Hennessey Performance is teasing a brand new HPE700 upgrade for the McLaren 570GT.
We know Hennessey mostly from they’re work doing bonkers things to domestic muscle cars and pickup trucks. A six-wheel Ford Raptor with 600 horsepower? That’s Hennessey written all over it. A 1,000 horsepower Camaro to take on the Dodge Demon? Definitely Hennessey’s hallmark.
But upgrading a European supercar? That’s not something we normally see Hennessey dirty their hands with. However, the latest video posted on YouTube seems to indicate that Hennessey is set to work on the McLaren 570GT by giving it a 700 horsepower upgrade.
The video is titled “Hennessey McLaren 570GT with HPE700 Upgrade - Validation Testing,” which gives us a big clue as to what this is all about. Hennessey naming convention is to simply place the company acronym (HPE - Hennessey Performance Engineering) in front of the newly upgraded power figure, thus HPE700 means that this 570GT will receive 700 hp.
That’s a big boost from the stock versions 562 horses from its 3.8-L twin-turbo V8 engine. Normally, the 570GT takes around 3.3 seconds to rocket from zero to sixty miles per hour. The video teaser gives us a few seconds of watching the GT accelerate from zero, and through the magic of watching the YouTube timer clock upward as the speedo hits 60 mph, we can see that the GT certainly seems to get there faster than the stock version.
We don’t have specifics on just what Hennessey did to the McLaren in order to give it 700 horsepower, but Hennessey’s website has some older writing on what they’d planned to do: "twin turbo engine performance upgrades including upgraded twin turbo system, stainless steel exhaust upgrade, intercooler upgrades, lightweight wheel upgrades, and more."
Presumably, we are seeing each of these planned upgrades in action in the video above.
There’s no price or street date for Hennessey’s HPE700 McLaren 570GT, but they tend not to wait too long after releasing their teasers. Expect to hear more from them in the coming months.
