Hennessey’s upgraded C7 Corvette ZR1, now packing 1,000 horsepower
The C7 Chevrolet Corvette ZR1 was already an engineering marvel at launch, boasting 755 horsepower from its 6.2-liter supercharged V8. Now, thanks to Hennessey Performance’s HPE1000 package, this American icon has been transformed into a true powerhouse, delivering a staggering 1,000 horsepower and 966 lb-ft of torque. One such example, a meticulously maintained 2019 model, is currently up for auction, offering enthusiasts a chance to own a hypercar-level machine at a fraction of the cost.
Hennessey’s enhancements to the ZR1 include high-performance upgrades such as new valve springs, lifters, retainers, pushrods, a high-flow air intake, long tube stainless steel headers, high-flow catalytic converters, and a revised lower supercharger pulley. These modifications, paired with a finely tuned ECU, unleash the ZR1’s full potential, making it one of the most potent street-legal Corvettes ever built.
This Arctic White ZR1, modified in 2023, retains a factory-fresh appearance with minimal exterior changes, save for Hennessey badging. It’s equipped with Chevrolet’s optional ZTK Track Performance Package, which includes an adjustable rear wing, a prominent front splitter, and aerodynamic enhancements designed for track domination. Michelin Pilot Sport Cup 2 tires wrap the original 19-inch front and 20-inch rear wheels, ensuring the car’s grip matches its brute force.
Inside, this ZR1 remains true to its roots, blending comfort with race-inspired aesthetics. Paired with an eight-speed automatic transmission, the car channels its immense power to the rear wheels, delivering breathtaking acceleration and top-tier handling.
Having been driven just 5,000 miles (8,000 km), this C7 ZR1 is in near-new condition, promising years of performance thrills. For collectors and speed enthusiasts, this Hennessey-tuned Corvette represents an exceptional opportunity to own a supercar with hypercar performance at an attainable price point.
