There's a video at the link in which you can hear the OnStar rep calling the driver...On its way to doing the 1/4-mile in 11.07 seconds at 128 mph, a Hennessy-tuned 700-horsepower Cadillac CTS-V hit .99 longitudinal G as it left the start line. By the end of the run the phone inside the car was ringing, and it was your friendly neighborhood OnStar representative wondering "What ... do you think you're doing?" Ok, not quite... but they did have some questions.
