Series

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: Grand Touring Prototype (GTP), LMP2, LMP3 and two GT classes: GT Daytona Pro (GTD PRO) and GT Daytona (GTD). Michelin is the exclusive provider for GTP, LMP2, LMP3, GTP PRO and GTD. GTP and GTD PRO generally feature all-professional lineups while LMP2, LMP3 and GTD require a amateur driver within their lineups.

IMSA’s new era of GTP is made up of Le Mans Daytona hybrid (LMDh) race cars with hybrid-electrified technology. These machines are eligible to compete against Le Mans Hypercar (LMH) in the FIA World Endurance Cup.

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 Acura, BMW, Cadillac and BMW. Examples of GT cars include the Corvette C8.R GTD, Porsche 911 GT3 R (992), BMW M4 GTE, Acura NSX GT3, Lamborghini Huracán GT3 EVO2 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).

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 11 events in 2023 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, Aston Martin Vantage GT4 and Mercedes-AMG GT GT4. Examples of TCR cars include the Audi RS3 LMS TCR, Honda Civic FK7 TCR and Hyundai Elantra 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 amateur drivers.

The IMSA VP Racing SportsCar 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 VP Racing SportsCar Challenge, which features GT4 and LMP3 cars on IMSA race weekends.

This series runs six events in 2023. There are a pair of 45-minute races at each event with one driver per car.

There are two classes in the VP Racing SportsCar Challenge, P3 and GSX. The P3 class is an entry level, closed cockpit LMP3 prototype. GSX uses race cars built to the international GT4 technical regulations. This class features Ford, Aston Martin, Porsche, Mercedes and Chevrolet.

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. Sebring’s former military base plays host to the grueling Mobil 1 Twelve Hours of Sebring next in March. Then Watkins Glen International plays host to the Sahlen’s Six Hours of The Glen in late June. The season and final round of the endurance cup ends at Michelin Raceway Road Atlanta with the 10-hour Motul Petit Le Mans in October.

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.

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 2023 season features races at eight different tracks in the U.S.A.
