IndyCar driver J.R. Hildebrand and Formula D drifter Tyler McQuarrie are no strangers to the Long Beach street circuit. What happens when the Cadillac tuners at D3 give them almost 1,500 horsepower's worth of CTS-V Coupes and let them loose?

As it turns out, there's a lot of supercharger whine and a lot of tire smoke. And if you thought those drivers had cojones, they had absolutely nothing on the rodeo clown of a cameraman filmed by a guy with a camera who happened to drive by.
