ELMS LMGTE and ALMS GT teams earning automatic entries were allowed to use them in LMGTE Am only.

Teams earning automatic entries in LMP2 were allowed to change their cars from the previous year. Three participants from the IMSA SportsCar Championship (WTSC) were chosen by the ACO as automatic entries, regardless of performance or category. The second-place finishers in the 2022 ELMS in LMP2 and LMGTE championships also received an automatic invitation. Teams which won championships in the European Le Mans Series (ELMS), Asian Le Mans Series (ALMS) and the Michelin Le Mans Cup (MLMC), received automatic entry invitations. The Cadillac V-Series.R and Porsche 963 (pictured at Daytona) are both set to make their 24 Hours of Le Mans debut in 2023.
