The IMSA LMP3 class is not to be overlooked with teams who made the hello for Group C and the American Le Mans series in the 80s and 90s, like Andretti Autosport and Riley. The competition is tough as we have counted four different teams who have won the 7 championship races of 2022.

The Grand Touring Prototype (GTP) grid is almost completed: the four manufacturers’ full-time drivers of the IMSA Weathertech Sportscar Championship and the ones who’ll compete in the IMSA Michelin Endurance Cup or solely in the Rolex 24.

Andretti Autosport and Wayne Taylor Racing announced a new, long-term partnership today that will see the championship-caliber teams combine resources to compete in IMSA’s top classes.
