IMSA at Road America: Another Pratt Miller Podium Proves Corvette Racing Is The One To Beat

Nestled in the rolling glacial hills of Elkhart Lake, Wisconsin, Road America provided a beautifully scenic yet brutal stage for the Motul SportsCar Endurance Grand Prix at Road America. This weekend, the iconic 4.048-mile, 14-turn circuit truly tested the limits of the Corvette Z06 GT3.R platform. Drivers fought through the high-speed commitment required at the Kink, the technical precision of the Carousel, and the sheer power needed to climb the massive front-stretch hill. Navigating a grueling six-hour endurance format—a first for IMSA at Road America—requires an intricate setup balancing maximum aerodynamic efficiency with structural durability to handle the track’s punishing curb strikes.

The weekend’s action only solidified the overwhelming global dominance shared across Chevrolet’s customer and factory-supported programs. On the global stage, the customer-led FIA WEC TF Sport team has put together a formidable season, locking down an impressive haul of three total podiums (including two P1 victories and a P2 finish), highlighted by Jonny Edgar leading the LMGT3 Drivers’ Championship. Meanwhile, the factory-supported Corvette Racing by Pratt Miller Motorsports outfit continues to assert its presence in IMSA. Coming out of Wisconsin, the No. 4 Corvette duo of Nicky Catsburg and Tommy Milner fought their way to a hard-earned 3rd-place finish, securing their third podium of the season and closing to within just 15 points of the lead in the GTD PRO Drivers’ Championship, while simultaneously expanding Chevrolet’s cushion at the top of the Manufacturers’ standings. Added to the single podium already claimed by the sister No. 3 Corvette on the streets of Detroit, the Z06 GT3.R platform has proven to be a championship-caliber weapon on both sides of the Atlantic.
