The Tesla Roadster is an all-electric battery-powered four-seater sports car prototype from Tesla, Inc. Tesla has said it will be capable of 0 to 60 mph (0 to 97 km/h) in 1.9 seconds, quicker than any street legal production car to date at its announcement in November 2017. The Roadster is the successor to Tesla's first production car, which was the 2008 Roadster.
Tesla said they will begin selling the car in 2020, though not before the Tesla Model Y goes on sale. Elon Musk said that the Roadster would have a new acceleration mode that is quicker than the acceleration available with the Tesla Model S and X.

Overview
History
In 2011, at the end of the production run of the original Tesla Roadster, Elon Musk suggested that a new version of the Roadster, without the Lotus chassis, would return to production by 2014. The new Roadster was first teased in 2014.
In 2015, Musk suggested a new Roadster in 2019, capable of faster acceleration. A tweet by Elon Musk in December 2016 reconfirmed a second Roadster was in the works, but still "some years away". The second Roadster was designed by Franz von Holzhausen.
The 2020 version of the Roadster was shown as a surprise at the end of the Tesla Semi event on November 16, 2017--during which a Roadster was driven out of the back of one of the semi-truck trailers to the song "Sabotage". Musk explained the concept as: "The point of doing this is to give a hardcore smackdown to gasoline cars. Driving a gasoline sports car is going to feel like a steam engine with a side of quiche." The car will retail for upward of $200,000; test rides were given at the event for those who immediately paid the first $5,000 of a $50,000 deposit to pre-order the vehicle. Additional information followed after the teaser, such as the various world-record speeds Tesla said it will break.
Pre-order marketing
As of 2017, pre-orders of the Roadster had begun, with a US $50,000 deposit required. Tesla owners taking part in the referral promotion program began accumulating discounts toward the purchase of a Roadster based on the number of referrals. Those reaching 55 confirmed referrals obtained a 100% rebate toward a future Roadster purchase.
Price
The base model was expected to sell for US $200,000 but the first 1,000 to be produced, the so-called Founder's Series, will be priced at $250,000. Full payment would be required to pre-order the latter vehicle. Deposits for the Roadster should help Tesla cover some of their 2018 capital expenditures.

Design
The second generation Tesla Roadster is a 2+2 roadster with a removable glass roof. It was designed by Franz von Holzhausen, formerly of Mazda. The Roadster has a 2+2 seating arrangements, with smaller rear seats for two passengers.
The Roadster has three electric motors, one in front and two at the rear, allowing for all-wheel drive, and torque vectoring during cornering. Tesla said that the vehicle had a 200 kWh (720 MJ) battery, twice the capacity of the Tesla Model S P100D, and giving a 621 miles (1,000 km) range on one charge at highway speeds. Tesla stated that the torque at wheels was 10,000 N?m (7,400 lb?ft). The rear wheels are larger than the front wheels.
Performance estimates
At the November 17, 2017 unveiling, Tesla said the Roadster's acceleration will be:
- 0-97 km/h (0-60 mph) in 1.9 seconds
- 0-161 km/h (0-100 mph) in 4.2 seconds
They said the 0 to 1/4 mi (0.0 to 0.4 km) time will be 8.9 seconds, with a top speed above 400 km/h (250 mph). If the production Roadster achieves these performance numbers, it will outperform the supercars of 2017 and would set new production car records, none of which had yet done better than 0-100 km/h (0-62 mph) in 2.0 seconds or 9.0 seconds in the 1/4 mile. The quickest 0-60 time of a 2017 production street legal car is set by the Dodge Challenger SRT Demon, doing that in 2.3 seconds.
Independent analyses
Research completed by Bloomberg L.P. indicates that the estimate as to range per charge is optimistic, based on comments from Salim Morsy, electric vehicle analyst at Bloomberg New Energy Finance. In an article titled Tesla's Newest Promises Break the Laws of Batteries, Morsey indicated that the claimed battery capacity would require batteries that would be too large for the Roadster's small frame. "I really don't think the car you saw last week had the full 200 kilowatt hours in it. I don't think it's physically possible to do that right now."
Venkat Viswanathan, described as a "mechanical engineering assistant professor who works at the Wilton E. Scott Institute for Energy Innovation and focuses on next-generation battery technology" told Jalopnik (a Gizmodo Media Group publication) that the 1.9 second figure for 0 to 60 mph seems reasonable in spite of the estimated battery weight of 833 kg or 1,836 pounds. He added that the feasibility of the acceleration claim assumed that suitable tires would be available for the maximum traction that will be required. Viswanathan did not address the issue of the claimed range with current battery technology.
