Le Mans 24 Hours
The 24 Hours of Le Mans (French: 24 Heures du Mans) is the world's oldest active sports car race in endurance racing, held annually since 1923 near the town of Le Mans, France.[1] It is considered one of the most prestigious automobile races in the world[2] and has been called the "Grand Prix of Endurance and Efficiency". The event represents one leg of the Triple Crown of Motorsport, other events being the Indianapolis 500 and the Monaco Grand Prix. Unlike fixed-distance races whose winner is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. In the 2018 race, 41 of the 60 qualifying cars ran the full duration.[3]
The race is organized by the Automobile Club de l'Ouest (ACO) and is held on the Circuit de la Sarthe, which is composed of closed public roads and dedicated sections of racing track.
The 24 Hours of Le Mans was frequently part of the World Sportscar Championship from 1953 until that series' final season in 1992. In 2011, it was a part of the Intercontinental Le Mans Cup. Since 2012, the race has been a part of the FIA World Endurance Championship.[4] In World Endurance Championship's super-season of May 2018 to June 2019, the 24 Hours of Le Mans was both the second and the last round of the season.[5]
Le Mans inspired 24-hour races around the globe, including at Daytona, Nürburgring, Spa-Francorchamps, and Bathurst. The American Le Mans Series and Europe's Le Mans Series of multi-event sports car championships were spun off from 24 Hours of Le Mans regulations. Other races include the Le Mans Classic, a race for historic Le Mans race cars from years past held on the Circuit de la Sarthe, a motorcycle version of the race which is held on the shortened Bugatti version of the same circuit, a kart race (24 Heures Karting), a truck race (24 Heures Camions), and a parody race 24 Hours of LeMons.
Purpose
Launched when Grand Prix motor racing was the dominant form of motorsport throughout Europe, Le Mans was designed to present a different test. Instead of focusing on the ability of a car company to build the fastest machines, the 24 Hours of Le Mans would instead concentrate on the ability of manufacturers to build sporty yet reliable cars. This encouraged innovation in producing reliable and fuel-efficient vehicles, because endurance racing requires cars that last and spend as little time in the pits as possible.
At the same time, the layout of the track necessitated cars with better aerodynamics and stability at high speeds. While this was shared with Grand Prix racing, few tracks in Europe had straights of a length comparable to the Mulsanne. Additionally, because the road is public and thus not as meticulously maintained as permanent racing circuits, racing puts more strain on the parts, increasing the importance of reliability.
The oil crisis in the early 1970s led organizers to adopt a fuel economy formula known as Group C that limited the amount of fuel each car was allowed. Although it was later abandoned, fuel economy remains important as new fuel sources reduce time spent during pit stops. Such technological innovations have had a trickle-down effect and can be incorporated into consumer cars. This has also led to faster and more exotic supercars as manufacturers seek to develop faster road cars in order to develop them into even faster GT cars.
Additionally, in recent years hybrid systems (flywheel, super-capacitor, battery coupled with both gasoline and diesel) have been championed in the LMP category as rules have been changed to their benefit and to further push efficiency.
Race
The race is held in June, leading at times to very hot conditions for drivers, particularly in closed vehicles with poor ventilation; rain is commonly seen. The race begins in mid-afternoon and finishes the following day at the same hour the race started the previous day.[6]
Modern competitors often cover well over 5,000 km. The record is 2010's 5,410 km (3,360 mi), six times the length of the Indianapolis 500, or about 18 times longer than a Formula One Grand Prix.[7] Drivers and racing 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 they eat and rest. Current regulations mandate that three drivers share each competing vehicle.
Competing teams race in groups called "classes", or cars of similar specification, while also 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, and today the race is made of two overall classes: prototypes, and Grand Touring cars (similar to sports cars sold to the public). These are further broken down into 2 sub-classes each, constructors' prototypes, privateer prototypes and 2 subclasses of GT cars
Competing teams have had a wide variety of organization, 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 the part of the World Sportscar Championship in every season except of the 1956, 1975-1979 and 1989-1990 seasons, although Le Mans has always had a stronger reputation than the World Championship, and is a round of the FIA World Endurance Championship. 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 12 Hours of Sebring and 24 Hours of Daytona forming the other legs. Since 1998, the American Le Mans Series (now the IMSA Weathertech Sports Car Championship) holds an endurance race, along with the 12 hours of Sebring, every year called "Petit Le Mans", as a 10-hour American version. In 2014, the Weathertech Sports Car Championship (a merger of the races at Sebring; Petit Le Mans in Braselton, Georgia; the 6 Hours of Watkins Glen in Watkins Glen, New York; and the Rolex Sports Car Series' 24 Hours of Daytona) held all four major American endurance classics in preparation for teams to race at Le Mans.
