Mercedes-Benz W112 Coupe 300 SE (170 Hp) Automatic

The Mercedes-Benz W112 Coupe 300 SE represents a pinnacle of 1960s German engineering and luxury. Produced between January 1964 and December 1967, this elegant coupe was part of the larger W112 series, designed as a more luxurious and technologically advanced alternative to the W111 “Fintail” models. While the W112 series included saloons and convertibles, the Coupe, with its flowing lines and sophisticated features, held a special place in the Mercedes-Benz lineup. It catered to a discerning clientele seeking a blend of performance, comfort, and prestige. The 300 SE Coupe, powered by a 3.0-liter inline-six engine, offered a refined driving experience and cemented Mercedes-Benz’s reputation for building high-quality automobiles.

The Mercedes-Benz W112 Coupe: A Legacy of Luxury

The W112 series was conceived as a step upmarket from the already well-regarded W111. It incorporated advancements in engine technology, suspension design, and overall refinement. The Coupe variant, in particular, distinguished itself with its graceful silhouette and exclusive appeal. It wasn’t a mass-market vehicle; production numbers were relatively low, adding to its desirability among collectors today. The 300 SE designation indicated the engine displacement and fuel injection system – a significant feature for the time. The W112 Coupe was primarily sold in Europe, but a limited number found their way to North America, appealing to buyers who appreciated European craftsmanship and engineering.

Engine & Performance

At the heart of the 300 SE Coupe lay the M 189 VI 3.0-liter inline-six cylinder engine. This engine, producing 170 horsepower at 5400 rpm and 249 Nm (183.65 lb-ft) of torque at 4000 rpm, was a marvel of engineering for its era. It featured multi-port manifold fuel injection, a relatively advanced system that improved efficiency and performance compared to carbureted engines. The engine’s longitudinal front-engine layout contributed to balanced handling. Power was delivered to the rear wheels via a four-speed automatic transmission. While not a sports car, the 300 SE Coupe offered respectable performance for a luxury vehicle of its time, achieving a 0-60 mph time of approximately 10.5 seconds and a top speed of 195 km/h (121.17 mph). The power-to-weight ratio of 9.7 kg/Hp and torque-to-weight ratio of 6.6 kg/Nm provided a smooth and effortless driving experience.

Design & Features

The W112 Coupe’s design was characterized by its elegant proportions and understated luxury. The two-door coupe body style, accommodating five passengers, featured a long hood, a flowing roofline, and a relatively short rear deck. The exterior styling was refined and sophisticated, reflecting the design sensibilities of the 1960s. Inside, the cabin was appointed with high-quality materials, including leather upholstery, wood trim, and polished metal accents. The 300 SE Coupe prioritized passenger comfort and offered features such as power windows, power steering, and a sophisticated heating and ventilation system. A notable technological advancement was the air suspension system, which provided a remarkably smooth and comfortable ride. Safety features, while not as comprehensive as those found in modern vehicles, included disc brakes on all four wheels, a significant improvement over drum brakes. The vehicle’s dimensions – 4880 mm (192.13 in) in length, 1845 mm (72.64 in) in width, and 1395 mm (54.92 in) in height – provided ample space for passengers and luggage.
