The Circuit de la Sarthe, known for its Circuit des 24 Heures du Mans variation after the 24-hour semi-permanent circuit, located in Le Mans, Sarthe, France, is a permanent auto sport circuit. It is the host of the 24 Hours of Le Mans auto race and widely known as the site of the 1955 Le Mans disaster, the deadliest event in motorsport history.
The track comprises a combination of private, race-specific sections of track in addition to public roads used only during the 24 Hours of Le Mans which remain accessible most of the year. Its present 24 hour configuration is 13.626 km (8.467 mi) long, making it one of the longest circuits in the world. The capacity of the permanent race track the short Bugatti Circuit is 100,000. The Musée des 24 Heures du Mans is a motorsport museum for the 24 hours of Le Mans located at the main entrance of the venue.
Up to 85% of the 24 hour circuit lap time is spent on full throttle, putting immense stress on engine and drivetrain components. Additionally, the times spent reaching maximum speed also mean tremendous wear on the brakes and suspension as cars must slow from over 322 km/h (200 mph) to around 100 km/h (62 mph) for the sharp corner at the village of Mulsanne.

Track modifications
The road racing track, which was a triangle from Le Mans down south to Mulsanne, northwest to Arnage, and back north to Le Mans, has undergone many modifications over the years, with CIRCUIT N°15 being in use since 2018. Even with the modifications over the years, the Sarthe circuit remains very fast, with prototype cars achieving average lap speeds in excess of 240 km/h (150 mph).
In the 1920s, the cars drove from the present pits on Rue de Laigné straight into the city, then took a sharp right-hand corner near the river Huisne Pontlieue bridge (a hairpin removed from the circuit in 1929). They left the city on the rather straight section now named Avenue Georges Durand after the race's founder. Then 17.261 km (10.725 mi) long and unpaved, a bypass within the city shortened the track in 1929. The city was bypassed completely in 1932 with the addition of the section from the pits via the Dunlop Bridge and the Esses to Tertre Rouge. This classic configuration was 13.492 km (8.384 mi) long and remained almost unaltered even after the 1955 tragedy. Its frighteningly narrow pit straight was further narrowed to make room for the pits and was part of the road itself, without the road becoming wider around the pits, and no separation. The pit straight then was about 3.7 m (12 ft) wide, further widened in 1956 after the tragedy, but the race track and pits were not separated for another 15 years.
Car speeds increased dramatically in the 1960s, pushing the limits of the "classic circuit" and sparking criticism of the track as being unsafe after drivers died during trials. In 1965, a smaller Bugatti Circuit was added which shares the pit lane facilities and the first corner (including the famous Dunlop bridge) with the full "Le Mans" circuit. For the 1968 race, the Ford chicane was added before the pits to slow down the cars. The circuit was fitted with Armco barriers for the 1969 race. The "Maison Blanche" kink was particularly harrowing, claiming many cars over the years (including three Ferrari 512 variants) and several lives, including the legendary John Woolfe in 1969 behind the wheel of a Porsche 917. The circuit has been modified ten more times — 1971, a year when prototypes were averaging over 240 km/h (150 mph), was the last year the classic circuit was used. That year, an Armco barrier was added to the pit straight to separate the track from the pits. In 1972, the race track was considerably revamped, at a cost of 300 million francs, with modification of the pit area and the first and final straights, the addition of the quick Porsche curves bypassing "Maison Blanche", the signalling area being moved to the exit of the slow Mulsanne corner, and the track being resurfaced.

Speed record
In 1988, Team WM Peugeot were well aware of their slim chance of winning the 24-hour endurance race outright, but they knew that their Welter Racing designed car had exceptional straight line aerodynamics. Thus they nicknamed their 1988 entry "Project 400" (aiming to be the first car to achieve a speed of 400 km/h (250 mph) on the famous straight), although the official team entry was named WM Secateva.
Roger Dorchy and Claude Haldi would be the drivers of car 51 while Pascal Pessiot and Jean-Daniel Raulet would drive the team's other car (#52). The latter lasted only 22 laps, and car 51 went into the pits around 17:00 in the afternoon with engine problems. After spending 3.5 hours in the pits, the team had the car back on the track and they decided to go for it. The plan worked: with Roger Dorchy behind the wheel the WM P87 achieved the speed of 407 km/h (253 mph). The Peugeot retired shortly after that (on lap 59) with an overheating engine. By then it had outlasted two other Group C1 entrants.
Since Peugeot had just launched its new model 405, the team agreed to advertise the new record as "405". This has led to many people mistakenly stating the record as only 405 km/h (252 mph), but Dorchy's best run down the Mulsanne straight was clocked at 407 km/h (253 mph).
Bugatti Circuit
Bugatti Circuit is a 4.185 km (2.600 mi) permanent race track located within Circuit des 24 Heures, constructed in 1965 and named after Ettore Bugatti. The circuit uses a part of the larger circuit and a separate, purpose-built section. The sections of track on the Bugatti Circuit that are on the Circuit des 24 Heures include the Ford Chicane at the end of the lap, the pit complex, and the straight where the Dunlop Tyres bridge is located. At this point in the overlapping section of the tracks there is a left-right sweep that was added for motorcycle safety in 2002. Vehicles turning to the left continue onto the Circuit des 24 Heures, toward Tertre Rouge and Mulsanne, vehicles turning to the right at La Chapelle will continue the Bugatti Circuit. The infield section features Garage Vert, a back straight, the 'S' du Garage Bleu, and Raccordement, which joins back at the Ford chicane.
The track was home base for Pescarolo Sport, founded by famous French driver Henri Pescarolo. The circuit currently hosts the 24 Hours of Le Mans motorcycle race, and a round of the MotoGP Championship. The circuit also holds French motor club races and in the past has hosted rounds of the International Formula 3000 Championship and DTM (German Touring Car series).
In addition to motor racing, it is the venue for the 24 rollers, a 24h race on inline skates or quads.
The Bugatti Circuit was used for the 1967 French Grand Prix, though it would prove to be the only time the Formula One World Championship would use the circuit, and is the current host of the French motorcycle Grand Prix. It also forms the final round of the FIA European Truck Racing Championship, and was part of the World Series by Renault and 1988 Superbike World Championship seasons.

Weather and climate
Météo France runs a weather station in Le Mans, which exhibits an oceanic climate (Köppen Cfb). With both the 24-hour races and the French MotoGP round being run before the peak of summer, high-profile races often have cool temperatures both in terms of ambient and track conditions with rainfall being a potential factor. Although nights cool off, sometimes into the single digits, during the 24-hour car race, air frosts have never been recorded in June. The weather station is located at the local airport just a few hundred metres from the main grandstand and pit lane of the circuit.
