INTRODUCTION
The S212 E-Class T-modell, launched in 2009, continued Mercedes-Benz’s long-standing tradition of producing high-quality, practical estate cars. The E 350 BlueEFFICIENCY variant, equipped with the M272 V6 engine and 7G-TRONIC transmission, occupied a sweet spot in the lineup, offering a significant step up in performance from the base models while remaining more accessible than the range-topping E 500 or the AMG versions. The “BlueEFFICIENCY” designation indicated the inclusion of various fuel-saving technologies, aiming to improve economy without sacrificing driving pleasure. This model was primarily aimed at European markets where estate cars (T-modells in Mercedes terminology) are highly popular, but also saw limited sales in North America.
Powertrain & Engine Architecture
At the heart of the E 350 BlueEFFICIENCY lies the M272.983 3.5-liter naturally aspirated V6 engine. This engine, a staple of the Mercedes-Benz lineup for several years, is known for its smooth operation and robust construction. It features a 60-degree V-angle, all-aluminum construction, and a sophisticated direct injection system. The direct injection system, combined with variable valve timing (DOHC), optimizes combustion efficiency and contributes to the engine’s respectable power output of 292 horsepower at 6400 rpm and 365 Nm (269.21 lb-ft) of torque available between 3000 and 5100 rpm. The 7G-TRONIC seven-speed automatic transmission is a key component of this powertrain. This transmission, renowned for its smooth and quick shifts, features a torque converter lock-up clutch that enhances efficiency at cruising speeds. The transmission’s gear ratios are tuned to provide a balance between acceleration and fuel economy, with a relatively tall final drive ratio to aid in highway efficiency.
Driving Characteristics
The E 350 BlueEFFICIENCY T-modell delivers a refined and comfortable driving experience. The 3.5-liter V6 provides ample power for everyday driving and effortless highway cruising. Acceleration from 0 to 60 mph takes approximately 6.7 seconds, making it a reasonably quick estate car. The 7G-TRONIC transmission contributes to the smooth power delivery, with minimal noticeable shift shock. Compared to the more powerful E 500, the E 350 feels less urgent in its acceleration, but it offers a more manageable and fuel-efficient driving experience. Against the four-cylinder models, the V6 provides a significant boost in performance and refinement. The rear-wheel drive configuration provides a balanced feel, although it can be less confident in slippery conditions compared to all-wheel drive variants.
Equipment & Trim Levels
The E 350 BlueEFFICIENCY T-modell came standard with a comprehensive list of features, reflecting its position as a mid-to-upper range model. Standard equipment typically 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 included features like a panoramic sunroof, navigation system, adaptive cruise control, and upgraded interior trim options. The interior design was characterized by Mercedes-Benz’s signature blend of luxury and functionality, with high-quality materials and a well-laid-out dashboard.
Chassis & Braking
The S212 E-Class T-modell features a sophisticated chassis design. The front suspension utilizes an independent multi-link setup, while the rear suspension employs an independent multi-link system with optional air suspension. The air suspension, available as an option, provides a particularly comfortable ride and allows for adjustable ride height. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The E 350 typically featured slightly smaller brake rotors compared to the higher-performance models, but still offered excellent braking performance for everyday driving. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The E 350 BlueEFFICIENCY T-modell was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and spacious interior. Critics noted that the fuel economy, while improved by the BlueEFFICIENCY technologies, was still relatively high compared to some of its competitors. Compared to the E 300 models, the E 350 offered a noticeable performance advantage. Against the E 500, it provided a more balanced combination of performance and economy. The BMW 5 Series Touring and Audi A6 Avant were its primary competitors, offering similar levels of luxury and practicality.
Legacy
The M272 engine, found in the E 350 BlueEFFICIENCY, is generally considered a reliable powerplant, although preventative maintenance is crucial. The 7G-TRONIC transmission is also known for its durability, but regular fluid changes are essential. Today, the S212 E-Class T-modell E 350 BlueEFFICIENCY represents a good value on the used car market. It offers a compelling combination of luxury, practicality, and performance at a relatively affordable price point. However, potential buyers should be aware of the potential for age-related issues, such as worn suspension components and electronic glitches. Overall, this variant remains a desirable choice for those seeking a refined and capable estate car.
