From McLarenLife:

Got my new copy of EVO magazine today and they have a large spread on the 720's. I won't go into the details of the article but will just look at the point raised above.

In very similar conditions on the same tires at the Anglesey track, the 720s posted 1:11.5 with a record top speed of 143mph vs the P1 at 1:12.6. For comparison, a 488 did a 1:12.8.

Now I suspect on a track where aero comes into play more the P1 would have the 720s. But whatever way you cut it its a remarkable achievement for the 720s which will be produced at a rate of 1400 per year so its no limited production special. Progress is a remarkable thing
