Hennessey Says New Cadillac CTS-V VR1200 Twin Turbo Coupe is the World's Most Powerful 4-Seater

| |

Not the one to shy away from the insane horsepower wars of our time, Hennessey Performance is lifting the bar for tuners with the presentation of the new 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.

More details on the tune can be found in the list that follows below.
