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.
Hennessy doesn’t have a running, driving vehicle to show for it at the moment, but announced today opening of the order form. So it shouldn’t be long before we see one breaking some type of law somewhere.
