A total of 43 cars will contest Motul Petit Le Mans, the final round of the IMSA WeatherTech Sportscar Championship.
The field is split into seven cars in DPi, five in LMP2, ten in LMP3, six in GTLM and fifteen in GTD.
In DPi, the #48 Ally Cadillac DPi-VR returns for the final endurance round of the season as Jimmie Johnson shares the car with Kamui Kobayashi and Simon Pagenaud.
Apart from a previously confirmed change at Meyer Shank Racing with Helio Castroneves in place of Olivier Pla, the DPi field remains unchanged.
The LMP2 field has been boosted by the return of United Autosports’ #22 ORECA 07-Gibson for Jim McGuire, Wayne Boyd and Guy Smith.
The LMP3 grid has grown to a record ten cars with the return of class entries for the likes of United Autosports and WIN Autosport. FastMD Racing has also confirmed its line-up for its series debut, with Todd Archer and Max Hanratty joining James Vance.
Several seats in the class are yet to be confirmed, including at Forty7 Motorsports and Performance Tech Motorsports.
In GTLM, WeatherTech Racing will field a second Porsche 911 RSR-19. The #97 car will likely be driven by a full factory Porsche line-up, but the exact identities of the drivers are unknown.
The two Porsches join the two-car efforts from Corvette and BMW for the final race of the GTLM class in IMSA.
In GTD, Inception Racing will make their championship debut with a single McLaren 720S GT3 for Brendan Trexler, Ollie Millroy and Ben Barnicoat.
Winward Racing, winners of the class at the season-opening Rolex 24 at Daytona, also return with their #57 Mercedes-AMG GT3 Evo for Russell Ward, Philip Ellis and Maro Engel.
