A group of 12 Audi apprentices has transformed a classic NSU Prinz sports coupé into a stunning electric vehicle (EV) in celebration of the 150th anniversary of the German firm’s factory in Neckarsulm.

The EV, named EP4 after the Prinz 4, features a rear-mounted 236bhp electric motor derived from the 2020 Audi E-tron, with power supplied by a front-mounted battery from the Audi Q7 TFSIe plug-in hybrid. The battery is located under the carbon fiber hood, replacing the Prinz’s fuel tank.

While the car, a 1971 NSU Prinz 4 that had been inactive, underwent substantial modernization, it still retains its original front and rear lights, as well as its distinctive shoulder and roof lines.

Modifications were made to accommodate the new powertrain, which is 207bhp more powerful than the Prinz’s original two-cylinder petrol engine.

The primary modifications were made to enhance cooling. The car features large green intakes at the bottom of the bumper to allow air circulation, with hot air escaping through an opening in the hood. The tailgate can even be partially open to prevent the electric motor from overheating.

In addition, the Audi A1 provided the floorpan, brakes, and axles, while the EP4’s body was substantially widened and fitted with wide wheels and performance tires.

At the back, a bright yellow wing is attached to the roll cage instead of the bodywork. The body itself is coated in Suzuka Grey and Brilliant Black paintwork, Audi’s signature colors, with the number ‘150’ displayed on the doors.
