For decades, the spin on BMW's signature roundel — the automaker's logo, which looks like a propeller blade set against a blue sky — was that it represented a propeller blade set against a blue sky. The design was supposedly a tribute to the roots of Bayerische Motoren Werke (or Bavarian Motor Works in English) in the early 20th century, when the company built aircraft engines.
Well, think again.
In last Sunday's Automobiles section, I wrote about visiting a quartet of German car museums. At the BMW Museum in Munich, my affable tour guide, Anne Schmidt-Possiwal, explained that the blue-and-white company logo did not represent a spinning propeller, but was meant to show the colors of the Free State of Bavaria.
