Marvel At Hennessey’s 850 HP C7 Corvette Z06 Showing Off

If you happen to own a C7 Chevrolet Corvette Z06 or plan on buying one, Hennessey has just released an upgrade package that promises to lift the sports car to new heights.

Dubbed the HPE850, the package sees a handful of modifications made to the Z06’s 6.2-liter supercharged V8 engine, which ordinarily produces 650 hp at 6,400 rpm and 650 lb-ft (881 Nm) at 3,600 rpm, and lifts it up to 850 hp and 715 lb-ft (969 Nm).

Hennessey has been able to make these gains thanks to upgraded cylinder heads, valve springs, camshafts, intake system, and exhaust. It also tweaks with the ECU to ensure the car runs just as it should and doesn’t suffer from any reliability issues that could be caused by the horsepower and torque gains.

The Texas tuner says that a Corvette Z06 equipped with the HPE850 package is capable of hitting 60 mph (96 km/h) in a mere 2.6 seconds while also being able to sprint down the quarter-mile in just 10.3 seconds at 136 mph (219 km/h).

With the exception of some badges, few visual changes have been made to the car, meaning you’ll be able to shock other Z06s, plus lots of exotics, on the street with this Vette’s performance.

Finally, this is going to be a limited run, as Hennessey plans on just offering 100 examples of its HPE850 upgrade package to customers.

How Does The 495 HP 2020 Corvette Fare Against A 760 HP Mustang Shelby GT500?

Whenever a performance-focused vehicle is released in the U.S, you can be assured that Hennessey Performance will get its hands on one and bump up its performance. However, before working on a recent C8 Corvette and Ford Mustang Shelby GT500 that came into its shop, the tuner lined up the two to see how they compare in a straight-line.

Kicking things off is a drag race from a standing start where the Corvette has an advantage. You see, while the ‘Vette’s 6.2-liter naturally-aspirated V8 engine ‘only’ churns out 495 hp with the Z51 Performance Package, it is mid-engined and has much better grip than the GT500.

Consequently, the Corvette gets off the line for quicker than the Mustang which, by the way, uses a 5.2-liter supercharged V8 with no less than 760 hp. The Chevy holds on to its lead for quite a long time and it isn’t until the C8 hits roughly 120 mph (193 km/h) that the Mustang overtakes it and storms ahead thanks to its added power.

For the second test, the two went toe-to-toe in a rolling drag race from 40 mph (64 km/h). This race favors the Mustang because it is able to put all of its power to the ground from the get-go without encountering any traction issues like it does when getting off the line.

Neither of these results are surprising but they have made us very intrigued to see how Hennessey’s twin-turbo Corvette will stack up against a GT500 when it’s been tuned and is running at full power.
