Technical Specifications

INTRODUCTION

The S213 E-Class T-modell, launched in 2016, represented a significant step forward in Mercedes-Benz’s estate car offerings. The E 400d 4MATIC, introduced in 2018, was a key variant, leveraging the advanced OM 656 diesel engine to deliver substantial performance and efficiency. Built on the MRA (Modular Rear-wheel-drive Architecture) platform, shared with other Mercedes-Benz models, the S213 offered a refined driving experience and a spacious, luxurious interior. The E 400d specifically targeted buyers who needed the practicality of a wagon but weren’t willing to compromise on power or refinement.

Powertrain & Engine Architecture

The heart of the E 400d is the OM 656 2.9-liter inline-six cylinder diesel engine. This engine marked a departure from the previous V6 diesel configurations, offering improved smoothness and efficiency. The OM 656 utilizes a stepped combustion process and a two-stage turbocharging system, enhancing both power and torque delivery. The engine employs a common-rail direct injection system operating at extremely high pressures (2700 bar) for optimized fuel atomization. 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. The 4MATIC all-wheel-drive system distributes power between the front and rear axles, enhancing traction and stability in various driving conditions.

Driving Characteristics

The E 400d 4MATIC T-modell delivers a remarkably refined driving experience. The 700 Nm (516 lb-ft) of torque, available from a low 1200 rpm, provides effortless acceleration in virtually any gear. The 9G-TRONIC transmission is well-tuned, offering seamless shifts and contributing to a relaxed cruising experience. While not as overtly sporty as the AMG variants, the E 400d offers ample power for overtaking and maintaining high speeds on the autobahn. Compared to the E 220d or E 300d models, the E 400d provides a noticeable performance advantage, with a 0-60 mph time of around 4.8 seconds. The all-wheel-drive system inspires confidence in inclement weather, providing enhanced grip and stability. The suspension, typically featuring Mercedes’ AIRMATIC air suspension (often optional), delivers a comfortable ride, absorbing bumps and imperfections in the road surface effectively.

Equipment & Trim Levels

The E 400d 4MATIC T-modell typically came well-equipped as standard. Features included leather upholstery, heated front seats, a premium sound system, and a comprehensive suite of safety technologies such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. The MBUX infotainment system, with its voice control functionality and large touchscreen display, was also standard. Optional extras included a panoramic sunroof, upgraded leather packages, rear seat entertainment, and various driver assistance systems. Trim levels varied by market, but generally offered options for enhanced interior finishes and exterior styling cues.

Chassis & Braking

The S213 E-Class T-modell utilizes an independent multi-link suspension system at both the front and rear axles, providing a comfortable and controlled ride. The E 400d typically featured larger brakes compared to the lower-powered variants, with ventilated discs at all four corners. The electronic stability program (ESP) and anti-lock braking system (ABS) are standard, enhancing safety and control. Steering is rack-and-pinion with electric power assistance, offering precise and responsive handling. The 4MATIC all-wheel-drive system contributes to improved stability and traction, particularly in challenging road conditions.

Market Reception & Comparison

The E 400d 4MATIC T-modell was generally well-received by automotive critics. It was praised for its powerful engine, refined driving experience, and spacious interior. Compared to its siblings, the E 400d offered a significant performance upgrade over the E 220d and E 300d models, while remaining more practical and affordable than the high-performance AMG variants. Fuel economy was also a strong point, with the E 400d achieving respectable figures for a vehicle of its size and performance. However, some critics noted the higher price tag compared to other estate cars in the segment.

Legacy

The OM 656 engine, as featured in the E 400d, has proven to be a robust and reliable powerplant. While modern diesel engines are subject to increasing scrutiny regarding emissions, the OM 656 incorporates advanced technologies to minimize pollutants. On the used car market, the E 400d 4MATIC T-modell holds its value well, appealing to buyers seeking a luxurious and capable estate car. Maintenance costs are generally comparable to other premium diesel vehicles, but preventative maintenance, particularly regarding the diesel particulate filter (DPF), is crucial for long-term reliability. The S213 E-Class T-modell, and the E 400d variant in particular, represents a high point in Mercedes-Benz’s estate car lineage, combining performance, luxury, and practicality in a compelling package.
