in the daytime The race is held in mid-June, near the
summer solstice, meaning the shortest night and very hot conditions for drivers, particularly in closed vehicles with poor ventilation. Rainy weather is common. The race begins in mid-afternoon and finishes the following day at the same hour the race started the previous day. Modern competitors often cover well over . The record is 2010's , more than six times the length of the
Indianapolis 500 (500 mi or 805 km), or about 18 times longer than a
Formula One Grand Prix. Drivers and their teams strive for speed and avoiding mechanical damage, as well as managing the cars' consumables – primarily
fuel,
tires, and
braking materials. It also tests endurance, with drivers frequently racing for over two hours before a relief driver can take over during a pit stop while eating and resting. Current regulations mandate that three drivers share each competing vehicle, with individual limits of driving no more than 4 hours in a 6-hour period, and no more than 14 hours total. Competing teams race in groups called "classes", or cars of similar specification, while competing simultaneously for outright placing amongst all classes. Originally, the race showcased cars as they were sold to the general public, then called "Sports Cars", in contrast with the specialised
racing cars used in
Grand Prix motor racing. Over time, the competing vehicles evolved away from their publicly available road car roots. Today, the race comprises three classes: the purpose-built
Sports prototypes which are also known as "hypercar" and are the highest level in sports car racing,
Le Mans Prototypes (LMP) and the production-based
Grand Touring (GT) cars similar to sports cars sold to the public which are based on road-going models and therefore, in general, are not as fast as Sports prototypes. These are further broken down into: Hypercar (
LMH or
LMDh),
LMP2 and
LMGT3 (GT cars). Competing teams have had a wide variety of organizations, ranging from competition departments of road car manufacturers (eager to prove the supremacy of their products) to professional motor racing teams (representing their commercial backers, some of which are also car manufacturers who want to win without paying for their own teams) to amateur teams (racing as much to compete in the famous race as to claim victory for their commercial partners). The race was part of the
World Sportscar Championship every year from its inception in
1953 until its demise in
1992, except during the
1956,
1975–
1979 and
1989–
1990 seasons. In
2011, the race was part of the
Intercontinental Le Mans Cup, and since
2012 it has been part of the
FIA World Endurance Championship. However, winning Le Mans is often considered to be more important than winning the championship itself. The race is also known as a leg of the informal
Triple Crown of Motorsport which links
Formula One,
IndyCar, and
sports car racing to represent a career achievement for drivers. Additionally, it is seen as a leg of the
Triple Crown of endurance racing, which links the three largest sports car races together, with the
24 Hours of Daytona and
12 Hours of Sebring forming the other legs. Since 1998, an endurance race called "
Petit Le Mans" has been held every year as a 10-hour American version of the Le Mans 24 Hours. From 1999 to 2013, Petit Le Mans was part of the
American Le Mans Series along with the 12 Hours of Sebring. Since 2014, the
IMSA SportsCar Championship (a merger of ALMS and the
Rolex Sports Car Series) has held all four major American endurance classics, which teams can use to prepare for racing at Le Mans.
Cars cars approaching Dunlop Bridge|alt=|left The race has approximately 60 competitors. Each car was required to have at least two seats. However, recently cars only need to have space to accommodate a second seat in the cockpit rather than the seat itself. Two doors are allowed; open cockpit cars do not require doors. Since 2014, all cars in the premier LMP1 category must have a roof due to safety concerns, with open-cockpit cars only permitted in the slightly slower LMP2 category. Since 2017, all prototype cars, Hypercar or LMP2, must have closed cockpits. Although all cars compete at the same time, as of 2021 there are separate classes. A prize is awarded to the winner of each class and the overall winner. The number of classes has varied over the years, but there are now three: Hypercar, LMP2, and LMGT3. Successor to the
Le Mans Prototype 1 (LMP1) is the custom-built Hypercar (LMH or LMDh) class. It is the top class and debuted in 2021. The new technical regulations are intended to prevent cost escalations while enabling greater variety in technical approaches and car aesthetics. This is followed by the LMP2 class where teams are obliged to run one of four approved chassisORECA, Ligier, Dallara, or Multimatic/Rileymated with a standard 4.2-litre Gibson V8 engine. ORECA is the most commonly used LMP2 chassis. LMP1 teams are not subjected to chassis and engine restrictions. Their extra power, lower weight, and more complex aerodynamics result in much quicker lap times; LMP1 cars also may use hybrid technology. The next class is
LMGT3, which are similar to production-based sports cars. The program debuted in 2012.
Drivers Initially, there were no rules on the number of car drivers or how long they could drive. Although almost all teams used two drivers in the early decades, some Le Mans drivers such as
Pierre Levegh and
Eddie Hall attempted to run the race solo, hoping to save time by not having to change drivers. This practice was later banned. Until the 1980s, there were teams in which only two drivers competed, but by the end of the decade, the rules were changed to stipulate that at least three drivers must drive each car. By the 1990s, due to the speeds of the cars and the strain it puts on drivers, additional rules to reduce driver fatigue mandated that drivers could not drive for over 240 minutes (over 4 hours) and that no one driver could run for over 840 minutes (14 hours) total. With careful management of driver stints, this makes it possible to complete the race with only two drivers (as
Jeroen Bleekemolen and Cooper MacNeil did in 2014), although the vast majority of teams still continue to use three drivers. In 2017, the driving time rules were further changed. If necessary, officials may require a drive time limit of 80 minutes of consecutive time behind the wheel and a minimum 30-minute rest break. The rule applies only if the air temperature is at least .
