INTRODUCTION
The S212 E-Class T-modell, launched in 2009, represented a significant step forward in the luxury wagon segment. The E 350 CDI BlueEFFICIENCY 4MATIC, introduced in 2010, combined a potent diesel engine with Mercedes-Benz’s renowned all-wheel-drive system and a sophisticated seven-speed automatic transmission. This configuration aimed to deliver a refined driving experience, excellent fuel economy, and the practicality expected of a station wagon. Within the S212 range, the E 350 CDI 4MATIC occupied a sweet spot, offering a substantial power upgrade over the base diesel models (like the E 250 CDI) without reaching the higher price point and performance of the E 63 AMG.
Powertrain & Engine Architecture
At the heart of the E 350 CDI 4MATIC lies the OM 642.858 3.0-liter V6 diesel engine. This engine is a robust and well-regarded unit, known for its durability and strong torque output. It features a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine also incorporates a variable geometry turbocharger and intercooler, enhancing both power and efficiency. The 24-valve DOHC (Double Overhead Camshaft) valvetrain ensures precise control of the engine’s breathing. The 7G-TRONIC PLUS automatic transmission, a seven-speed unit, is characterized by smooth and quick shifts. It features a torque converter lock-up clutch that engages in most driving situations, improving fuel efficiency. The transmission also offers manual shift capability via steering wheel-mounted paddles or the gear selector.
Driving Characteristics
The E 350 CDI 4MATIC delivers a refined and effortless driving experience. The 620 Nm (457 lb-ft) of torque, available from a low 1600 rpm, provides strong acceleration in virtually any gear. The 7.3-second 0-60 mph time is respectable for a wagon of this size and weight. The 7G-TRONIC PLUS transmission is well-matched to the engine, providing seamless gear changes and contributing to a relaxed cruising experience. Compared to the manual transmission versions, the automatic offers greater convenience, particularly in urban traffic. While not as overtly sporty as the E 63 AMG, the E 350 CDI 4MATIC offers ample power for overtaking and highway driving. The 4MATIC all-wheel-drive system provides excellent traction in all weather conditions, enhancing stability and confidence.
Equipment & Trim Levels
The E 350 CDI BlueEFFICIENCY 4MATIC typically came well-equipped as standard. Features included leather upholstery, automatic climate control, a premium audio system, and a host of safety features such as ABS, ESP, and multiple airbags. Optional extras were plentiful, including a panoramic sunroof, navigation system, adaptive cruise control, parking assist, and upgraded interior trim options. The “BlueEFFICIENCY” designation indicated the inclusion of fuel-saving technologies such as start-stop functionality and optimized aerodynamics. Interior trim levels varied, with options ranging from wood veneers to aluminum accents.
Chassis & Braking
The S212 E-Class T-modell utilized a sophisticated independent suspension system. The front suspension featured a multi-link setup with coil springs and a stabilizer bar, while the rear suspension employed a multi-link design with air suspension available as an option. The air suspension provided adjustable ride height and damping, enhancing both comfort and handling. Braking duties were handled by ventilated disc brakes on all four wheels. The anti-lock braking system (ABS) and electronic stability program (ESP) were standard, providing enhanced safety and control. Steering was via a hydraulic power steering system, offering precise and responsive handling.
Market Reception & Comparison
The E 350 CDI BlueEFFICIENCY 4MATIC was generally well-received by automotive critics. It was praised for its powerful and efficient engine, comfortable ride, and spacious interior. Compared to the E 250 CDI, the E 350 CDI offered a significant performance boost, making it a more appealing option for drivers who frequently travel long distances or carry heavy loads. Compared to the petrol-powered E 350, the CDI version offered superior fuel economy. However, some critics noted that the diesel engine could be slightly noisy compared to its petrol counterpart. Reliability was generally good, although diesel particulate filter (DPF) issues could occur with infrequent long-distance driving.
Legacy
The OM 642 engine family, including the OM 642.858 found in the E 350 CDI, has proven to be remarkably durable. Well-maintained examples continue to provide reliable service today. The 7G-TRONIC PLUS transmission is also known for its longevity. In the used car market, the S212 E-Class T-modell E 350 CDI 4MATIC remains a popular choice for buyers seeking a practical, comfortable, and efficient luxury wagon. Its combination of performance, space, and all-wheel-drive capability continues to make it a compelling option, even as newer models have emerged. However, potential buyers should be aware of the potential for DPF issues and ensure that the vehicle has been properly maintained.
