2019 Corvette ZR1 in Sebring, Orange
The Corvette ZR1 features an LT5 6.2L V-8 supercharged engine which dramatically advances the supercharging technologies first introduced in the 2009 sixth-generation Corvette ZR1 and continued with the 2015 seventh-generation Z06 Corvette. The engine, which is officially rated with an SAE-certified 755 horsepower (563 kW) and 715 lb-ft of torque (969Nm), establishes an entirely new benchmark in Chevrolet performance.
2009 Chevrolet Corvette ZR1
The ZR-1 returned with the 1990 Corvette lineup after an eighteen year hiatus.  This time, it featured a special LT5 engine that had been developed by Lotus (which, at the time, had been a subsidiary of General Motors.) The LT5 engine featured an all-aluminum block, four overhead camshafts, and 32 valves. It also featured an air management system which enabled the car to maintain proper operation while closing off half of its fuel injection system.
