Supercharged 2015 Corvette Z06 LT4 Rated at 650 Horsepower

After promising at least 625hp since it was shown to media in December of last year, Chevrolet has been tight-lipped regarding the actual power output of the supercharged 6.2L LT4 that lives under the carbon fiber hood of the 2015 Corvette Z06. Today, Corvette Chief Engineer Tadge Jeuchter announced at an SAE conference that the engine produces an SAE-certified 650hp at 6,400rpm and a peak of 650lb-ft of torque at 3,600rpm, a significant step up from the 460hp LT1 engine in the Stingray. In case you’ve forgotten, that’s more powerful than the SAE-certified 638hp from the LS9 in the previous range-topping C6 Corvette ZR1.
