Transformers: Cars that changed into something quite different

Only 75 were built, but that made this almost a mainstream car compared with the version created in 1960 by another Italian coachbuilder, Zagato. In the 1930s, Auto Union was the umbrella term for four previously separate but now merged German manufacturers, and for a series of tremendously powerful Grand Prix cars. This was basically a rebadged DKW Sonderklasse, but that car’s 896cc three-cylinder two-stroke engine was enlarged to 981cc, a change approximately referred to in the model name.
