Powertrain & Engine Architecture
The E 250 D was powered by the OM 605 D 25, a 2.5-liter inline five-cylinder diesel engine. This engine utilized precombustion chamber injection, a system common in Mercedes-Benz diesels of the era, known for its relatively quiet operation and good combustion efficiency. The OM 605 featured a double overhead camshaft (DOHC) valvetrain, contributing to improved breathing and power delivery compared to older designs. The engine produced 113 horsepower at 5000 rpm and 170 Nm (125 lb-ft) of torque between 2800 and 4600 rpm. The automatic transmission was a five-speed unit, designed to provide smooth shifts and enhance the car’s cruising comfort. This transmission was not known for its sportiness, prioritizing refinement and ease of use over rapid gear changes.
Driving Characteristics
The E 250 D Automatic offered a comfortable and relaxed driving experience. Acceleration was modest, with a 0-60 mph time of around 14.6 seconds, making it unsuitable for drivers seeking spirited performance. However, the engine’s torque characteristics provided adequate power for everyday driving and overtaking maneuvers. The automatic transmission, while smooth, could feel somewhat sluggish, particularly when downshifting. Compared to the manual transmission versions of the E 250 D, the automatic offered less driver engagement but greater convenience. Higher-output E-Class models, such as the E 320, provided significantly more power and a more dynamic driving experience, but at the cost of increased fuel consumption.
Equipment & Trim Levels
The E 250 D Automatic typically came equipped with features such as power windows, central locking, and an AM/FM radio. Higher trim levels offered options like leather upholstery, sunroof, automatic climate control, and upgraded audio systems. The interior design was typical of Mercedes-Benz at the time, emphasizing quality materials and a functional layout. Wood trim was often included, adding a touch of luxury to the cabin. Safety features included ABS anti-lock brakes and airbags, representing a significant advancement in automotive safety for the mid-1990s.
Chassis & Braking
The W210 E-Class featured a double wishbone front suspension and an independent multi-link rear suspension, providing a comfortable ride and good handling characteristics. The E 250 D typically used ventilated disc brakes at the front and solid discs at the rear. The suspension was tuned for comfort, prioritizing ride quality over sporty handling. A stabilizer bar was included at both the front and rear to reduce body roll during cornering. The hydraulic power steering provided light and precise steering feel.
Market Reception & Comparison
The E 250 D Automatic was well-received in European markets, where diesel engines were popular due to their fuel efficiency and low running costs. Critics praised the car’s comfort, build quality, and safety features. However, some reviewers noted the engine’s lack of outright power and the automatic transmission’s somewhat sluggish performance. Compared to other E-Class variants, the E 250 D offered the best fuel economy, making it an attractive option for high-mileage drivers. The E 320 provided more performance, while the E 220 CDI (introduced later in the W210’s lifecycle) offered a more modern diesel engine with improved efficiency and power.
Legacy
The OM 605 engine family, including the 2.5-liter version found in the E 250 D, is known for its durability and reliability. With proper maintenance, these engines can accumulate very high mileage. The W210 E-Class, while prone to some age-related issues such as rust and electrical problems, remains a popular choice among classic Mercedes-Benz enthusiasts. The E 250 D Automatic, in particular, is valued for its fuel efficiency and comfortable ride. In the used car market, these vehicles are generally affordable and offer a good value for those seeking a well-built and reliable sedan.
