We wouldn't blame you if you threw a skeptical eye on the 2010 Cadillac CTS-V Hennessey V700 power claims. After all, more than 700 horsepower at the crank is hefty chunk of grunt, even from a supercharged small block. Fortunately, John Hennessey has been kind enough to allow the kids at Inside Line to stick his four-door beastie on the rollers for all to see. How'd it do?

The big-bad Cadillac put down 636 horsepower and 656 lb-ft of torque. Run those figures through the time-tested 15-percent driveline loss, and Hennessey's claims of world-dominating horsepower seem pretty close to the mark. No wonder the breathed-on Caddy is so good at obliterating its tires. Click past the jump for a video of the fire-breathing action.
