90-515: The 1929 24 Hours of Le Mans was the 7th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 15 and 16 June 1929. In the most dominant display in the race to date, Bentley achieved a comprehensive victory taking the first four places on distance. Bentley director Woolf Barnato repeated his victory of the previous year, co-driven this time by fellow Bentley Boy Sir Henry “Tim” Birkin . They had led from start to finish, setting

180-541: A break as all applications that year were deemed unfit by the ACO. Frederic Sausset, a quadruple amputee, drove a modified Morgan LMP2 in the 2016 race. Financial problems forced Welter Racing to cancel its 2017 Garage 56 run with the Green4U Panoz Racing GT-EV, a biomethane -fuel prototype featuring a 3-cylinder 1.2-liter engine fueled by biomethane stored in cryogenic tanks. Welter Racing went on to develop

270-452: 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

360-410: 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 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,

450-456: A driving hazard because of its excessive exhaust – broke a fuel line and retired. The Invicta, that had been running as high as 9th at nightfall, was retired when a complete loss of engine-oil had broken a big-end bearing. They had been “the best of the rest”, leading the Lea-Francis, a Tracta, BNC and SARA. Around dawn Clement's Bentley had to stop when the rear ballast came loose and went through

540-434: A four-speed gearbox. The cars were entered by their European dealerships. British agent Warwick Wright had George Eyston /Dick Watney as drivers. Automobiles Elite, of Paris, hired Guy Bouriat and Philippe de Rothschild ; while Paris-based American Charles Terres Weymann had grand-prix master Louis Chiron with the experienced Édouard Brisson. Their car was fitted with an optional Roots-supercharger . Like Stutz, Du Pont

630-551: A hybrid electric car based on the DeltaWing's design, took the Garage 56 slot in 2014. Despite an early retirement from the race after only 23 minutes due to a gearbox issue, the ZEOD RC achieved its goals of hitting a top speed of 300 km/h (186.41 mph), and completing the first ever lap of Le Mans using exclusively electric power at racing speed. In 2015, the Garage 56 program took

720-664: A new distance record and lap record. The race was relatively quiet, without serious incident, aside from a fuel fire burning Stutz driver Édouard Brisson. Half of the reduced field had retired by dawn on the Sunday and the Bentley team was able to stage a formation finish for its four finishers. The international regulations remained unchanged. However, for its part, the Automobile Club de l'Ouest (ACO) decreed that 2-seater cars could now be no bigger than 1000cc (either supercharged or not) and

810-463: A new team of Lagonda-owners (PERR) and the company's main agents, Fox & Nichol, approached the company to prepare four cars for racing. Major revisions were made to the 2-Litre Speed, including lowering the chassis, uprating the engine and fitting a tougher gearbox and suspension, all combining to give it a top speed of 160 kp/h (100 mph). One was entered for Le Mans, driven by Tim Rose-Richards and Brian Lewis, Baron Essendon . By contrast,

900-429: A relief driver can take over during a pit stop while eating and resting. Current regulations mandate that three drivers share each competing vehicle. 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

990-405: A standard 4.2-litre Gibson V8 engine. LMP1 teams are subject to no such 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. Concept cars intended to test new automotive technologies may participate in the race under

1080-560: A standard design in three wheelbase lengths, the 1928 LC (“large-chassis”) version featured the current 4.5-litre Meadows engine that put out 100 bhp. Cecil Twisleton-Wykeham-Fiennes, a major in the Royal Marines , put in a privateer entry for the race. Similarly, Lea-Francis was an English firm manufacturing since 1920. The S-Type had arrived in 1927, with the Meadows 1.5-litre engine used in several English sports cars. Once fitted with

1170-552: A supercharger (as the S-Type Hyper) it could reach 145 kp/h (90 mph) and became very popular with privateer drivers and Kaye Don won the RAC Tourist Trophy handicap. Enthused by this, gentleman racer Ken Peacock entered a car with Lea-Francis distributor Sammy Newsome as his co-pilot. The Lagonda works team had had a very disappointing season in 1928, with only one finish from seven entries in three races. However,

1260-426: A week earlier been used in a 24-hour record-breaking attempt at Montlhéry by Mary Petre and her husband Victor Bruce. The experienced driving squad was supported by Bertie Kensington-Moir, back from Lagonda as team manager, and Walter Hassan as lead mechanic. After the close-fought duel the previous year, Stutz returned with three cars. The new Model M Blackhawk had a 5.3-litre engine capable of 155 bhp through

