ACO and LMEM Implement Unified Naming and Color System in Endurance Racing
The Automobile Club de l’Ouest (ACO) and Le Mans Endurance Management (LMEM) have announced the introduction of a standardized naming and color system across endurance racing championships. This initiative aims to enhance recognition for spectators, media, and fans by enabling immediate identification of race classes.
The new structure clearly delineates Pro/Am line-ups, which must include at least one Bronze-rated driver according to FIA Driver Categorisation, while categories labeled as “Pro” will not have this driver requirement. Additionally, each category will be assigned a specific color consistent across all ACO and LMEM competitions.
Pierre Fillon, ACO President, emphasized, “Le Mans has always been several races in one. Our role is to make each of them easy to follow… A shared language of names and colours serves exactly that purpose.”
Category Changes
LMP2
- The existing LMP2 category becomes LMP2 Pro and will adopt navy blue, while the LMP2 Pro/Am category transitions to LMP2 and will be colored light blue. The Asian Le Mans Series retains its LMP2 name with light blue designations, continuing the statistical records from corresponding former categories.
LMP3
- In the Michelin Le Mans Cup, LMP3 will be rebranded as LMP3 Pro, maintaining its gold color. The LMP3 Pro/Am designation will simply be LMP3 with orange replacing the previous purple. The same naming and color structure will apply in the Asian Le Mans Cup and European Le Mans Series.
GT3
- The GT3 category will uniformly adopt green, aligning with LMGT3 classifications in the FIA World Endurance Championship and the European Le Mans Series, establishing a singular identity across all platforms.
The changes come into effect immediately, with the Asian Le Mans Series set to implement these updates at its opening weekend at Paul Ricard.
