TWO examples of the fabled McLaren P1 GTR will be in action on the Hill over the Goodwood Festival of Speed weekend later this month, between them producing nearly 2,000 horsepower.

The first is entered by McLaren Automotive as part of the Supercar Run and is being fitted with a special livery inspired by James Hunt's race helmet, in honour of the 40th anniversary of his Formula 1 championship win.

The second is entered by Lanzante Ltd and is an extensively modified version of the original which was initially created by McLaren Special Operations.

The most obvious difference between them is that the Lanzante entrant is street legal, meaning the team will attempt to set the fastest time of the weekend for a road car with 1999 Indy 500 winner and McLaren test driver Kenny Brack behind the wheel.
