IMSA Insider – BMW Doubles Down at Road America
IMSA: Forte’s Good Karma; “Spike” Stays Hot; BMW’s Double Win
DAYTONA BEACH, Fla. – If the 2026 IMSA WeatherTech SportsCar Championship’s new six-hour endurance race at Road America delivers half the action, entertainment and plot twists of yesterday’s two-hour, 40-minute sprint race, a bevy of spectators and television viewers will have gotten their money’s worth.
The phrase “argy bargy” was on display with more car-to-car contact than you’ll see in a month of Saturday nights at your local short track. But there were some popular podium finishers, championship shakeups aplenty and some emotional victors in the Motul SportsCar Grand Prix.
IMSA Insider: See What’s Brewing at Packed Road America IMSA Weekend
DAYTONA BEACH, Fla. – The IMSA WeatherTech SportsCar Championship’s annual midsummer tour of North America’s iconic road courses continues with a trip to Road America for the Motul SportsCar Grand Prix. Opened in 1955 and celebrating its 70th anniversary in 2025, the 14-turn, 4.048-mile circuit’s basic layout has had minimal design changes albeit several surface changes.
Set an hour north of Milwaukee in Elkhart Lake, Wis., the track has rightly earned the nickname “America’s National Park of Speed.” It’s an apt moniker, one that pays homage to the bucolic nature of the facility’s park-like 640 acres along with the breathtaking character of a track where some of the world’s fastest race cars may top 175 mph three times each lap.

DAYTONA BEACH, Fla. – The lone IMSA WeatherTech SportsCar Championship sprint race featuring all four classes kicks off the stretch run to the finish of the final four race weekends of 2025. The freshly renamed Motul SportsCar Grand Prix at Road America marks the last time, for now, this race runs at the standard length two-hour, 40-minute duration before increasing to six hours in 2026.
The combination of four championship battles all under 100 points, intense racing, fun family atmosphere and great food and beverage options highlight the annual trip to the track frequently known as “America’s National Park of Speed.”

Three Takeaways: IMSA Chevrolet Grand Prix at Canadian Tire Motorsport Park
Analytics Rule; Three First-Timers; A Man For All Seasons (and Classes)
By David Phillips
