Ask anyone what the BMW roundel means and you’ll get the same answer. White propeller blades, blue sky, aviation heritage. It’s a charming story, and BMW made it up in an advertisement more than a decade after the badge was registered.
The badge dates to 1917, registered shortly after Bayerische Motoren Werke GmbH was founded as successor to Rapp Motorenwerke GmbH. Rapp had a black outer ring, and BMW kept it rather than starting from a blank page. Into the middle went blue and white quadrants, the colours of Munich and the state of Bavaria. Rapp Motorenwerke didn’t survive the name change, but its ring did.
Trademark rules of the day wouldn’t let BMW reproduce the Bavarian state flag exactly, so the quadrants ended up in the arrangement everyone recognises today. A legal restriction drew the badge. It’s been on the bonnet ever since, right through to the iX3 40 in BMW Australia showrooms.

BMW Roundel Came First, the Propeller Came Later
In 1929, with BMW then building aircraft engines, an advertisement put the roundel inside a spinning propeller. That’s the origin of the propeller story, a single advert. A 1942 company publication repeated the connection, which took it from marketing flourish to common knowledge, and there it stayed.
The logo pre-dates BMW’s first flight-tested aircraft engine, so a propeller couldn’t have been the inspiration for a badge that already existed. Historical records are blunt about it. The roundel was created to represent BMW and its Bavarian origins.
A Century of Quoting an Advert
The BMW roundel appeared on the R 32 in 1923, the company’s first motorcycle, 6 years before the propeller advert existed. Nobody looking at that tank badge had any reason to think of aircraft, because the story hadn’t been invented yet.
The badge outlived the aero engines and the advertisement that mythologised it. BMW Group now covers BMW, MINI, Rolls-Royce, and BMW Motorrad, with over 30 production sites and sales in more than 140 countries. In 2025 it sold 2.46 million passenger vehicles and more than 202,500 motorcycles, plus whatever the M Concept at Le Mans eventually becomes. All of them use the same 1917 device. Next time someone explains the propeller to you, they’re quoting a 1929 ad.
