Hennessey Performance Engineering we keep this 2019 C7 Corvette ZR1 stock for long. But, ahead of its planned modifications, the tuning company is busy running baseline tests.
The latest video shows the American supercar beater sprinting from 0 to 194 mph and its a wonderful ode to the small-block V8 engine and the lovely noises it makes. It’s also utterly impressive to watch the speed climb with the accelerator planted to the floor as the eight-speed automatic transmission flips through gears with a snap. More good fun: the gas gauge begins to drop ever so slowly during the top-speed run.
HPE plans to offer even more power for the 755-horsepower Corvette ZR1 (though we know the car is making 654 hp at the rear wheels stock). For those with the need for speed, Hennessey will offer an HPE850, HPE1000 and HPE 1200 packages. The HPE850 package pushes power to, as one may surmise, 850 hp with a modified lower pulley, high flow cylinder heads, upgraded valve springs, intake and exhaust valves and new pushrods and lifters.
Moving to the HPE1000 package nets buyers an upgraded supercharger, but the HPE1200 package swaps out the standard 6.2-liter supercharged LT5 V8 engine for a 7.0-liter supercharged V8.
Have a look at the Corvette ZR1 going flat out right up above.
