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

The Mercedes-Benz W112 Cabriolet 300 SE represents the pinnacle of 1960s German luxury motoring. Produced between January 1964 and December 1967, this elegant convertible was part of the W112 series, a range of high-end saloons and coupes designed to bridge the gap between the standard Mercedes-Benz production models and the ultra-exclusive 600 series (W100). The 300 SE Cabriolet, powered by a sophisticated 3.0-liter inline-six engine, offered a unique blend of performance, comfort, and prestige, appealing to a discerning clientele seeking a refined open-air driving experience. It remains a highly sought-after classic, celebrated for its engineering and timeless design.

Mercedes-Benz W112 Cabriolet 300 SE: A Legacy of Luxury

The W112 series was conceived as a technologically advanced and luxurious offering from Mercedes-Benz. The “SE” designation stood for “Sonderausführung” (Special Edition), indicating a higher level of equipment and refinement compared to the standard models. The Cabriolet version, in particular, was a statement of opulence, featuring a fully automatic, hydraulically operated soft top and a meticulously crafted interior. While not produced in the same volumes as its saloon counterparts, the 300 SE Cabriolet cemented Mercedes-Benz’s reputation for building some of the finest automobiles in the world.

Engine & Performance

At the heart of the W112 Cabriolet 300 SE lies the M 189 VI inline-six engine, a 2,996 cc (182.83 cu. in.) masterpiece of engineering. This naturally aspirated 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 technology for the time, contributing to smooth power delivery and improved fuel efficiency. Power is sent to the rear wheels via a four-speed automatic transmission. Acceleration from 0 to 60 mph was achieved in approximately 10.8 seconds, and the car could reach a top speed of 195 km/h (121.17 mph). The weight-to-power ratio of 10.1 kg/Hp and a weight-to-torque ratio of 6.9 kg/Nm provided a respectable level of performance for a luxury car of its era. Fuel consumption was, by modern standards, considerable, ranging from 13.0 to 13.7 liters per 100 kilometers (18.1 – 17.2 US mpg).

Design & Features

The W112 Cabriolet 300 SE boasts a classic, elegant design characterized by its long hood, flowing lines, and understated chrome accents. The body style is a two-door cabriolet, offering seating for five passengers. The fully automatic soft top, a defining feature of the car, could be raised or lowered with ease, providing open-air enjoyment or protection from the elements. Inside, the cabin was lavishly appointed with high-quality materials, including leather upholstery, wood trim, and polished metal accents. Safety features, while limited by the standards of the 1960s, included disc brakes on all four wheels, a significant advancement for the time. The suspension system, featuring double wishbones at the front and a trailing arm setup at the rear, along with air suspension, provided a comfortable and controlled ride. The car’s dimensions – 4,880 mm (192.13 in.) in length, 1,845 mm (72.64 in.) in width, and 1,400 mm (55.12 in.) in height – reflected its status as a large, luxurious vehicle.
