At the heart of tuned Cadillacs is GM's new 6.2L LSA supercharged V8, which in standard trim already outputs a healthy 556hp (414kW). Add a K&N sports air filter, upgraded supercharger pulley and belt, and revised ECU, and the powerplant churns out 610hp (455kW) and 605lb-ft (820Nm) of torque for the basic V600 package. Hennessey claims a 0-60mph time of just 3.7 seconds, an 11.8 second quarter mile ET and a top speed of 195mph.
Next in line is a series of upgrades delivering 650hp (485kW) and 700hp, respectively. Additional modifications necessary for the power hike includes a new cold air induction system, new camshafts, stainless steel headers and a full 3in exhaust, and an intercooler upgrades. Expect to see the 0-60mph time drop to around 3.1 seconds when fitted with these upgrades plus 20in wheels shod with Nitto drag radial tires.
Rounding out the range is the V800 twin-turbo upgrade delivering a supercar-rivalling 800hp (595kW) and 780lb-ft (1,056Nm) of torque. Some of the extra modifications include a custom twin-turbo set-up with external wastegates, blow-off-valves and a fuel delivery system upgrade.
