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.

Analytics Rule; Three First-Timers; A Man For All Seasons (and Classes)

By David Phillips

DAYTONA BEACH, Fla. – IMSA’s lightning-fast, exotic Grand Touring Prototype (GTP) entries from Acura, Aston Martin, BMW, Cadillac, Lamborghini and Porsche bring unquestioned prestige, high-tech, speed and glamour to the WeatherTech SportsCar Championship.

But as Sunday’s Chevrolet Grand Prix at Canadian Tire Motorsport Park demonstrated, the WeatherTech Championship’s other three classes of Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD) can put on one heckuva show when left to their own devices.

DAYTONA BEACH, Fla. – For nearly a decade, two IMSA Michelin Pilot Challenge races run an additional two hours beyond the standard-length of two hours, but pack a similar punch of parity and picture-perfect finishes. Daytona International Speedway has hosted the most, with its BMW M Endurance Challenge race running to four hours every year since 2017, while Watkins Glen International, Michelin Raceway Road Atlanta, Road America, Indianapolis Motor Speedway and Mid-Ohio Sports Car Course have alternated the second.

IMSA Riding New Wave of Emerging GTP Talents

DAYTONA BEACH, Fla. – Every “era” of sports car racing has its iconic performers. In IMSA’s more than 50-year history, that’s broken down by top-class periods of who’s starred in prototypes.

With the reborn Grand Touring Prototype (GTP) class now three years into the formula, there’s a pattern of stars starting to emerge. There are long-time prototype drivers who raced in the previous Daytona Prototype international (DPi) and Daytona Prototype and/or Le Mans Prototype 2 (LMP2) iterations before GTP competing alongside those whose main top-class experience is focused on GTP.

First To The Finish: Docuseries Follows 3 Women Taking On The MX-5 Cup

By Jenn Nelson, Forbes

Motorsports is one of the toughest sports to break into. It’s expensive, demanding, and requires unwavering dedication. From the cost of racing cars, tires, and fuel to training, track access, and travel, the financial barrier is huge.
