McLaren 720S vs. 829 HP McLaren 650S Drag Race Ends in Technical Knockout

If you're keeping an eye on the street car side of the drag racing realm, you know that the McLaren 720S is currently sending everybody's jaws to the floor. But what if somebody tried to give Woking's latest animal a taste of its own medicine?

To be more precise, we're talking about the owner of a McLaren 650S who commissioned a serious tech massage for his supercar. Once the trip to the gym was completed, the modded 650S duked it out with the 720S and we now have the resulting footage.

The two Maccas went for a street racing approach and, with their drivers being aware of just how many people would check out the outcome, they decided to engage in three separate races.

And, unlike in the case of most drag brawls that comes from the YouTube channel behind this tale, a third vehicle was there. We're talking about a Tesla Model S, whose electric muscle allowed it to be cast in the role of a camera car. Speaking of which, both British missiles packed cameras, so you'll get to see each and every angle of this Brit vs. Brit confrontation.

As for the tuning process, the 650S has gone through, we're talking about a solid hardware upgrade, one involving an Evolution ETV825 pack: upgraded turbos, new cats, an Akrapovic exhaust, as well as the obvious ECU remap. It's worth noting that the thing tips the scales at 3,290 lbs.

This 650S also comes with custom wheels, but you shouldn't expect this detail to make too much of a difference in the battle we're discussing here.

Now, as we've mentioned before, the 720 PS (710 hp) official crank output of the McLaren 720S should be taken with a grain of salt. For one thing, dyno runs have shown that the newcomer delivers around 700 hp at the wheels, which means that its crankshaft output is actually closer to 800 ponies. The generation change has also brought a weight benefit, since the 720S sits at 3,190 lbs.
