The Mercedes-Benz E 320 CDI T-modell, part of the S211 facelift series produced from 2006 to 2009, represented a compelling blend of luxury, practicality, and diesel efficiency within the E-Class range. Positioned as a mid-to-upper trim level, it offered a significant step up in performance and refinement compared to the base E 280 CDI, while remaining more accessible than the high-performance E 500 or the AMG variants. This station wagon (estate) body style, popular in Europe, provided a spacious and versatile alternative to the sedan, catering to buyers needing ample cargo capacity without sacrificing the Mercedes-Benz driving experience. The “facelift” designation refers to styling and technological updates applied to the S211 generation, enhancing its appeal and competitiveness.

Powertrain & Engine Architecture
The heart of the E 320 CDI T-modell was the OM 642.921, a 3.0-liter V6 turbodiesel engine. This engine was a significant advancement in Mercedes-Benz diesel technology, featuring common-rail direct injection and a variable geometry turbocharger. The common-rail system, operating at extremely high pressures, allowed for precise fuel metering and optimized combustion, resulting in improved power, efficiency, and reduced emissions. The V6 configuration provided inherent smoothness and refinement compared to inline engines. The engine produced 224 horsepower at 3800 rpm and a substantial 540 Nm (398 lb-ft) of torque between 1600 and 2400 rpm. This torque output, available across a broad rev range, was a key characteristic of the engine, providing effortless acceleration and strong pulling power. The 5G-TRONIC automatic transmission, a five-speed unit, was specifically calibrated to work with the engine’s torque curve, offering smooth and responsive shifts.
Driving Characteristics
The E 320 CDI T-modell offered a refined and comfortable driving experience. The abundant torque meant that the car felt strong and responsive in everyday driving situations, with minimal need to downshift. While not a sports car, the 0-60 mph time of around 7.7 seconds was respectable for a large station wagon. The 5G-TRONIC transmission contributed to a relaxed cruising experience, while the 4MATIC all-wheel-drive system provided enhanced traction and stability, particularly in adverse weather conditions. Compared to the E 280 CDI, the E 320 CDI offered noticeably more power and a more effortless feel. The higher-output E 500 provided significantly more horsepower, but at the expense of fuel economy. The manual transmission options available on other E-Class models were not offered with the E 320 CDI, reflecting its focus on comfort and ease of use.
Equipment & Trim Levels
The E 320 CDI T-modell typically came well-equipped as standard. Features included automatic climate control, power-adjustable front seats, a multi-function steering wheel, and a premium audio system. Leather upholstery was standard, along with wood trim accents. Optional extras included a sunroof, navigation system, upgraded audio, parking sensors, and adaptive cruise control. The T-modell also benefited from the estate-specific features such as a self-leveling rear suspension and a power-operated tailgate. Trim levels were relatively simple, with options primarily focused on adding individual features rather than distinct packages.
Chassis & Braking
The S211 E-Class featured a sophisticated chassis design. The front suspension utilized a double wishbone setup, while the rear employed an independent multi-link system with a stabilizer bar. This configuration provided a good balance between ride comfort and handling precision. The E 320 CDI T-modell was equipped with disc brakes on all four wheels, along with ABS (Anti-lock Braking System) and Electronic Stability Program (ESP) for enhanced safety. The 4MATIC all-wheel-drive system distributed power between the front and rear axles as needed, optimizing traction and stability.
Market Reception & Comparison
The E 320 CDI T-modell was generally well-received by automotive critics. It was praised for its powerful and efficient engine, comfortable ride, and spacious interior. The combination of diesel economy and V6 performance was particularly appealing. Fuel economy figures of around 28 mpg combined were considered excellent for a vehicle of its size and capability. Compared to competitors like the BMW 5 Series Touring and Audi A6 Avant, the E 320 CDI offered a compelling blend of luxury, practicality, and refinement. Reliability was generally good, although some owners reported issues with the diesel particulate filter (DPF) and the electronic systems.
Legacy
The OM 642 engine family, including the OM 642.921 found in the E 320 CDI, proved to be remarkably durable and reliable. Well-maintained examples continue to provide dependable service today. The 5G-TRONIC transmission, while not the most modern unit, is generally robust. In the used car market, the E 320 CDI T-modell remains a sought-after vehicle for those seeking a spacious, comfortable, and fuel-efficient station wagon with a touch of Mercedes-Benz luxury. However, potential buyers should be aware of the potential for DPF issues and the cost of maintaining the complex electronic systems.
