Unofficially, I’ve driven le Circuit de la Sarthe
One of the great duels at the classic 24 Heures du Mans was between the Ford GT40 and Ferrari 330, which the Ford won in 1966, 1967, 1968, and 1969, beating the Ferrari which had been victorious every year from 1960 to 1965. The Ford was called the GT40 because its roof was 40 inches from the road.
Of British cars that won at le Mans, the Bentley Speed Six won 5 times between 1924 -30, and the Jaguars C and D types won 5 times between 1951 and 1956. Even with the new kink half-way down, the 3.7 mile Mulsanne Straight is terrifying, especially when you reach the hard right at the village of Mulsanne.
The Circuit du Sarthe is eight-and-a-half miles long in all.
Sadly, Steve McQueen never raced there, although he did race at Sebring.
