The Mercedes-Benz W124, produced from 1985 to 1996, represented a significant leap forward in engineering and design for the German automaker. The facelifted version introduced in 1989 brought subtle but important refinements to the already highly regarded platform. Among the various models within the W124 range, the 300 D 4MATIC, equipped with a 3.0-liter diesel engine producing 113 horsepower, offered a compelling blend of fuel efficiency, durability, and all-weather capability. This model, while not widely sold in the United States during its production run, became a popular choice in European markets seeking a robust and reliable luxury sedan.
Mercedes-Benz W124 300 D 4MATIC: A Detailed Overview
The W124 series was intended as a replacement for the W201 (190E) and W123 models, offering a more modern and sophisticated package. The 300 D 4MATIC, specifically, catered to buyers who desired the refinement of a Mercedes-Benz sedan with the added security and traction of all-wheel drive. The 4MATIC system, a key feature, distinguished it from rear-wheel-drive counterparts and positioned it as a practical option for regions experiencing inclement weather. The 1989 facelift brought improvements to the exterior styling, interior appointments, and mechanical components, enhancing the overall driving experience.
Engine & Performance
The heart of the 300 D 4MATIC is its OM 603 D 30 inline-six cylinder diesel engine, displacing 2,996 cubic centimeters (182.83 cubic inches). This engine, a hallmark of Mercedes-Benz diesel technology, delivers 113 horsepower at 4,600 rpm and 191 Nm (140.87 lb.-ft.) of torque at 2,700 rpm. While not a performance-oriented vehicle, the 300 D 4MATIC provides adequate power for comfortable cruising and everyday driving. The engine’s robust construction and precombustion chamber injection system contribute to its renowned longevity and reliability. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 15 seconds, while reaching 0 to 60 mph is achieved in around 14.3 seconds. The top speed is rated at 183 km/h (113.71 mph). Fuel economy is a strong point, with combined consumption figures of 7.4 l/100 km (31.8 US mpg or 38.2 UK mpg).
Design & Features
The W124 300 D 4MATIC is a four-door sedan with a classic, understated design. The 1989 facelift brought subtle changes to the front and rear fascias, including a revised grille and taillight design. The interior is characterized by its high-quality materials, comfortable seating for five occupants, and a focus on practicality. Safety features, while not as comprehensive as those found in modern vehicles, included an Anti-lock Braking System (ABS), which was a significant advancement for the time. The 4MATIC system itself is a key feature, providing enhanced traction and stability on slippery surfaces. The vehicle’s dimensions are substantial, measuring 4,740 mm (186.61 inches) in length, 1,740 mm (68.5 inches) in width, and 1,450 mm (57.09 inches) in height. Trunk space is a generous 520 liters (18.36 cubic feet).
