The Chevrolet Corvette has blossomed into a fine supercar, a serious one. Previously estimated to make around 625 horsepower, it has now been confirmed that its 6.2L supercharged V8 engine cranks out 650 horses.
Delving deeper, the no-nonsense LT4 V8 delivers 650 hp at 6,400 rpm and 650 lb-ft (881 Nm) of torque at 3,600 rpm, representing a 40 percent increase in peak torque (180 lb-ft / 244 Nm) over the previous Z06 and a 7.5 percent improvement over the C6 Corvette ZR1’s 604 lb-ft (819 Nm).
457 lb-ft (619 Nm) is produced just off idle, while 625 lb-ft (847 Nm) is achieved at only 2,800 rpm. The engine maintains 90 percent of peak torque (592 lb-ft / 802 Nm) from 2,500 to 5,400 rpm.
General Motors say the LT4′s impressive performance numbers are achieved with an engine that is nearly the same size as the very compact LT1 engine found in the regular Corvette Stingray. Its power density makes it one of the smallest and lightest 650-hp engines in the industry.
Considering how well-received the base C7 Corvette has been, we have no doubts the latest Corvette Z06 will have track performance deserving of a world-class supercar, one capable of going toe-to-toe with Europe’s best.
