Tesla Roadster

The first generation Tesla Roadster is a battery electric sports car based on the Lotus Elise chassis, and was produced by Tesla Motors (now Tesla, Inc.) from 2008 to 2012. The Roadster was the first highway legal, serial production, all-electric car to use lithium-ion battery cells, and the first production all-electric car with a range of more than 200 miles (320 km) per charge. Tesla sold about 2,450 Roadsters in over 30 countries, and most of the last Roadsters were sold in Europe and Asia during the fourth quarter of 2012. Tesla produced right-hand-drive Roadsters from early 2010. The Roadster qualified for government incentives in several nations. According to the U.S. EPA, the Roadster can travel 244 miles (393 km) on a single charge of its lithium-ion battery pack. The vehicle can accelerate from 0 to 60 mph (0 to 97 km/h) in 3.7 or 3.9 seconds depending on the model. It has a top speed of 125 mph (201 km/h). The Roadster's efficiency, as of September 2008, was reported as 120 miles per gallon gasoline equivalent (28 kW⋅h/100 mi) (2.0 L/100 km). It uses 21.7 kWh/100 mi (135 Wh/km) battery-to-wheel, and has an efficiency of 88% on average.

History

Prototypes of the car were officially revealed to the public on July 19, 2006, in Santa Monica, California, at a 350-person invitation-only event held in Barker Hangar at Santa Monica Airport. It was featured in Time in December 2006 as the recipient of the magazine's "Best Inventions 2006—Transportation Invention" award. The first Tesla Roadster was delivered in February 2008 to Tesla early investor, chairman and product architect Elon Musk. The company produced 500 similar vehicles through June 2009. In July 2009, Tesla began production of its 2010 model-year Roadster—the first major product upgrade. Simultaneously, Tesla began producing the Roadster Sport, the first derivative of Tesla's proprietary, patented powertrain. The car accelerates from 0 to 60 mph (0 to 97 km/h) in 3.7 seconds, compared to 3.9 seconds for the standard Roadster. Changes for the 2010 model-year cars included: An upgraded interior and push-button gear selector, including "executive interior" of exposed carbon fiber and premium leather, and clear-coat carbon fiber body accents. Locking, push-button glove box wrapped in leather. A centrally mounted video display screen to monitor real-time data, including estimated range, power regenerated, and the number of barrels of oil saved. Manually adjustable shock absorber response and anti-sway bars. More powerful and immediate heating, ventilation and air-conditioning. More efficient motor and hand-wound stator delivering higher peak power. Sound-deadening measures to reduce noise, vibration and harshness. All of these features, except for the motor, were available either as standard or as add-on option for the non-sport model. Beginning mid-March 2010, Tesla, in an effort to show off the practicality of its electric cars, sent one of its Roadsters ar

Development

After Martin Eberhard sold NuvoMedia to TV Guide, he wanted a sports car, but could not find one to his liking. His battery experience with the Rocket eBook inspired him to develop an electric car. During his search, Eberhard test drove the tzero, a concept car from the small automaker AC Propulsion. Eberhard and Marc Tarpenning, who had also driven the tzero, tried to convince the company to put the car into production, but when they declined, they decided to establish Tesla Motors in Delaware on July 1, 2003, to pursue the idea commercially. South African-born entrepreneur Elon Musk would also test drive a tzero and encouraged AC Propulsion to put the car into production, instead the company connected Musk with Eberhard and Tarpenning. Musk took an active role within the company starting in 2004, including investing US$7.5 million (~$11.9 million in 2024), overseeing Roadster product design from the beginning, and greatly expanding Tesla's long-term strategic sales goals by using the sports car to fund the development of mainstream vehicles. Musk became Tesla's chairman of the board in April 2004. J. B. Straubel joined the company as a principal engineer in March 2004 and became the chief technology officer in May 2005. Musk received the Global Green 2006 product design award for the design of the Tesla Roadster, presented by Mikhail Gorbachev, and he received the 2007 Index Design award for the design of the Tesla Roadster. Before Tesla had developed the Roadster's proprietary powertrain, they borrowed a tzero for use as a development mule and converted the vehicle from lead–acid AGM batteries to lithium-ion cells, which substantially increased the range, reduced weight, and boosted 0 to 60 mph performance. Tesla licensed AC Propulsion's EV power system design and re

Production

Tesla's cumulative production of the Roadster reached 1,000 cars in January 2010. The Roadster is considered an American car though many carry a Vehicle Identification Number beginning with the letter "S", which is the designation for the United Kingdom. Some, however, carry a number starting with "5" appropriate to the US. Parts were sourced from around the world. The body panels came from French supplier Sotira. These were sent from France to Hethel, U.K., where Tesla contracted with Lotus to build the Roadster's unique chassis. The Roadster shares roughly 7% of its components with the Lotus Elise including the windshield, airbags, some dashboard parts, and suspension components. The Roadster's single-speed gearbox was made in Detroit by BorgWarner. Brakes and airbags were made by Siemens in Germany, and some crash testing was conducted at Siemens as well. 30–40% of components were sourced from Taiwan. For Roadsters bound for customers in North America, the glider was sent to Tesla's facility in Menlo Park, California for final assembly, and for Roadsters bound for customers in Europe or elsewhere outside of North America, the glider was sent to a facility at Wymondham near Hethel for final assembly. At these locations, Tesla employees installed the powertrain, which consisted of the battery pack, power electronics module, gearbox and motor. Tesla ordered 2,500 gliders from Lotus, which ceased production in December 2011 when their contract expired. Tesla ended production of the Roadster in January 2012. Timeline. Subsequent to completion of the first production car, the company announced problems with transmission reliability. The development transmission, with first gear enabled to accelerate 0 to 60 mph (0 to 97 km/h) in 4 seconds, was reported to have a life expec