1350-454: 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 . 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

1440-463: Is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. The cars on this track are able to achieve speeds of 366 km/h (227 mph), and reached 407 km/h (253 mph) on the Mulsanne Straight in 1988  – instigating the addition of more chicanes to the track to reduce speed reached. Racing teams must balance

1530-512: Is one of the races—along with the Monaco Grand Prix and Indianapolis 500 —that form the Triple Crown of Motorsport , and is also one of the races alongside the 24 Hours of Daytona and 12 Hours of Sebring that make up the informal Triple Crown of endurance racing . Run since 1923, it is the oldest active endurance racing event in the world. Unlike fixed-distance races whose winner

1620-451: 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

1710-560: 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 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

1800-672: The 1921 and 1926 French Grand Prix Later he became well known for racing supercharged MGs such as the Magic Midget and the K3 Magnette . His entries with the K3 included the 1933 Isle of Man and 1934 Northern Ireland Tourist Trophy events, and the 1934 Mille Miglia He fitted a diesel engine from an AEC bus into a car built on a Chrysler chassis and used it to set high-speed endurance records at Brooklands , attaining 100.75 mph in 1933 and 106 mph in 1936. In 1935, he

1890-500: The 1969 race, Jacky Ickx opposed it by walking across the track while his competitors ran. Although he was nearly hit by a faster competitor's car while walking, Ickx took the time to fasten his safety belts before pulling away. Privateer John Woolfe died in an accident on the first lap of that race; Ickx won. George Eyston Captain George Edward Thomas Eyston MC OBE (28 June 1897 – 11 June 1979 )

1980-569: The ACO Although there were no official engine classes, the highest finishers in unofficial categories aligned with the Index targets are in Bold text. 24 Hours of Le Mans The 24 Hours of Le Mans (French: 24 Heures du Mans ) is an endurance-focused sports car race held annually near the town of Le Mans , France . It is widely considered to be one of the world's most prestigious races, and

2070-475: The Alvis had been successful and returned with two of their new FA8/15 model. Still with front-wheel drive , the 1.5-litre engine now had a Roots supercharger. Drivers were 1927-winner and journalist Sammy Davis with Leon Cushman and Cyril Paul with Bill Urquhart-Dykes. SARA was the only other manufacturer apart from Bentley to have been at every Le Mans to date. Since the last race founder Auguste Tisserant had sold

2160-515: 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 . 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

2250-473: The "Garage 56" banner. Such entries are classified in the race results, though are not expected to be competitive as their sole focus is to demonstrate experimental features. The program debuted in 2012 with the DeltaWing , an unusual rocket-shaped car fielded by All-American Racers and supported by Nissan. The DeltaWing concept showed promise, delivering nearly LMP2-level performance while only consuming 48% of

2340-582: The 3-seat dispensation for 1500cc cars was removed after two years. This year Shell petrol was the official fuel for all cars. Residents of southern Le Mans city were successful in petitioning the council. A new by-pass road, the Rue de Circuit, was built 600 metres ahead of the Pontlieue hairpin at the edge of the city. It reduced the track length by 922 metres from 17.362 km (10.788 mi) to 16.340 km (10.153 mi). The road surface experiments continued on

2430-499: The ACO deeming none of the applications sufficiently mature. 2020 saw Frederic Sausset attempting to return to Garage 56 under the SRT41 banner by fielding a specially modified Oreca 07 LMP2 car with a lineup of three disabled drivers; however, the attempt was cancelled due to the COVID-19 pandemic . The SRT41 program was delayed to 2021, which saw Garage 56 successfully making a return for

2520-600: The Benjafield/d'Erlanger car, running fourth, got a water leak and electrical fault. By the time the niggly faults were repaired, they were being closely pursued by a resurgent Bouriat and Benoist. Then Benoist's skill as a Grand Prix driver came to the fore in the darkness as he successively overtook the Stutz and the Bentley to push up to fourth by 6am. Just before halftime the Tracta special – which had been in danger of disqualification as

2610-667: The DuPont and the Lagonda but Birkin, in the big Bentley Speed Six, was in the lead under the Dunlop bridge. Left at the line was the D’Yrsan with Trillaud losing seven minutes pushing the car up the road trying to get his engine fired (technically a disqualification offense). At the end of the first lap Birkin had already set a new lap record of 7m57s, from a standing start. The other Bentleys of Clement, Kidston and Benjafield were in formation behind, chased by

