McLaren 720S Stood No Chance Against Hennessey’s Corvette ZR1

What does it take to beat the almighty McLaren 720S in a rolling drag race? A serious amount of power, that’s what.

Hennessy Performance builds some of the fastest vehicles on the planet and recently lined up their Corvette ZR1, complete with their HPE1200 package, alongside a stock McLaren 720S.

A recent dyno run of the Corvette ZR1 in question revealed that its beefed-up supercharged 6.2-liter V8 pumps out 1139 hp and 994 lb-ft (1348 Nm) of torque to the rear wheels. By comparison, the 720S makes 710 HP and 568 lb-ft (770 Nm) at the crank, although, as it has been proven many times, that those figures are rather conservative. Nevertheless, the British supercar has a significant power deficit.

Thus, it’s hardly surprisingly that the ZR1 was able to take the victory without really breaking a sweat. However, the McLaren has to be commended for its effort, because it wasn’t all that much slower than the heavily-modified ZR1 as their respective power figures might suggest – and around a circuit, it might just have been able to keep up.

Interestingly, Hennessey also offers a host of upgrade packages for the 720S as well, including its range-topping HPE1000 package which, as the name implies, lifts grunt to 1000 hp thanks to upgraded turbochargers, stainless steel headers, a tweaked ECU, and improved transmission. If a HPE1000-equipped 720S were to race against the HPE1200 Corvette ZR1, then it would be a much more fair fight – and one we’d be very willing to watch.

    So it took thousands of dollars and a rework of the ZR1 to compete/pass with the “stock” 720S from a rolling start???… This only serves to make the 720S look that much better.
    Next time do a standstill start so we can see the McLaren whip the Vette’s heavily modified tail.

      100% Facts…. I kept saying to myself are we going to do a race from standstill!

    • Merc1

      Ding! We have winner. Exactly.

  • Wandering_Spirit

    Can they put them both on a race track with turns and twists and let us see how it ends?

    • Merc1

      We know how that turns out. The ZR1 would be run into the weeds.

      • Wandering_Spirit

        Precisely.

  • Tabari Lucas

    Hennessy really gets great coverage considering his past horrible business practices/scams..

    • Six_Tymes

      and you get free ability to post lies and to bash people without recourse.

      • Matt

        They’re not lies – it’s well documented.

        • Six_Tymes

          nope, not all. But people here are bashing for a reason, and its not because Hennessy is a bad company either, people here are probably linked somehow to Hennessy competition. So part of it is jealously.

          That company has been producing for a very long time, and would have been out of business a long time ago if it were as bad as the hate spreaders here say, its b. s.

      • Mr. EP9

        He’s not lying, he’s actually telling the truth. It’s well known all the issues Hennessey has had over the years. No refunds for shoddy work, poor customer service, terrible build quality, parting out customer vehicles, overcharging for parts, and numerous lawsuits from disgruntled customers. Not to mention the customer complaints I’ve seen on the Better Business Bureau’s website which resulted them in getting an F rating because many were still unresolved last I checked.

        • Six_Tymes

          No company has a perfect track record, and no I am not referring to racing. Fact, if he and his company were as bad as you guys all BASH over and over, they wouldn’t be in business for as long as they have been. Not sure why you all HATE so much. You enjoy spreading hate towards his company, its obvious you and others here have an agenda.

          Again, his company would not be in business for as long as it has if it were as bad as you say. The constant bashing is weird.

          • Julien Lachemoi

            I have no idea and opinion on the matter but I have one question for you: you really think that because a business is still up it means it can’t be that bad ?

            Because I just know there’s a lot of shady places that rip people off and do a bad job and are still in business.

            It’s a bit like saying a politician wouldn’t be elected if he was bad. Mmh.

          • Mr. EP9

            That’s an absolute lie and you’re full of it. Just because a company is still in business does not mean there isn’t merit to the allegations. Furthermore, all of what I’ve referenced isn’t me spreading hate, as you so erroneously assumed, it’s coming directly from former customers and people who have done business with Hennessey over the years. There is no agenda here, it’s just the honest to god truth you refuse to accept because you don’t like that someone would dare criticize Hennessey. I do still somewhat respect them for their work, but I know they are not the darlings the auto press holds them up to be nor will I pretend that they are.

            And just to further illustrate my point, here’s another company with a really terrible reputation that’s still in business: Electronic Arts

            They’ve made, and continue to make, decisions with their products that has angered consumers – one person in the company openly talked about how to exploit people for financial gain – and yet they haven’t gone out of business much like their competitors that have done something similar. By your own reasoning, because that company is still in business, they can’t be that bad and stating such is spreading hate because of some undisclosed agenda. If you’re going to defend Hennessey you will have to do a better job than that.

          • Hey Jim, where is The Abyss?

            In the automotive pantheon, is there one company more of a mendacious menace to the entire planet than Volkswagen? And they’re still in business.

      • Bo Hanan

        This video is a lie/misleading. If Hennessy’s ZR1 is so great then run a real test and lets see how it ends on the track. I’m not even sure I believe the Vette beat the MAC that bad…

      Good catch

  • miles selim

    I don’t believe this I don’t think this is true and I don’t really care because it’s not like I’m going to own either one. But let’s be honest here, whoever is driving the McLaren isn’t really driving it all. Can’t shift, driving it soft not like they’re racing at all. But who am I ?

    • Bash

      I hear you and I raise you.

  • Mr. EP9

    Not to go all tin foil hat mode but I wouldn’t be surprised if Hennessey were rigging these races just to make their product look better by comparison.

  • Thresher234

    This whole article is dumb. In the video, you can quite clearly hear the 720s short shifting, dropping the rpms below the power band. They do this because they know damn well that they can’t compete. Can’t believe Hennessy would even try to compare themselves to McLaren Smh

  • SteersUright

    Probably still cheaper than the Mac even with all the mods. That said, I did notice the rolling start. Off the line, the ZR1 likely has huge traction issues where McLaren’s get up and going really, really well with their mass over their rear wheels.
