be delivered in early to mid-2013.

Initially Tesla expected to reach global sales of 35,000 units in 2014, but in November 2014 reduced its sales target to 33,000 units due to a deficit in production of 2,000 units during the third quarter of 2014. The company expected its annual production to increase by over 50% in 2014 to 35,000 units, and another increase of 50% in 2015. Tesla set a target of between 50,000 and 52,000 deliveries for Model S and Model X cars in 2015, and delivered 50,658 units. Tesla plans to deliver 80,000 to 90,000 new Model S and Model X vehicles in 2016.

2012

U.S. deliveries began June 2012. Deliveries of the 60 kWh model were rescheduled from November 2012 to January/February 2013. A total of 2,650 cars were delivered in North America in 2012.

2013

During the first six months of 2013, 10,050 were delivered. The Model S was released in Europe in early August 2013, and the first deliveries took place in Norway, Switzerland and the Netherlands, and by November 2013, the Model S was on sale in 20 countries.

Sales totaled about 22,477 units in North America and Europe, surpassing Tesla's annual sales target of 21,500 units. Global cumulative sales passed the 25,000 unit milestone in December 2013. By the end of 2013, according to Elon Musk, Norway and Switzerland became the company's largest per capita sales markets.

2014

Retail deliveries in China began in April 2014. The right-hand-drive model was released in the UK in June 2014, followed by Hong Kong in July 2014 and Japan in September 2014. Deliveries in Australia began in December 2014.

Global cumulative sales of the Model S passed the 50,000 unit mark in October 2014. A total of 31,655 units were sold worldwide in 2014, allowing the Model S to rank as the world's second best selling plug-in electric vehicle after the Nissan Leaf that year. In 2014 about 55% of Model S deliveries took place in North America, 30% in Europe, and 15% in the Asia-Pacific market.

2015

A total of 21,577 units were sold worldwide during the first half of 2015, of which, 11,532 were delivered during the second quarter alone, up about 52% over the same quarter the previous year. As of June 2015, the Model S was sold in 30 countries. A total of 11,597 Model S cars were delivered during the third quarter, up about 49% over the same quarter in 2014. A total of 17,272 Model S were delivered during the fourth quarter, up 76% over the same quarter the previous year, and setting a new record for the most cars delivered in a quarter. Global Model S sales passed the 100,000 unit milestone in December 2015, three years and a half after its introduction. A total of 50,446 Model S sedans were sold globally in 2015, making the Model S the world's best-selling plug-in electric car in 2015, ahead of the Nissan Leaf (about 43,000 units).

As of December 2015, a total of 107,228 Model S sedans had been sold worldwide since its introduction, ranking as the world's second best selling plug-in car ever after the Nissan Leaf (200,000). The United States continued as the largest market with 63,161 units sold. Norway listed as the Model S largest overseas market, with 10,062 new units registered, followed by China with 5,524 units registered through September 2015, and the Netherlands with 4,382 units registered at the end of December 2015.

2016

Model S global sales totaled 12,420 units during the first quarter of 2016. Sales during the second quarter of 2016 were lower than anticipated by Tesla, with 9,764 Model S cars delivered worldwide during the quarter. Although production was up 20% from the previous quarter, the number of vehicles in transit at the end of June 2016 was much higher than expected (5,150 including Model X cars), representing 35.8% of the number of cars delivered in the quarter (14,402 vehicles including the Model X).

Deliveries in the third quarter of 2016 totaled 16,047 units, for cumulative sales of 38,231 Model S cars during the first nine months of 2016, allowing the Model S to rank as the world's top selling plug-in car during this period, just ahead of the Nissan Leaf. Global Model S sales passed the 150,000 units in November 2016, four years and five months after its introduction, with the largest share, 57%, in the US. With an estimated 12,700 units delivered during the fourth quarter of 2016, sales totaled about 50,931 units in 2016, making the Model S the world's top selling plug-in car for the second year running. The United States had about 29,156 units delivered, followed by China with 6,334, surpassing Norway as the largest Model S overseas market.