2700-501: The LMP category as rules have been changed to their benefit and to further push efficiency. The race is held in mid June, 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 5,000 km. The record

2790-464: The Stutzes of Bouriat and Eyston. Howe was next, though he soon moved up as the rain stopped to join his teammates, with Benoist and Mongin in their Chryslers and Moran's DuPont making up the top ten. Already there was a sizeable gap (over a kilometre) back to the Lagonda leading the smaller cars. After three-quarters of an hour, Earl Howe was in the pits, his progress stymied by electrical issues. Replacing

2880-529: The Tractas rounding out the ten finishers. Team-owner Grégoire almost had a race-ending spin at Arnage near the end of the race, but they were the only French cars to finish this year. It was the most dominant display by a manufacturer in the short history of the race to date, and not matched until 1957 by Jaguar. The leading two Bentleys had not missed a beat. In the mighty Speed Six, Tim Birkin had stamped an impressive new lap record, fully 46 seconds faster, helped by

2970-468: The World 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

3060-399: The bunched field at the start. This starting method inspired Porsche to locate the ignition key switch to the left of the steering wheel. In a left-hand drive car, this allowed the driver to use his left hand to start the engine and his right hand to put the transmission into gear, which in turn shaves off a few tenths of a second. Stirling Moss developed another method for speeding up

3150-491: The car with hopes of entering the car in 2018 and 2019, but ultimately did not compete due to complex issues with the car in 2018, and due to Don Panoz 's death suspending the program in 2019. The 2019 slot was also eyed by UK-based constructor Perrinn with the Project 424, an LMP1-based electric-powered car with an autonomous driving mode; however, this did not come to pass, and Garage 56 was left empty in both 2018 and 2019 due to

3240-427: The car. The car marked NASCAR's 75th anniversary, which coincided with the race's centenary. Chad Knaus , Johnson's crew chief during each of his Cup Series championships, was project manager, while the car bore #24 in honor of Hendrick vice chairman and former driver Jeff Gordon . 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

3330-668: The cars in the field. Of the sixteen places open in the Biennial Cup final, thirteen were taken up. Belying its precarious financial position, defending winners Bentley arrived with a very strong five-car entry, led by the new Speed Six sport version of its 6½-litre tourer. The engine was developed by Harry Weslake using a magnesium-alloy ( elektron ) crankcase to reduce weight. It put out over 190 bhp and get to 185 kp/h (115 mph). The previous year's winner, and company director, Woolf Barnato would drive it with Henry “Tim” Birkin . Another Le Mans winner, Dudley Benjafield ,

3420-502: The clutch gave out. Then at 7 am, Eyston's Stutz ran out of fuel out on the track (with just a lap before his next pit-stop) because of a split fuel tank, leaving just one Stutz in the running. A similar malady then forced the Chrysler to pit. Stoffel was under his car for nearly two hours doing extended repairs. That restored the Bentleys to the top four positions. The Lea-Francis had moved up

3510-496: The demands of speed with the cars' ability to run for 24 hours without mechanical failure. The race is organized by the Automobile Club de l'Ouest (ACO). It is held on the Circuit de la Sarthe , composed of closed public roads and dedicated sections of a 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

3600-574: The distance victory in 1924 . Feeling very pleased with his consecutive victories, Barnato loaned Bentley another £25000. In August, the innovative supercharging pioneer René Cozette was killed making a speed-record attempt when he crashed at 200 kp/h at Montlhéry.In November, Kidston was badly burned when he was the sole survivor in an air-crash in England of a Luft Hansa passenger flight. Results taken from Quentin Spurring's book, officially licensed by

3690-650: 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 the 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, hybrid systems (flywheel, super-capacitor, battery coupled with both petrol and diesel) have been championed in

3780-405: 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

3870-479: The famous race as to claim victory for their commercial partners). The race was a part of the World Sportscar Championship in every season from its inception in 1953 until its demise in 1992 except the 1956 , 1975 – 1979 and 1989 – 1990 seasons , and since 2012 the race has been the part of the FIA World Endurance Championship . However, Le Mans has always had a stronger reputation than

