Those wicked chaps at Hennessey Performance Engineering got their hands on a Cadillac CTS-Va and turned it into a real monster. Thanks to a V800 package that includes a twin-turbo system, external wastegates, blow-off valves, a high-performance fuel system with upgraded injectors and new engine management software, the 556 hp stock engine is now churning some 800hp and 780 lb-ft of torque. But for those that 800hp (anyone?) is too much, they’ve prepared more tuning packages (V600, V650, V700) that will cost less. A beast in disguise, Hennessey sure managed to get us dreaming of burning rubber from behind the wheel of their new 800hp CTS-V. How about you?
