Most of the time when on a racetrack, or anywhere for that matter, you want to keep all four wheels on the ground.

McLaren to bring F1 GTR, LM and Longtail to Goodwood

McLaren is taking the 24 Hours of Le Mans off this year -- actually, it has taken the last 14 years off -- and is instead concentrating on a British tradition: the Goodwood Festival of Speed. The company confirmed it would bring the 1995 Le Mans-winning McLaren F1 GTR to take on the hill this year. It will be joined by the one-off prototype McLaren F1 LM, as well as the Gulf-liveried McLaren F1 GTR Longtail, which claimed second place in 1997.
