BMW 328 Mille Miglia Roadster was a racing car, that was designed to be raced at the 1st Gran Premio Brescia delle Mille Miglia in 1940. As with the BMW 328 Coupe, this aerodynamically highly advanced and extremely lightweight body consisted of a spaceframe with aluminium outer skin. The car weighted 700kg and with the 2.0-litre, six-cylinder engine producing 136 horsepower, the BMW 328 Mille Miglia Roadster could reach a top speed of 200 km/h.
Munich-based racing driver Uli Richter was handed the task of taking the finished car out in the icy cold for a series of high-speed runs along the autobahns outside Munich. However, the streamlined roadster required only minimal improvements. Another two space frames had already been mounted to the requisite chassis, but the clock was starting to tick. The body department in Munich was understaffed for the job in hand and there were fears that the two racers would not be ready to meet the spring deadline. Due to the time pressure, two of the three BMW 328 Roadsters weren’t produced in Munich but in Milan, by the coachbuilder Touring. The driver team of Willy Briem and Uli Richter piloted the car to an outstanding fifth place overall in the 1940 Mille Miglia and played a central role in securing the team prize for BMW in the process.
