As well as the Touring Coupé, several BMW 328 production models will be sent out onto the roads between Rome and Brescia, along with a range of BMW 328 Mille Miglia Roadsters and a BMW 328 Berlin-Rome Roadster. The youngest BMW to make the journey from Munich to Italy will be a BMW 507 built in 1957. In all, nine works cars will be lining up at the start of this year’s Mille Miglia, with seven further teams bearing the blue and white logo also expected in Brescia.
BMW 328 Berlin-Rome Touring Roadster
In the hope of competing in the Berlin-Rome race scheduled for 1941, Germany's National Sports Authority had three existing BMW Roadsters fitted with more advanced aerodynamic roadster bodies by Carrozzeria Touring of Milan. What ultimately emerged were racing cars that boasted an outstandingly good drag coefficient for the time. The events of the Second World War, however, put paid to any further motor racing events with German involvement.
Year of construction 1937 - chassis, 1941 body - Engine 6-cylinder in-line Displacement 1971 - cc Bore x Stroke 66 x 96 mm - Power output 136 bhp at 6000 rpm - Gearbox 4-speed - Brakes Alfin drums, vented brake back plates - Weight 780 kg - Max. speed 200 km/h (125 mph)
The 328 Roadster, developed in 1935/36, is one of the legends of automobile history. Although only modest facilities were available, the result was a sports car of most attractive appearance that soon dominated the two-litre class. Modified competition versions won their classes at Le Mans and in the Mille Miglia. Of the 464 cars that were built, 403 had the standard roadster body, the remaining chassis being used for racing versions or special bodywork ordered by customers.
Construction period 1936 - 1940 - Quantity 464 - Engine Six-cylinder in-line engine - Displacement 1971 cc Bore x Stroke 66 x 96 mm - Power output 80 bhp at 4500 rpm - Transmission Four-speed, central shift - Front brakes Hydraulic drum brakes - Rear brakes Hydraulic drum brakes Dimensions 3900 x 1550 x 1400 mm - Unladen weight 780 kg - Max. speed 155 km/h
BMW 328 Touring Coupé
The company Touring in Milan built a particularly light-weight "superleggera" coupé body on the BMW 328 chassis for use in fast long-distance races. The improved aerodynamics were intended to achieve much higher speeds. The car was first used in June 1939 in the 24-hour race at Le Mans. Max Prinz zu Schaumburg-Lippe and Hans Wencher won the 2-litre sports-car class in a new record time and came 5th in the overall placings. In April 1940, the car driven by Fritz Huschke von Hanstein and Walter Bäumer won a commanding overall victory in the Mille Miglia. Successes and the overall concept make this vehicle a unique racing legend.
Year of construction 1939 - Engine Six-cylinder in-line engine Displacement 1971 cc Bore x Stroke 66 x 96 mm - Power output 136 bhp at 6000 rpm - Gearbox Four-speed - Brakes Alfin drums, vented brake, back plates - Weight 780 kg - Max. speed 220 km/h (137 mph)
BMW 328 Mille Miglia Roadster
For lack of time, two of the three BMW 328 Roadster models scheduled to compete in the 1st Gran Premio Brescia delle Mille Miglia of 1940 had their bodywork built not in Munich, but by coachbuilders Touring of Milan on the basis of BMW designs. Like the BMW 328 Coupé, this aerodynamically advanced, ultra-lightweight body consisted of a tubular space frame with an aluminium skin. The team behind the wheel of this car comprised Willy Briem and Uli Richter, who propelled it to an outstanding fifth place overall in the 1940 Mille Miglia and thus played a key role in securing the team prize for BMW.
Year of construction 1940 - Engine 6-cylinder in-line Displacement 1971 cc Bore x Stroke 66 x 96 mm - Power output 130 bhp at 5750 rpm - Gearbox 4-speed - Brakes Alfin drums, vented brake, back plates - Weight 700 kg - Max. speed 200 km/h (125 mph)
The BMW 507 roadster was launched at the 1955 Frankfurt Motor Show. BMW had succeeded in creating one of the most beautiful sports cars of all time. The car was based on the technology of the 3.2 litre 502 saloon but with the power output increased to 150 bhp. The 507 was built to a design created by Albrecht Graf Goertz, a colleague of Raymond Loewy. This sports car, available with three different rear-axle transmission ratios and a range of top speeds between 190 and 220 km/h, worked wonders for the image of Bayerische Motoren Werke. Almost all BMW 507s, in many cases bought originally by international celebrities, are still on the road today. Two of them have special bodies.
Year of construction 1957 - Quantity 251 (1956 - 1959) - Engine Eight-cylinder V-engine - Displacement 3168 cc Bore x Stroke 82 x 75 mm - Power output 150 bhp at 5000 rpm - Transmission Four-speed, central shift - Front brakes Hydraulic duplex brakes with servo Rear brakes - Hydraulic simplex brakes with servo Dimensions 4380 x 1650 x 1260 mm - Unladen weight 1220 kg - Max. speed 205 km/h
