Hennessey's 850 HP C7 Corvette Z06 Convertible Is An Absolute Animal

The forthcoming C8 Chevrolet Corvette Z06 promises to be an incredible performance car, but the C7 model still remains very impressive - and if it's been modified by Hennessey, even more so. The Texas tuner has been offering upgrade packages for the C7 Corvette Z06 for a number of years now in both HPE850 and HPE1000 guise. Both are utterly insane and this video of a Z06 Convertible with the HPE850 package being tested around Hennessey’s facility is sure to help get you through those mid-week blues.

For the HPE850 package, Hennessey upgrades the lower pulley, cylinder heads, valve springs, intake and exhaust valves, lifters and pushrods, and fits long-tube stainless steel headers, stainless steel midpipes, a high-flow air induction system, high-flow heat exchanger, custom camshaft, and high-flow catalytic converters. These changes result in 850 hp at 6,300 rpm and 715 lb-ft (969 Nm) of torque at 4,300 rpm. Hennessey says that the upgraded engine can send the car to 60 mph (96 km/h) in just 2.6 seconds and help it run down the quarter-mile in 10.3 seconds at 136 mph (219 km/h). The Corvette HPE650 tested in this video is equipped with an automatic transmission, although if we owned a C7 Z06, it would definitely be the six-speed manual variant. Nevertheless, listening to ii and watching it sprint from roughly 30 mph to over 130 mph in just a matter of seconds is seriously impressive. [embed]https://youtu.be/TmmONtfpGNI[/embed]
