The twin-turbo CTS-V Coupe is fitted with 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. The Cadillac is also fitted with a set of dual ball bearing turbochargers packs compressed atmosphere into the combustion chambers, assissted by high-flow cylinder heads.
Additional goodies include 15-inch carbon ceramic brakes, a fortified transmission, lowered suspension and Hennessey’s CarbonAero widebody kit. The turbos will boost torque to 950 lb-ft of torque at 4,000 rpm. Hennessey has stated the V1000 can accelerate from 0-62 mph in 3.5 seconds, with a top speed of 230 mph. It will run an outrageously impressive quarter mile time of 10.9 at 136 mph.
Only 12 of these cars will be built and the lucky buyers will also receive a one day track experience with retired General Motors test driver supreme John Heinricy.
