IMSA reveals 55-car entry list for Sebring

IMSA has published the entry list for the 74th annual Mobil 1 Twelve Hours of Sebring later this month, featuring 55 cars across all four categories.

Sebring will feature the world racing premiere of the new Lamborghini Temerario GT3, competing in the GTD Pro class with Pfaff Motorsports. The No. 9 Lamborghini’s maiden voyage will be steered by Squadra Corse factory drivers Andrea Caldarelli, Sandy Mitchell, and Franck Perera. This will also be Perera’s first start of the season for Pfaff Motorsports.

All 11 GTP cars returning from the Rolex 24 At Daytona have their regular three-driver endurance crews, including JDC-Miller MotorSports’ 2025-spec Porsche 963. That car has picked up Mustang Sampling as a sponsor, and changed numbers from No. 85 to No. 5, reverting to the number used by JDC-Miller when it began racing in GTP during the 2023 season. The No. 5 plate had previously been worn by the Proton Competition team during 2024 and '25, when Mustang Sampling sponsored its privateer Porsche 963.

JDC-Miller will also enter its No. 79 ORECA 07-Gibson into the 12-car LMP2 field, driven by Gerry Kraut, former Riley LMP2 driver Josh Burdon and former British GT champion Sennan Fielding, who’ll make his IMSA WeatherTech SportsCar Championship debut at Sebring.

Winward Racing will enter its No. 48 Mercedes-AMG GT3 EVO in GTD Pro for the second of its two scheduled races, after a strong result at Daytona. GTD Pro has 13 entries, and the GTD class rounds out the field with 19 cars.

Coming off a second-place finish in class with Magnus Racing, Spencer Pumpelly will join RS1 behind the wheel of the No. 28 Porsche 911 GT3 R, alongside Jan Heylen and Dillon Machavern.