Traditions and unique rules Although it has been a part of the
World Sportscar Championship for most of its existence, the race has had different regulations for safety and competition reasons partly due to its length. For many decades, cars had to run at least an hour into the race before they could refill fluids for the car, such as oil or coolant, except for fuel. This was an attempt by the ACO to help increase efficiency and reliability. Those who could not last the first hour without replacing lost fluids risked disqualification. Another rule unique to Le Mans is that cars must be switched off while refueling in the pits. Not only is this safer and less of a fire hazard, but it is also another test of reliability, demanding a guaranteed ability to restart many times under race conditions. Another element of this rule is that mechanics are not allowed to work on the car while it is being refuelled (other than helping a driver in or out of the car), which has led teams to adapt innovative ways to decrease the time of these lengthy pit stops. Drivers can get out of the car and be replaced by another driver during refuelling. Those rules are also applied in the
FIA World Endurance Championship. There are various long-standing traditions at Le Mans, including the waving of the
French tricolor to start the race. This is usually preceded by a fly-over featuring jets trailing blue, white, and red smoke. A similar flag tradition is track marshals waving safety flags during the race's final lap, congratulating the winners and other finishers. Le Mans was the venue for the first televised instance of a winning driver celebrating by spraying champagne instead of drinking it. When
Dan Gurney won the race with co-driver
A. J. Foyt, the two drivers mounted the victory podium, and Gurney was handed a magnum of champagne. Looking down, he saw Ford CEO
Henry Ford II, team owner
Carroll Shelby and their wives, as well as several journalists who had predicted disaster for the high-profile duo. Gurney shook the bottle and sprayed everyone nearby. Gurney autographed and gave the bottle of champagne to
Life photographer
Flip Schulke, who used it as a lamp for years before returning it to Gurney.
Schedule The first race was held on 26–27 May 1923 and has since been run annually in June with exceptions in 1956, when the race was held in July; 1968, when it was held in September due to nationwide
political turmoil in May; 2020, when it was moved to 19–20 September due to the
COVID-19 outbreak; and 2021, when it was moved to 21–22 August. The race has been cancelled ten timesin 1936 (a labour strike during the
Great Depression) and between 1940 and 1948 (World War II). The race usually takes place on the second weekend of June, with qualifying and practice taking place on the Wednesday and Thursday before the race, following a car inspection on Monday and Tuesday. Currently, these sessions are held in the evening, with two separate two-hour sessions held each night. Friday serves as a day of rest, and a parade of all the drivers through
Le Mans is held. Test days held at the end of April or beginning of May served as a pre-qualification weeding out the slowest cars. However, in 2005 the exorbitant cost of transporting cars to and from Le Mans led organizers to move the test day to the first weekend of June. Pre-qualification was eliminated in 2000, meaning that all competitors invited to the test would be allowed into the race. Since 2001 the
Le Mans Legend races have mostly been part of the schedule, usually running exhibition races during qualifying days, a few hours prior to the sessions for the Le Mans entrants. Since its inception, the race has usually started at 4:00 p.m. local time (Central European Summer Time, UTC + 02:00) on Saturday. The 2025 race is scheduled for 4:00 p.m. Following is a list of exceptions to the standard 4:00 p.m. starting time:
Classification Initially, the car that covered the greatest distance from its starting position was the winner. This is known to have caught out the
Ford team in . With a dominant 1–2 lead, the two cars slowed to allow for a
photo opportunity at the finish line, with
Ken Miles slightly ahead of
Bruce McLaren. However, since McLaren's car had started much farther back on the grid than Miles's, McLaren's car had covered the greatest distance over the 24 hours. With the margin of victory determined to be eight metres, McLaren and his co-driver,
Chris Amon, were declared the winners. The decision cost Miles and
Denny Hulme a victory. Miles had already won the other two endurance races at Sebring and Daytona. With a win at Le Mans, he would have become the first man to win all three and the first to win them all in the same year. The "greatest distance" rule was modified with the introduction of a rolling start in 1971. Now, the car that completes the greatest distance as of the final lap's completionwhere "greatest distance" is measured by the start/finish line for all competitorswins. When two cars finish the same number of laps, their finishing order is determined by the faster overall completion time. This rule was used in the
2011 24 Hours of Le Mans to determine the race winner. The top two finishers completed 355 laps, with only 13 seconds difference between them. Although "greatest distance run" determines the provisional order of finishers, additional requirements must be met for a car to be classified. • A car must complete the last lap of the race and complete the entire circuit faster than a prescribed maximum lap time. Ambiguity in this classification requirement has led to dramatic scenes where damaged cars have waited in the pits or on the edge of the track close to the finish line, restarted their engines, and crawled across the line to be listed amongst classified finishers. The practice of intentionally "waiting for the final lap" in this manner has been prohibited by rule in recent years. • Cars must complete 70 percent of the distance covered by the overall winner to be classified. Even if it finishes the last lap of the race, a car failing to complete this number of laps is not deemed worthy of classification because of poor reliability or speed. All classification requirements hold except in exceptional circumstances, as determined by the race stewards. ==Circuit==
