Bayerische Motoren Werke, or more popularly known the world over as BMW, is one of the oldest car manufacturers in the entire world. Founded in the year 1916, BMW did not start as a car manufacturing company. As a matter of fact, they were geared towards creating aircraft engines for military planes. They were one the leading aircraft engine producers during World War I. It was only after the war that they ceased creating aircraft engines and instead ventured into motorcycle and automobile creation. BMW pays homage to their roots in the design of their car logos. The logo is a representation of propellers with the blue sky in the back.
BMW are thought to be one of the best automakers in the world, but before they turned their attention to making cars in 1918 they actually made airplanes and engines, which is what the white propeller in their logo represents.