3960-532: The first time in five years. Two of the drivers, paralyzed from the waist down, became the first disabled teammates to compete in the history of the race. In 2022, Garage 56 was once again empty. For 2023, a modified NASCAR Cup Series Next Gen Chevrolet Camaro ZL1 stock car fielded by Hendrick Motorsports was the Garage 56 entry, with seven-times Cup champion Jimmie Johnson , 2009 Formula One world champion and NASCAR driver Jenson Button , and 2010 Le Mans overall and LMP1 winner Mike Rockenfeller driving

4050-440: 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 completion—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

4140-522: The floorboards, damaging the suspension. He lost an hour undertaking repair. So, as the spectators were rousing for breakfast, there were only a dozen cars left running. Barnato and Birkin were still running smoothly out in front. Kidston and Dunfee were now only a lap ahead of the Benoist/Stoffel Chrysler. Behind were the two delayed Bentleys and the two Stutzes. Chiron's solo-drive through the night had finally come to an end just after dawn when

4230-562: The fuel, but retired after a collision with an LMP1 car six hours into the race. In 2013, Garage 56 was given to the Swiss-designed hydrogen-fueled GreenGT H2, which was to be the first car without an internal combustion engine to compete at Le Mans. However, the car was pronounced unfit to take part in the race by the team a few days before the race. In 2016, the H2 went on to complete a single demonstration lap at Le Mans. The Nissan ZEOD RC ,

4320-423: 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

4410-661: 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. 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

4500-487: The hot exhaust of Brisson's Stutz which quickly burst into flames. Brisson was burnt and had to be taken to hospital. After extended repairs to the car, Grand Prix driver Louis Chiron resolved to carry on driving solo. Overtaken by the Alvis, the Lagonda was still going well until Lewis bought the car into the pits, saying the floorboards has been on fire. Initially thought it was thought a hot exhaust pipe had got bent, but when it

4590-527: The layout of the track required 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

4680-503: The license for his patented air-cooled pushrod engine to Scottish entrepreneur H.E. Plaister's new company Scotsman Motors who intended to manufacture touring cars around the 1.5 and 1.8-litre engines. In a joint-venture the companies entered a pair of four-year-old SARA SP-7s for SARA works driver Gaston Mottet along with three British drivers. The success of Tracta ’s patented front-wheel drive system had attracted considerable investment from Charles Terres Weymann , which helped to allow

4770-446: The loudest, and smokiest, car in the race. Bollack Netter and Co (BNC) had collapsed and been bought out by entrepreneur Charles de Ricou, who would also buy the struggling Rolland Pilain and Lombard companies. Two new models came to Le Mans: the four-seater Acacias, with a supercharged 1.5-litre Meadows engine, and a pair of the BNC 527, with its small 1-litre Ruby engine. One of those

4860-494: The night, the Bentley team kept building their lead. Dunfee lost second place when he had to pit to replace his lightbulbs, which had burnt out their wiring while he was doing 100mph down the Mulsanne Straight . He was livid when he found out the mechanics had installed bigger replacement bulbs for the event. Stoffel started pushing his Chrysler when he took over at 2am, making up ground with his track experience. Then around 3am

4950-401: The order through the night to eighth and was running well when one of the shock-absorbers broke. Despite a rough ride they made it to the finish. From there it was a routine run to the finish. With over 700 km (430 mi) spreading the small field, the only real point of excitement was the Chrysler trying hard to reel in the Stutz to take fifth place. In the last hour, W. O. Bentley put

5040-762: The other legs. Since 1998, the American Le Mans Series (now the IMSA Weathertech Sports Car Championship ) has held 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

5130-410: 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. 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

5220-567: The previous year) and Alfredo Luis Miranda (the Mexican-born New York dealer for DuPont). Once again, the Grand Garage St Didier entered two of their Chrysler Six 's. The ‘75’ was the 1929 model, driven by team regular Henri Stoffel, this time along with French GP racer Robert Benoist . The ‘77’ was a preview of the 1930 model and manned by Cyril de Vere and Marcel Mongin. Invicta was an English firm founded in 1919. Offering

5310-530: The public. These are further broken down into two sub-classes: constructors' prototypes, privateer prototypes, and two subclasses of 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

5400-454: 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

5490-551: The race returning to its original start time of 16:00 in 2021, 2023 and 2024 respectively. The only exceptions were as follows: 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 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 started much farther back on

