Imagine a lighter-weight Cadillac CTS-V Coupe with nearly double the horsepower, a wider stance and panhandle-sized contact patches.That's the Hennessey V1000, a model the company plans to build only 12 copies of for well-to-do speed freaks.

That's 1,000 hp at 6,400 rpm out of a twin-turbocharged 427ci LS V8 (sounds like it's the LS7). The turbines will boost torque to 950 lb-ft torque at 4,000 rpm, which will make getting the power to the pavement a matter of some intrigue. Hennessey projects the car will hook up enough to get from 0-60 in 3.5 seconds, but top out at 230 mph. Quarter mile? 10.9 @ 136 mph. Yeah, that's kind of a smoker.

The upgrade also involves lots of work, to the top and bottom of the GM V8, along with a clutch (or torque converter) upgrade, 15.1" Brembo carbon ceramic brakes front and rear (8-piston calipers front, 6-piston rear), with Hennessey monoblock wheels and huge Michelin Pilot Super Sport tires.

John Hennessey told us the company's "GT3 RS" treatment of the Cadillac V coupe might yield weight savings of up to 200 lbs, with the widebody kit made from carbon fiber and optional lighter seats (and a rear seat delete option).
