Yes it is !

Although the one that I saw was swamped in Carbon which I guess will aid in reducing weight over a standard Pista and would get it off the line quicker and it had more exotic rubber.

Like the Pista colour, impressive from the 720

Whoever owns the 720 will be delighted to hear its only maybe depreciated £30k

Impressive result for the 720S - all about traction off the line initially, as the Lambo shows, the reason it pulls away towards the end, a higher speeds, is really about power to drag ratio. The 720 has a much lower drag coefficient compared to the Pista so with the similar power will simply pull ahead.

My 720S will be going on a dyno run at RE Performance so will post the details up.
Looking forward to seeing the results - i have seen some stock cars at 730-740 bhp

Please remember it’s an estimate of power output at the flywheel, as the actual power output measured on a car dyno is at the wheel.

One of the reason why people in the field believe McLarens have less driveline losses (less power lost due to driveline frictions) so to justify results seen on the road...

Aero obviously can only be accounted when on the road (or measured in wind tunnel).

Thorney have done a video on this - in their tests McLaren's were consistently at 15% (or there abouts) loss which when converted back to official quoted figures from McLaren, were pretty spot on.

Yes but Thorney 15% it’s a value he used after speaking to a McLaren engineer, it’s not a driveline loss value measured by Thorney.

Even though it won, the only reason the 720S didn't utterly annihilate the others completely was its rubbish P Zero tyres.

With decent rubber (corsa, or especially Trofeo), it is incredible.
