From the late 1990s until 2013, top-level sports car racing in North America was split between the high-techAmerican Le Mans Seriesand the low-costRolex Sports Car Series.These two series were merged in 2014 to form theUnited SportsCar Championship,[1]which was subsequently renamed as the IMSA SportsCar Championship in 2016.Rolex SA'sTudorbrand was the title sponsor of the championship in 2014 and 2015,[2]andWeatherTechhas served as title sponsor since 2016.[3]
The season begins with its premier race, theRolex 24 at Daytona,the last weekend of January and ends with thePetit Le Mans,another North American Endurance Cup race, in early October.