As of December 2016, about 158,159 Model S cars have been sold worldwide since its introduction, making the Model S the world's all-time second best-selling plug-in electric car after the Nissan Leaf (250,000), and ahead of the Volt/Ampera family of plug-in hybrids (134,500).

2017

About 39,515 Model S cars were sold globally during the first three quarters of 2017. Of these, about 19,630 were delivered in the United States (49.7%).

Sales by country

The following table shows sales by year for the top selling countries through December 2016:

Asia/Pacific

Australia

The first nine units were delivered in Sydney on December 9, 2014. Tesla also opened its first store and service centre in St Leonards, and its first Supercharger station at Pyrmont in December 2014. Initially, only two versions were available, the 60 and the 85. The Model S P85D had deliveries scheduled to begin in June 2015.

As of December 2014, a total of 65 Model S cars were registered in New South Wales and only four in Victoria. At the end of March 2015, registrations totaled 119 in New South Wales and 54 in Victoria. Although there were no sales figures reported for Tesla in other states, the combined sales of these two states alone were enough for the Model S to rank as the top selling all-electric car in the country for the first quarter of 2015, ahead of the BMW i3 (46) and the Nissan Leaf (31).

China

The first deliveries took place on April 22, 2014. The Model S has the same standard equipment as the continental European version, but was adapted to provide larger back seats because the car was expected to be driven by a chauffeur. Only two versions with an 85 kWh battery pack are available in the Chinese market, standard and performance.

Chinese sales up to June 2014 were estimated between 1,000 to 1,300 units. JLWarren Capital, an equity firm, estimated that about 2,800 Tesla Model S cars have been imported to China by mid September 2014, but only 432 had received the license plates. According to a Tesla spokesman, the major reasons for the discrepancy could be that registration rules were holding deliveries in Shanghai, and Tesla only recently was able to start delivering the electric cars to customers who bought them in Shanghai. Secondly, many Chinese customers have delayed taking possession of their Model S car while waiting for the government to add the Tesla to the list of electric vehicles exempt from its 8% to 10% purchase tax. As of December 2014, Tesla had imported 4,800 Model S cars, but only 2,499 of those vehicles were registered for road use in China.

Tesla's CEO expressed disappointment with the Chinese sales, as stock continued to be high by early 2015. As sales improved, Model S sales reached 2,147 units representing an 80% share of the imported plug-in hybrid or electric car segment in China for the first half of 2015. Sales totaled 3,025 units during the first nine months of 2015, for cumulative registrations of 5,524 units through September 2015. Tesla's initial sales target for 2015 was 10,000 units. Sales totaled 6,334 units in 2016.

Hong Kong

Sales of the Model S began in July 2014. According to Tesla, as of June 2015, Hong Kong has the world's highest density of Tesla superchargers, with eight stations comprising a total of 36 supercharger stalls. This infrastructure allows most Model S owners to have a supercharger within 20 minutes' drive. Sales totaled 2,221 units in 2015, and by August 2016 about 80% of 5,800 EVs in Hong Kong were Teslas.

Europe

Retail deliveries began in Europe in early August 2013, in Norway, Switzerland and the Netherlands. The two biggest markets for the Model S in Europe are Norway and the Netherlands. The Model S, with about 3,900 units sold, ended 2013 as the third-best selling all-electric car in Europe after the Nissan Leaf and the Renault Zoe. A total of 8,734 Model S cars were sold in 2014, representing a market share of 15.5% of new all-electric passenger car sales in Europe, and again allowing the Model S to rank as the third best selling all-electric car in Europe after the Leaf and the Zoe. Accounting for sales during the first nine months of 2014, the Model S outsold the Audi A8, BMW 7 Series and Jaguar XJ, ranking second in the European luxury vehicle segment after the Mercedes-Benz S-Class.

European Model S sales in 2015 totaled 15,515 units, ranking second after the Renault Zoe (18,727) and ahead of the Leaf (15,455). The Model S captured 15.9% of the European all-electric segment sales in 2015. The Model S topped the European luxury car segment in 2015, ahead of the Mercedes-Benz S-Class (14,990), the segment's leader in previous years. Norway was the largest market in 2015 with 4,039 units sold. Cumulative Model S sales in Europe totaled 28,149 units by the end of 2015.

