The latest ZR-1 with the new tire package is pretty much as fast as any other passenger car around a track. The data on these things is never 100% conclusive, but it suports these claims. Kit cars and race cars cant be counted in good conscience.
Motor trend hustled even the lowly z06/z07 around laguna sec faster than the mclaren and aventador. It will be exciting to see what the top c7s will do in the next few years.
Seriously, my car is small
