The 61st Rolex 24 Hours at Daytona International Speedway starts at 13:40 ET on Saturday, January 28. Sixty-one cars will take the green flag in America’s biggest sportscar race of the year, which kicks off the IMSA season.
New for 2023 is the GTP class – prototype sportscars from Acura, BMW, Cadillac and Porsche – that feature electrical hybrid systems, as IMSA embraces a new era.