Czech Republic

A total of 23 units were sold during 2014.

Denmark

During its first full month in the Danish market, the Model S was the top selling electric vehicle with 42 units sold. Sales were 112 units in 2013 and 460 in 2014. Model S sales constituted 35% of the sales of luxury cars by mid 2014. A Model S was tested as a taxi, but high price and low range made the project uneconomical. When the AWD model was announced in Autumn 2014, used Model S were sold fast at high price.

In October 2015, the Danish Parliament approved to phase out the tax exemption for electric vehicles, and customers rushed to order the Model S before the price increase. It became the most sold car of any kind in Denmark in December 2015, with 1,248 cars delivered that month, out of 1,573 electric cars sold in December. This is the first time ever that an electric car is the best selling car in Denmark. The Model S comprised 98% of luxury cars sold in Denmark in 2015. Cumulative sales in the country reached 3,308 units through December 2015, of which, a record of 2,736 units were sold in 2015. Sales plummeted to 78 units in 2016 after the phasing out of the country's tax break for electric vehicles at the end of 2015.

Germany

The company announced that by November 2013 the first Tesla Supercharger stations would open between Munich and Stuttgart, Munich and Zurich, Switzerland, and Cologne and Frankfurt. Tesla planned to cover more than 50% of Germany by the end of March 2014, and 100% by the end of 2014. Germany would then have the most Superchargers per capita of any country. By late 2013 Tesla announced a goal to sell 10,000 Model S in Germany in 2015.

Registrations totaled 815 units in 2014, representing 2.7% of the luxury segment sales in the country. As of November 2015, cumulative registrations totaled 2,354 units. A total of 1,474 Model S cars were registered in Germany in 2016.

Netherlands

The first deliveries in the country occurred on August 22, 2013, at Tesla's European Distribution Center in Tilburg. A total of 1,194 units were sold in 2013. After the end of the registration tax exemption, sales fell significantly, and only 262 units were sold during the first four months of 2014. In April 2014 the Schiphol Group announced that three companies were selected to provide all-electric taxi service in Amsterdam Airport Schiphol. The concessions started on June 1, 2014 and service is provided with 100 Tesla Model S cars, which jointed service to the electric buses and hybrid cars already operating at the airport.

Sales in 2015 totaled 1,805 units, and declined to 1,693 in 2016. As of October 2016, combined registrations of the Model S (5,681) and the Model X (250) represented 48.6% of the 12,196 all-electric cars on Dutch roads at the end of that month. The Model S remained as the all-time top selling all-electric car in the Netherlands with 6,049 cars registered at the end of December 2016.

Norway

The first delivery of a Model S in Europe took place in Oslo on August 7, 2013. By the end of August 2013, Europe's first six charging stations were opened, in Lyngdal, Aurland, Dombås, Gol, Sundebru and Lillehammer. That month 186 units were delivered, ranking second among all-electric cars behind the Nissan Leaf (448 units). Sales surged in September totaling 616 units, beating the Leaf and achieving an overall new car market share of 5.1%.

In 2013, a five-month waiting list emerged creating a used market. Sales dropped to 98 units in October, before jumping back to 527 units in November, ranking it number two in new car registrations after the Volkswagen Golf. In December, sales of 553 units made it the top-selling new car again and capturing a 4.9% market share of new car sales. With less than five months of sales, the Model S ranked 20th for the year with a market share of 1.4% of Norwegian new car sales, Tesla's largest in Europe.

The Model S topped the monthly sales ranking for a third time in March 2014, with 1,493 units sold, breaking the 28-year-old monthly sales record, surpassing the Ford Sierra, which sold 1,454 units in May 1986. Sales totaled 2,056 Model S cars during the first quarter of 2014, making the Model S the best selling new car in Norway during this period. The Model S captured a 5.6% market share of new car sales and 38.8% of the new plug-in electric car segment during this quarter. By the end of 2014, the Model S ranked as the fifth best selling new car in the Norwegian market, with 4,040 units registered and a market share of 2.8% of new car sales in the country that year.

