Watch the Hennessey Performance HPE850 Corvette ZR1 upgrade race a stock ZR1 to see how big a difference an extra 100 horsepower makes.
We love the 2019 Chevrolet Corvette ZR1. For almost half the price of a Lamborghini Huracan, you get a supercharged 755 hp monster that can keep up with the best cars on the road today. Zero to sixty is done in just 2.85 seconds with a top speed of 214 mph.
That’s fast. But you know what would be even faster? A Corvette with even more power.
That’s what Hennessey Performance is all about. They see a car that has less power than it could have, and then they tweak it to where it should be. They don’t ask questions about whether or not a car needs more power because the answer is always yes.
So they made the HPE850 upgrade for the ZR1. As the name implies, it has 850 horsepower thanks to several tweaks under the hood. Upgrades include new stainless steel headers, stainless steel midpipes, high flow catalytic converters, and a supercharger pulley upgrade. Combined, those tweaks provide an extra 95 horses, which is more than enough to show a stark difference on the drag strip.
Zero to sixty is shorted to just 2.6 seconds.
To show just how much the Corvette is improved, Hennessey lined up their HPE850 against a bone-stock ZR1 in drag and rolling races. The differences are expected, but still astounding.
From a dig, the HPE850 simply walks away. It grabs the early lead and the stock ZR1 just can’t do anything to keep up. This is hardly surprising given the fact the two cars are identical save for the HPE850’s additional power, but it’s still amazing to see.
The stock ZR1 fares a little better in the rolling race, but it still loses by several car lengths.
Hennessey also offers 1,000 and 1,200 horsepower upgrades for the ZR1, in case you wanted to start drag racing Koenigseggs or something. We’re not saying that’s more power than an RWD car can effectively use, but we’re not not saying it either.
