2019 Corvette ZR1 Thinks 755 HP Is Enough To Beat McLaren’s 720S

By all accounts, the all-new Corvette ZR1 seems to be an extraordinary machine, capable of defeating or at least keeping up with just about anything else on the road.

Underneath, beats a 6.2-liter supercharged V8 heart, producing a massive 755 HP (765 PS) and 715 lb-ft (968 Nm) of torque. It’s all directed to the rear wheels with the help of an 8-speed automatic transmission. Point it in any direction and you’ll be doing 60 mph (96 km/h) in just 2.85 seconds, on your way to a maximum of 212 mph (341 km/h).

So yes, it’s no joke, especially not after it edged out the Ford GT at Virginia Raceway with a time of 2:37.25.

Unfortunately, its opponent here is a McLaren 720S, the car that dethroned the modded Porsche 911 Turbo as the de facto vehicle you definitely don’t want to mess with in a straight line.

The 720S is so fast, it can put up hypercar numbers, both to 60 mph as well as over a 1/4 mile. On top of that, it also boasts great aerodynamics, making it extremely slippery, which tends to come in handy the faster you go. Also, it’s thought to have a lot more power than advertised, which is indeed an issue – for anyone hoping to outrace it.

So how well did the ZR1 do compared to the 720S? The two cars were raced both from a standstill as well as from a roll and…there’s no other way to put it: one of them got obliterated.

    Will be interesting to see what the mid engine Vette will do against. Similar powered vehicles

    • Bo Hanan

      Chevy still has time to buy, strip, and dissect a 720S.

      • Bob

        I wonder if McLaren will be running something else in this segment by then.

        • Bo Hanan

          They will.

  • HaltestelleLuitpolthafen

    That wasn’t even remotely close.

    I’d like to see their usual highway pulls, possible heatsoak as an issue???

    For a second, At the start of the first race, I thought, “Woah”, then, 2 seconds later, “oh that’s normal”

  • kachuks

    That first race where the McL actually missed the signal is all I needed to see.

  • Dude[Check JoinDate InProfile]

    Corvette gave it a good try. Not too shabby for being about half the price. And it actually looks really cool. Not better than the 720s imo but still cool.

  • Stratos

    There’s gotta be a huge discrepancy in horsepower! Notwithstanding the fact on a hot day a turbo will pack more air than a supercharger

  • Bo Hanan

    That MacLaren forgot it was racing and was headed towards a black hole.
    At this rate even the new (600LT) baby-MAC would whip the ZR1.

  • DMax

    Well the 720S’ real power output is about 800, plus it’s 400lbs lighter, so nothing surprising here.

    • aero, power delivery, tires, engine management, wheelbase… it’s more than that. More horse power maybe, lighter sure. But how all this works together that’s the story. Put 800 hp in a Smart car, it won’t work well :-D.

    • Don’t fear the future


      At least 800hp. Maybe that’s why the engine of the McLaren is called the M840T.

      The McLaren puts up about 700hp on the dyno. (at the wheels). At a 17% loss (totally realistic number) of power to the rear wheel would mean 840hp at the crank.

      ZR 1 loses only 11% (which is amazing really) to make 667hp at the wheels.

      Does this look like a 840hp car versus a 750hp car? It does to me.

      It all makes sense right.

  • Six_Tymes

    The Raccoon is sure a fast slippery beast

  • SteersUright


    • Don’t fear the future

      Nope. That McLaren’s engine makes over 800hp, 700hp at the wheels. ZR1 engine makes 750hp. 667 at the wheels.

      Both vehicles have been Dyno’d. Those are the facts.

      Shouldn’t be a surprise. But the name 720s make people ASSUME the engine makes 720hp AT THE CRANK. It doesn’t. It makes much more than that at the crank.

      Therefore we are seeing an over 800hp car versus a heavier, with a lot of downforce, 750hp car.

      • SteersUright

        What I meant was, have you seen how a RWD McLaren takes off?? You’d damn near think it had AWD. Have you seen it on a track? Corvettes are capable but they are no longer real bargains, they have gotten expensive. Yet they still require the same ham-fisted techniques around a track and struggle to put their great power down in a straightline all while also bundling along shoddy build quality, lack of refinement, and one of the worst interiors in any high-price sports car. Seriously, some low-volume kit cars already better it.
        Lets stop making excuses. We all want brilliant American cars. The Corvette has its virtues, but it certainly also has its flaws.

        • Don’t fear the future

          The Mclaren is midengine vs Corvette is front engine. Hence the great take-off. (all the weight in the back versus the front). This may change next year for the Corvette.

          The other technologies the McLaren has, the quality of the Mclaren might be possible cause it literally costs twice as much as the Corvette.

          I’ve seen videos of the Corvette on the track. And it is documented the ZR1 is 2 seconds faster around the Nurburgring than this Mclaren; and that was accomplished unofficially with other cars on the track (in traffic). I wonder what time the ZR1 would put up if there was no other cars on the track (like when the McLaren got its official time, 7:14)

          The Corvette is Raw. It’s like an analog machine in a digital world. Much like my nephews 22 year old friend’s dragster, which can smoke both these cars with no doubt at all; and for a fraction of the price. American cars have that Muscle Car lineage. Muscle Car people don’t want refined. They want nasty sounding, large volume displacement mayhem. (again, like my nephews friends dragster)

          Just my 2 cents.

        • Don’t fear the future

          However, I do agree that they could make the ZR1 a little more well rounded. I think Chevy is all about the “Ring” right now and don’t mind that they can’t get the power down on zero to something pulls.

          I also won’t say a ZR1 is a great overall value. It is a strictly performance based value.

          So I do agree there are areas where they can improve. No doubt.
