Mercedes-Benz W111 Cabriolet 280 SE (160 Hp)

The Mercedes-Benz W111 Cabriolet 280 SE represents the pinnacle of open-top luxury from the German automaker during the late 1960s. Produced between November 1967 and May 1971, this model is the final iteration of the W111 series, succeeding the 250 SE and 230 SE Cabriolets. The “SE” designation stands for “Sonderausstattung” (Special Equipment), indicating a higher level of standard features and refinement. The W111 Cabriolet was never officially sold in large numbers in the United States, but found a dedicated following among those seeking sophisticated European motoring. It occupies a significant place in automotive history as a symbol of post-war German engineering and design.

The Mercedes-Benz W111 Cabriolet 280 SE

The W111 series, introduced in 1959, was a comprehensive redesign for Mercedes-Benz, replacing the earlier “Fintail” models. The Cabriolet and Coupe versions, while sharing the W111 chassis and mechanical components, were styled differently, offering a more elegant and sporting appearance. The 280 SE Cabriolet, with its larger engine and improved features, is considered the most desirable version of the W111 open-top, representing the culmination of years of development and refinement. It was positioned as a luxury vehicle, competing with offerings from Jaguar and other premium European brands.

Engine & Performance

The heart of the 280 SE Cabriolet is the M 130 E 28 inline-six cylinder engine, displacing 2.8 liters (2778 cm³ or 169.52 cu. in.). This engine produced 160 horsepower at 5500 rpm and 240 Nm (177.01 lb.-ft.) of torque at 4250 rpm. Featuring multi-port manifold fuel injection, the engine delivered smooth and responsive performance. Power is delivered to the rear wheels through a four-speed manual transmission. While not a sports car, the 280 SE offered respectable acceleration, achieving 0-60 mph in approximately 10 seconds and a top speed of 190 km/h (118.06 mph). The engine’s power-to-weight ratio of 9.9 kg/Hp and torque-to-weight ratio of 6.6 kg/Nm contributed to a refined driving experience. Fuel economy, however, was relatively low for the period, averaging 12.3 l/100 km (19.1 US mpg or 23 UK mpg).

Design & Features

The W111 Cabriolet boasts a classic and elegant design. Its two-door, five-seat configuration provides comfortable accommodation for passengers. The fully automatic soft top, a defining feature of the Cabriolet, could be raised or lowered with ease, offering open-air motoring when desired. The body lines are characterized by their flowing curves and understated elegance, reflecting the design sensibilities of the late 1960s. Inside, the cabin is appointed with high-quality materials, including wood trim and leather upholstery. Safety features, while limited by the standards of the time, included disc brakes on all four wheels, a significant advancement for the era. The spacious trunk offered 530 liters (18.72 cu. ft.) of storage. The car’s dimensions – 4880 mm (192.13 in.) in length, 1845 mm (72.64 in.) in width, and 1435 mm (56.5 in.) in height – provided a substantial presence on the road.
