IMSA 2023 calendar unveiled

The penultimate round of the 2022 IMSA season, Road America is an opportunity to already think about the next exercise. While only the VIR (August 26-28), a round reserved for Grand Touring cars, will remain, and Petit Le Mans (September 28-October 1) as the final meeting, John Doonan, President of IMSA, revealed the program for the next North American Endurance Championship. As a reminder, this vintage will mark the return of the GTP category and the arrival of the LMDhs to replace the current DPi.

The grand debut of new prototypes from Porsche, BMW, Acura and Cadillac will take place at the 24 Hours of Daytona, from January 26 to 29. 11 rounds will be scheduled against 12 in 2021. Mid-Ohio and Detroit will thus not be the part, while Indianapolis, previously announced, will return. Six events will see the five categories (GTP, LM P2, LM P3, GTD Pro, GTD) on track: Daytona, Sebring (March 15-19), Watkins Glen (June 22-25), Road America (August 4-6) , Indianapolis (September 15-17) and Petit Le Mans (October 11-14). In these six rounds, four will make up the Endurance Cup: the 24 Hours of Daytona, the 12 Hours of Sebring, the 6 Hours of the Glen and Petit Le Mans.

IMSA also announced its sustainable commitments. Thus, each GTP car will use a single-source hybrid powertrain, which will reduce fuel consumption by more than 10%. For the internal combustion engine of each car, IMSA’s official fuel supplier, VP Racing Fuels, will supply VP R80 renewable fuel.

Michelin, the official tire supplier of IMSA, has developed a unique new tire for the GTP class, which will have the ability to double stints. This could lead to a reduction in tire usage of up to 25%. Current Michelin WeatherTech Championship racing tires contain almost 30% sustainable raw materials.

The manufacturer also presented a new racing tire containing 53% sustainable raw materials. IMSA and Michelin are working together to explore the introduction of this tire into IMSA competition.
