SEBRING, Fla. — The International Motor Sports Association revealed the 2027 schedule for the IMSA WeatherTech SportsCar Championship, becoming the first major auto racing sanctioning body to announce its schedule for the following season for the third consecutive year.
“Announcing our schedule this early in the year, which has now become our tradition, is a testament to the stability of our events and our promoter relationships, and we are grateful to all of our promoter partners,” said IMSA CEO Ed Bennett. “It also provides an opportunity for everybody involved – from stakeholders and participants to IMSA race fans – to adequately make their plans to attend well in advance. Nearly all of our events have seen year-over-year attendance increases the past few years, so it is conceivable that our strategy of announcing our schedules in March is paying dividends.”
The WeatherTech Championship again features an 11-race season with some subtle changes.
Stability remains the name of the game with the IMSA WeatherTech SportsCar Championship, with all 11 venues that have hosted the series for the past several seasons returning in 2027.
“Each season presents an opportunity to build on IMSA’s incredible momentum, and the 2027 schedule represents the very best of our longstanding partnerships and world‑class venues,” said IMSA President John Doonan. “We are grateful for the continued collaboration with our television partner, NBC Sports, whose support allows us to showcase IMSA’s thrilling, multi‑class racing to race fans everywhere. We also appreciate the cooperation from our fellow sanctioning bodies as we all work together in good faith to minimize date conflicts and create the strongest possible calendar for teams, partners, and fans.
“The 2027 season is especially meaningful as we celebrate several historic milestones: the 75th running of the Mobil 1 Twelve Hours of Sebring, the 70th anniversary of WeatherTech Raceway Laguna Seca, the 65th Rolex 24 At Daytona and the 30th running of Motul Petit Le Mans. These iconic events represent the heart and soul of sports car racing, and we look forward to honoring their legacies with our competitors and passionate fanbase next season.”
The season will start one weekend later than it has traditionally started with the 65th running of the Rolex 24 At Daytona slated for the weekend of January 28-31 on the 3.56-mile Daytona International Speedway circuit. Daytona again kicks off the “36 Hours of Florida,” and will be followed by the milestone 75th running of the Mobil 1 Twelve Hours of Sebring on March 17-20.
Both races again will be part of the five-race IMSA Michelin Endurance Cup season and will include all four classes – Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD).
From there, the series makes its way to California for the annual “West Coast Swing,” featuring the 100-minute Acura Grand Prix of Long Beach on April 16-17 and a two-hour, 40-minute race at WeatherTech Raceway Laguna Seca in Monterey, California on April 30-May 2. Long Beach will feature the GTP and GTD classes, while GTD PRO joins the party in Monterey.
The streets of downtown Detroit again will feature the sights and sounds of GTP and GTD PRO machinery on June 4-5 when the series returns for another 100-minute battle as part of the Chevrolet Detroit Grand Prix. The Sahlen’s Six Hours of The Glen opens the summer portion of the season with the WeatherTech Championship making its annual voyage to New York’s Finger Lakes region for the annual four-class, six-hour clash on June 24-27. Watkins Glen marks the halfway point in the battle for the Michelin Endurance Cup.
Canadian Tire Motorsport Park in Bowmanville, Ontario brings three WeatherTech Championship classes – LMP2, GTD PRO and GTD – north of the border for two hours and 40 minutes of racing on July 9-11. All four classes reunite in Elkhart Lake, Wisconsin for another six-hour battle on the famed, four-mile Road America circuit on July 29-August 1 which marks the penultimate race of the 2027 Michelin Endurance Cup.
Virginia International Raceway in Alton, Virginia hosts its traditional, two-hour, 40-minute battle for the GTD PRO and GTD classes in the Michelin GT Challenge on August 20-22. After a nearly one-month break, all four classes will reunite at Indianapolis Motor Speedway for the two-hour, 40-minute TireRack.com Battle on the Bricks for the second-to-last WeatherTech Championship race of the season on September 17-19.
will set the stage for an epic, 10-hour finale – the 30th Motul Petit Le Mans – at Michelin Raceway Road Atlanta in Braselton, Georgia on October 6-9 to close out both the 2027 WeatherTech Championship and Michelin Endurance Cup seasons.
In addition to unveiling the 2027 WeatherTech Championship schedule, IMSA also unveiled plans to offer expanded sanctioned testing prior to the five IMSA Michelin Endurance Cup events at each of the facilities hosting these events.
