IMSA - Motul Petit Le Mans

The Motul Petit Le Mans stands as the final race of the IMSA WeatherTech SportsCar Championship season. This 10-hour endurance race takes place at Michelin Raceway Road Atlanta in Braselton, Georgia. The event also serves as Round Five of the IMSA Michelin Endurance Cup, a championship within the larger series that tallies points from the season's endurance races.

The Race Weekend

The Motul Petit Le Mans offers four days of on-track competition. The IMSA WeatherTech SportsCar Championship headlines the event with its 10-hour main race. Several support series join the weekend schedule, including the IMSA Michelin Pilot Challenge with the FOX Factory 120 race, the VP Racing SportsCar Challenge, Porsche Carrera Cup North America, and the Whelen Mazda MX-5 Cup presented by Michelin. Each series brings multiple practice sessions, qualifying rounds, and races throughout the multi-day event.

Michelin Raceway Road Atlanta

Michelin Raceway Road Atlanta is a 2.54-mile road course located approximately 35 miles north of downtown Atlanta. The track features 12 turns and sits on 750 park-like acres in Braselton, Georgia. The circuit includes the well-known "esses" between turns three and five, plus a downhill, diving Turn 12. The facility experiences significant elevation changes and high-speed sections, earning it the nickname "roller coaster" among drivers.

The venue includes the Michelin Tower, a five-story building with private suites, hospitality areas, a media center, race control, and a rooftop deck. Families can enjoy concessions and public restrooms throughout the grounds. Children 12 and under receive free admission when accompanied by an adult.

Championship Classes and Competitors

The IMSA WeatherTech SportsCar Championship fields four distinct classes at the Motul Petit Le Mans. Each class competes simultaneously on track, racing for position within their respective categories.

Grand Touring Prototype (GTP)

The GTP class represents the premier category in IMSA racing. This class expects 11 full-season entries, with manufacturers including Acura, Aston Martin, BMW, Cadillac, Lamborghini, and Porsche. The Heart of Racing team plans to field the Aston Martin Valkyrie in this class. These cars feature hybrid powertrains that store kinetic energy from braking for later use. Each manufacturer develops its own internal combustion engine and bodywork.

Le Mans Prototype 2 (LMP2)

The LMP2 class will feature 12 full-season cars from 11 teams. Teams competing include United Autosports USA running two cars, CrowdStrike Racing by APR, Tower Motorsports, TDS Racing, Era Motorsport, Intersport Racing, Inter Europol Competition, Bryan Herta Autosport with PR1/Mathiasen, Team Tonis, Pratt Miller Motorsports, and AO Racing. These cars are closed-cockpit prototypes built by approved constructors.

GT Daytona Pro (GTD Pro) and GT Daytona (GTD)

Both GT classes use cars built to FIA GT3 technical regulations, based on production models. The GTD Pro class expects to field manufacturers such as Aston Martin, BMW, Chevrolet, Ferrari, Ford, Lamborghini, Lexus, Mercedes-AMG, and Porsche. Ferrari, Winward Racing, and Triarsi Competizione will make their GTD Pro debuts. McLaren returns to IMSA in the GTD Pro category.

The GTD class confirms 14 full-season entries, with additional cars joining for endurance rounds like the Motul Petit Le Mans. New or returning teams include Riley, which moved from LMP2, 13 Motorsports formerly known as AWA, and RS1 stepping up from the Michelin Pilot Challenge.

Expected Field Size

IMSA confirms 45 full-season entries for the WeatherTech Championship. The field expands to 54 cars for Michelin Endurance Cup races, which includes the Motul Petit Le Mans. The Heart of Racing team has announced driver lineups for their entries, with Ross Gunn, Roman De Angelis, and Alex Riberas piloting the No. 23 Valkyrie, and Dudu Barrichello, Tom Gamble, and Zacharie Robichon driving the No. 27 Vantage.

Race Format and Technical Details

The Motul Petit Le Mans runs as a timed 10-hour race. Teams manage driver changes, fuel stops, and tire strategy throughout the event. The race continues regardless of how many laps are completed, with the winner determined by distance covered when time expires.

Michelin serves as the official tire supplier for the championship. The series employs a Leader Light System, which uses LED panels on the cars to display their position within their respective classes. This helps spectators track race positions across the four different categories competing simultaneously.

Event History and Significance

Don Panoz founded the Motul Petit Le Mans in 1998 while serving as owner of Road Atlanta. He envisioned bringing the spirit and rules of the 24 Hours of Le Mans to North America. The inaugural race was part of the IMSA GT Championship. The success of this first event led Panoz to establish the American Le Mans Series (ALMS) in 1999, with Petit Le Mans becoming a flagship event.

The race initially covered either 1,000 miles or 10 hours, whichever came first. The format permanently switched to a 10-hour timed race in 2014. The event now holds a position among the "Big Six" endurance races globally, 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 race often serves as the championship decider for the IMSA season. Notable historical moments include the Ferrari 333 SP winning the inaugural race in 1998 and the Porsche 911 RSR achieving an overall victory in rain-soaked conditions in 2015. Rinaldo Capello holds the record for the most overall wins with five victories.

What Makes This Event Unique

The name "Petit Le Mans" means "little Le Mans" in French, directly referencing its inspiration from the famous French 24-hour race. The circuit's dramatic elevation changes challenge drivers from around the world. The original IMSA logo drew inspiration from cars traveling through the famous "Esses" at Road Atlanta.

The event attracts approximately 140,000 racing fans to its park-like setting. The multi-class format creates diverse racing action, with different categories of cars competing simultaneously on track. The 10-hour duration tests both driver endurance and team strategy. Weather conditions can shift throughout the race, adding another variable for teams to manage.

The season finale format means championship titles are often decided during this race. Multiple championships are at stake, including overall season titles and the Michelin Endurance Cup. Teams must balance aggressive racing to gain positions with conservative strategy to ensure they finish the full 10 hours.

The Championship Battle

The Motul Petit Le Mans awards points for both the overall IMSA WeatherTech SportsCar Championship and the IMSA Michelin Endurance Cup. Teams compete across multiple events throughout the season, with this race serving as the final opportunity to score points. The endurance cup specifically rewards performance at longer races, making this 10-hour event crucial for teams focused on that championship.

Each class runs its own championship battle. GTP teams compete for the premier prototype title. LMP2 teams race for honors in their spec-chassis category. GTD Pro and GTD classes each crown their own champions. This multi-championship format means multiple title fights unfold simultaneously on track at Michelin Raceway Road Atlanta.
