Opel GTW Geneve Concept, 1975
Opel revealed a beautifully streamlined two-seater in Geneva in 1975, the "Genève". Engineered to take a Wankel-type rotary engine, its original name was "GT/W" ("W" for Wankel). However, GM dropped its Wankel development program before the car was completed. Opel Design renamed it and exhibited its fiberglass mock-up as an eye-catcher at the show.
