[pedant] Up till Christmas 1939 the JU52 transport was the only BMW powered aeroplane in widespread use. Their best war time engine was the 801, which powered the FW190A, but that engine did not enter production until 1940. [/pedant]
Though I take your point about their bike being awful.
The Audi actually looks like a sensible commuter, discs, belt drive, hub gears, rack and dynamo lights. The sort of bike I'd expect from a German manufacturer, I'd be surprised if it's not supplied by one of them.
But it will probably be bought at vast expense because it says 'Audi' on it. And that paint....
