Ford Mustang GT3

The Ford Mustang GT3 is a grand tourer racing car built by Ford Racing and Multimatic Motorsports for use in Group GT3 competition. Developed in 2022, the car is based on the seventh-generation Ford Mustang Dark Horse and was formally unveiled as part of the 100th anniversary of the 24 Hours of Le Mans on June 9, 2023, making its competitive debut six months later at the 2024 24 Hours of Daytona. It currently competes in a number of major racing series worldwide, including the Deutsche Tourenwagen Masters, FIA World Endurance Championship, GT World Challenge, and IMSA SportsCar Championship.

Development

In 2022, it was announced that Ford Performance and Multimatic Motorsports would be developing a Group GT3-specification Ford Mustang.
The car is powered by a race-tuned 5.4-liter naturally aspirated Ford Coyote V8 developed in partnership with long-time World Rally Championship factory partner M-Sport. It is equipped with a Bosch MS 6.4 engine control unit, a four-plate AP Racing clutch with a MEGA-line e-clutch actuator, and a 6-speed Xtrac sequential manual. For better weight distribution, the transmission was positioned closer to the rear axle.
The chassis features an FIA-homologated fully-integrated compliant racing roll cage as well as other safety devices. It has Multimatic five-way adjustable DSSV dampers, double wishbone suspension on both axles and Alcon brake discs. It also features quickly replaceable parts to make rapid repairs, although this created issues in the car's first year, when in some cases, the boot lid and diffuser would come loose or detach from the car completely, causing lengthy repairs or retirements from races. Ford was later granted permission by the Fédération Internationale de l'Automobile to implement reliability updates to the car to alleviate the issue.

Ford Mustang GT3 Evo

On November 13, 2025, Ford began testing an 'Evo' kit on the Mustang GT3 at an IMSA-sanctioned test in Daytona International Speedway. Ford detailed the 'Evo' package in a press article on December 17, 2025 highlighting a series of upgrades based on improving overall vehicle dynamics, including dive planes, a revised front splitter and rear diffuser, an updated brakes package from Brembo, and improved suspension.

Teams

Upon its debut, Proton Competition and Multimatic Motorsports were announced as the first teams to run the Mustang GT3, with two-car entries in the FIA World Endurance Championship and the IMSA SportsCar Championship, respectively. Four other teams have since fielded Mustangs in other racing series: Dollahite Racing, Gradient Racing, Haupt Racing Team, and Riley Motorsports.

Competition history

Early in its first year of competition, the Ford Mustang GT3 experienced issues with its boot lid and diffuser as either part would come loose or detach from the car completely during races. The Fédération Internationale de l'Automobile later granted Ford an "erratum fix" to resolve the issue, which Ford believed to have been caused when cars would follow closely, disrupting airflow. The Mustang later achieved its first pole position and podium in any series at the 2024 Michelin GT Challenge at VIR courtesy of Proton Competition's #55 car in the GTD class and Multimatic Motorsports' #64 car in the GTD Pro class, respectively. Proton Competition also secured a podium at the 2024 24 Hours of Le Mans with their #88 car, Ford's first at Le Mans since 2018.
Ford's program expanded in 2025 with Dollahite Racing, Gradient Racing, and Haupt Racing Team fielding Mustangs in ADAC GT Masters, Deutsche Tourenwagen Masters, GT World Challenge, and Nürburgring Langstrecken-Serie. The Mustang would earn its first victory at the 2025 24 Hours of Daytona following a close battle with BMW and Chevrolet in the final hours. It also secured a notable class win at the 2025 24 Hours of Nürburgring, with Haupt Racing Team finishing 1st in SP 9 Pro-Am and 4th overall.
