This is a full lap of the CTS-V at Road America to give you a better idea of the sheer speed it's capable of. I did brake early a few times, simply because it's not my car.
You'll also note the excellent overlay that shows data for speed, throttle and brake input, steering angle, and more. That's the Performance Data Recorder that comes as an option on both the CTS-V and the Corvette. It's truly fantastic; look for more on that in the future. Enjoy.