Cars
The race has approximately 60 competitors. Each car was required to have at least two seats, but recently cars only need the ability to accommodate a second seat in the cockpit rather than the seat itself. No more than 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, LMP1 or LMP2, must have closed cockpits.[9]
Although all cars compete at the same time, there are separate classes. A prize is awarded to the winner of each class, and to the overall winner. The number of classes has varied over the years, but there are now four. Custom-built Le Mans Prototypes (LMP) are the top two classes, LMP1 and LMP2, divided by speed, weight, and power output.
For LMP2, teams are obliged to run one of four approved chassis – ORECA, Ligier, Dallara or Multimatic/Riley – mated with a standard 4.2-litre Gibson V8 engine. LMP1 teams are subject to no such restrictions, however, and their extra power, lower weight and more complex aerodynamics results in much quicker lap times; LMP1 cars are also permitted to use hybrid technology [10]
From 2011, the next two classes are production-based grand tourer (GT) classes, GT Endurance Pro and GT Endurance AM. Both of these classes use the LM GTE, or "Le Mans Grand Touring Endurance" regulations. Although the top class is the most likely to be the overall winner, lower classes have won on occasion due to better reliability.[citation needed]
Drivers
Originally, there were no rules on the number of drivers of a car, 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 a 6-hour period, and that no one driver could run for over 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.[11][12]
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 32 Celsius (89.6 F).[13]
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 were required to run at least an hour into the race before they were allowed to refill fluids for the car, such as oil or coolant, with the exception of fuel. This was an attempt by the ACO to help increase efficiency and reliability. Those who could not last the first hour without having to replace lost fluids risked disqualification.
Another rule unique to Le Mans is that cars must be switched off while they are refuelled in the pits. Not only is this safer and less of a fire hazard, but it is also another test of reliability, as cars with the guaranteed ability to restart many times under race conditions are harder to make. 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 in which to decrease the time of these lengthy pit stops. Drivers are allowed to get out of the car and be replaced by another driver during refuelling. Those rules are also in application 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 followed by a fly-over featuring jets trailing blue, white and red smoke. A similar flag tradition is the waving of safety flags during the final lap of the race by track marshals, 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.[14] When Dan Gurney won the 1967 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.[15][16]
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 & in 2020, when it was moved to 19–20 September due to the COVID-19 outbreak. The race has been cancelled ten times—in 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. In fact 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 also been part of the schedule, usually running exhibition races during qualifying days, a few hours prior to the sessions for the Le Mans entrants.
Until 2008, the race started at 16:00 on Saturday (though in 1968, the race started at 14:00 due to the lateness of the race on the calendar). In 1984 and 2007, the start time was moved ahead to 15:00 due to the conflicting election). In 2006, the ACO scheduled a 17:00 start time on Saturday, 17 June in order to maximise television coverage in between the World Cup games. Since 2009, when the race took place from 13–14 June, it starts at 15:00 local time (CEST, 13:00 UT). One exception is 2020, when it'll start a half-hour earlier.
Classification
Originally, 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 1966. 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 actually started much farther back on the grid than Miles's, McLaren's car had actually 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 not only the first man to win all three, but 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, and now the car that completes the greatest distance as of the completion of the final lap – where "greatest distance" is measured by the start/finish line for all competitors – wins. 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, when the top two finishers both completed 355 laps, with only 13 seconds difference between them.[17]
Although "greatest distance run" determines the provisional order of finishers, additional requirements must be met for a car to be classified.[18]
A car must complete the last lap of the race, and must 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, then restarted their engines and crawled across the line to be listed amongst classified finishers.[citation needed] 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. A car failing to complete this number of laps, even if it finishes the last lap of the race, 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
