Hennessey Cadillac CTS-V



John Hennessey is not a man known for restraint. The owner of the eponymous Texas-based speed shop crams hundreds of surplus horses into the drivelines of everything he touches, whether it’s pickup trucks, aHellcat-chasing 717-hp Mustang, or a menacing Jaguar F-type. Now, he’s promising to tune up the 2016 Cadillac CTS-V with a tidy half-ton of horses.



Hennessey will offer three packages for the upcoming CTS-V. The first adds 110 new friends to the Caddy’s 640-horse stable, thanks to new supercharger pulleys, new cylinder heads, a custom cam, an intercooler, and the like. A midrange package offers 800 horsepower, and both of those packages come with a three-year/36,000-mile warranty, along with “premium floor mats,”.


But if you’re really unsatisfied with the rocket Caddy’s stock offerings, you’ll want to open your wallet all the way and opt for the HPE1000 package. This baby ditches the supercharger for twin turbos and brings along brand-new everything: Aluminum pistons, a forged steel crank and rods, upgraded cylinder heads, and a beefed-up fuel system are just the start of things, and all the requisite tuning and fettling is included. At the half-ton horsepower level, Hennessey offers only a one-year/12,000-mile warranty, and it says ominously that transmission upgrades are “required.”
