Probably one of the oddest-looking cars of all time, the Isetta is a front-door, rear-engine subcompact that was built by one of the world's leading upscale carmakers. What automaker built it?

Right!

BMW. That's all I've got to say about that.

Who'd a thought it?

The Isetta is an Italian-designed, single-cylinder microcar built under license in a number of different countries. In 1955, the BMW-built Isetta achieved a record 78 miles on a single gallon of gasoline.
