    Looks like the Corvette wins both by the time slips.

    Did you notice how bad Tesla Brakes are?

    No surprises here at all. The results are also meaningless. Drag races are won on how much torque one can put down to the pavement. The launch of the 'vette was also much better in the second run.

    Electric drive puts down maximum torque at a big 0 RPM, no IC engine can match that. However, electric motor torque also decays exponentially with rpm, whereas an IC engine can generate its maximum torque across a broad rpm band. This is evident towards the end of the 1/4 mile run where the Tesla acceleration is approaching 0 due to rapidly diminishing torque yet the 'vette is still exhibiting near constant acceleration due to near constant torque. Velocity being the time integral of acceleration (area under the acceleration v time curve) indicates that at the end of the 1/4 mile the Tesla is basically beginning to max out as it approaches very slowly its top end whereas the 'vette will still have time-linear increasing velocity.

    Sure a Tesla has enough HP to reach 130 mph top end, but it has no torque left to reach that speed in other than a very gentle fashion, and then only with considerable drain on the batteries as expending HP over time is the amount of energy depletion from the batteries. Consider a steady state legal cruising speed of 75 mph on a steep grade and you need to accelerate. Now which car would you rather have? In that scenario, a conventional IC vehicle with an equivalent HP to weight ratio would be the better choice due to the greater torque available.

    Impressive runs, should have switched lanes for second run. Mchicha I guessing going by your comment you have never dragged at your local track.

    If they had equal power/weight ratio, the torque wouldn't matter. That's what gears are for.

    Re: 2014 Corvette vs Tesla Model S

    Imagine the Telsa's electric motors working through a two-speed gearbox. If, at half track the Telsa could have shifted its motors to a more efficient operating speed, would it have been able to hold back the high speed charge of the Corvette? The Tesla Roadster was originally supposed to have such a gearbox, but they couldn't find anything that would package well that could also handle the high torque at idle. Given the advantage would mainly be at high speed, and given the fact that electric vehicles don't really do sustained very high speeds for very long, they ultimately just went with direct drive. Still, the Tesla must be darn near unbeatable in real world on-road situations. No delay, no waiting: just point and go.

    I posted similar drag racing events with an AMG Mercedes and a Viper that the Tesla smacked around easily. The torque of electric motors make them awesome for daily driving where you need it most.

    Was it just me or did the Tesla jump the light on the first run it "won?" Looked like it to me.

    I watched that 10 times. From the naked eye, looks like it should have been a red light.

    2nd run looks like the 'Vette driver controlled wheelspin on takeoff, thus the different outcome.

    Both times the Corvette had the fastest ET. Corvette is the fastest both times.

    Tesla is pretty impressive.
    6 speed transmissions are the future

    Understatement of the year. The Vette is a badass performer and the Tesla hangs right with it (actually faster in a typical street race) all the while weighing over 4000lbs. I have never heard a torque rating on the Tesla engines but I sure would like to know.

    Website says 400+ ft/lbs torque.
