IMSA WeatherTech is an endurance sportscar championship running GTP hybrid prototypes, GT3-based cars in two classes, and LMP2 prototypes across four classes. The field is established professional, led by drivers including Alex Palou, Pascal Wehrlein and Kyle Kirkwood; the top two classes field predominantly Platinum and Gold-rated drivers, while the lower classes include a broader amateur and semi-professional base. Drivers arrive from a range of sources including single-seater series and lower endurance championships, with particular strength drawn from Formula 3 Macau and the FIA GT Championship. The series functions as both a destination for established professionals and a step upward from feeder endurance championships; drivers typically move on to either specialised endurance events or remaining within the professional sportscar ladder.