Specifications

=== Motor === The Roadster is powered by a 3-phase, 4-pole, induction electric motor with a maximum output power of 248 hp (185 kW). Its maximum torque of 200 lb⋅ft (270 N⋅m) is immediately available and remains constant from 0 to 6,000 rpm; nearly instantaneous torque is a characteristic of electric motors and offers one of the biggest performance differences from internal combustion engines. The motor is air-cooled and does not need a liquid cooling system. The Sport model introduced during the Jan 2009 Detroit Auto Show includes a motor with a higher density, hand-wound stator that produces a maximum of 288 hp (215 kW). Both motors are designed for rotational speeds of up to 14,000 rpm, and the regular motor delivers a typical efficiency of 88% or 90%; 80% at peak power. It weighs less than 70 pounds (32 kg). Transmission. Starting in September 2008 Tesla selected BorgWarner to manufacture gearboxes and began equipping all Roadsters with a single speed, fixed gear gearbox (8.2752:1 ratio) with an electrically actuated parking pawl mechanism and a mechanical lubrication pump. The company previously worked with several companies, including XTrac and Magna International, to find the right automatic transmission, but a two-gear solution proved to be too challenging. This led to substantial delays in production. At the "Town Hall Meeting" with owners in December 2007, Tesla announced plans to ship the initial 2008 Roadsters with their interim Magna two-speed direct shift manual transmissions locked into second gear, limiting the performance of the car to less than what was originally stated (0 to 60 mph (0 to 97 km/h) in 5.7 seconds instead of the announced 4.0 seconds). Tesla also announced it would upgrade those transmissions under warranty when the final transmission

Energy efficiency

In June 2006, Tesla reported the Roadster's battery-to-wheel efficiency as 110 Wh/km (17.7 kWh/100 mi) on an unspecified driving cycle—either a constant 60 mph (97 km/h)) or SAE J1634 test—and stated a charging efficiency of 86% for an overall plug-to-wheel efficiency of 128 Wh/km (20.5 kWh/100 mi). In March 2007, Tesla reported the Roadster's efficiency on the EPA highway cycle as "135 mpg [U.S.] equivalent, per the conversion rate used by the EPA" or 133 Wh/km (21.5 kWh/100 mi) battery-to-wheel and 155 Wh/km (24.9 kWh/100 mi) plug-to-wheel. The official U.S. window sticker of the 2009 Tesla Roadster showed an EPA rated energy consumption of 32 kWh/100 mi in city and 33 kWh/100 mi on the highway, equivalent to 105 mpg city and 102 mpg highway. The EPA rating for on board energy efficiency for electric vehicles before 2010 was expressed as kilowatt-hour per 100 miles (kWh/100 mi). Since November 2010, with the introduction of the Nissan Leaf and the Chevrolet Volt, EPA began using a new metric, miles per gallon gasoline equivalent (MPGe). The Roadster was never officially rated by the EPA in MPGe. In August 2007, Tesla dynamometer testing of a validation prototype on the EPA combined cycle yielded a range of 221 mi (356 km) using 23.9 kWh/100 mi (149 Wh/km) battery-to-wheel and 33.6 kWh/100 mi (209 Wh/km) plug-to-wheel. In February 2008, Tesla reported improved plug-to-wheel efficiency after testing a validation prototype car at an EPA-certified location. Those tests yielded a range of 220 mi (350 km) and a plug-to-wheel efficiency of 32.1 kWh/100 mi (199 Wh/km). In August 2008, Tesla reported on testing with the new, single-speed gearbox and upgraded electronics of powertrain 1.5, which yielded an EPA range of 244 mi (393 km) and an EPA combined cycle, plug-to-wheel e

Service

Whereas vehicles with internal combustion engines require more frequent service for oil changes and routine maintenance on engine components and other related systems, Tesla's website recommends the owner bring the vehicle in for service "once a year or every 12,000 miles". For other concerns with vehicles, Tesla created a "mobile service unit" that dispatches company-trained technicians to customers' homes or offices in case the owner is experiencing problems. Tesla charges the customer according to the distance the service unit needs to travel: one US dollar per mile roundtrip with a 100-dollar minimum. Technicians drive company vans equipped with numerous tools and testing equipment to do "in the field" repairs, enhancements and software upgrades. Tesla debuted this "house call" approach in the spring of 2009, when the company announced a recall due to a manufacturing problem in the Lotus assembly plant, which also affected the Lotus Elise and other models from the British sports car maker. The first Tesla service center, in Los Angeles, California, was opened on Santa Monica Boulevard on May 1, 2008. Tesla publicly opened their second showroom and service area in Menlo Park, California on July 22, 2008. The Menlo Park location is also the final assembly area for Tesla Roadsters. Tesla also operates service centers in New York City, Miami, Chicago, and Seattle. In 2007, Tesla announced plans to build additional service centers over the following few years to support sales of its next vehicle, the Model S sports sedan. This included an additional 15 service centers in United States major metropolitan locations. Possible locations for sales and service locations in Europe were announced in a letter to customers in May 2008. Recalls. As of May 2017, Tesla has issued two
