Some good runs here with a lot of C6 ZR1 action. Yes, we all want to see tuned C7 ZR1's take on tuned McLaren 570's but the C6 is no slouch. The camera car in the first set of runs is a 700 horsepower C6 ZR1.

It goes up against a strong heads/cam 2nd Gen CTS-V first and the CTS-V must have more than it is letting on. It pulls strongly.

A 650 hp C6 ZR1 pulls the 700 hp ZR1 camera car next and perhaps the passenger weight is to blame.

A Paxton Mustang GT Coyote tries its luck but is smoked.

Now the bolt on McLaren 570S. Surprisingly, it can not hang with the camera car.

There is a 3-way with an even strong 850 horsepower C6 ZR1 and it demolishes both cars but the McLaren 570S again trails both ZR1's significantly.

A twin turbo Coyote Mustang GT takes over as the camera car. It's quite stout blowing the McLaren 570S away.

The Paxton Mustang is not even a race.

Finally a supercharged C6 Z06 takes over as the camera car. It first runs the 650 horsepower C6 ZR1 which pulls it.

It tries the even stronger 850 horsepower ZR1 next. There are some shifting issues but the ZR1 takes it.

Finally there are some runs between the McLaren and the Paxton Mustang which are close with the McLaren edging. It sure seems to be a slow 570S for supposedly a tune and downpipe.
