From the company that brought you Steven Tyler's 1,200hp Venom GT Spyder and the 805hp twin-turbo Jeep Grand Cherokee, we present to you the custom monster known as the 2013 VR1200 Twin Turbo Coupe. It is based on the Cadillac CTS, and only 12 of these Hennessey Performance masterpieces will be made. It's got 1,066 rear-wheel horsepower (1,226 bhp total), and 964 lb-ft of rear-wheel torque (1,109 total). Those numbers from the 7.0-liter twin-turbo V8 equate to a 0-60 time of 2.9 seconds and a top speed of 242 mph. And to think we believed the CTS-V was quick. Below is a total list of upgrades, and to the right are 20 beautiful pictures of this gorgeous machine.
