The 2019 C7 ZR1, the fourth Corvette to carry the ZR1 badge, set a new standard for Chevrolet production vehicles with its supercharged 6.2L LT5 V8, producing an impressive 755 horsepower and 715 lb-ft of torque at the time.
Its aerodynamic features include wider fender flares, a carbon-fiber front splitter, a vented carbon-fiber “halo” hood, carbon-fiber rocker panel trim, and a carbon-fiber rear wing. For added performance, the optional ZTK Track Pack enhances aerodynamics with an adjustable high-wing rear spoiler, front splitter end caps, and a flat underbody, increasing downforce by 60%.
The LT5 engine, paired with an eight-speed automatic transmission and an electronic limited-slip differential, propels the ZR1 from 0-60 MPH in under 3 seconds, with a top speed exceeding 210 MPH. For those craving even more power, Hennessey Performance introduced the HPE1000 Package, boosting the LT5’s output to a staggering 1,000 horsepower and 966 lb-ft of torque.
One such example, offered on Bring A Trailer, is the first of a limited number of C7 ZR1s modified by Hennessey with the HPE1000 Package. Finished in Arctic White with a Jet Black leather interior, this car is equipped with the 3ZR Premium Equipment Group, Track Performance Package, carbon-ceramic brakes, Magnetic Ride Control, a removable carbon-fiber roof panel, power-adjustable heated and ventilated GT bucket seats, curb-view cameras, navigation, and a head-up display.
Hennessey’s modifications to the supercharged 6.2L LT5 V8 include a high-flow induction system, long-tube stainless steel exhaust headers, stainless steel mid-pipes, high-flow catalytic converters, custom engine management calibration, and upgraded valve springs, retainers, valves, lifters, and pushrods. These upgrades push the engine’s output to an extraordinary 1,000 horsepower and 966 lb-ft of torque, delivering extreme performance to an already formidable supercar.
