Last year, we sampled Hennessey’s 700 horsepower version of the Cadillac CTS-V, and quite frankly, it frightened us. As Jonny Lieberman said at the time, “we simply weren’t prepared for the fury of the V700.”

Of course, adding a little under 150 horsepower to the CTS-V is just getting started for Hennessey. The Texas tuner has just released a preview of its upcoming Twin-Turbo CTS-V Coupe model packing no less than 1,000 horsepower. The heart of the car is a 427 cubic-inch LS V8 featuring upgraded internals like forged low compression pistons, forged steel connecting rods, forged steel crank and ARP main studs and head bolts. A set of dual ball bearing turbochargers packs atmosphere into the combustion chambers, assisted by high-flow cylinder heads. Additional upgrades include items like 15-inch carbon ceramic brakes, a fortified transmission, lowered suspension and Hennessey’s CarbonAero widebody kit. As a bonus, buyers will also receive a one day track experience with retired General Motors test driver supreme John Heinricy.

Hennessey plans to build just 12 of the V1000 Twin-Turbos, and pricing has not yet been released. You can view the full list of V1000 features and upgrades after the jump.
