The retro Audi GT50 The concept was introduced to celebrate the German premium brand’s history of five-cylinder engines, which began in 1976 with the Audi 100.
Audi’s first production five-cylinder engine had a displacement of just 2.1 liters and an output of 100 kW. Since then, the five-cylinder arrangement has been used in some of Audi’s most famous models, including the Quattro road and rally car, the RS2 Avant and most recently the TT RS.

While Ford, Volvo and Volkswagen used five-cylinder engines not long ago, these engines have all been replaced by four-cylinder engines.
Audi’s five-cylinder engine and the unique rumble of its 1-2-4-5-3 ignition pattern live on in the 299kW/500Nm 2.5-litre turbocharged engine that powers the latest RS3 and serves as the basis for the GT50 concept.
The only images and details we have about the GT50, which was developed in six months by a team of 14 trainees at Audi’s Neckersulm plant, are ours Agreea German newspaper, and the associated Instagram page.
This is the fifth year that trainees at the Audi Neckersulm plant have developed a concept. To turn the RS3 into the GT50, they removed the donor car’s doors, roof, hood, trunk and cabin.
The GT50’s body is made of fiberglass reinforced plastic (FRP) and the design is inspired by the Audi 90 IMSA GTO and Audi 200 quattro Trans-Am racing cars that successfully competed in the United States in the 1980s and 1990s. The roof of the GT50 comes from an Audi 80 sedan.
In stark contrast to the RS3, the GT50 features a flat surface, sparse detail and dull front and rear sections. Not only does this fit in with the 90s and 200s sedans it’s reminiscent of, but it also makes the concept’s oversized front splitter, large trunk spoiler, rear diffuser and pumped-up wheel arches even more visible.
While the bodywork pays homage to Audi’s American racing cars, the alloy wheels are a nod to the rims fitted to the company’s Le Mans endurance racing cars.
Other track-inspired features include the side exhaust outlets and custom roll cage.
Previous model concepts include the 2023 NSU EP4 and the 2020 RS6 GTO, which formed the basis for the limited-edition RS6 Avant GT introduced in 2024.
