If you thought Hennessey wasn’t planning an even hotter version of the all-new Cadillac CTS-V, you must not have your head screwed on straight. The master of all things speed, Hennessey just unveiled an early concept of its upcoming 1,000-horsepower Cadillac CTS-V. And it sounds bonkers.

The Hennessey CTS-V gets slightly more aggressive on the outside with a minor revision to the front fascia, some new wheels, a wide body kit to match the wider stance, and a lower center of gravity. Just like the factory fresh 640-horsepower CTS-V, the exterior doesn’t need much in terms of aggressive styling—it’s under the hood that counts.

From the bottom-up, Hennessey will offer three different versions of its CTS-V super-sedan. The HPE750 will be the base, putting to use a pulley upgrade, a high-flow air induction system, new catalytic converters, an upgraded ECU, and a total output of 750 horsepower. Not too shabby.

Move up from there, and the HPE800 will get you to 800 horsepower via high-flow cylinder heads, an intercooler heat exchanger upgrade, and a custom camshaft. All these modifications sitting on top of GM’s already potent 6.2-liter supercharged V8.

But the HPE1000 upgrade is where things really start to get interesting. An even larger, 2.9-liter supercharger is affixed to the upgrades already mentioned, along with a revised ECU, ported cylinder heads, and a new fuel system. When it’s all said and done, the crazy caddy will push out 1,000 horsepower at 6,300 rpm.
