This was a 2018 CTS-V. It was pretty fun, duh, but I wondered how hard it would be to drive on actual streets.
We had the nannies turned to Track II most of the time, for one event they had them all off and we tried to drift on a wet parking lot area. It was fun to accelerate from a stop, you had to hammer the brake pedal HARD and floor the accelerator at the same time, until you lifted off the brakes and the car would shudder and chirp and go.
640 horsepower. We also drove the ATS V at the same event and it struck me as being more of a daily car, not nearly so crazy.
