BMW 507

The BMW 507 was a brief but brilliant reinstatement of BMW’s sporting heritage that had flourished with the successful BMW 328 prior to World War II. Launched in 1955, the 507 was envisioned by American BMW importer Max Hoffman to fill the divide between the Mercedes-Benz 300SL and the far less expensive and powerful offerings from MG and Triumph. Mechanical components were largely sourced from the 502 and 503 series, with engineering led by Fritz Fiedler. Since Hoffman was dissatisfied with preliminary body designs, he eventually had Count Albrecht Goertz, who had the earlier 503 already to his credit, pen the sensuous lines of the 507.

As with all its cars, the 507 was a tangible expression of the characteristic BMW excellence in performance, construction and design. At once an elegant masterpiece and a downright gorgeous design with sensuous curves, the 507 was powered by the 3.2-liter overhead-valve aluminum block V-8 engine that was shared with the 502 and 503 series but developed a rated 150 bhp with twin carburetors.

Hoffman initially targeted a $5,000 price point for the 507, but BMW, which essentially hand-built each car, could not reach profitable production levels. The 507’s initial $9,000 price quickly escalated to over $11,000. Despite the increase, BMW reportedly lost money on each one. Production began in November 1956 following an unveiling at the 1955 Frankfurt Motor Show and ended two-and-a-half years later with only 251 examples built, not counting a completely different prototype and two “one-off” examples.

The design was slightly revised in 1957 with the appearance of the Series II models. Differences included increased engine output and a little additional space behind the seats to give taller drivers a more comfortable driving position. While many 507 Roadsters were purchased by their original owners purely on the basis of their stunning aesthetics and sporting open bodywork, the cars were sophisticated performers in the finest BMW tradition. A number of final-drive ratios were available with the 507, ranging from 3.70:1 to 4.20:1 depending upon the customer order, with top speeds for the 507 ranging from 124 to 136 mph. Acceleration from rest to 60 mph was equally impressive at 8.8 seconds, and while not intended for the drag strip, the 507 covered the quarter-mile in just 16.5 seconds.

This car was auctioned off by RM Auctions in January of 2012 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona.
