Hennessey released details of a limited edition, 1,200hp version of the Cadillac CTS-V Sport Coupe today. Just twelve will be produced and each will feature upgrades to the engine, gearbox, suspension, braking system and aerodynamics, as well as a range of interior upgrades.
To start with the engine, Hennessey took the basic 6.2 liter V8 LSA engine out of the CTS-V Coupe and replaced it with a 427 CID aluminium V8. To this, forged aluminium pistons, steel connecting rods, steel crankshaft, ARP main studs and head bolts, high flow cylinder heads and a Hennessey VR1200 camshaft were added. The extra power comes from a twin turbocharger setup with an upgraded fuel system, upgraded injectors and dual wastegates.

The entire system gets engine management calibration, both dyno and road tests and exterior and interior badging. The engine features a three year, 36,000 mile limited warranty.