As of July 2014, Norway ranked as Tesla's largest overseas market, with an average of 436 Model S sedans sold per month since August 2013. In comparison, the average in the United States was about 1,630 units delivered per month since the electric car went on sales in 2012. As of December 2015, Norway continued as the second largest Model S market by volume, with about 9.4% of cumulative global sales. After a stagnant year of 4,000 plus deliveries for 2015, deliveries of Tesla dropped 54% in the first quarter and 52% in the second quarter of 2016 in Norway. Tesla Model S registrations in Norway totaled 2,051 new units in 2016. Since its introduction, a total of 12,113 new Model S cars have been registered in Norway through December 2016.

Switzerland

Retail deliveries began in August 2013, and a total of 213 units were registered in 2013. The Model S, with 496 units registered, ranked as the top selling plug-in electric car in the country in 2014. With 835 units sold during the first seven months of 2015, the Model S outsold combined Swiss sales of the luxury segment including such models as the Mercedes S-Class, Audi A8 and BMW 7 Series during the same period. Cumulative Model S sales totaled 3,060 units up until June 2016, which includes units sold in Liechtenstein.

United Kingdom

Deliveries began in June 2014, and a total of 698 units were registered in the UK by the end of 2014. Model S owners are also exempted from the London congestion charge. During the first half of 2016, slightly more Model S cars were registered in the UK than in Norway, the largest Model S market in Europe. During the first six months of 2016 a total of 1,263 Model S sedans were registered in the UK and 1,248 in Norway. A total of 3,907 Model S sedans were registered in the UK at the end of September 2016.

North America

Canada

The first Model S sedans were delivered in December 2012. Cumulative sales totaled 3,590 units as of December 2015, and ranks as the second best-selling plug-in car in the country ever after the Chevrolet Volt (5,415) and ahead of the Nissan Leaf (3,198). The Model S was the top selling plug-in electric car in Canada in 2015 with 2,010 units sold.

Mexico

Retail sales began in Mexico City in December 2015. Initially, no Supercharger stations are available in the country.

United States

The first delivery took place on June 1, 2012. Deliveries for retail customers in the United States started on June 22, at a special event held at the Tesla Factory in Fremont, California. The first 1,000 production units were Signature and Signature Performance limited editions equipped with an 85 kWh battery pack. Cumulative sales passed the 50,000 unit milestone in early July 2015.

About 2,620 units were sold in the U.S. during 2012 out of 2,650 units delivered in North America. California is the largest American regional market for the Model S. In March 2013, Tesla reported the delivery of the 3,000th Model S in California, representing around 50% of US sales to that date. During the first quarter of 2013 the Model S ranked as the top selling plug-in electric vehicle in the U.S. with about 4,900 units delivered, followed by the Chevrolet Volt with 4,244 units. During 2013, the Model S was called as the least stolen car in the United States by the Value Walk financial website, with a theft rate of 0.15 per 1,000 units produced. By comparison, the U.S. average is 3.51 cars stolen per 1,000 produced.

According to Edmunds.com, between January and August 2013 the Model S achieved a high market share of new car sales among the U.S. most expensive ZIP codes, as rated by Forbes, led by California. Atherton ranked first with a 15.4% share, followed by Los Altos Hills with 11.9%, and Portola Valley with 11.2%. During this period the Model S had the highest number of new passenger car registrations in 8 of the 25 most expensive American ZIP codes. With 8,347 units sold in 2013, it was the third-best selling luxury car in California (after the Mercedes-Benz E-Class and BMW 5 Series sedans), with a 9.8% share of the Californian luxury and sports segment. As of November 2013, the Model S was available nationwide, with California having 48% share U.S. sales.

