Unveiled at the 1967 Frankfurt Motor Show, the NSU Ro 80 was awarded European Car of the Year for 1968 — the first rotary-engined production car to receive the honour. Claus Luthe designed a four-door fastback saloon with a drag coefficient of 0.355, a figure that mainstream manufacturers would not routinely achieve until the mid-1980s. The twin-rotor Wankel engine produced 115 PS but suffered from chronic reliability issues that tarnished the model's reputation and ultimately contributed to NSU's absorption by Audi in 1977. Heritage Icons renders the midnight-blue Ro 80 in overhead plan view with four callout annotations marking the engineering specifics — rotary engine, aerodynamic Cd, drivetrain layout, and production dates.
