No don't laugh. If BMW hadn't produced the 600; essentially an oversized bubble car in the 1950s, the company would probably never have survived. Sales of the miniature 600 bankrolled the company in austere times. And it fitted its era perfectly, with a 585cc version of BMW's contemporary flat-twin motorbike engine mounted in the tail. But with just 15kW, it struggled even to get to 100km/h.