American sales totaled about 18,650 units in 2013, placing the Model S as the third selling plug-in electric car after the Chevrolet Volt (23,094) and the Nissan Leaf (22,610). Also in 2013, the Model S was the top seller in the full-size luxury sedan category, ahead of the Mercedes-Benz S-Class at 13,303. In 2014, 16,689 Model S sedans were delivered, down 10.5% from 2013, but the electric sedan ranked again as the third best selling plug-in car in the U.S.

In 2015 the Model S ranked as the top selling plug-in electric car in the U.S, with 25,202 delivered, surpassing both the Leaf (17,296) and the Volt (15,393). The Model S was also the country's best-selling car in the large luxury segment among comparably priced four-door sedans, ahead of the Mercedes-Benz S-Class (21,934) and BMW 7 Series (9,292). Registrations in California totaled 10,723 units in 2015, representing a 12.1% market share of the state's luxury and sports segment, making the Model S the third best selling car in the segment after the Mercedes-Benz E-Class (12,324) and BMW 5 Series (11,133). By the end of 2015, cumulative sales in the American market represented almost 60% of Model S global sales since its introduction.

Tesla reported 9,156 units sold nationwide in the third quarter of 2016, up 59% from the same quarter in 2015, allowing the Model S to led national sales in the large luxury car segments, representing almost a third of the segment sales, and ahead of the Mercedes-Benz S-Class (4,921) and the BMW 7 Series (3,634). The Model S was the top selling plug-in electric in the American market for the second year in a row with an estimated 29,156 units delivered in 2016. Registrations in California totaled 11,326 units in 2016, representing a 14.1% market share of the state's luxury and sports segment, making the Model S the second best selling car in the segment after the Mercedes-Benz E-Class (11,684) and ahead of the BMW 5 Series (10,551). According to Wards's Auto, the Model S topped the American upper luxury segment in 2016, followed by the Mercedes S-Class (18,803) and the BMW 7-Series (12,918). An estimated 92,317 Model S cars have been sold in the United States up until December 2016, representing about 57% of Model S global sales through November 2016.

Model S sales in the American market passed the 100,000th unit mark in early June 2016, achieving this milestone in less time since inception than both the Chevrolet Volt and the Nissan Leaf. An estimated 12,600 Model S cars have been sold in the U.S. during the first seven months of 2017, down 10.6% year-on-year.

Owners profile

Owners of the Model S are overwhelmingly male and over 45 years old.

Retail sales model disputes

Tesla sells its cars directly to consumers without creating a dealer network, as other manufacturers have done and as many states require by legislation. In support of its approach, the company has fought legal and legislative battles in Ohio, New Jersey, New York and other states. With law changes in recent years in New Jersey, New York, Maryland, Ohio, and Pennsylvania the Tesla direct sales model is permitted in 22 states as of March 2015. As of May 2015 the sales procedure in other states such as Texas is somewhat different with the Tesla salesperson being prevented from discussing prices, the actual sale having to be made online and the sales tax having to be paid up front. Delivery of a Tesla car to a Texas address is no different than in other states. Consequently, while Tesla showcases and sells its cars directly to the consumer in Tesla Stores abroad, it operates a mix of Tesla Stores and Tesla Galleries in the US.

Safety

Safety features

The Model S has a 5-star safety rating from both Euro NCAP and the U.S. National Highway Traffic Safety Administration (NHTSA). Only two other cars have earned the same recognition since 2011 (when the NHTSA introduced its latest rating scheme).

However, in July 2017, the Insurance Institute for Highway Safety (IIHS) found that during front crash tests, the Model S safety belts let the driver's torso move too far forward, resulting in the head striking the steering wheel hard through the airbag. This problem was already pointed out in one of the IIHS's earliers tests, to which Tesla responded they would improve their safety belt design, which, according to the IIHS's latest tests, has not been done. The IIHS also gave the Model S the worst possible rating for its headlights. The report caused Tesla to lose 6.4% of its stock value.

