It’s not the most unique vehicle in the world, but the Isetta micro-car built in several countries and once owned by BMW, still attracts plenty of attention because of its bubble shape and diminutive size.
Design by an Italian company, the Isetta was conceived because of a need for cheap, short-distance city driving following World War II.
The BMW Isetta became the world’s first mass-production 3-liter car in 1955. Its low-friction, one-cylinder engine and low weight resulted in superior gas mileage — as high as 71 mpg. It is the top-selling one cylinder car in the world, with 161,728 units sold, according to Wikipedia.
Matt Walsh, a friend and publisher of the irreverent cycling blog Twisted Spoke spotted a stunning 1956 BMW Isetta in the San Francisco Bay Area and forwarded a few images he took with his iPhone.
