The 24h du Mans: Endurance Test of Innovations

Every June, car brands race in the iconic endurance circuit at Le Mans. It is a race where drivers are tested to the limits of their physical and mental capacities, where car companies evaluate the quality of their products and automotive innovations, and where locals come together as a community to organize the 24h du Mans. 

But how did this outlandish idea of an endurance test emerge, and why does it hold such importance in the automotive industry?

The Beginning of the 24 Hours

The year was 1922. The secretary of the Automobile Club de l’Ouest, Georges Durand, met with motorsports journalist Charles Faroux at the Paris Motor Show. Joined by Émile Coquille, an industrialist, they came up with the idea of a 24-hour race, an unprecedented idea in the world of Grand Prix racing. Faroux had a clear motive: his readers wanted to see a confrontation between the industry's biggest brands. Durand had the vision. He wanted a race that tested the reliability and safety of the cars. Finally, Coquille provided financial backing as the representative sponsor of Rudge-Whitworth, a bicycle and motor-wheel manufacturing company. 

The first 24h du Mans took place the year after, on May 26th, 1923. Thirty-three cars, mostly of French production, lined up to complete laps on a 17.2-kilometer (~10.7 miles) track mapped out on the public roads of Le Mans.

The race was suspended during World War II and resumed afterward with the restoration of the circuit and the pits, funded by the government.

Safety in the Laboratory 

One of the unique features of this race was its starting procedure. Drivers would line up on the track while their cars were positioned along the pit walls. When the flag dropped, the drivers would run to their cars before setting off. This led to numerous safety concerns. Some drivers were not properly strapped before driving, while others failed to shut the door securely, leading to accidents and serious injuries, including comas. It was not until the 1970 race that the committee ended this tradition, ensuring that drivers were properly seat-belted before dropping the flag. 

While driving safety is advocated by the automobile club during the race, the 24h du Mans also serves as a laboratory for new automotive innovations that manufacturers want to test under extreme conditions. Many of these innovations are still used in car production today. For example, the disc brakes, which help improve brake efficiency and endurance, made their debut in the 1953 race. 

The Rise of Hybridization 

Amid concerns about the planet and the climate crisis, car manufacturers have already begun to shift from gasoline to more sustainable energy sources to reduce carbon emissions, making the race an ideal testing ground for new ideas. 

The first hybrid engine to appear on the records of 24h du Mans was in 1998. The concept was to design an engine that used an internal combustion engine (an engine that generates energy through burning fuel) and support it with an electric motor. However, the model that used this technology failed to qualify for the race.

It wasn’t until the early 2010s that greater focus was placed on electric vehicles, with an emphasis on hybrid cars as a solution for the transition in energy use. In 2012, Audi entered their model in the race. Their diesel-electric hybrid motor focused on storing energy generated by the electric motor in batteries. That year, Audi claimed victory, and its model became the first hybrid to do so. The years that followed highlighted the success of other hybrid models from other manufacturers, such as Toyota, illustrating to the public the evolution of sustainable vehicles being written at Mans. 

For all car lovers, don’t miss the chance to watch the race and see cutting-edge innovations in action on the Le Mans circuit. This year, the 24h du Mans will start on June 10th and end on the 14th. The start will be given on Saturday, June 13, at 4:00 PM, with the finish on Sunday, June 14, 2026.
