Thank you Mr Andy74B for sharing this with the world. It's joyous. As a combination for a great video, two exceptional McLarens and Silverstone should be pretty special.
And so it proves! Here are seven minutes of onboard from Mr 74B's glorious F1 GTR. Unfortunately he can't stick with the P1 for too long (as the description says, it's "hard work" trying to stay in touch with a car 20 years newer) and lets it pass but that's no bad thing really; since when was watching an F1 at Silverstone tedious?
As always with F1 videos, it's the engine that dominates - the V12 is razor sharp in its response, produces shocking performance and makes one of the most thrilling automotive sounds in history. We often implore you to turn videos up but that sentiment applies even more strongly here!
