Ford Uses On-Site 3D Printing to Boost Mustang GTD Performance

Ford has taken a major step forward in automotive performance with the launch of the 2025 Mustang GTD. The track-focused supercar, equipped with a supercharged 5.2L V8 and advanced carbon fiber bodywork, achieved a stunning 6:52.072 lap at Germany’s Nürburgring, beating every Ferrari on the circuit. The secret behind this leap in performance? Tiny 3D-printed “hood flicks” that were developed and installed during testing at the track.

The hood flicks, small raised pieces positioned around the vents on the car’s hood, subtly reshaped airflow to increase front-end downforce without adding drag. Chief Program Engineer Greg Goodall explained that these parts allowed the GTD to reach sub-seven-minute lap times, something that would have been very difficult without the on-the-fly 3D printing. The design process for the hood flicks was remarkably fast, with eight iterations tested in just a couple of weeks.

The use of 3D printing allowed Ford engineers to experiment with complex aerodynamic tweaks far later in development than would have been possible using traditional manufacturing. “We were able to design and test these parts at the track itself, which saved valuable time and let us optimize performance directly under real-world conditions,” said Goodall. The result is a car that blends raw American power with precision engineering and modern additive manufacturing.
