1985-1989 Mercedes-Benz W124 300 D (109 Hp) 4MATIC Automatic

The Mercedes-Benz W124 300 D 4MATIC Automatic, produced between December 1985 and August 1989, represents a significant evolution in the mid-size luxury sedan segment. Part of the W124 series, which succeeded the W201, this model distinguished itself through its robust engineering, refined comfort, and, crucially, the addition of Mercedes-Benz’s 4MATIC all-wheel-drive system. While not initially a high-volume seller in the United States (the W124 series was sold in the US from 1986-1993, but the 300 D 4MATIC was less common), the 300 D 4MATIC offered a compelling combination of diesel efficiency and all-weather capability, particularly appealing in regions with challenging climates. The W124 series, as a whole, established a new benchmark for build quality and safety, solidifying Mercedes-Benz’s reputation for engineering excellence.

The Mercedes-Benz W124 300 D 4MATIC: A Detailed Overview

The W124 series was designed with a focus on longevity and passenger safety. It represented a departure from the more angular styling of the preceding W201, adopting a more rounded and aerodynamic form. The 300 D 4MATIC, specifically, catered to buyers seeking a durable and economical vehicle capable of handling diverse road conditions. The integration of the 4MATIC system, a permanent all-wheel-drive setup, provided enhanced traction and stability, making it a practical choice for those living in areas prone to snow or inclement weather. This model was primarily sold in Europe, where diesel engines and all-wheel drive were more popular than in the North American market at the time.

Engine & Performance

The heart of the W124 300 D 4MATIC is its 3.0-liter inline-six cylinder diesel engine, designated OM 603 D 30 / 603.913. This engine produces 109 horsepower at 5000 rpm and 210 Nm (154.89 lb.-ft.) of torque at 2200 rpm. While the horsepower figure might seem modest by modern standards, the engine’s strength lies in its substantial torque output, providing ample pulling power for comfortable cruising and effortless acceleration. The engine utilizes precombustion chamber injection, a technology common in Mercedes-Benz diesels of the era, contributing to its efficiency and durability. Power is delivered to all four wheels via a four-speed automatic transmission. Performance figures include a 0-100 km/h (0-62 mph) acceleration time of 16 seconds and a maximum speed of 178 km/h (110.6 mph). The weight-to-power ratio is 14.3 kg/Hp, and the weight-to-torque ratio is 7.4 kg/Nm.

Design & Features

The W124 300 D 4MATIC is a four-door sedan with a seating capacity of five passengers. Its body style is characterized by clean lines, a relatively upright stance, and a spacious interior. The 4MATIC system adds a slight increase in weight compared to rear-wheel-drive W124 models, but the benefits in terms of handling and traction outweigh this drawback. Safety features, for the time, were a significant selling point. The W124 incorporated features like ABS (Anti-lock Braking System) and a robust crumple zone design, contributing to improved occupant protection in the event of a collision. The interior is well-appointed, with comfortable seating and a focus on practicality. Trunk space is a generous 520 liters (18.36 cu. ft.). The vehicle’s dimensions are: length 4740 mm (186.61 in), width 1740 mm (68.5 in), and height 1431 mm (56.34 in). The wheelbase measures 2800 mm (110.24 in).

Technical Specifications

The Mercedes-Benz W124 300 D 4MATIC Automatic remains a highly regarded vehicle among enthusiasts, celebrated for its durability, comfort, and all-weather capability. It represents a high point in Mercedes-Benz engineering, offering a blend of luxury and practicality that continues to appeal to drivers today.
