A special sport suspension, and a close-ratio 5-speed manual gearbox, were included along with a limited-slip diff and larger wheels'

BMW 507



The BMW 507 is a roadster produced by BMW from 1956 to 1959. Initially intended to be exported to the United States at a rate of thousands per year, it ended up being too expensive, resulting in a total production figure of 252 cars and heavy losses for BMW.

The BMW 507 was conceived by US automobile importer Max Hoffman who, in 1954, persuaded the BMW management to produce a roadster version of the BMW 501 and BMW 502 saloons to fill the gap between the expensive Mercedes-Benz 300SL and the cheap and underpowered Triumph and MG sports cars. Existing designs by Ernst Loof were rejected by Hoffman, who found them to be unappealing. In November 1954, at Hoffman's insistence, BMW contracted designer Albrecht von Goertz to design the BMW 503 and the 507.BMW engineer Fritz Fiedler was assigned to design the mechanical package, using existing components wherever possible.



The 507 shared the frame of the 503, shortened from 2,835 millimetres (111.6 in) to 2,480 millimetres (98 in).Overall length was 4,835 millimetres (190.4 in), and overall height was 1,257 millimetres (49.5 in). Curb weight was about 1,330 kilograms (2,900 lb).[14] The body was almost entirely hand-formed of aluminium, and no two models were exactly the same. Many cars were sold with an optional hand-fabricated removable hardtop. Because of the car-to-car differences, each hardtop fits only the car for which it was made.


Front suspension was parallel double wishbones, with torsion bar springs and an anti-roll bar. Rear suspension had a live axle, also sprung by torsion bars, and located by a Panhard rod and a central, transverse A-arm to control acceleration and braking forces. Brakes were Alfin drum brakes of 284.5 mm (11.2 in) diameter, and power brakes were optional. Late-model 507s had front Girling disc brakes.

The engine was the aluminium alloy BMW OHV V8, of 3,168 cubic centimetres (193.3 cu in) displacement, with pushrod-operated overhead valves. It had two Solex Zenith 32NDIX two-barrel carburetors, a chain-driven oil pump, and a compression ratio of 7.8:1, yielding 150 horsepower (110 kW) DIN at 5,000 rpm. It was mated to a close ratio four-speed manual transmission.[3] The standard rear-end ratio was 3.70:1, but ratios of 3.42:1 and 3.90:1 were optional.A contemporary road test of a 507 with the standard 3.70:1 final drive was reported in Motor Revue, stating a 0–100 km/h (0-62 mph) acceleration time of 11.1 seconds and a top speed of 122 mph.
