1952 BMW 501

The BMW 501 was a luxury car manufactured by BMW from 1952 to 1958. Introduced at the first Frankfurt Motor Show in 1951, the 501 was the first BMW model to be manufactured and sold after the Second World War, and as the first BMW car built in Bavaria. The 501 and its derivatives, including the V8 powered BMW 502, were nicknamed “Baroque Angels” by the German public. The BMW 502 was the first postwar German car to be manufactured with a V8 engine.

While the 501 and 502 model numbers were discontinued in 1958, variations of the model, with the same platform and body, were continued until 1963.

Autovelo restarts “BMW” production

Meanwhile, BMW AG restarted manufacture on a much smaller scale, starting with pots and pans, and eventually moving up to household hardware and bicycles. Eventually, with permission from the U.S. authorities and funding from the banks under which BMW had been put into receivership, they began manufacturing motorcycles in 1948.^[3]

To end Autovelo’s continued trademark infringement, the Eisenach branch of BMW was dissolved effective 28 September 1949 and was legally severed as at 11 October. Without any legal arguments to continue using BMW’s name and logo, Autovelo changed the name to EMW (Eisenacher Motoren Werke) and changed the blue colour in the logo to red.

Three approaches to car manufacture

Donath

Kurt Donath, technical director of BMW and general manager of the Milbertshofen factory,^[3] was soliciting manufacturers, including Ford and Simca, to produce their vehicles under licence. In particular, Donath was looking to produce old products under licence, so that he could buy tooling along with the licence.^[4]

Böning

Grewenig

The BMW 331 was proposed for production to the management, where it was vetoed by sales director Hanns Grewenig. Grewenig, a banker and former Opel plant manager, believed that BMW’s small production capacity was best suited to luxury cars with high profit margins, similar to the cars BMW made just before the war. To this end, he had Böning and his team create the car that would become the 501.

Design and engineering

The 501 was an all-new platform, with a perimeter frame, double A-arm front suspension with torsion bar springs, and a live axle with torsion bar springs at the rear. The steering mechanism was similar to a rack and pinion system except that the rack was semi-circular instead of straight.

The 501 was powered by the M337 engine, a development of the BMW M78 used in the pre-war BMW 326.

The four-speed gearbox was not bolted to the engine, but was a separate shaft-driven unit mounted between the second and third crossmembers. While the remote gearbox placement led to a complicated linkage to the column-mounted shifter, resulting in vague shifter action, it also improved legroom for the front passengers.

The body was designed in house by Peter Schimanowski. After seeing the prototype, BMW’s management commissioned Pininfarina to build an alternative. The Pininfarina prototype was thought to be too similar to his design for the Alfa Romeo 1900 saloon, so BMW stayed with Schimanowski’s design.^[5] The steel body was far heavier than Schimanowski had calculated it to be, resulting in the completed car having a dry weight of 1,430 kilograms (3,150 lb).^[6] Performance suffered as a result, with a top speed of 135 km/h (84 mph) and acceleration to 100 km/h (62 mph) taking 27 seconds, both of which compared unfavourably with the six-cylinder Mercedes-Benz 220.

One innovation was the attention paid to passive safety. The car featured a robust chassis providing above average side impact protection, an unusually short steering column with the steering gear set well back from the front of the car, and a fuel tank placed in a carefully protected location above the rear axle in order to minimize fire risk in the event of an accident.

Reception and production

Development issues delayed the start of production until late 1952, and even then BMW still did not have equipment for pressing body panels in operation.The first 2,045 four-door saloon bodies were built by Karosserie Baur and were shipped from Baur in Stuttgart to BMW’s factory in Munich for assembly. The thousandth 501 was completed on 1 September 1953.

The 501 and derivatives built at BMW were four-door saloons. Coupe and convertible versions were available as custom orders from Baur or Autenrieth.

A road test of the 501 in March 1953 by Auto- und Motorrad-Welt reported better than average wind resistance, as well as good ride quality and an effective heating system. The fuel consumption was reported to be 10.3 L/100 km (27 mpg_‑imp; 23 mpg_‑US).

Development of the BMW 501

The engine and the model designation were altered again in the spring of 1955. The 501A and 501 B were replaced by the 501/3, with an updated M337 engine. The 501/3 was introduced alongside the 501 V8, which featured a detuned version of the 2.6-litre V8 introduced in the 502 the previous year. The 501/3 and 501 V8 were continued until 1958, when the six-cylinder engine and the 501 model designation were discontinued.
