The Mercedes-Benz W112 Coupe 300 SE, produced between January 1964 and December 1967, represents a pinnacle of 1960s German automotive engineering and luxury. This elegant coupe, part of the larger W112 series, was designed to offer a sophisticated alternative to the standard sedan, appealing to buyers seeking a blend of performance, comfort, and exclusivity.

It occupied a premium segment, competing with grand tourers from brands like BMW and Jaguar.

The Mercedes-Benz W112 Coupe 300 SE: A Legacy of Engineering

The W112 series, introduced in 1961, was Mercedes-Benz’s response to the growing demand for more luxurious and technologically advanced automobiles. The Coupe variant, the 300 SE, further elevated this concept. It was positioned above the standard 300 SE sedan in terms of price and exclusivity. The “SE” designation stood for “Sonderausführung” (Special Edition), indicating a higher level of equipment and refinement. The W112 series as a whole was significant for introducing several innovations, including disc brakes on all four wheels and a sophisticated air suspension system, features that were relatively uncommon at the time.

Engine & Performance

The heart of the 300 SE Coupe is its 2,996 cc (182.83 cu. in.) inline-six cylinder engine, designated M 189 VI / 189.987. This engine produced 170 horsepower at 5,400 rpm and 249 Nm (183.65 lb.-ft.) of torque at 4,000 rpm. The engine featured multi-port manifold fuel injection, a relatively advanced system for the era, contributing to its smooth power delivery and respectable performance. While not overtly sporty, the 300 SE Coupe offered brisk acceleration, achieving 0-60 mph in approximately 11.4 seconds and a top speed of 200 km/h (124.27 mph). The engine’s power-to-weight ratio was 9.7 kg/Hp, and its torque-to-weight ratio was 6.6 kg/Nm. Power per liter was a respectable 56.7 Hp/l for a naturally aspirated engine of this displacement. The engine is longitudinally mounted and drives the rear wheels through a 4-speed manual transmission.

Design & Features

The 300 SE Coupe’s design is characterized by its elegant lines, long hood, and graceful roofline. The two-door coupe body style, seating five passengers, offered a more sporting and intimate experience than the four-door sedan. The car’s exterior styling was understated yet sophisticated, reflecting the prevailing German design aesthetic of the 1960s. Inside, the 300 SE Coupe was lavishly appointed with high-quality materials, including wood trim, leather upholstery, and chrome accents. The air suspension system provided a remarkably smooth and comfortable ride, absorbing road imperfections with ease. Disc brakes on all four wheels ensured confident stopping power. The car’s dimensions – 4880 mm (192.13 in.) in length, 1845 mm (72.64 in.) in width, and 1395 mm (54.92 in.) in height – positioned it as a substantial grand tourer. The wheelbase measured 2750 mm (108.27 in.).
