Hennessey’s 1200-hp Corvette ZR1 is taken for a few laps around the Pennzoil Proving Grounds and wow is this car a beast!
The C7 ZR1 stands as the pinnacle of Corvette performance with its exclusive LT5 engine that produces a stock 755-horsepower and 715 lb-ft of torque. Once the pros at HP Tuners were able to come up with work-around to the encrypted ECU, tuners like Hennessey were able to fully unlock the engine’s potential and custom tune the supercharged V8.
The HPE1200 package adds custom heads, camshaft, and a ported factory supercharger among is upgrades and even the 8-speed auto transmission was beefed up to handle the additional power. Hennessey’s website does warn that the HPE1200 ZR1 requires race gas.
But that’s the kind of thing you need to do if you want to be hittings the 8s in the quarter-mile. The Sebring Orange ZR1 coupe was seen in the video running the quarter-mile in 8.975 seconds at 156.25 mph. We also see another timed run where the Corvette runs to over 150 mph from a standing start.
