Road & Track lined up the Corvette ZR1 next to the Corvette C6.R ALMS racing car to see how they'd compete in a straight line. Notice we didn't say "drag" or "drag race," since this isn't at the track and we can't tell the distance of the contest.

The C6.R is based on the ZR1, but comes in with about 500 horsepower to push its 2,745-pound weight and uses a sequential transmission and slicks. The ZR1 works with 638 horses but has 3,345 pounds to get going through a six-speed manual transmission and street tires.

The race starts at 0:15 seconds and ends at 0:23. You'll find the winner in the video after the jump.

      Wait... an entire post on a GM car without a single "Government Motors Sucks" in the comments? No way!

        I'm totally amazed... maybe we can get back to talking about cars for once... And it would be good to know the time and distance for the run, though I guess that since the pulls weren't at a track, they wouldn't be considered "official" anyway. And perhaps the ALMS team didn't want documented numbers published on their racer anyway...

      throw a few corners in that test, and the ZR1 would be beaten much worse... it's not just tires and sequential shifters- there's a lot of money and time put into that race car.

        ^ If there were corners the C6R's brakes and R comps would still be cold and it might actually not be an advantage.

      Sequential gearbox and less weight--no surprises here.

        Those didnt even matter. This was all tires.

          Sure, let me put slicks on my Fusion and I'll beat the ZR1. It's all tires derp!

          Agreed, its power to weight and tires. A sequential shifter alone doesn't lead to a gap like that at the finish

      At this point, it all comes down to the tires. The slicks on the C6.R are much more sticky, so they are able to put down much more horizontal force to the payment than the ZR1's road tires. This is despite the fact that the driver of the C6.R slams it and spins the tires while the ZR1 uses traction control to limit the power enough to maintain as much grip as its DOT rubber will allow. The power/weight ratio is actually slightly better with the ZR1, but power/weight is useless to any degree that it exceeds the friction coefficient of your rubber.

      The stickers add "down force" , accompanied by the wing makes the car sit lower. Its simple physics

      A purpose-built race car beat it's street-going (and emissions-legal) cousin? Who knew? Still, that was a few seconds well-spent.

      No surprise at all. But still a damn joy to watch and HEAR.

      I like how you couldn't even hear the ZR1. Damn.
