Cadillacs are known for comfort and style, not horsepower or speed. But with the 2013 Hennessey VR1200, that reputation changes. The mega-horsepower engine has a top speed of 242 MPH, and can reach speeds of 200 MPH in a very short and blurry mile.
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. Autoblog, 6 Sep 2012.
