Powertrain & Engine Architecture
The heart of the E 250 D is the OM 605 D 25 engine, a 2.5-liter inline five-cylinder diesel. This engine is characterized by its robust construction and precombustion chamber injection system. Unlike direct injection diesels, the OM 605 utilizes pre-chambers to initiate combustion, resulting in quieter operation and reduced engine knock. The engine’s DOHC (Double Overhead Camshaft) valvetrain contributes to efficient gas exchange, while the relatively low compression ratio of 22:1 aids in durability. The 5-speed manual transmission was standard, providing a balance between fuel efficiency and drivability. The gearbox was known for its smooth shifts and durability, contributing to the overall reliability of the vehicle.
Driving Characteristics
The E 250 D, with its 113 horsepower and 173 lb-ft of torque, wasn’t designed for rapid acceleration. Zero to 60 mph took around 14.8 seconds, and top speed was limited to 118 mph. However, the engine’s torque delivery was strong from low RPMs, making it well-suited for everyday driving and highway cruising. The manual transmission allowed for precise control, but the gear ratios were optimized for fuel economy rather than performance. Compared to the E 300 D, the E 250 D offered less power but better fuel economy. Against the gasoline-powered E 280, the diesel provided significantly better fuel efficiency but lacked the responsiveness and refinement of the petrol engine.
Equipment & Trim Levels
The E 250 D typically came with a respectable level of standard equipment for its time. This included power windows, central locking, and a basic audio system. Interior upholstery was typically cloth, although leather was available as an option. Dashboard configuration was consistent with other W124 models, featuring a functional and ergonomic layout. Optional extras included a sunroof, automatic climate control, and upgraded audio systems. The trim level was generally considered mid-range, offering a good balance of comfort and features without the luxury appointments of the higher-end models.
Chassis & Braking
The W124 chassis provided a solid and stable platform for the E 250 D. Front suspension utilized a wishbone design, while the rear featured an independent multi-link setup, offering a comfortable ride and good handling characteristics. Braking was accomplished via disc brakes on all four wheels, supplemented by an ABS (Anti-lock Braking System) for enhanced safety. The E 250 D’s weight of approximately 3130 lbs was relatively moderate for its size, contributing to manageable handling. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The E 250 D was generally well-received by critics as a practical and reliable diesel sedan. Its fuel economy was a major selling point, particularly in Europe where diesel fuel was significantly cheaper than gasoline. However, its performance was often criticized as being underwhelming. Compared to the E 300 D, the E 250 D offered a more affordable entry point into the W124 range, but at the cost of some power. Its reliability was consistently praised, making it a popular choice for those seeking a long-lasting and dependable vehicle.
Legacy
The OM 605 engine, found in the E 250 D, is renowned for its durability and longevity. Many examples have surpassed 300,000 miles with proper maintenance. Today, the W124 E 250 D remains a sought-after classic car, particularly among enthusiasts who appreciate its robust engineering and simple mechanics. Parts availability is generally good, and the relatively straightforward design makes it a relatively easy vehicle to maintain. While not a performance icon, the E 250 D represents a high point in Mercedes-Benz diesel technology and continues to offer a comfortable and reliable driving experience.
