We all know just how awesome the 640-horsepower 2016 CTS-V is, but there is still plenty of untapped potential there. Getting the fast sedan up to 700 or 800 horses shouldn’t be an issue at all, but that’s not good enough for the folks at Hennessey. Nope, the famed tuning company wanted more, so it pushed the boundaries and managed to inject up to 1,000 horsepower into the Caddy.
Known as the HPE1000 tuning kit, the key components that Hennessey tossed into the CTS-V include forged aluminum pistons, forged steel connecting rods and crankshaft, twin ball-bearing turbos in place of the factory supercharger, a custom camshaft, upgraded fuel injectors, an air-to-air intercooler, a stainless-steel exhaust system, and more. To prevent transmission damage, the Hennessy team will also upgrade the transmission to handle the extra grunt.
This all adds up to an insane 1,000 horsepower at 6,500 rpm. Unfortunately, Hennessey did not release the torque numbers, but I would guess that it is north of 700 pound-feet. Though testing is still underway and not all of the performance numbers are available, initial tests indicate that the CTS-V HPE1000 will top out at around 240 mph. In fact, the team got it up to 221 mph before running out of road.
As with all HPE packages, there are also a few options buyers can add in. These include carbon-ceramic brakes, a wide-body kit, larger wheels and tires, and upgraded interior bits.
Hennessey is also working on two less-insane kits for the CTS-V, including the 750-horse HPE750 and the 800-horsepower HPE800.
There are no pricing details yet, but Hennessey should release them soon, so stay tuned.
