2023 FIA World Endurance Championship

The 2023 FIA World Endurance Championship was the eleventh season of the FIA World Endurance Championship, an auto racing series organised by the Fédération Internationale de l'Automobile (FIA) and the Automobile Club de l'Ouest (ACO). The series was open to prototype and grand tourer-style racing cars divided into three categories. World Championship titles were awarded to the leading drivers in both the prototype and grand tourer divisions and to the leading manufacturer in prototype division.

It was the first season in which LMDh (Le Mans Daytona h) entries were allowed to compete in the Hypercar category for championship points alongside LMH (Le Mans Hypercar) entries, after being permitted on a race-by-race basis in 2022. Upon the discontinuation of LMGTE Pro, LMGTE Am remained as the sole GT class, although it would be replaced by LMGT3 the following season. After being introduced for the 2021 season the LMP2 Pro-Am Cup was also dropped. This as well would also be the last season in the FIA WEC for the LMP2 Class with LMP2 to be removed for the next year's season in the year 2024 due to demand in grid numbers for the Hypercar and the incoming GT3-Spec based LMGT3 class replacing LMGTE Am reaching the maximum number of full season entries.

The No. 23 United Autosports car of Tom Blomqvist dominated the early stages of the race in LMP2. Hometown heroes Team WRT (running Nos. 31 and 41) both battled for supremacy, but the No. 41 of Rui Andrade, Robert Kubica and Louis Deletraz saw the chequered flag first. The team managed to pass the No. 23 United Autosport with 15 minutes remaining. The No. 63 Prema Racing was also in the running, but had to serve a 3-minute stop-and-go penalty. The penalty, for not respecting safety car procedures, was served with 30 minutes remaining, putting them out of contention.

The No. 33 Corvette and No. 25 Aston Martin finished inline astern in second and third places, respectively. Wadoux became the first female driver to win a race in the World Endurance Championship.
