Heritage Porsches Lead a 54-Car IMSA Endurance Field at Road America
A 54-car IMSA WeatherTech SportsCar Championship entry list heads to Road America for the six-hour Motul SportsCar Endurance Grand Prix, the first Michelin Endurance Cup round at the Wisconsin track, featuring Porsche Penske Motorsport’s heritage liveries and Kevin Estre’s first Road America start since 2014 in a prototype; the field includes late entries and driver changes that push toward the track’s 55-car cap (with pit-lane extensions), plus updates on Pfaff Lamborghini’s Brembo brakes, iRacing activity, and related fan events.
