Anyone know where the BMW symbol started from? Here's some history on it.
The famous white and blue symbol of BMW stems from the company's origins as aeroplane engine manufacturers.
Many aircraft were painted in regional colours and those of the Bavarian Luftwaffe were the Bayern white and blue.
It is said that the pilot's view through the propeller was one of white and blue
alternating segments.
Through the years this image has become stylised into solid quarters of blue and white to declare the identity of today's BMW cars and motorcycles. Since the end of the 1970s BMW has worked to create a standardised international image in terms of statement and presentation so that today whenever people encounter the company's symbols they recognise BMW
