BMW has reiterated that its iconic roundel emblem does not represent a spinning propeller, a misconception that has persisted despite previous clarifications. The widely held belief stems from a 1929 print advertisement depicting the logo superimposed on aircraft propellers, a visual narrative further reinforced by a 1942 company publication.
The actual design of the BMW roundel, officially registered in October 1917, combines elements from its predecessor, Rapp Motorenwerke. The black outer ring of the emblem is derived from Rapp's corporate badge. The inner quadrants, featuring blue and white, represent the colors of the Bavarian state.
Due to local trademark regulations, BMW was unable to replicate the Bavarian flag's color arrangement precisely. To comply with these laws and avoid potential legal issues, the company inverted the order of the blue and white segments within the four quadrants of the roundel.
The emblem first appeared on a production vehicle in 1923, adorning the BMW R 32 motorcycle. Its automotive debut followed in 1929 on the BMW 3/15 PS DA 2. While the core design has remained consistent, the logo has undergone several refinements over the decades, including changes in typography, color shades, and dimensionality, culminating in the transparent flat design introduced in 2020.
