There are a handful of vehicles on this blue Earth that can warp one's perception of speed. The Cadillac CTS-V holds a seat at that table of chieftains thanks to its brawny supercharged V8 engine. Now it looks as if the cats at Hennessey have decided to wring even more power from black sheep of the Crest's stable.

The 2013 VR1200 Twin Turbo Coupe ditches the stock block and blower for a 7.0-liter lump and a pair of turbos. With innards like forged pistons, connecting rods and a forged crankshaft, the engine is good for 1,226 horsepower and 1,109 pound-feet of torque at the flywheel. The company says the finished product is basically a de-tuned version of the same beating heart that powers the Venom GT.

Hennessey also swapped the stock brakes for 15.1-inch carbon ceramic rotors front and rear pressed by eight-piston clamps at the bow and six-piston calipers on the stern. A slew of carbon fiber widebody pieces outside and a magnetic ride suspension tuned by none other than John Heinricy himself are just a few of the other upgrades.

What's the point of such a machine? Hennessey wants the VR1200 to be able to do 200 miles per hour in the standing mile. With a top speed of 242 mph, the two-door easily eclipses the stock CTS-V's 180 mph v-max. Check out the car's dyno run in the video below, and head over to Hennessey for more information. If you like what you see, you better get on the phone. The company only plans to build 12 examples.
