The rivalry between the two Bavarian automobile brands, BMW and Audi, is long-standing. It takes place in many segments across the premium market, even transcending the four wheeled realm. BMW’s motorcycle production predates its first car, and not only one but three of the five brands that would later become Audi were also manufacturers of motorcycles.
Currently, the two firms continue to battle on the motorcycle front, though not directly as Audi AG doesn’t sell Audi branded motorcycles. BMW, of course, has their Motorrad division, whereas Audi competes with a subsidiary of another one of its wholly owned subsidiaries, Ducati.
