IMSA on Grid Guy

The IMSA WeatherTech SportsCar Championship is North America's premier sportscar series, sanctioned by the International Motor Sports Association. Multiple classes race together on the same track at the same time — the headline GTP prototypes (the LMDh hybrids from Porsche, Cadillac, Acura, BMW and Lamborghini), alongside LMP2, GTD Pro and GTD GT3 cars. The season runs from the Rolex 24 At Daytona in January to Petit Le Mans in October, and cars are shared by two to four drivers per entry.

Three endurance classics anchor the IMSA calendar: the Rolex 24 At Daytona (a round-the-clock January season opener), the 12 Hours of Sebring (March, on a bumpy former WWII airfield), and Petit Le Mans (the 10-hour October finale at Road Atlanta). Together with the standalone Indianapolis road race they make up the Michelin Endurance Cup — IMSA's championship-within-the-championship for the long-distance rounds.

The three race hubs above are live now with verified history, all-time leaders and traditions. Live class-by-class standings, per-round results, qualifying detail, driver pages, and the interactive championship tracker are all part of the sportscar build plan — shipping over the weeks ahead.
