It offered a new battery pack with cells from LG Chem[31] increasing capacity by 50% to 70 kWh, a new aero kit designed to reduce drag, and new tires with lower rolling resistance.

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.

The Final Edition Roadster did not have any performance modifications, but featured sporting atomic red paint, a duo of dark silver stripes on its hood and rear clamshell, and exclusive anthracite aluminum wheels.

[100][101] 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).

[110] Scotty Pollacheck, a high-performance driver for Killacycle, drove a 2010 Tesla Roadster Sport at the Wayland Invitational Drag Race in Portland, Oregon, in July 2009.

It can be recharged with AC using:[132] Charging times vary depending on the ESS's state-of-charge, the available voltage, and the available circuit breaker amp rating (current).

[141][158] As the Roadster does not use gasoline, petroleum efficiency (MPG, L/100 km) cannot be measured directly but instead is calculated using one of several equivalent methods: A number comparable to the typical Monroney sticker's "pump-to-wheel" fuel efficiency can be calculated based on regulations from the DOE and its energy content for a U.S. gallon of gasoline of 33,705 Wh⁄gal (also called the Lower Heating Value (LHV) of gasoline):[159][160] For CAFE regulatory purposes, the DOE's full petroleum-equivalency equation combines the primary energy efficiencies of the US electric grid and the well-to-pump path with a "fuel content factor" that quantifies the value of conservation, scarcity of fuels, and energy security in the US.

[164] 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.

[citation needed] 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.

Using wording from the National Highway Traffic and Safety Administration, Tesla told customers that without this adjustment, the driver could lose control of the car.

The recall followed an incident where the low voltage auxiliary cable in a vehicle chafed against the edge of a carbon fiber panel, causing a short, smoke and a possible fire behind the right front headlamp.

[173] In the March 2010 print edition of British enthusiast magazine EVO (p. 120), editor Richard Meaden was the first to review the all-new right-hand-drive version of the Roadster.

Away from traffic lights you'd murder anything, be it a 911 Turbo, GT-R or 599, simply because while they have to mess about with balancing revs and clutch, or fiddle with launch controls and invalid warranties, all you have to do is floor the throttle and wave goodbye".

In December 2009, The Wall Street Journal editor Joseph White conducted an extended test-drive and determined that "you can have enormous fun within the legal speed limit as you whoosh around unsuspecting Camry drivers, zapping from 40 to 60 miles per hour in two seconds while the startled victims eat your electric dust".

[175] In November 2009, Automobile Magazine West Coast editor Jason Cammisa spent a week driving a production Tesla Roadster.

It's like driving a Lamborghini with a big V-12 revved over 6000 rpm at all times, waiting to pounce—without the noise, vibration, or misdemeanor arrest for disturbing the peace".

Despite the flat-out sprints, the drag racing, the donuts, the top-speed runs, and dicing through traffic like there's a jet pack strapped to the trunk, Pacific Gas and Electric—which generated power for the Tesla—released into the atmosphere the same amount of carbon dioxide as would a gasoline-powered car getting 99 mpg.

[177] In May 2009, Car and Driver technical editor Aaron Robinson wrote a review based on the first extended test-drive of a production Tesla Roadster.

[178] In February 2009, automotive critic Dan Neil of the Los Angeles Times called the production Tesla Roadster "a superb piece of machinery: stiff, well sorted, highly focused, dead-sexy and eerily quick".

Engineering editor Dennis Simanitis said the testing confirmed what he called "extravagant claims", that the Roadster had a 4.0 s 0 to 60 mph (0 to 97 km/h) acceleration and a 200-mile (320 km) range.

[180] Testing a pre-production car in early 2008, Road & Track said "The Tesla feels composed and competent at speed with great turn-in and transitioning response", though they recommended against it as a "primary grocery-getter".

[184] In a November 27, 2006, review of a prototype Roadster in Slate, Paul Boutin wrote, "A week ago, I went for a spin in the fastest, most fun car I've ever ridden in—and that includes the Aston Martin I tried to buy once.

[185] In the third quarter of 2008, Top Gear's Jeremy Clarkson reviewed two production Roadsters with the v1.5 transmission and described the driving experience with the exclamations "God Almighty!

[188] Tesla spokesperson responded with statements in blogs and to mainstream news organizations that the cars provided to Top Gear never had less than 20% charge and never experienced brake failure.

[191][189] After numerous blogs and several large news organizations began following the controversy,[192] the BBC issued a statement saying "the tested Tesla was filmed being pushed into the shed in order to show what would happen if the Roadster had run out of charge.

[193] After several weeks of increasing pressure and inquiries from the BBC, Clarkson wrote a blog entry for The Times, acknowledging that "Inevitably, the film we had shot was a bit of a mess.

[9] Tesla's US exemption for not having special two-stage passenger airbags expired for cars made after the end of 2011 so the last Roadsters were not sold in the American market for regulatory reasons.

[209] Kevin Yu, the director of Tesla Motors Asia Pacific, said Roadsters in Japan had additional yearly taxes for exceeding the width limit of normal sized cars.

[212]The world distance record of 501 km (311 mi) for a production electric car on a single charge was set by a Roadster on October 27, 2009, during the Global Green Challenge in outback Australia, in which it averaged a speed of 25 mph (40 km/h).

[215] In December 2017, Elon Musk announced that his personal Tesla Roadster, sn:686, would be launched into space, serving as dummy payload on the maiden flight of the SpaceX Falcon Heavy rocket.
