The car will become efficient



Buckminster Fuller : Indusrial designer
"The Dymaxion car was designed by Buckminster Fuller in the early 1930s. The car featured highly innovative, and ultimately influential, features compared with the common car of the day including: a three wheel design with rear wheel steering and front wheel drive, a longer body (20 feet), and a highly aerodynamic design. Success of the design was realized in its performance efficiencies: the car could transport up to 11 passengers, reach speeds of up to 90 miles per hour, and ran 30 miles per gallon."
"Although the Dymaxion cars were not produced, the design was influential on several subsequent designs. Buckminster Fuller's Dymaxion concept of obtaining optimal efficiency by Aurel Persu's aerodynamic design and employing the most advantageous materials, although obvious, may have especially influenced such designs as the Aptera hybrid car prototype[citation needed], which, like the Dymaxion, is a three-wheeled, ultra light, aerodynamic, fuel-efficient vehicle design."
