Car of the Year in 1967, this disaster had no success guaranteed for the commercial market. Once claimed the world most aerodynamic production road car had terrible issues under the hood.

The company was eventually bought up by the VW/Audi empire. Most of its cars have been fitted with Mazda’s rotatory engines.
