IMSA/WEC: Watch Porsche’s 963 LMDh hypercar test at Sebring

Following its world debut in June at the 2022 Goodwood Festival of Speed in the U.K., Porsche’s new race car developed to meet LMDh (Le Mans Daytona hybrid) sports prototype regulations is out testing at Florida’s Sebring International Raceway. The site is where Cadillac also recently tested its own LMDh racer.

Porsche’s LMDh, dubbed the 963, has been testing at various locations since the start of the year, though always in full camouflage gear prior to the June reveal. The first race will be the 2023 24 Hours of Daytona, the opening race of the 2023 IMSA SportsCar Championship.

In the FIA World Endurance Championship, LMDh and LMH cars will race together in the premier Hypercar class, which replaced the LMP1 class in 2021. Balance of Performance rules will be used to ensure an even playing field, and some teams, such as Porsche, plan to contest both series.

Acura, Alpine, Audi (maybe), BMW, and Cadillac are also committed to LMDh, while ByKolles, Ferrari, Glickenhaus, Peugeot, and Toyota are all committed to LMH. Lamborghini also announced in May that it will join the LMDh fold in 2024.
