IMSA WeatherTech SportsCar Championship

The IMSA WeatherTech SportsCar Championship is the flagship series of the International Motor Sports Association (IMSA).

The WeatherTech Championship features four classes of racing split between two prototype classes: Daytona Prototype international (DPi) and LMP2, and two GT classes: GT Le Mans (GTLM) and GT Daytona (GTD). The GT Le Mans class is open to any tire manufacturer, while Michelin is the exclusive provider for DPi, LMP2 and GTD. DPi and GTLM generally feature all-professional lineups while LMP2 and GTD require a gentleman driver within their lineups.

The series runs 12 events per season in the United States and Canada, although not every class races at every event. Additionally, some WeatherTech Championship teams also have the opportunity to race at the 24 Hours of Le Mans in June.

Examples of prototype cars include the Cadillac, Acura and Mazda DPis. Examples of GT cars include the Corvette C8.R, Porsche 911 RSR-19, BMW M8 GTE, Acura NSX GT3, Lamborghini Huracán GT3 and more.

Teams run with at least two drivers and for the four endurance races, the Michelin Endurance Cup, can add a third and/or fourth driver. The Michelin Endurance Cup is a “championship within a championship” that features four races that include 52 hours of racing. These races are the Rolex 24 At Daytona, Mobil 1 Twelve Hours of Sebring, Sahlen’s Six Hours of The Glen and Motul Petit Le Mans (10 hours).

IMSA MICHELIN Pilot Challenge

The IMSA MICHELIN Pilot Challenge is one of IMSA’s two Challenge series, which serve as a ladder and support series to the WeatherTech Championship.

Michelin serves as both the Official Tire and title sponsor of the MICHELIN Pilot Challenge. The naming convention for this series refers to the MICHELIN® Pilot® line of tires.

In the MICHELIN Pilot Challenge, there are two classes of production-based cars: GS, which features GT4-specification cars, and TCR, which features TCR specification cars.

This series runs 10 events per season in the United States and Canada. Races are predominately two hours, although there are two four-hour endurance races during the season.

Examples of GS cars include the Ford Mustang GT4, Chevrolet Camaro GT4.R, BMW M4, Audi R8 GT4 and Mercedes-AMG GT4. Examples of TCR cars include the Audi RS3 LMS TCR, Honda Civic Type R and Hyundai Veloster N TCR.

Teams can run two drivers in the two-hour races and up to three drivers in the four-hour races. The series features a mix of professional and gentlemen drivers.

IMSA Prototype Challenge

The IMSA Prototype Challenge is one of IMSA’s two Challenge series, which serve as a ladder and support series to the WeatherTech Championship. Michelin is the Official Tire of the Prototype Challenge series, which features entry-level prototype racing on IMSA race weekends.

This series runs six events per season. Races are predominately one hour, 45 minutes, although there are two three-hour endurance races during the season.

There is a single class in the Prototype Challenge, LMP3. There are six homologated chassis constructors for the class and a single spec engine.

The six chassis constructors for PC are Ligier, Norma, Adess, Ave-Riley, Ginetta and Dome.

Teams run two drivers in the one-hour, 45-minute races and up to three drivers in the three-hour races.

The series features a mix of professional and gentlemen drivers.

Michelin Endurance Cup

The Michelin Endurance Cup comprises the four longest races of the IMSA WeatherTech SportsCar Championship year and features four races with distinct histories in sports car racing.

The Rolex 24 At Daytona opens the season for both the Michelin Endurance Cup and overall WeatherTech Championship. 

IMSA has issued updates to its 2020 schedule. The season generally concludes at Michelin Raceway Road Atlanta with the 10-hour Motul Petit Le Mans in October.

However in 2020, two endurance races have new dates. Watkins Glen International plays host to the Sahlen’s Six Hours of The Glen in early October. Then Sebring’s former military base plays host to the grueling Mobil 1 Twelve Hours of Sebring to end the season in November, rather than in its traditional March date.

The Michelin Endurance Cup comprises 52 hours of racing. Points are awarded at different intervals within each Michelin Endurance Cup race.

Driver, team and manufacturer champions in the Michelin Endurance Cup are crowned at the season finale.

Porsche Carrera Cup North America

The Porsche Carrera Cup launched in North America in 2021. This series features drivers racing in Porsche 911 GT3 Cup cars — all on MICHELIN® tires. The grid is comprised of approximately 30 drivers in three different classes (Pro, Pro-AM, and Pro-AM 991). The Carrera Cup North America is the top single-make platform for Porsche Motorsport in North America, giving grassroot racers a path to the IMSA WeatherTech SportsCar Championship. 

The series puts an emphasis on parity between cars to put the driver’s talent in the spotlight. The 2021 season features races at seven different tracks in the U.S.A.