First crash with battery fire

The first widely reported Model S fire occurred several minutes after the vehicle hit metal debris on the Washington State Route 167 highway in Kent, Washington on October 1, 2013. The driver "was able to exit the highway as instructed by the onboard alert system, bring the car to a stop and depart the vehicle without injury". He then contacted authorities and, while awaiting their arrival, smoke began coming out the front of the vehicle. The driver stated that he hit something while exiting the HOV lane. Tesla stated that the fire was caused by the "direct impact of a large metallic object to one of the 16 battery modules", and that by design, the modules were separated by firewalls, limiting the fire to "a small section in the front of the vehicle".

The module was evidently punctured by a "curved section" that fell off a truck and was recovered near the accident. Tesla stated that the debris punched a 3-inch (76 mm) diameter hole through the .25-inch (6.4 mm) armor plate under the vehicle, applying force of some 25 tons. Built-in vents directed the flames away from the vehicle so that the fire did not enter the passenger compartment. According to Tesla, the firefighters followed standard procedure; using large amounts of water to extinguish the fire was correct, however, puncturing the metal firewall to gain access to the fire also allowed the flames to spread to the front trunk. Tesla also stated that because the battery pack contains "only about 10% of the energy contained in a gasoline tank", the effective combustion potential of a single module is only about 1% that of a conventional vehicle.

On October 24, 2013, the U.S. National Highway Traffic Safety Administration (NHTSA) announced, "After reviewing all available data, the National Highway Traffic Safety Administration has not found evidence at this time that would indicate the recent battery fire involving a Tesla Model S was the result of a vehicle safety defect or noncompliance with federal safety standards." But the following month, the NHTSA opened a preliminary evaluation to determine "the potential risks associated with undercarriage strikes on model year 2013 Tesla Model S vehicles". On March 28, 2014, NHTSA closed its investigation, claiming that the new titanium underbody shield and aluminum deflector plates, along with increased ground clearance, "should reduce both the frequency of underbody strikes and the resultant fire risk".

Subsequent fires

On November 6, 2013 another fire broke out after a Model S struck a tow hitch on the roadway, causing damage beneath the vehicle. The incidents led Tesla to extend its vehicle warranty to cover fire damage and to apply a software update to increase ground clearance when operating at highway speed.

Another fire incident took place in Toronto, Canada, in early February 2014. The Model S was parked in a garage and was not charging when the fire started. The origin of the fire is undetermined. According to Tesla "in this particular case, we don't yet know the precise cause, but have definitively determined that it did not originate in the battery, the charging system, the adapter or the electrical receptacle, as these components were untouched by the fire".

Starting with vehicle bodies manufactured as of 6 March 2014, all units were outfitted with a triple underbody shield. Existing cars were retrofitted upon request or as part of a normally scheduled service.

On 1 January 2016, a 2014 Model S caught fire in Norway while supercharging unsupervised. The vehicle was totally destroyed but nobody was injured. The fire was slow, and the owner had time to unplug the car and retrieve possessions. An investigation by the Norwegian Accident Investigation Board (AIBN) indicated that the fire originated in the car, but was otherwise inconclusive. In March 2016, Tesla stated that their own investigation into the incident concluded that the fire was caused by a short circuit in the vehicle's distribution box, but that the amount of damage prevented them from determining the exact cause. Tesla stated that the Supercharger detected the short circuit and deactivated, and a future Model S software update would stop the vehicle from charging if a short circuit is detected.

NHTSA safest car

On August 19, 2013, based on NHTSA safety ratings, a Tesla press release claimed that the Model S had achieved the best safety rating of any car ever tested. Tesla stated, "NHTSA does not publish a star rating above 5, however safety levels better than 5 stars are captured in the overall Vehicle Safety Score (VSS) provided to manufacturers, where the Model S achieved a new combined record of 5.4 stars." However, a few days later NHTSA rebutted Tesla's claim, explaining that the rating for the Model S was equal to any other car receiving 5-stars, and claiming that the carmaker did not follow its advertising guidelines.

