Cadillac CTS-V VR1200

 2013 Cadillac VR1200 Twin Turbo Coupe based on the two-door version of the CTS-V

There's a ton of stuff going on under the sheetmetal but the highlight of the tune can be found right behind Cadillac's crest.

Whereas the stock model features a 6.2-liter supercharged V8, Hennessey's version adopts a 7.0-liter twin-turbocharged V8 with an adjustable boost controller that allows the driver to select from three modes of power: 800HP, 1,000HP and if that's not enough, a tremendous 1,226HP (1,066WHP) and 1,109 lb-ft (1,502Nm) of torque.

In the highest setting, Hennessey says that the Cadillac VR1200 Twin Turbo Coupe is the "world's most powerful four-seat vehicle."

The tuning brand quotes a zero to 60mph (96km/h) time of 2.9 seconds, a quarter mile run in 10.2 seconds with an exit speed of 141mph (227km/h), and a top speed of…242mph (389km/h).

Other upgrades include a special clutch to handle the ferocious power of the twin-turbo V8, 20-inch wheels in 275/30YR tires at the front and 345/30YR at the rear, a suspension tune and a carbon fiber aero package.
