The 2019 Corvette ZR1 was already a powerhouse, engineered to be the ultimate super-car iteration of the iconic Chevrolet Corvette.

A high-flow induction system, Hennessey lower pulley upgrade, custom camshaft, and ported cylinder heads are just some of the components that come together to unleash the full potential of the Corvette.

The valvetrain also receives a comprehensive upgrade, with new valves, valve springs, retainers, lifters, and pushrods contributing to improved efficiency and performance. The exhaust system, featuring long-tube stainless steel headers, stainless steel midpipes, and high-flow catalytic converters, ensures an exhilarating soundtrack to match the mind-boggling performance figures.

When the Hennessey 1000 HP C7 Corvette ZR1 roars to life, it unleashes an astounding 1,000 horsepower at 6,400 rpm and a jaw-dropping 966 pound-feet of torque at 4,400 rpm. This remarkable achievement represents a staggering increase of 245 horsepower and 251 pound-feet of torque compared to the already impressive stock setup.

To demonstrate the true prowess of their creation, Hennessey took the 1000 HP C7 Corvette ZR1 to Pennzoil Proving Grounds for a quick drive. With adrenaline-pumping acceleration and razor-sharp handling, this track beast showcased its capability to dominate any racecourse with ease.