Recalls

As of May 2017, Tesla has had five recalls for the Model S:

• On June 14, 2013, Tesla issued a recall to all Model S vehicles manufactured between May 10, 2013, and June 8, 2013, due to improper methods for aligning the left hand seat back striker to the bracket, which could weaken the weld between the bracket and frame of the car.
• On January 13, 2014, Tesla recalled Model S vehicles manufactured in 2013, because the adapter, cord, or wall outlet could overheat during charging.
• On November 20, 2015, Tesla announced a voluntary worldwide recall of all of its 90,000 Model S vehicles, in order to check for a possible defect in the cars' front seat belt assemblies. The problem was raised in early November by one customer in Europe. Tesla's resulting investigation was unable to identify a root cause for the failure, and the company decided to examine every single car. Tesla reported that there have been no accidents or injuries related to the problem.
• On January 20, 2017, Tesla recalled Model S from 2012 in January 2017 due to defective Takata airbags. Cars manufactured later (until 2017) have smaller risk, and may also be recalled.
• On April 20, 2017, Tesla issued a worldwide recall of 53,000 (~70%) of the 76,000 Model S and Model X vehicles it sold in 2016 due to faulty parking brakes. The recall caused Tesla stocks to lose two percent of their value and added further questions about the reliability of Tesla's vehicles.

Distance records

A distance record of 670 miles (1,078.3 km) in a P100D was set on August 5, 2017 by Italian drivers, making it the Model S the first production electric car to exceed 620 miles (1,000 km) on a single charge. Previously the record of 560 miles (901.2 km) in a P100D was set on June 20, 2017 by Belgium drivers. Before that the distance record was 452.8 miles (728.7 km) in a Model S. It was made by Norwegian Bjørn Nyland and Morgan Tørvolt on a flat stretch with low traffic around the supercharger in Rødekro, Denmark. All of these records used hypermiling techniques such as front motor only, low speed 24 mph (39 km/h), no air conditioning and minimal use of the brakes. The first record of 423.5 miles (681.6 km) was set during November 2012 by David and Adam Metcalf. These attempts were inspired by a blog written by Elon Musk about the planned range and efficiency of the Tesla Model S, offering a prize for anyone exceeding 400 miles (643.7 km) on a single charge, where it was estimated the 85 kwh model could do it by driving at a constant 36 mph (58 km/h) under ideal conditions.

Controversies

Range limitation

On February 8, 2013, The New York Times published a review by John M. Broder about a trip between Washington, D.C., and Boston using Tesla's Supercharger network. At the time it included only two stations on the East Coast. Broder made a variety of critical claims about the battery's performance in cold weather and the distance between charging stations. The trip ended with the Model S carried by a flatbed truck to the Milford, Connecticut, station.

Tesla responded by publishing logs of the vehicle's charge levels and driving speed that contradicted Broder's account on several factual details. Tesla implied that Broder's behavior forced the car to fail. Broder replied to the criticism in a blog post and suggested that the speed discrepancies may have been because the car had been equipped with 19-inch wheels rather than the specified 21-inch wheels. In the midst of the controversy, a CNN reporter recreated Broder's trip without exhausting the battery. However, two key differences distinguished the two journeys. The weather was about 10 °F (6 °C) warmer and CNN did the trip in one day; the Times let the car sit overnight without being plugged in. A reporter from CNBC also recreated the trip in one day without incidents. One week later, a group of Tesla owners recreated Broder's trip without problems. One owner was delayed because his car failed to charge and required two firmware updates.

On February 18, 2013, The New York Times Public Editor Margaret Sullivan published an editorial stating that Broder took "casual and imprecise notes" of his test drive and did not use good judgment, but she maintained that the article was written in good faith. She also admitted that Broder's vehicle logs were "sometimes quite misleading."

In July and September 2014 tests performed by an independent German car magazine in cooperation with the TÜV (German Association for Technical Inspection) and Tesla owners seemed to reveal issues with the battery's performance. According to the magazine, Tesla did not take up the invitation to repeat the test, and also seemed to refuse to offer vehicles for a second test. A test performed by another German publication ("Die Welt") supported the findings.

