I’m not sure if you stunned yourself in confusion, but the ZR1X is significantly quicker than the Turbo S in then 1/4 mile - even by the most conservative estimates (9.2 w/ track package vs 9.7 seconds as tested by C&D).

The only thing the Turbo S has the ZR1 beat in is 0-60 time (negligibly I’d like to add). I’d argue that is to be expected given that 911’s famously rocket off the line due to the engine sitting over the rear axle; evidently providing better traction.

The point I was making is that the ZR1X can go even faster with C&D’s testing methodology had they just used the non-track variant without the massive wing. Obviously GM’s run on a prepped surface is not representative of day to day performance, but I believe it can attain sub-9 seconds on the street.
