This second generation and much improved version of the Cadillac CTS-V sports sedan, comes with an engine derived from the Corvette ZR1, no less. The supercharged 6.2L V8 has a net output of 550 hp with 550 lb-ft of torque. This should be sufficient for up to 180 mph perhaps even more, making this car the most powerful and fastest ever built by Cadillac. For the price (approx. $62K in the USA) this will be one of the best values for this type of car. This is one car I would seriously consider buying.
