The beast in its natural habitat.
Watch the McLaren P1 GTR going fast on track during a Blancpain event. And the P1 GTR was not along there, you can also see the astonishing Aston Martin Vulcan.
The McLaren P1 GTR is the track-only version of the “normal” P1 you know. The car is improved in all aspects, from the aerodynamic which gained a lot of components to increase downforce (a large front splitter, canards, a new rear diffuser and, of course, a massive rear wing) to the increase in power, in which the 3.8L V8 twin turbo gained 83 extra ponies totalizing a thousand of them.
