IMSA WeatherTech SportsCar Championship will conclude at Michelin Raceway Road Atlanta with the 29th Motul Petit Le Mans, a 10-hour finale featuring 54 entries and multiple title-deciding storylines on Saturday.

The lead GTP class fields 11 cars. Jack Aitken spearheads the #31 Cadillac Whelen V-Series.R, while Laurin Heinrich returns to Porsche Penske’s #7 963 for the decider.

Acura Meyer Shank Racing contests its final IMSA GTP race, targeting a repeat of its 2023 exit win. The program’s swansong adds emotional weight to the championship picture.

Endurance Cup specialists bolster several lineups. Porsche Penske adds Matt Campbell and Laurens Vanthoor, Cadillac brings Frederik Vesti, and Acura MSR enlists IndyCar champions Scott Dixon and Álex Palou.

Strategically, GTP hinges on traffic management and stint discipline. Caution timing around Road Atlanta’s compressed lap amplifies risk, making third-driver execution decisive across night-running phases.

GTD Pro assembles 14 cars amid transition. Pfaff targets a late surge, while Paul Miller Racing evaluates its post-2026 direction. Driver moves add intrigue and potential setup shifts.

Notably, Sébastien Bourdais moves to DragonSpeed’s #74 Chevrolet Corvette Z06 GT3.R. Mattia Drudi joins Car Blanche Aston Martin, and Mathieu Jaminet replaces Ricardo Feller at Manthey’s #911 Porsche.

Factory talent deepens the grid. Benji Goethe debuts with RLL Team McLaren, and Dan Harper returns to Paul Miller Racing, strengthening pit stop efficiency and long-run tyre consistency projections.

LMP2 attracts 11 entries. Intersport fields Jon Field, Oliver Jarvis, and Max van der Snel. Era Motorsport’s #18 features Naveen Rao, Ferdinand Habsburg, and Jacob Abel after recent team success.

That momentum follows a win for teammates Nick Boulle and Christian Rasmussen, tightening championship arithmetic.

GTD swells to 18 entries, buoyed by Endurance Cup entrants AF Corse, Triarsi Competizione, and Magnus Racing. Changes include Luca Stolz joining Lone Star Racing and Alec Udell at Conquest.

The Stolz addition complements Russell Ward’s established Lone Star programme, strengthening double-stint capacity for the race’s cooler closing hours.

With multi-class overlap acute at Road Atlanta, safety car exposure and pit cycle offsets will likely swing margins. Teams prioritise clean traffic windows and error-free full-service stops.

The green flag waves Saturday morning for 10 hours. Championships, programme finales, and reputations hinge on execution under pressure, with depth across all classes promising relentless pace to the flag.
