Powertrain & Engine Architecture
The E 400d 4MATIC is powered by the OM 656 D 29 SCR, a 2.9-liter inline-six cylinder diesel engine. This engine is a significant departure from the older V6 diesels used in previous E-Class generations, representing a move towards modular engine designs within the Mercedes-Benz portfolio. The OM 656 features a steel piston design, a stepped combustion process, and a two-stage turbocharging system. This configuration allows for high torque output at low engine speeds (700 Nm available from 1200 rpm) while maintaining good fuel efficiency. The engine utilizes a diesel commonrail fuel injection system, delivering precise fuel metering for optimized combustion. The 9G-TRONIC nine-speed automatic transmission is standard, providing smooth and efficient gear changes. This transmission is known for its wide gear ratio spread, contributing to both fuel economy and responsive acceleration.
Driving Characteristics
The E 400d 4MATIC delivers a refined and effortless driving experience. The high torque output of the engine provides strong acceleration in virtually any gear, making overtaking maneuvers easy and confident. The 9G-TRONIC transmission is well-tuned, offering seamless shifts and contributing to a relaxed cruising experience. Compared to the E 220d or E 300d models, the E 400d offers a substantial performance upgrade, with noticeably quicker acceleration and a more authoritative feel. While not a sports car, the E 400d handles well for its size and weight, thanks to the 4MATIC all-wheel-drive system which provides excellent traction in all conditions. The suspension is tuned for comfort, absorbing bumps and imperfections in the road effectively.
Equipment & Trim Levels
The E 400d 4MATIC T-modell typically came well-equipped as standard. Common features included leather upholstery, heated front seats, a premium sound system, a large infotainment display with navigation, and a comprehensive suite of safety features such as adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras included air suspension, a panoramic sunroof, upgraded interior trim materials, and advanced driver assistance systems. Trim levels varied by market, but generally offered increasing levels of luxury and technology.
Chassis & Braking
The S213 E-Class estate features a multi-link independent suspension at all four corners, providing a comfortable ride and good handling characteristics. The 4MATIC all-wheel-drive system utilizes a multi-plate clutch to distribute torque between the front and rear axles, optimizing traction in various conditions. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability program (ESP) and anti-lock braking system (ABS) are standard features, enhancing safety and control.
Market Reception & Comparison
The E 400d 4MATIC T-modell was generally well-received by automotive critics. It was praised for its powerful and efficient engine, comfortable ride, spacious interior, and practical estate body style. Compared to its competitors, such as the Audi A6 Avant and BMW 5 Series Touring, the E 400d offered a compelling combination of luxury, performance, and fuel economy. While the initial purchase price was higher than the lower-powered E-Class variants, the E 400d represented a good value for buyers seeking a premium and capable all-around vehicle.
Legacy
The OM 656 engine has proven to be a robust and reliable powerplant. While long-term reliability data is still accumulating, early reports suggest that the engine is generally durable and capable of high mileage with proper maintenance. The E 400d 4MATIC T-modell remains a desirable used car, particularly for those seeking a comfortable and practical luxury estate with strong performance. The combination of a powerful diesel engine, all-wheel drive, and a spacious interior makes it a versatile vehicle for both daily commuting and long-distance travel.
