Buckminster Fuller's Dymaxion car, from 1933, was designed to carry ten people on three wheels. Made of aluminum, it only weighed 1,000 pounds and was intended to get 30-50 miles per gallon.

Ben Discoe became obsessed with the Dymaxion, of which only three were ever built, and dedicated a section of his website towards documenting as much about the car as he could find. With the original patent drawings and several dozen photos of the car in various states of construction, it's a must-click for Fuller fans.
