Audi‘s Neckarsulm factory in Germany is celebrating its 150th anniversary this year, and the automaker has decided to commemorate the occasion in a unique way. The factory, which currently produces the A6 and A8 sedans, has a rich history that dates back to its days as the property of NSU, a renowned brand that manufactured bicycles, motorcycles, and cars. NSU was once the largest motorcycle manufacturer in the world and later introduced the first-ever passenger car with a Wankel engine. Despite its significance, NSU was a relatively small company compared to other German car brands, leading to its acquisition by Volkswagen in 1969.

To pay homage to NSU and celebrate the factory’s milestone, Audi has chosen to resurrect and modernize one of the last NSU models ever produced—the NSU Prinz 4. The selected vehicle is a 1971 Prinz 4L, a compact two-door sedan powered by a rear-mounted 598 cc air-cooled two-cylinder engine. However, Audi’s modernized version of the Prinz 4L has undergone a remarkable transformation, thanks to a team of 12 trainees who were entrusted with electrifying the classic car.

Audi EP4

The trainees replaced the original engine with a powerful 240 hp electric motor sourced from a 2020 Audi e-tron. The front hood’s traditional fuel tank was removed and replaced with a high-voltage battery pack from the plug-in hybrid Audi Q7 TFSI e quattro. The car’s underbelly was replaced with a modified floor pan from an Audi A1, complete with brakes and axles. The body of the vehicle was extensively modified and widened to ensure a perfect fit. Additionally, a large rear spoiler was bolted directly to the roll cage, making it stand out even more.

Named the EP4, short for “Electric Prinz 4,” the car received a striking paint job in Suzuka Grey and Brilliant Black. The rear wing was given a splash of Signal Yellow, adding a touch of vibrancy to the overall design. Inside, the modernized Prinz 4L features a minimalist approach with a single-board computer and corresponding screen serving as instruments and a display. Recaro Podium bucket seats provide comfortable seating, and a Signal Yellow roll cage enhances safety.

Timo Engler, Head of Training Vehicle Technology/Logistics, expressed his satisfaction with the project, stating that it allowed the apprentices to explore different techniques and materials, including 3D printing and carbon fibre for the front hood. The EP4 serves as a symbol of Audi’s technological prowess and its ability to merge the past with the future.
