How 3D-printed aero helped the 2025 Ford Mustang GTD hit 6:52 at the Nürburgring

The 2025 Ford Mustang GTD has officially joined the ranks of the world’s quickest production cars. At the Nürburgring it set a 6:52.072 lap, six seconds quicker than the Ferrari 296 GTB and only three seconds off the Porsche 911 GT3 RS. Yet the surprise wasn’t the headline 815 hp, but how 3D printing changed the game.

During testing, Ford engineers realized the car needed more front-axle downforce. Right there at the track they started printing fresh parts—tiny hood flicks, small protrusions beside the hood vents. After several iterations and a check in the Detroit wind tunnel, that tweak proved decisive: it kept the 352 km/h top speed intact while making the car calmer and more planted in corners. It’s the kind of marginal gain that separates a merely fast car from one that feels truly sorted.

Before that, the Mustang GTD already produced more than 600 kg of downforce at 250 km/h, but this micro-part delivered the crucial bump. Without it, cracking the seven-minute barrier would have remained on a knife edge.

In the end, the Mustang GTD landed in the Nürburgring’s top ten. For a model known more for charisma than lap charts, that’s a real breakthrough. An American muscle car stepping onto European supercar turf shows how brute force, paired with innovations like active aerodynamics and 3D printing, can be transformative.
