The 2023 NSU EP4 Concept was a one-off electric restomod created by Audi apprentices to celebrate the 150th anniversary of the Neckarsulm factory (originally NSU was a knitting machine manufacturer). It reimagines a rear-engined 1971 NSU Prinz 4 as a 240 hp racing EV, combining classic 70s styling with an Audi e-tron motor, a 3D-printed body kit, and a race-spec interior.
