The Porsche No. 6 drivers of Team Penske are the defending Hypercar World Endurance Drivers' Champions with Toyota defending the Manufacturer Championship.
From this season onwards, manufacturers will be required to field at least two cars in the Hypercar class to be allowed to participate. The same rule is already enforced in the LMGT3 category.[1] Additionally, in LMGT3 class the Bronze-rated driver will be obligated to take part in Qualifying session, but no longer in Hyperpole session. Furthermore, the maximum grid size for this season has been increased from 37 to 40, to accommodate the increase in entries by Hypercar manufacturers who fielded only one car in the 2024 World Endurance Championship.[2]
Calendar
The calendar was announced on 14 June 2024, during the 2024 24 Hours of Le Mans weekend. The calendar is unchanged from 2024, with the Imola Circuit featuring on the calendar until at least 2028, with the circuit committing to building additional pit garages.[3]
Five years after withdrawing its early commitment to the Hypercar formula, Aston Martin entered the class with a modified, non-hybrid version of its Valkyrie. The car, operated by The Heart of Racing (THOR) and Multimatic, was the first sports prototype by the British brand since the AMR-One LMP1.[4]
Chip Ganassi Racing and General Motors parted ways at the end of 2024, with Porsche customer Jota Sport moving over to run Cadillac's factory programme.[18][8] The American marque doubled up to align with a new rule requiring manufacturers to enter a minimum of two cars.[19]
The LMGT3 category's colour code changed from orange to green, last used by LMGTE Pro in 2022.[31]
French-Swiss team Racing Spirit of Léman, based nearby the namesake lake, made its series debut replacing D'station Racing as the second of Aston Martin's Prodrive-run customers.[23]
In the wake of Lamborghini's full-scale exit from WEC, Iron Lynx partnered up with Mercedes-AMG to field a pair of Mercedes-AMG GT3 Evos. The tie-up marked the German manufacturer's WEC debut, and also Iron Lynx's fourth brand affiliation in as many years.[27]
Iron Dames did not follow its parent team to Mercedes, instead opting to rejoin the Porsche fold with Manthey Racing.[29] Reigning champion Pure Rxcing did not defend its title and switched focus to LMP2.[32]
