As the old saying goes, if power corrupts then absolute power corrupts absolutely. It may be a bit of a cliché, but it seems to be one John Hennessey lives by. The Texan created this 1,226-horsepower Cadillac CTS-V coupe at his Hennessey Performance shop, which more than doubles the already-competent base car's power output.
Called the VR1200 Twin Turbo Coupe, the car will be limited to just a dozen examples. It's based on a 2013 CTS-V Coupe but ditches the standard, supercharged 6.2-liter V8 for a 7.0-liter unit that breathes through a pair of ball-bearing turbochargers. There is also an air-to-water intercooler, and the engine is built to last thanks to forged aluminum pistons, forged steel connecting rods and crankshaft, and high-flowing cylinder heads. The entire rotating assembly is balanced and blueprinted as well.
The fuel system has also been heavily revised with heavy-duty fuel injectors and pumps. If you have to ask about the fuel economy, you just don't get it.
Instead, the key numbers include a claimed 242-mph top speed along with a 2.9-second sprint to 60mph from a standstill. The quarter-mile is dispatched in just 10.2 seconds, with a trap speed of 141mph. We bet the coupe is just some slicks away from breaking into the single digits.
All 1,226 horspower and 1,109lb-ft of power is routed to the 20x13-inch rear wheels through a six-speed manual, though Hennessey is happy to bolt a specially-built automatic into the car for an extra fee of $20,000. The rear tires are sized at an elephantine 345/30-20, while the fronts are 275/30-20s. For daily driving, the car can be switched to produce "just" 1,000 or 800 horsepower.
Putting a whoa on all that go are 15.1-inch Carbon Ceramic rotors all around squeezed by eight-piston calipers up front and six-pot units in the back. The suspension is lowered by one inch but retains GM's magnetic ride control dampers. They were specially tuned by GM test chief driver John Heinricy, however.
A three-year warranty is provided with the car too, for added peace of mind when driving what many would consider a tuner special. The price tag is equally impressive, at a whopping $295,000. Corruptive indeed.
