The Trabant
The iconic East German car dominated the roads of communist Central Europe for decades. The Trabant was made out of resin and cotton waste, had a two-stroke engine and its design remained virtually unchanged for thirty years. Johannes Dell has been hearing from legendary German designer Karl Clauss Dietel who worked for years to make improvements to the Trabant - but his innovations were never implemented.