5580-502: The race stewards. The race traditionally began with what became known as the Le Mans start , in which cars were lined up along the length of the pits. Until 1962, cars lined up by engine capacity. Beginning in 1963, qualifying times determined the lineup. The starting drivers stood on the opposite side of the front stretch. When the French flag dropped to signify the start, the drivers ran across

5670-483: The slightly abbreviated track layout. They also broke the race distance record, covering over 2,800 km (1,700 mi). The Speed Six's performance was so strong that they also won all three major awards, becoming the biggest car to win the Index. In finishing fourth, Frank Clement has the distinction of being the only driver to have participated in all seven of the Le Mans through the 1920s, all for Bentley and including

5760-530: The sparkplugs and the magneto took an hour but was ultimately unsuccessful. The DuPont retired with a bent propshaft badly affecting its handling. Unlike most other teams who now used secured lead weights, the team had loaded their ballast as sandbags. These had broken through the floor and damaged the propshaft. With their twenty lap minimum done, the other cars started making their first pit stops for driver changes and refuelling. The well-drilled Bentley drivers were in and out in 3minutes. Alarmingly, fuel spilled onto

5850-484: 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 two classes: the purpose-built Sports prototypes which are also known as Le Mans Prototypes (LMP) and are the highest level in sports car racing, and the production-based Grand Touring (GT) cars which are similar to sports cars sold to

5940-420: 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

6030-408: The start. His car was waiting with first gear already engaged. He switched the starter on when he jumped in without depressing the clutch. The starter motor immediately jerked the car forward, but the engine did not start due to low RPM. After a few seconds of motion, he pushed the clutch down, allowing the engine to speed up and start while the car was moving. Feeling this type of start was unsafe, in

6120-430: The team to enter four cars to the race. The new regulations meant their two-seater Type A could only have a 1-litre engine, but each SCAP engine was fitted with a Cozette supercharger. Once again, owner Jean-Albert Grégoire drove one of his cars. Lucien Lemesle, the mechanic in the crowd who had volunteered to help Grégoire in the debacle that was their 1927 race, returned as a co-driver to Maurice Benoist. The fourth car

6210-608: 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 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. From its inception, until 2008, the race started at 16:00 local time on Saturday, and consequently from 2009 to 2019, 2022 and come 2025 & hereafter it started at 15:00 local time, with

6300-478: 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 followed by a fly-over featuring jets trailing blue, white, and red smoke. A similar flag tradition

6390-466: The track at the start of the week, to familiarise themselves with the circuit and the new layout in unofficial practices (with the roads still for public use). After testing and a shake-down run for the DuPont at the Montlhéry circuit, Moran was concerned about Miranda's lack of pace and decided to drive the whole event himself. Once again, the race began under grey clouds and drizzling rain. First away were

6480-423: The track, entered and started their cars without assistance, and drove away. This became a safety issue in the late 1960s when some drivers ignored their safety harnesses, then a recent invention. This led to drivers running the first few laps either improperly harnessed due to attempting to do it while driving or sometimes not even harnessed at all, leading to several deaths when cars were involved in accidents due to

6570-428: The track. The left-hand turn approaching Arnage was partially re-surfaced with bricks and named Indianapolis , after the famous American “Brickyard”. A new spectator area was opened between the two corners. Also, many roadside trees had their trunks painted white for visibility and all the corners were signposted. The media centre was also enlarged to include six phone booths and a telegraph table. The global recession

6660-443: 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 32 °C (89.6 °F). Although it has been a part of the World Sportscar Championship for most of its existence,

6750-595: The war he returned to Trinity College and was captain of the First Trinity Boat Club . Eyston's racing career began before World War One, when he was still a schoolboy, and raced motorcycles under an assumed name. After the war (in which he was awarded the Military Cross ) he reverted to his own name, moved on to car racing and entered European road races, particularly in Bugattis , with success in races such as

6840-445: The word out to his team to line up for a formation finish. Quite a novelty at the time, the “Motor” magazine described it as “superb, disposed in line ahead like a squadron of battleships.” Bouriat/Rothschild bought the Stutz home in fifth, barely a lap ahead of the hard-charging Benoist in his Chrysler, with his teammate three laps further back. Ken Peacock's privateer Lea-Francis was the first smaller-engined car, in eighth, with two of

