2015 Chevrolet Corvette Z06
It’s supercharged
Save your tears for the death of the naturally aspirated Z06. The new car uses a new 6.2-liter LT4 engine, complete with a small-displacement supercharger. The whole package is just one inch taller than the LT1 in the base Stingray, but it cranks out more than 625 hp and 635 lb-ft of torque. If you’re counting, that’s 120 more horsepower than the old LS7 and 30 more lb-ft of torque than what came from the supercharged LS9 in the mighty ZR1.
The blower is a 1.7-liter Eaton unit with shorter rotors than those found in the LS9’s supercharger, which helps the LT4 produce more power earlier in the rev range. Engineers also threw titanium valves, forged aluminum pistons, stainless steel exhaust headers, and Rotocast aluminum heads at the new mill.
