Sebring International Raceway has announced plans host their 75th running of the Mobil 1 Twelve Hours of Sebring on March 20, 2027, launching a year-long celebration with the unveiling of a commemorative logo.
The logo incorporates two parallel blue racing stripes on a white background—evoking the iconic livery of early 1950s American race cars—positioned behind the Sebring Raceway, IMSA, and Mobil 1 logos, along with a prominent “75” marking the milestone.
The design pays homage to Briggs Cunningham, the American driver and team owner whose white cars with blue stripes dominated the event from 1953 to 1955, helping popularize the scheme despite FIA nationality color rules favoring other hues for international competitors.
The race traces its origins to 1952, when Russian-born engineer Alec Ulmann, inspired by the 24 Hours of Le Mans, staged the inaugural 12-hour endurance event on March 15 at the former Hendricks Field, a deactivated World War II Army Air Corps base in central Florida. The wide concrete runways and existing roads provided an ideal layout for what became a grueling test of man and machine.
The first race drew 32 mostly East Coast entries and proved a success, quickly attracting top European teams. Scuderia Ferrari claimed the first non-American victory in 1956, sweeping the top two positions in its debut. By 1959, Sebring’s prestige led to hosting the United States’ first Formula One Grand Prix on Dec. 12, won by Bruce McLaren.
The event has run annually on the third weekend of March—except in 1974 due to the global energy crisis—and is recognized as the birthplace of American endurance racing. It forms one leg of the unofficial “triple crown” of sports car endurance events, alongside the Rolex 24 At Daytona and the 24 Hours of Le Mans.
Sebring has crowned legends including Juan Manuel Fangio, Stirling Moss, Phil Hill, Dan Gurney, Ken Miles, Mario Andretti, Jacky Ickx, Hurley Haywood, A.J. Foyt, and record six-time winner Tom Kristensen.
To mark the anniversary, the raceway unveiled “The Class of 75,” a curated list of 75 standout drivers from the race’s history. Selected by journalists, racing officials, historians, experts, and former competitors, the honorees will be revealed in groups throughout the year. Those attending the 2027 race will collectively serve as grand marshals.
Additional plans include displaying historic winning cars from each decade, starting with the restored No. 9 Frazer Nash Le Mans Replica—the 1952 victor—on loan from the Simeone Foundation Automotive Museum in Philadelphia.
Fans at this weekend’s 74th Mobil 1 Twelve Hours of Sebring (March 21, 2026) can purchase official 2027 commemorative posters at on-site merchandise locations, with each 2026 poster sale including access to buy the 2027 version.
The announcement comes as the raceway continues its long partnership with Mobil 1, which has titled the event for decades.
