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 utilizes precombustion chamber injection, a system common in Mercedes-Benz diesels of the era. This system involves injecting fuel into a small precombustion chamber connected to the main cylinder, promoting more complete combustion and reducing engine noise. The engine produces 113 horsepower at 5000 rpm and 173 Nm (127.6 lb-ft) of torque between 2000 and 4600 rpm. The engine features a double overhead camshaft (DOHC) valvetrain, contributing to improved breathing and efficiency. Paired with the engine is a four-speed automatic transmission, designed for smooth operation and ease of use. This transmission was a standard feature, with a manual transmission not offered on this specific variant in most markets.
Driving Characteristics
The E 250 D Automatic delivers a driving experience focused on comfort and fuel economy rather than outright speed. Acceleration from 0 to 60 mph takes approximately 15.2 seconds, and the top speed is around 116 mph. The automatic transmission, while providing convenience, does slightly diminish performance compared to a manual transmission. The gear ratios are tuned for relaxed cruising, prioritizing fuel efficiency at highway speeds. The engine’s torque characteristics provide adequate power for everyday driving and overtaking maneuvers, but it lacks the responsiveness of higher-output engines like the E 300 D. The ride quality, typical of the W124, is smooth and composed, absorbing road imperfections effectively.
Equipment & Trim Levels
The E 250 D Automatic typically came equipped with a respectable level of standard features. These included power windows, central locking, and a basic audio system. Interior upholstery was generally cloth, although leather options were available as upgrades. The dashboard layout is functional and straightforward, reflecting the W124’s emphasis on practicality. Optional extras included a sunroof, upgraded audio systems, and climate control. The trim level was generally considered mid-range, offering a balance between affordability and luxury.
Chassis & Braking
The W124 E-Class features a robust chassis with independent suspension all around. The front suspension utilizes a wishbone design, while the rear employs a multi-link setup. This configuration provides a comfortable ride and good handling characteristics. The E 250 D is equipped with disc brakes on all four wheels, providing adequate stopping power. An Anti-lock Braking System (ABS) was standard, enhancing safety and stability during braking. Steering is handled by a cone worm and recirculation balls system with hydraulic power assistance, offering a balanced feel.
Market Reception & Comparison
The E 250 D Automatic was generally well-received by critics and buyers alike. It was praised for its fuel efficiency, comfortable ride, and build quality. Compared to the E 220 D, the E 250 D offered a noticeable performance improvement. However, the E 300 D, with its larger engine and higher output, provided a more dynamic driving experience. The E 250 D’s automatic transmission was seen as a convenience feature, but some enthusiasts preferred the greater control offered by a manual gearbox. Fuel economy was a key selling point, making it an attractive option for drivers covering long distances.
Legacy
The OM 605 engine family, including the 605.911 found in the E 250 D, is renowned for its durability and longevity. These engines are known to withstand high mileage with proper maintenance. Today, the E 250 D Automatic remains a relatively affordable entry point into W124 ownership. While finding well-maintained examples can be challenging, the robust engineering of the car ensures that many are still on the road. The E 250 D represents a sweet spot in the W124 range, offering a blend of practicality, comfort, and reliability that continues to appeal to enthusiasts and classic car buyers.