6930-608: 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 chassis—ORECA, Ligier, Dallara, or Multimatic/Riley—mated with

7020-521: Was a British engineer, inventor , and racing driver best known for breaking the land speed record three times between 1937 and 1939. George Eyston was educated at Stonyhurst College and Trinity College, Cambridge . His study of engineering at Cambridge was interrupted by World War I when he was commissioned in the Dorset Regiment and later served in the Royal Field Artillery . After

7110-558: Was a part of the Intercontinental Le Mans Cup . Since 2012 , the race has been a part of the FIA World Endurance Championship . In the 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. Launched when Grand Prix motor racing was the dominant form of motorsport throughout Europe, Le Mans was designed to present

7200-423: Was a streamliner special. The unique Cozette engine had opposed pistons at each end of the cylinders powered by the supercharger pressure, thus dispensing with a cylinder head and crankcase. Grégoire prudently assigned his head mechanic Tribaudot, who had assembled the engine, to co-drive Roger Bourcier (given the rule that only the drivers could work on the car during the race). Its distinctive engine easily made it

7290-640: Was also involved in the design of his Thunderbolt car at the Bean Cars factory in Tipton , Staffordshire (now West Midlands ). As an engineer and inventor, he held a number of patents related to motor engineering and particularly supercharging. His work on developing high-power gearboxes was important for Thunderbolt , along with his invention of the Powerplus supercharger used on MGs . During World War II Eyston served on various bodies connected with industry and

7380-460: Was also took the entry in the Biennial Cup. Smallest car in the field was the D’Yrsan Grand Sport. After withdrawing its entries for the 1928 race, the company arrived this year. The low-slung car had a patented independent front suspension and ran with a supercharged 749cc Ruby engine. A normally-aspirated 1.1-litre entry was also submitted, but later withdrawn. The British teams got to

7470-482: Was found to have a leak from a head gasket the team's race was over. In the meantime, the Alvis had also been put out, with a cracked cylinder head. By 10pm as night fell, Barnato and Dunfee, having completed 44 laps, now had a lap's lead on the rest of the field. The remaining two Bentleys were next, themselves with a lap over Bouriat's Stutz (42) and with Eyston's Stutz and the Chryslers a further lap back (41). Through

7560-531: Was friendly, and in later years Eyston, as competitions manager for Castrol , assisted with Cobb's ill-fated attempt on the water speed record in Crusader . Thunderbolt's first record was set at 312.00 mph (502.12 km/h) on 19 November 1937 on the Bonneville Salt Flats. Within a year Thunderbolt returned with improved aerodynamics and raised its record to 345.50 mph (556.03 km/h) on 27 August 1938. Eyston

7650-523: Was hitting the auto-industry hard and only 26 cars made it to the start-line. For the first time French cars were in the minority with none in line for outright distance honours. It became a three-nation entry list with cars only from France, Great Britain and the United States. In lieu of a lack of direct manufacturer support, more privateer entries arrived. Supercharged engines were very popular with ten cars having ‘blown’ engines. Dunlop Tyres now shod all

7740-535: Was in the American luxury car market. The new Model G had a big 5.3-litre Continental sidevalve engine . However, this was a two-seater tourer, and refused entry by the ACO under its new maximum engine-size rule. So, the company quickly fashioned four four-seater speedster models, however only one of the two entries was ready in time for the race. It would be driven by the first Americans at Le Mans – Charles Moran Jr. (a friend of E. Paul du Pont , who had raced in Europe

7830-512: 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 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

7920-508: Was one of the first British racers to travel to the Bonneville salt flats of Utah , with his 24- and 48-hour record-setting car Speed of the Wind . He is best known today for land speed records set in his car Thunderbolt . Between 1937 and 1939 he set three new land speed records, wresting them from Malcolm Campbell 's Blue Bird , but was twice bettered by John Cobb . The rivalry

8010-462: Was slated to drive the car, but he gave his place to Birkin believing he would have a better chance of winning. The remaining four cars were the reliable 4½-litre tourers, the chassis strengthened after the issues from the previous year. They were assigned to more of the “ Bentley Boys ”: Frank Clement / Jean Chassagne , Benjafield with Baron André d’Erlanger and Glen Kidston / Jack Dunfee . The fourth car, of Earl Howe / Bernard Rubin , had only

8100-401: 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. All classification requirements hold except in exceptional circumstances, as determined by
