How It Works

The American Le Mans Series combined endurance racing formats with technical regulations modeled after the 24 Hours of Le Mans. Each race tested reliability, fuel efficiency, and team strategy over long distances.

LMP Class: Le Mans Prototypes were high-performance, open-cockpit race cars built for speed and endurance. These vehicles featured advanced aerodynamics and hybrid powertrains in later years.
GT Class: Grand Touring cars were based on production models like the Porsche 911 and Chevrolet Corvette. Modifications were allowed for racing performance and safety.
Endurance Format: Races lasted between 2 and 10 hours, requiring multiple drivers per car and mandatory pit stops for fuel, tires, and driver changes.
ACO Regulations: The Automobile Club de l'Ouest set technical rules for engine size, weight, and aerodynamics to ensure competitive balance across classes.
Scoring System: Points were awarded based on finishing position, with extra points for leading laps and class wins, encouraging aggressive yet strategic racing.
Manufacturer Involvement: Automakers like Audi, Porsche, and BMW invested heavily in factory-backed teams to showcase engineering prowess and promote road car sales.
