Mercedes C111 Concept
Although never a production model, the Mercedes C111 was one of the most famous wedge-shaped cars that debuted in the early â70s. They designed this orange classic as a rolling test laboratory for different engine technologies and aerodynamic research.
Aside from the Gullwing doors, they equipped the C111 Concept with various prototype engines including some Wankel rotary units as well as a few high-performance diesels. There was even a V8-powered version, as well.
