24h Le Mans
There is no end to the statistics generated by the Le Mans 24 Hours. Here are some of the most surprising, spectacular or fun facts and figures about the race.
4: A driver must be at the wheel for at least 4 hours during the race.
14: On the other hand, the maximum driving time is 14 hours for any one driver.
10: Ten is the minimum number of laps that a driver must complete during the Test Day if he or she is a rookie or has not competed in the Le Mans 24 Hours for over 5 years.
55: The number of cars invited to compete.
56: The additional spot on the grid for vehicles that showcase new and innovative technology.
5: The number of classes in the race: LM P1 hybrids, LM P1, LM P2, LM GTE Pro, LM GTE Am.
12: The quota for the number of sets of slick tyres allowed in LM P1 during the race itself. The other categories are allowed 14 sets. An extra set is available in special cases (punctures, tread separations etc.)
4: The number of mechanics allowed to change tyres. Only two are allowed to work at the same time. Mechanics therefore perform a sort of choreographed dance on each side of the car.
60: The speed limit in the pit lane is 60 kph.
80 kph: The speed limit in a slow zone (in an accident area following a yellow flag)
1,245 kg: The minimum weight for a GTE, not including driver or fuel. The minimum weight for an LM P1 is 850 kg. It is 870 kg for a LM P1 Hybrid and 900 kg for an LM P2.
20: The percentage of biofuel to be used.
370,000: The maximum price of a new open cockpit LM P2 car. Closed cockpits may cost up to €450,000.
5,410.71 km: The longest distance covered during the race. The record was set in 2010 by the n°9 Audi R15 Plus TDI driven by the Bernhard-Dumas-Rockenfeller team.
16.5: Or, to be precise, 16 years and 202 days, is the age of the youngest driver ever to have negotiated the 24 Hours of Le Mans circuit. American Matt McCurry took the wheel of a Zytek in the LM P2 class on 14 June 2014.
405 kph: The highest speed ever reached at Le Mans. Roger Dorchy set the record in 1988 on the Mulsanne Straight in a Peugeot-powered WM P88.
9: The record number of victories, held by Danish driver Tom Kristensen.
13: the number of times Audi has won Le Mans, in 16 runs.
