GM announced horsepower and torque ratings for the new LT4-powered Corvette Z06, and damn are they impressive. The 2015 Corvette Z06's 6.2-liter supercharged V-8 makes an astonishing 650 hp and 650 lb-ft of torque, making it one of the most powerful cars on the market today, and the most powerful Chevrolet ever built.

Enjoy - screw the image problem - you can get either an 8 speed auto or a seven speed MANUAL!  The only other cars with this much power to offer a manual are the Shelby GT500 and the Viper.
