Just how quick is the Tesla Roadster now that it's been blessed with version 1.5 of its drivetrain? Pretty dang quick, as a recent 12.7-second blast down the quarter-mile will attest. The first powertrain that was installed in the electric car used a two-speed transmission, while the latest v1.5 needs just one speed for seamless power delivery from zero to the car's top speed. That should make the Roadster an excellent bracket car, especially considering it was able to put down such impressive numbers with a novice racer behind the wheel who posted a relatively poor .764 reaction time. Its terminal velocity was nearly 105 miles per hour, and whatever car happened to be in the lane next to the Tesla got its butt kicked by an electric car. What's this world coming to?

Some of us here at Autoblog team who've actually driven the Tesla Roadster, myself included, were surprised by this quick performance, but the proof comes courtesy of a scanned time slip from California's Infineon Raceway, which you can click at right to enlarge. Thanks for the tip, JP!
