The supercar put down nearly 700 horsepower on the dyno.

From the factory the new McLaren 720S is good for as much as 710 horsepower, 568 pound-feet of torque, and a top speed of around 360 kilometres per hour… or so the company says. Thanks to some new dyno figures, we’ve learned that the already powerful supercar might be seriously underrated.

According to BoostAddict, the McLaren 720S pumps out an impressive 698 wheel hp at 6,500 rpm on the dyno, and returns max torque of around 560 lb-ft. That’s a marginally tiny loss of about four percent in power through the drivetrain. If you factor in the "15 percent" loss rule as used in most supercars, the 720S could be producing somewhere near 800 hp.

The dyno figure for the 720S is significantly higher to that of other McLaren supercars tested. The outgoing 675LT produced 582 hp and 490 lb-ft of torque on the dyno, representing a 12 percent loss in power from the 666 hp and 516 lb-ft of torque rated at the crank.

The McLaren 720S is powered by a 4.0-litre biturbo V8 producing the aforementioned 710 hp and 568 lb-ft of torque. Power is routed through a seven-speed dual clutch automatic with a manual shifting mode and four different driving modes: Comfort, Sport, Track, and Drift. All that power is sent to the rear wheels exclusively.

Naturally, with any dyno run we should treat these figures as anecdotal evidence. Similar to the Honda Civic Type R dyno figures we reported just a few weeks back, not every McLaren 720S will put down this type of performance on a rolling road. Still, it’s an impressive figure nonetheless, and proof that McLaren might be undervaluing its latest supercar.
