The VP Racing Fuels SportsCar Challenge is set to take on a new look for 2026, featuring an all-new championship for its four endurance races: the IMSA Airbnb Endurance Challenge.

This four-race championship will feature LMP3 and BMW M2 machinery competing in two-hour race formats during select USAC race weekends throughout the season.

The endurance calendar will include four marquee venues: Sebring International Raceway (March 6–8), Circuit of the Americas (May 7–9), Virginia International Raceway (June 19–21), and Road America (August 14–16).

“Within the IMSA Airbnb Endurance Challenge, LMP3 and M2 teams may field two drivers per car, with a minimum of one driver rated either Bronze or Silver,” IMSA stated. “A Gold-rated second driver is permitted, while Platinum-rated drivers are prohibited.”

The four endurance races help shape a nine-race calendar for the LMP3 class, which opens next weekend at the Roar Before the 24 at Daytona International Speedway. The BMW M2 class will be featured exclusively during endurance race weekends.

“IMSA has always been about innovation and creating unique experiences for our fans, competitors, and partners,” said IMSA President John Doonan. “The introduction of Airbnb as the entitlement partner for the IMSA Airbnb Endurance Challenge is a perfect example of that spirit. These additional endurance events can serve as a launch pad for teams, mechanics, engineers, and drivers looking to grow within the IMSA platform—hopefully progressing to the IMSA WeatherTech SportsCar Championship in the not-too-distant future.”

As noted, the 2026 VP Racing Fuels SportsCar Challenge season begins next weekend at Daytona, featuring the LMP3 and GSX classes. Although there are no GTDX entries expected at the event, the class—introduced last season—remains a part of the championship.
