The 2019 Chevrolet Corvette ZR1 has 755 horsepower and 715 pound-feet of torque, all thanks to specially-developed V8 engine.

Not every single generation of the Chevrolet Corvette has received a hardcore ZR1 variant. In fact, the latest is the fourth ZR1 model in seven generations, proving just how special it is. And if you have been following the sports car’s debut, you’ll know the LT5 engine powering the ZR1 is the most powerful engine ever put in a production car by GM.

But where did all that power come from? Speaking to Automotive News, chief engineer of the LT5, Jordan Lee, shared some details on the engine. At its core, the LT5’s architecture is the same as the LT4, sharing the same block, head, pistons, and connecting rods. The additional performance comes from an all-new supercharger, an all-new throttle body, a dual fuel system, two enginecontrollers to control the fuel system, modifications to the lube system, a different crankshaftmaterial made of higher-strength alloy, and a shaker hood.
