The Mercedes-Benz W124 300 D Turbo 4MATIC

The W124 series, launched in 1985, was intended as a successor to the W201 (190E) and W123 models. It represented a significant step forward in terms of safety, comfort, and technology. The 300 D Turbo 4MATIC specifically addressed the demand for a high-performance diesel sedan with all-weather capability. The 4MATIC system, Mercedes-Benz’s brand name for its all-wheel-drive technology, provided enhanced traction and stability, particularly valuable in challenging road conditions common in European climates. This model was primarily marketed in Europe, where diesel engines enjoyed widespread acceptance due to favorable taxation and fuel costs.

Engine & Performance

The heart of the W124 300 D Turbo 4MATIC is its 3.0-liter inline-six cylinder diesel engine, designated OM 603 D 30 A / 603.963. This engine produces 147 horsepower at 4600 rpm and 273 Nm (201.35 lb-ft) of torque at 2400 rpm. The turbocharger significantly boosts power output compared to naturally aspirated diesel engines of the time, providing improved acceleration and cruising ability. The engine utilizes precombustion chamber injection, a technology common in Mercedes-Benz diesels, for efficient combustion and reduced emissions. 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 11.8 seconds and a maximum speed of 198 km/h (123.03 mph). The weight-to-power ratio of 10.7 kg/Hp and weight-to-torque ratio of 5.8 kg/Nm demonstrate a reasonable balance between power and weight for a vehicle of its class and era.

Design & Features

The W124 300 D Turbo 4MATIC is a four-door sedan with a classic, understated Mercedes-Benz design. Its body is characterized by clean lines, a robust build, and a focus on aerodynamic efficiency. The interior is designed for comfort and practicality, offering seating for five passengers. Key features include a well-appointed cabin with high-quality materials, comfortable seating, and a functional dashboard layout. Safety features, considered advanced for the late 1980s, include an Anti-lock Braking System (ABS) to prevent wheel lockup during braking, enhancing stability and control. The 4MATIC all-wheel-drive system itself is a primary feature, providing superior traction in slippery conditions. The vehicle’s dimensions – 4740 mm (186.61 in) in length, 1740 mm (68.5 in) in width, and 1431 mm (56.34 in) in height – provide a spacious interior and a substantial presence on the road. Trunk space is a generous 520 liters (18.36 cu. ft.).
