The 2025 Ford Mustang GTD represents the pinnacle of Ford Performance engineering — and it’s built in a way unlike any Mustang before it. Production began earlier this year, and now we have an inside look at the unique, hybrid manufacturing process shared between Ford’s Flat Rock Assembly Plant in Michigan and Multimatic’s facility in Markham, Ontario.

According to GTD Chief Program Engineer Greg Goodall, the journey begins just like any other Mustang. At Flat Rock, the GTD is assembled to the body-in-white stage, meaning the core frame and main body panels are complete, but components like the fenders, hood, roof, and trunk are left off. At that point, these unfinished Mustangs are shipped to Multimatic, where the transformation truly begins.

Once in Canada, Multimatic removes sections of the body to make room for the GTD’s race-bred underpinnings. The C-pillars are cut to install carbon fiber reinforcements, while the rear seat area and floor are replaced with a flat-bottom structure to accommodate the car’s advanced suspension system. The facility then installs the carbon fiber aero kit, lightweight panels, and structural enhancements that give the GTD its distinctive look and performance edge.

Next comes painting and assembly. The dashboard, sourced from Flat Rock, is installed alongside the 5.2-liter V8 engine, hand-built at the Dearborn Engine Plant. Meanwhile, specialized components such as Brembo carbon-ceramic brakes, Adaptive Spool Valve Dampers, and bespoke electrical systems are added to complete the build.

Each GTD undergoes an extensive inspection and dyno test before delivery to ensure every car performs to Multimatic’s exacting standards. It’s a meticulous process blending craftsmanship, precision, and technology — resulting in a Mustang capable of lapping Germany’s Nürburgring in under seven minutes.

With production ramping up and customer deliveries underway, the Mustang GTD stands as the ultimate expression of Ford’s racing spirit — built by hand, refined by experts, and engineered to dominate both the street and the track.
