The Dymaxion car was a concept car designed by U.S. inventor and architect Buckminster Fuller in 1933. The word Dymaxion is a brand name that Fuller gave to several of his inventions, to emphasize that he considered them part of a more general project to improve humanity's living conditions. The car had a fuel efficiency of 30 miles per US gallon (7.8 L/100 km; 36 mpg-imp). It could transport 11 passengers. While Fuller claimed it could reach speeds of 120 miles per hour (190 km/h), the fastest documented speed was 90 miles per hour (140 km/h).Isamu Noguchi was involved with the development of the Dymaxion car, creating plaster wind tunnel models that were a factor in determining its shape, and during 1934 drove it for an extended road trip through Connecticut with Clare Boothe Luce and Dorothy Hale.The 1929 automobile of German inventor and helicopter pioneer Engelbert Zaschka exhibited features that were important to Buckminster Fuller. Zaschka's three wheeled car could also easily be folded, disassembled and re-assembled as could Fuller's Dymaxion House and many geodesic domes.The Dymaxion car was a three wheeler, steered by a single rear wheel, and could do a U-turn in its own length. However, the rear-wheel steering made the car somewhat counterintuitive to operate, especially in crosswind situations. The body was teardrop-shaped, and naturally aerodynamically efficient. The car was twice as long as a conventional automobile, at 20 feet (6.1 m) long. Drive power was provided by a rear-mounted Ford V8 engine, which produced 85 brake horsepower (63 kW; 86 PS) through the front wheels. The front axle was also a Ford component, being the rear axle of a contemporary Ford roadster turned upside-down.
I guess it was too ahead of it's time?
