New Chevrolet Corvette ZR1 goes big on power with over 1,000 hp from its twin turbo V8. Capable of pounding out a sub-10-second quarter mile, and going over 215 mph, this is not your average Corvette, this is a supercar beating Corvette. The 5.5L twin turbo LT7 V8 engine produces 1,064 hp and 828 lb-ft of torque in what is a huge 309 hp increase over the previous generation ZR1 . No hybrid systems or any electrification here folks, just good old fashioned V8 power with some forced induction assistance.
