The U.S. version boasted 160 bhp, good for 193 cubic ins. and 0.60 mph. in 7.2 sec. Nearly 200 bhp could be obtained using later parts though high octane fuel was scarcely available in Europe so fewer were seen in this trim. This engine was coupled to a 4-speed hydraulically-operated clutch synchromesh gearbox allowing the 507 to storm hills with the greatest of ease in third or top at almost 100 mph. In the hands of a genuinely skilled driver it proved to be a thoroughbred design as an overall sports tourer. A near equal weight was distributed fore/aft and the tubular chassis gave the snug open-roadster 'high torsional rigidity' with an absence of scuttle shake on rippled roads. The adjustable koni telescopic dampers and 185 x 16 Continental Super Rekords benefitted handling. The rack-and-pinion steering system was precise albeit 'twitchy' by more modern standards. In terms of quiet running and refinement this compact BMW unit was superior to the engine which powered the contemporary Merceedes-Benz 300 SL though the 507 was never noted for exceptional performance especially with an output of 150 bhp as against 215 bhp for the 300 SL. A 507 with a modified camshaft as tested by long-time owner John Surtees turned 140 + mph on the Hockenheim track.
The BMW 507 is an extraordinary automotive art with a timeless striking sleek shape complete with or without a hard-top as well as having a smooth V8 and sound Germanic craftsmanship. The Germans are reputed to tend towards the English approach of 'Naturalism and Functionalism' in automotive art design. Perhaps the 507 reflects 'the beautiful functionality of an Aston-Martin DB3 Sports stream-lined racer.' Alas, the 507 was destined to commercial failure due to high cost at $9,000/26500 DM. Some of the few that owned one were famous owners, Greta Garbo, Prince Rainier of Monaco and Bond girl Ursella Andress. Only 253 were made and each is a rare collectors item…..
