Mercedes-Benz W128 Cabriolet 220 SE (120 Hp)

The Mercedes-Benz W128 Cabriolet 220 SE represents a pinnacle of post-war German automotive engineering and design. Produced between August 1959 and November 1960, this elegant convertible was part of the “Ponton” series, known for its unibody construction – a relatively new concept at the time. The 220 SE Cabriolet was positioned as a luxury vehicle, offering a sophisticated open-air driving experience. While not a high-volume seller compared to its sedan counterparts, the W128 Cabriolet remains a highly sought-after classic, embodying the refinement and build quality for which Mercedes-Benz became renowned.

The Mercedes-Benz W128 Cabriolet 220 SE

The W128 series, introduced in 1959, marked a significant evolution in Mercedes-Benz design. The “Ponton” name, meaning “pontoon” in German, referred to the car’s rounded, flowing lines and the integrated body-and-frame construction. This contrasted with the earlier models that featured separate chassis and bodywork. The 220 SE, the top-of-the-line variant, featured a larger engine and more luxurious appointments than the base 220. The Cabriolet version, with its fully retractable soft top, was the most exclusive and desirable model in the range.

Engine & Performance

The heart of the 220 SE Cabriolet is the M127 III inline-six cylinder engine, displacing 2.2 liters (2195 cm³ or 133.95 cu. in.). This engine produced 120 horsepower at 4800 rpm and 189 Nm (139.4 lb.-ft.) of torque at 3900 rpm. While these figures may seem modest by modern standards, they were respectable for the late 1950s, providing smooth and refined performance. The engine featured multi-port manifold fuel injection, a sophisticated technology for the era, contributing to improved fuel efficiency and drivability. Power per liter was a respectable 54.7 Hp/l. Acceleration from 0 to 100 km/h (0-62 mph) took approximately 15 seconds, and 0 to 60 mph was achieved in around 14.3 seconds. The car’s top speed was 165 km/h (102.53 mph). The engine’s longitudinal front-mount configuration and rear-wheel drive layout provided a balanced driving experience. The weight-to-power ratio was 11.8 kg/Hp, and the weight-to-torque ratio was 7.5 kg/Nm.

Design & Features

The W128 Cabriolet’s design was characterized by its elegant proportions and understated luxury. The two-door, five-seat configuration offered comfortable accommodation for passengers. The fully retractable soft top allowed for open-air motoring, enhancing the driving experience. The exterior styling featured prominent chrome accents, rounded headlights, and a distinctive grille. Inside, the cabin was appointed with high-quality materials, including leather upholstery and wood trim. While safety features were limited by the standards of the time, the W128 offered a robust construction and reliable braking system for its era. The car’s suspension, featuring a double wishbone setup at the front and a trailing arm arrangement at the rear, provided a comfortable ride. The steering utilized a cone worm with recirculation balls, offering precise control. The car’s dimensions included a length of 4700 mm (185.04 in.), a width of 1790 mm (70.47 in.), and a height of 1530 mm (60.24 in.). The wheelbase measured 2700 mm (106.3 in.).
