Hennessey announces 1,000-hp Cadillac CTS-V

Called HPE1000, Hennessey\'s tuned CTS-V will be able to hit a top speed of 240 mph.

American tuner Hennessey has announced plans to offer a tuning package for the new 2016 Cadillac CTS-V that will bump the sedan's power output to roughly 1,000 horsepower.

Quietly aimed at the Dodge Charger Hellcat, Hennessey's HPE1000 is billed as the world's fastest four-door sedan. It is powered by a heavily-modified version of the stock CTS-V's 6.2-liter V8 engine that gains forged aluminum pistons, a new crankshaft, ported cylinder heads and a pair of beefy turbochargers that replace the factory supercharger.

With about 1,000 ponies under the hood - 360 more than stock - the CTS-V can reach a top speed of roughly 240 mph if it is given enough tarmac. An electronic boost controller keeps the turbos in check, while K&N air filters and a stainless steel sport exhaust system help the engine breath.

Visually, the HPE1000 stands out from the stock CTS-V thanks to a much lower ride height, a more aggressive front bumper that gains a splitter, a sprinkling of gloss black trim on both ends and sizable fender flares. The sedan rides on upsized alloy wheels wrapped by low-profile tires.

Hennessey will build just 24 examples of the modified Cadillac CTS-V for the 2016 model year, but how much each one will cost was not revealed. The tuner will also offer a less extreme package that pushes the eight-cylinder's output to anywhere between 750 and 800 horsepower while retaining the supercharger.
