1954-1955 Mercedes-Benz W187 Cabriolet A 220 (85 Hp)

The Mercedes-Benz W187, specifically the Cabriolet A 220 model, represents a pivotal moment in the post-war recovery of German automotive engineering. Produced between April 1954 and August 1955, this vehicle was not merely a car; it was a statement of renewed prosperity and a return to luxury for a nation rebuilding after the devastation of World War II. The W187 series, encompassing saloon, coupé, and cabriolet body styles, served as the intermediate model between the older 170 series and the later, more iconic “Fintail” models. While not widely exported to the United States, the W187 held significant importance in the European market, particularly as a symbol of aspirational ownership and sophisticated design.

Mercedes-Benz W187 Cabriolet A 220: A Post-War Icon

The W187 series was designed to bridge the gap between pre-war Mercedes-Benz traditions and the demands of a modernizing post-war world. It represented a deliberate move upmarket, offering a level of comfort and refinement previously unseen in the company’s entry-level offerings. The Cabriolet A 220, with its elegant open-top design, was the most desirable and exclusive variant, appealing to a clientele seeking both style and status. It’s important to note that the W187 was a relatively short-lived model, quickly superseded by more advanced designs, making surviving examples particularly sought after by collectors today.

Engine & Performance

The heart of the W187 Cabriolet A 220 is its 2.2-liter (2195 cm3) inline-six cylinder engine, designated the M180 I / 180.920. This naturally aspirated engine produced 85 horsepower at 4800 rpm and 157 Nm (115.8 lb.-ft.) of torque at 2400 rpm. While these figures may seem modest by modern standards, they were respectable for the early 1950s and provided the car with adequate performance for comfortable cruising. The engine featured a single overhead camshaft (SOHC) valvetrain and utilized a carburetor for fuel delivery. Power per liter was a respectable 38.7 Hp/l. Acceleration from 0 to 100 km/h (0-62 mph) took approximately 21 seconds, and it could achieve a top speed of 150 km/h (93.21 mph). The engine’s longitudinal front-engine layout and rear-wheel drive configuration were typical for European cars of the era. The weight-to-power ratio of 17.2 kg/Hp and weight-to-torque ratio of 9.3 kg/Nm indicate a balanced, if not particularly sporty, driving experience.

Design & Features

The W187 Cabriolet A 220 is characterized by its classic post-war styling, blending elegant lines with a sense of understated luxury. The two-door cabriolet body style allowed for open-air motoring, a popular choice among affluent buyers. The car could comfortably seat five passengers, although rear seating was relatively cramped by modern standards. The exterior design featured a prominent grille, rounded headlights, and flowing fenders. Inside, the cabin was appointed with high-quality materials, including leather upholstery and wood trim. Safety features were rudimentary by today’s standards, consisting primarily of robust construction and reliable drum brakes on all four wheels. The steering utilized a worm-reduction unit. The focus was on providing a comfortable and refined driving experience, rather than cutting-edge safety technology. The fuel tank capacity was 65 liters (17.17 US gal).
