The Mercedes-Benz W111 Coupe 280 SE represents the pinnacle of elegant grand touring from the German automaker during the late 1960s and early 1970s. Produced between November 1967 and May 1971, this two-door coupe was part of the larger W111 family, which also included saloons (sedans). The 280 SE Coupe, distinguished by its sophisticated styling and robust engineering, catered to a discerning clientele seeking a blend of luxury, performance, and exclusivity. It occupied a premium segment, competing with other high-end coupes from manufacturers like BMW and Jaguar. This model is highly regarded by collectors today for its build quality and classic design.
The Mercedes-Benz W111 Coupe 280 SE: A Detailed Overview
The W111 series, introduced in 1959, was a significant step forward for Mercedes-Benz, representing a modern aesthetic and advanced engineering for the era. The Coupe variant, with its flowing lines and reduced roofline, offered a more sporting and stylish alternative to the four-door saloon. The “SE” designation indicated “Einspritzmotor” – fuel injection – a relatively advanced feature for the time, signifying a higher level of performance and refinement. The 280 SE specifically utilized a 2.8-liter inline-six engine with multi-port fuel injection, delivering a smooth and responsive driving experience.
Engine & Performance
The heart of the 280 SE Coupe is its 2778 cc (169.52 cu. in.) inline-six cylinder engine, designated the M 130 E 28 / 130.980. This engine produced 160 horsepower at 5500 rpm and 240 Nm (177.01 lb.-ft.) of torque at 4250 rpm. The engine’s power-to-liter ratio was a respectable 57.6 hp/l for the period. Power is delivered to the rear wheels via a four-speed automatic transmission. While not a sports car in the modern sense, the 280 SE Coupe offered respectable performance for its time, achieving a 0-60 mph (0-96 km/h) time of approximately 10.6 seconds and a top speed of 111.85 mph (180 km/h). The weight-to-power ratio of 9.4 kg/Hp and a weight-to-torque ratio of 6.3 kg/Nm contributed to a balanced driving experience. Fuel consumption was, by modern standards, considerable, averaging 12.3 l/100 km (19.1 US mpg or 23 UK mpg).
Design & Features
The W111 Coupe’s design is characterized by its elegant proportions and understated luxury. The two-door coupe body style, with its long hood and short deck, exudes a classic grand touring aesthetic. The interior was lavishly appointed with high-quality materials, including wood trim, leather upholstery, and chrome accents. The 280 SE Coupe offered seating for five passengers, although rear seat space was somewhat limited.
Safety features, while not as comprehensive as those found in modern vehicles, were relatively advanced for the late 1960s. Disc brakes were fitted to all four wheels, providing improved stopping power compared to drum brakes. The car’s robust construction and crumple zones offered a degree of crash protection. The focus, however, was primarily on providing a comfortable and refined driving experience, with features like power steering and a sophisticated heating and ventilation system enhancing passenger comfort. The car’s overall design prioritized aesthetics and a sense of occasion, making it a desirable vehicle for those seeking a statement of personal style and affluence.
