Audi EP4: A Futuristic Throwback Crafted by Audi Apprentices
by AutoExpert | 11 July, 2023
An e-tron's electric motor powers the revamped EP4, an impressive transformation of a modest 1970s sedan.
Twelve bright apprentices from Audi have breathed new life into the iconic NSU Prinz 4, electrifying it to celebrate the 150th Anniversary of Audi's site in Neckarsulm, Germany. Christened the EP4, this modern restomod melds the framework of the original 1971 model with a 2020 Audi e-tron's electric motor and a battery from an Audi Q7 TFSI e quattro plug-in hybrid.
Volkswagen Group acquired the original NSU Prinz 4's creator, NSU Motorenwerke, between 1961 and 1973, before merging it with Auto Union to establish Audi.
The creative team, composed of trainees from fields such as mechatronics, vehicle construction mechanics, bodywork, and painting, crafted a stylish homage to the classic model. This isn't the first time Audi has given its apprentices the freedom to innovate, following the RS6 GTO Concept a few years prior.
Originally equipped with a humble two-cylinder engine that eked out nearly 30 horsepower, the revitalized model now boasts an electric motor with a whopping 236 hp. The former gas tank's spot under the hood now houses the battery, while a wide air intake at the front bumper's base and a hood opening ensure the electric components stay cool.
The rear-mounted e-motor receives additional cooling assistance from a tailgate that can be secured in a semi-open position. Despite many electrified restomods retaining the likeness of their original versions, the EP4 boasts significant interior and exterior upgrades.
The authentic 1970s body keeps its signature shoulder and roof lines, and redesigned lights hint at the older design. To accommodate the boosted performance, the chassis and bodywork needed a complete overhaul, calling for contributions from a third contemporary Audi - the A1 hatchback, which donated its floor pan, brakes, and axles. To provide adequate grip, the expanded body was fitted with modern performance tires.
After removing the 1971 model's rust, the team topped off the work with a shiny coat of Suzuka Grey and Brilliant Black. The EP4's sportier look is accentuated by yellow exterior highlights, including a Signal Yellow rear wing. The car's six taillight clusters mirror the NSU Uruguay station wagon, another model recently celebrated by Audi.
Cynthia Huster, an apprentice automotive painter, explained, "We wanted the EP4's performance to be visually stunning from every angle!"
With the help of 3D printing, the EP4, when parked next to the original, exhibits a lower and noticeably wider stance, courtesy of its muscular fenders.
The interior follows a minimalist design, featuring Recaro Podium bucket seats, black-painted surfaces, and a single-board computer with a corresponding screen. The highlight is the dramatic Signal Yellow roll cage.
Apprentice automotive mechanic Dean Scheuffler shared, "We aimed to build a car that was not just speedy and cool-looking but also paid tribute to the site's 150th anniversary."
Xavier Ros, Audi Board Member for Human Resources, praised, "Our apprentices, with their commendable dedication and considerable creativity, have crafted an impressive car. They can take immense pride in the result. Endeavors like these signify a bright future for our company, driven by our young talent."
