Hennessey Performance, the Texan tuner capable of bolting a pair of turbochargers to virtually anything on four wheels, has come out with a new performance upgrade for the Cadillac CTS-V. This time the challenge for Hennessey founder John Hennessey and his team at the Lonestar Motorsports Park was to create a powerplant with Veyron-beating performance, and that they certainly have accomplished with the new VR1200 package.

A quick look at this dyno video reveals Hennessey's VR1200 package for the CTS-V delivers an incredible 1,066 horsepower to the rear wheels. According to Hennessey, that equates to an insane 1,226 horsepower and 1,109 pound-feet of torque at the flywheel.

To achieve these figures, Hennessey does away with the CTS-V's quite capable supercharged 6.2-liter V-8 and installs a new 7.0-liter unit. To this, a pair of turbochargers is bolted on, along with forged internals, high-flow cylinder heads and injectors, a custom camshaft, a new fuel system, dual wastegates, a full stainless steel exhaust system, new intakes, a custom engine management system and electronic boost controller.

The vehicle is fitted with a six-speed manual transmission as standard, though an automatic can be fitted after undergoing a special performance build and torque converter upgrade.

The end result, according to Hennessey's own estimates, is a 0-60 mph time of 2.9 seconds, a quarter mile ET of 10.2 seconds at 141 mph, and a top speed of 242 mph.

To go with the drivetrain mods, Hennessey also upgrades the brakes with new Brembos, adding huge 15.1-inch carbon ceramic discs with eight-piston calipers up front, and the same size discs but with six-piston calipers in the rear. These reside within 20-inch wheels shod with Michelin Pilot Super Sport tires.

The suspension also gets worked over, with new sway bars added front and rear, and the standard Magnetic Ride Control tuned by John Heinricy.

The final touch is the addition of a full carbon package, which adds a new front splitter, widened fenders, an integrated diffuser and a vented hood. Inside, owners can select to have most of the surfaces re-trimmed in carbon fiber and Alcantara.

Only 12 of these beasts will be built, each with their own serial-numbered dash and engine plaques.
