The BMW roundel — a black ring around blue and white quarters — is often said to depict a white propeller spinning against a blue sky, a nod to BMW’s origins in aircraft engines. It’s a great story, but BMW itself says it is a myth. The logo, registered in 1917, was derived from the round logo of its predecessor, Rapp Motorenwerke, with the letters BMW in the outer ring and the blue-and-white checks of the Bavarian state colors in the center. The propeller idea came from a 1929 BMW advertisement that showed the logo in a spinning propeller.

The real origin

When the company became Bayerische Motoren Werke in 1917, it kept the round shape and black outer ring of the Rapp logo, replacing the name with BMW and filling the center with blue and white quarters from the Bavarian flag. At the time, trademark rules restricted the use of state symbols in commercial logos, which is often cited as a reason the colors appear in a slightly different arrangement from the Bavarian flag’s pattern.

Where the propeller story came from

In 1929, BMW ran an advertisement for an aircraft engine it built under license, showing an airplane with the roundel superimposed on its spinning propeller. The image was so effective that the propeller interpretation stuck — and BMW itself repeated it for years. In recent years, BMW has publicly explained that the interpretation was popularized by advertising rather than being the logo’s original meaning.

The roundel today

BMW has updated the roundel several times, most recently with a flat, transparent-ring version used in communications from 2020, while cars keep a three-dimensional badge.

Logos with real stories

Other car logos have origins as interesting as BMW’s: the Mercedes-Benz star represents land, sea and air; Audi’s rings stand for four merged companies; the Rolls-Royce mascot has its own romantic tale. Read the Mercedes three-pointed star, Audi’s four rings and the Spirit of Ecstasy.
