Won't see similar performance out of the C8 because there is no way it will only weigh 1 ton like that car does. Odds are it will end up at 3300+ poounds.

It seems that apparently I was not so wrong at all, or at least in the LT1 version with the 0-60 in 3 seconds (versus the C8 Z51 under 3 seconds), although now you have to see the rest
