Tucker 48

Only 51 Tucker Torpedos, as they were commonly known, were ever produced due to stock fraud allegations. Despite its limited production, the Tucker 48 is still regarded as an example of American ingenuity. The Tucker Corporation went bankrupt in 1950, two years after the Tucker 48 halted production.

The car’s body “shape shifted” with the opening of its doors, as the fabric exterior stretched around it. We’ll have to wait for the next century until this one’s in driveways.