Production delay

In 2007, Tesla announced plans to build 10,000 Model S sedans annually starting in 2009. Production was delayed, and Tesla's website later stated that deliveries would start in 2011. However, in January 2010, Musk stated that he expected to launch the Model S sedan "within two and a half years", translating to Q3 2012.

Power dissipation when not in use

Older versions of the system software suffered from power drain issues when the car wasn't being used, with the batteries losing 4.5 kWh overnight (known commonly as "vampire drain"). System software v5.8 (v1.49.30), released December 12, 2013, reduced overnight energy loss substantially, to 1.1 kWh per night, or around 3 miles. In January 2014, Bjørn Nyland, a Model S owner in Norway, recorded a range loss of approximately 20% during a 27-day extended vacation, an indicated range loss of 63 miles (101 km), or 2.3 miles (3.7 km) per day, while stored in frigid temperatures without any charging cable attached.

Consumer Reports' recommendation

In October 2015, two months after naming the Tesla 'the best car ever tested,' Consumer Reports declined to give the Tesla Model S a "recommended" designation, citing too many complaints from owners. Complaints ranged from minor, such as misaligned doors and squeaky body, to severe - things like total drive train replacement and inoperable door handles. Tesla's shares dropped 15%, both because of the magazine's cut and because of concerns over the Tesla Model X luxury SUV. Similarly, Edmunds.com found quality and safety issues in their long-term road test and "amassed quite the repair résumé during the last 17 months." Both Edmunds and Consumer Reports reported issues, including the vehicle stalling while driving.

In their 2016 Annual Auto Reliability Survey, Consumer Reports improved the Model S rating to average reliability, while reporting that the Model X has had significant malfunction issues. The magazine also raised "serious concerns about how some automakers, including Tesla, have designed, deployed, and marketed semi-autonomous technology."

Power discrepancy

The P85D "Insane" was widely reported to have 691 horsepower, but some owners reported 20% less power on dynamometer in various circumstances.

Manufacturers are required by EU law to display power "at full setting of the power controller" (from an external DC source when performing laboratory vehicle approval), but not necessarily to show power limited by battery. Other equipment must be removed, or their power added to the measurement. Actual power available depends on circumstances, as it does for piston cars which until 1972 could be 25-30% less than given.

As of November 2015, Tesla website showed battery-limited combined 463 hp for P85D (532 hp for "Ludicrous"). A lawsuit by 126 owners in Norway was settled in December 2016.

Autonomy limitations

The autonomy functions of the Model S, including Autosteer and Traffic-Aware Cruise Control, have limitations that have led to collisions when the driver becomes inattentive. Tesla warns in the owners manual that drivers always must be aware of road conditions and not rely on the cruise control to prevent a collision, as the system may not detect stationary vehicles or obstacles, bicycles, and pedestrians. However, critics such as scientist Andrew Ng have accused Tesla of being irresponsible by releasing a product with such limitations as it can lull drivers into a false sense of security.

Electrical consumption of Tesla Model S

In early March 2016, a report by Stuff magazine revealed that test performed by VICOM, Ltd on behalf of Singapore's Land Transport Authority had found a 2014 Tesla Model S to be consuming 444 Wh/km (0.715 kW·h/mi), which was greater than the 236 Wh/km (0.38 kW·h/mi) reported by the U.S Environmental Protection Agency (EPA) and the 181 Wh/km (0.291 kW·h/mi) reported by Tesla. As a result, a carbon surcharge was imposed on the Model S, making Singapore the only country in the world to impose an environmental surcharge on a fully electric car. The Land Transport Authority justified this by stating that it had to "account for CO₂ emissions during the electricity generation process" and therefore "a grid emission factor of 0.5g/watt-hour was also applied to the electric energy consumption", however Tesla countered that when the energy used to extract, refine, and distribute gasoline was taken into account, the Model S produces approximately one-third the CO₂ of an equivalent gasoline-powered vehicle.

Later that month, the Land Transport Authority released a statement stating that they and the VICOM Emission Test Laboratory will be working with Tesla engineers to determine if there was a flaw in the test, and a Tesla statement indicated that the discussions were "positive" and that they were confident of a quick resolution.
