McLaren 720S Lays Down Remarkable 698 HP On The Dyno

In a straight line, the new McLaren 720S is only a fraction slower than the mighty McLaren P1 hypercar and according to some, actually faster around certain racetracks than its more powerful and expensive sibling.

How is this possible? Well for one, the 720S makes use of a new 4.0-liter twin-turbocharged V8 engine which McLaren says delivers 710 hp. It also weighs about 250 kg less than the P1. What’s more, it seems as though the automaker has also been very conservative in its power claims for the supercar.

A bone stock 720S was recently strapped to a dyno and in its three runs, delivered a remarkable 694 hp, 696 hp and 698 hp at the rear wheels. Peak torque also reached 560 lb-ft.

Taking into account a 15 per cent drivetrain loss for the rear-wheel supercar, this could mean the new McLaren actually produces around 800 hp at the crank, even more than the Ferrari 812 Superfast is claimed to deliver.

Importantly, no specifics have been provided by Boost Addict about the conditions in which the dyno test in question was conducted but even still, it appears quite obvious that the brand has kept the car’s true power figures close to its chest.

    Now that’s the way you cheat.

  • Vassilis

    Is it possible that McLaren’s claims are wheel HP and not crank HP? I think some manufacturers do that.

    It’s crazy how McLaren overtook Ferrari in only 5 years in desirability. It went from literally vaporware to a must have vehicle. I like the 720 as much as the Aventador now.

      Overtook Ferrari in desirability? Naaaah….still long way to go…. Saying that,I like McLaren’s more and more

      • nastinupe

        If that’s not the case then why is the P1 selling for way more than the LaFerrari on the gray market?

        • alexxx

          You know that for a fact?

  • David mcCreery

    Brad, you use the phrase “what’s more” too much. Just some friendly critique.
