Motul Petit Le Mans

The Motul Petit Le Mans at Michelin Raceway Road Atlanta serves as the season finale for the IMSA WeatherTech SportsCar Championship. This 10-hour endurance race brings together professional teams and drivers from around the world to compete at one of North America's most challenging road courses. The event also represents Round Five of the IMSA Michelin Endurance Cup, a championship dedicated to endurance racing within the larger IMSA series.

Race Format

The Motul Petit Le Mans is a 10-hour timed endurance race. Teams compete for 10 hours straight, with overall and class championships often decided during this season-ending race. The event draws inspiration from the 24 Hours of Le Mans in France, bringing similar rules and competitive spirit to North America. The name "Petit" means "little" in French, referencing the shorter duration compared to the full 24-hour race.

The Circuit

Michelin Raceway Road Atlanta is located in Braselton, Georgia, approximately 35 miles north of Atlanta. The track measures 2.54 miles (4.088 km) in length and features 12 turns. The circuit is known for its natural-terrain layout with significant elevation changes, earning it the description of a "roller coaster" track.

The downhill "Esses" section between turns three and five provides one of the most challenging sequences for drivers. Turn 12 is a fast, diving corner that leads onto the main straight. The facility sits on 750 acres, offering spectators ample viewing opportunities across the property.

Competition Classes

The IMSA WeatherTech SportsCar Championship features four classes that race simultaneously at the Motul Petit Le Mans:

Grand Touring Prototype (GTP)

GTP represents the premier prototype class in IMSA racing. These advanced hybrid-powered cars come from manufacturers including Cadillac, Porsche, Acura, and BMW. This class showcases the latest technology in sports car racing.

Le Mans Prototype 2 (LMP2)

LMP2 serves as the pro-am prototype class, allowing a mix of professional and amateur drivers to compete in purpose-built prototype race cars.

GT Daytona Pro (GTD PRO)

GTD PRO features professional drivers competing in GT3-specification cars. These vehicles are based on production sports cars but modified for racing.

GT Daytona (GTD)

GTD also uses GT3-specification cars but requires a Pro-Am driver lineup, mixing professional and amateur talent.

Race Strategy and Technical Elements

Endurance racing at Michelin Raceway Road Atlanta demands both speed and reliability over 10 hours. Teams typically assign three drivers to each car, rotating throughout the race according to IMSA regulations. Pit stops play a crucial role in race strategy, involving refueling, tire changes, and driver swaps. Teams may also perform brake pad and rotor changes or aerodynamic adjustments during these stops.

The Balance of Performance (BoP) system applies to the GT classes, ensuring competitive racing among different car models from various manufacturers. This system adjusts vehicle specifications to create equal performance potential across different makes and models.

Support Series

The Motul Petit Le Mans weekend includes races from several support series. The IMSA Michelin Pilot Challenge features the FOX Factory 120 race. Porsche Carrera Cup North America, Whelen Mazda MX-5 Cup presented by Michelin, and the IMSA VP Racing SportsCar Challenge also compete during the weekend, providing multiple days of on-track action.

Event History

Road Atlanta owner Don Panoz founded the Petit Le Mans in 1998. He envisioned creating an American endurance race that embodied the rules and spirit of the 24 Hours of Le Mans. The race's success led to the formation of the American Le Mans Series (ALMS) in 1999, where Petit Le Mans became a flagship event.

The race was initially contested over 1,000 miles or 10 hours, whichever came first. In 2014, it permanently became a 10-hour timed race. Since 2014, the event has been part of the IMSA SportsCar Championship, known as the IMSA WeatherTech SportsCar Championship since 2016.

Notable Characteristics

The 10-hour duration means the race transitions from daylight into darkness, adding complexity for drivers who must adapt to changing visibility conditions. The Petit Le Mans holds recognition as one of the "Big Six" endurance motor races worldwide, alongside the 24 Hours of Le Mans, 24 Hours of Daytona, 12 Hours of Sebring, 24 Hours of Nürburgring, and 24 Hours of Spa.

The event maintains a family-friendly atmosphere at Michelin Raceway Road Atlanta. Children 12 and under typically receive free admission when accompanied by an adult. The facility's park-like setting provides a comfortable environment for spectators, and camping is popular during the race weekend. The event attracts thousands of racing fans who come to witness this demanding test of speed, strategy, and endurance.
