  • Practice, Performance and Preparation Paramount for GTP, GTD PRO Competitors in Detroit

DAYTONA BEACH, Fla. – The IMSA WeatherTech SportsCar Championship schedule is nothing if not diverse. The second weekend in May found competitors tackling California’s flowing and bucolic WeatherTech Raceway Laguna Seca road course. Now the final weekend in the merry month of May finds competitors in Michigan taking to the confined, urban streets of the Chevrolet Detroit Sports Car Classic.

If NASCAR and IndyCar have their oval “bull rings” in Martinsville Speedway and Iowa Speedway, respectively, then IMSA’s version of a street course bull ring is the 1.654-mile, nine-turn Motown circuit where paint is often traded during overtakes and the omni-present concrete walls await the slightest mistake from the field of 22 cars, split 11 apiece between Grand Touring Prototypes (GTP) and Grand Touring Daytona Pro (GTD PRO).

LONG BEACH, Calif. – After opening the season with the 36 Hours of Florida (aka the Rolex 24 At Daytona and the Mobil 1 Twelve Hours of Sebring), the 2025 IMSA WeatherTech SportsCar Championship changed things up with the 100 minutes of Southern California (aka the Acura Grand Prix of Long Beach).

Not only was the sprint race a fraction of the length of either of the first two events, the competition was pared down from four classes – Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD) – to two classes: GTP and GTD.

IMSA Insider – In And Out: Will Short Stop Strategically Pay Off Again in Long Beach?

DAYTONA BEACH, Fla. – The IMSA WeatherTech SportsCar Championship has a long, memorable history of racing in the streets, ranging from Miami to Del Mar, San Antonio to Detroit, Nova Scotia to Australia. Bicentennial Park’s streets played host to a two-time Formula 1 World Champion coming out of retirement to race in 1983 in IMSA’s Grand Prix of Miami, setting the stage for a glorious second act to his legendary career. You may have heard of him: Emerson Fittipaldi. And it was Scotland’s Allan McNish (driving with a strained back he injured whilst stepping out of kilt during a pre-race photo shoot) who teamed with Rinaldo “Dindo” Capello and Brad Jones to win IMSA’s first and only race Down Under on the streets of Adelaide.
