The IMSA Sports Car Championship kicks off this weekend with the iconic 24 Hours of Daytona.
Held at Daytona International Speedway, the event claims to be the United States' most prestigious sports car race, putting both drivers and machines to the limit from sunrise to sunset and through the night.
The 24 hour event is run on the 3.56-mile sports car course layout at the historic Daytona circuit, using most of the tri-oval, plus an infield road course.
Given its prestige, big names from the world of motorsport are always keen to get involved in the event, and this year, there just so happens to be plenty of former Formula 1 drivers taking part.
With that said, we thought we'd take a look at which ex-stars are competing, for whom, and in which class.

Unfortunately, no current Formula 1 drivers are taking part in the 24 Hours of Daytona in 2025. However, there are plenty of former drivers taking part, including a driver that was on the grid just last season.
