2016 HPE1000 Twin Turbo Cadillac CTS-V

The latest CTS-V won’t be on sale until later this year, but Texas-based tuner, Hennessey Performance Engineering, is already planning to build the world’s fastest 4-door sedan based on it and it is calling it 2016 Hennessey HPE1000 Twin Turbo CTS-V. As if the stock 6.2L supercharged unit’s 640+ horsepower isn’t enough, Hennessey wants to push it to, as the model name suggest, 1,000 horsepower. And to achieve that, the outfit will ditch the mechanically-driven force induction unit in favour of twin turbo setup on a strengthened 6.2L V8 motor.

Expect the Hennessey-touched CTS-V to be loaded with performance upgrades including forged aluminum pistons, steel rods and crankshaft, custom HPE camshaft, upgraded fuel system and injector, carbon-ceramic brakes, bigger wheels and tires, wide body upgrade to accommodate wider tires, a mandatory custom interior – just to name a few. And what kind of performance you can expect from such monstrous power output? Company founder, John Hennessey believes that their take on the CTS-V will have a “top speed approaching 240 mph (about 386 kmh).”

If 1,000 ponies is a little excessive for you, you will be glad to know that HPE is also planning to offer other performance upgrades, which will include engine upgrade packages that deliver 750-800 hp, however, you should only opt for that if you prefer supercharger over turbos. No word on the pricing though, but brace yourself for something pretty traumatizing to your bank account.
