That puts the $1.15 million P1 in rarefied company. Only three production cars have done the same: the Radical SR8, Radical SR8LM, and Porsche 918 Spyder.
McLaren won't give an exact lap time. But it does say that the P1 averaged over 111 mph on the 13-mile circuit. That sounds reasonable for a supercar that can hit 217 mph - until you look at the course itself. It includes 154 corners and 300 meters of elevation changes. Here's a map:
