The ACO and IMSA, the governing bodies of the 24 Hours of Le Mans and 24 Hours of Daytona respectively, have announced a joint renaming. The bus stop chicane on the Daytona backstretch will be renamed the Le Mans chicane, while the first chicane along the Circuit de la Sarthe’s Mulsanne straight will be named the Daytona chicane. It is a permanent renaming of significant corners at significant tracks, a formal acknowledgement of how significant the upcoming alliance between these two races will be.
The 24 hour races at Le Mans and Daytona share a contentious history. While sports car racing as we know it rose to prominence at Le Mans, Daytona popped up in the 1960s and quickly became both one of the most significant endurance races in the world and the anchor point of a burgeoning American sports car racing scene. Over time, championships with similar rule sets developed from each. At Le Mans, the Group C cars of the World Sports car Championship raced for top honors. At Daytona, it was the similar IMSA GTP class that battled for wins. Both fell apart in the early 90s, but, when an alliance could have greatly benefitted both races, the two races went separate ways entirely.
