2009-2011 Mercedes-Benz E-class T-modell (S212) E 220 CDI BlueEFFICIENCY (170 Hp)

Technical Specifications

The Mercedes-Benz E-Class T-modell (S212) E 220 CDI BlueEFFICIENCY, produced from 2009 to 2011, represented a compelling blend of practicality, efficiency, and luxury within the E-Class range. Positioned as a mid-range offering in the T-modell (estate) lineup, it catered to buyers seeking a spacious and economical vehicle without sacrificing the Mercedes-Benz brand experience. This variant utilized a refined diesel engine and a six-speed manual transmission, aiming for optimal fuel economy and reasonable performance. It was part of the S212 series, the third generation of E-Class estates, known for its improved interior quality and advanced technology compared to its predecessor.

Powertrain & Engine Architecture

The heart of the E 220 CDI BlueEFFICIENCY is the OM 651.924 2.1-liter inline-four cylinder diesel engine. This engine is a highly advanced design for its time, featuring common-rail direct injection and a variable geometry turbocharger. The ‘BlueEFFICIENCY’ designation indicates the inclusion of various fuel-saving technologies, including optimized engine management, reduced friction components, and an aerodynamic body. The engine produces 170 horsepower at 3000-4200 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1400-2800 rpm. This broad torque curve is characteristic of modern diesel engines and contributes to strong low-end responsiveness. The six-speed manual transmission was the standard offering, providing precise gear changes and allowing the driver to fully utilize the engine’s power band. The engine’s DOHC valvetrain with four valves per cylinder further enhances its efficiency and performance.

Driving Characteristics

The E 220 CDI BlueEFFICIENCY offered a comfortable and refined driving experience. While not a performance-oriented variant, the engine’s ample torque provided brisk acceleration, especially in the mid-range. The six-speed manual transmission allowed for precise control, but the gear ratios were tuned for economy rather than outright speed. Compared to the more powerful E 250 CDI or E 350 models, the E 220 CDI felt less urgent in its acceleration. However, it excelled in providing relaxed cruising and effortless overtaking on highways. The long gearing contributed to excellent fuel economy, making it an ideal choice for long-distance travel. The rear-wheel drive configuration provided balanced handling, although it wasn’t as engaging as some of its competitors with all-wheel drive systems.

Equipment & Trim Levels

The E 220 CDI BlueEFFICIENCY typically came equipped with a generous array of standard features. These included automatic climate control, a multi-function steering wheel, power windows and mirrors, and a high-quality audio system. Interior upholstery was typically a combination of fabric and Artico leather. Optional extras included a sunroof, navigation system, leather seats, and advanced driver-assistance systems like parking assist and lane keeping assist. Trim levels varied slightly depending on the market, but generally, the E 220 CDI offered a good balance of comfort and convenience features without the premium price tag of the higher-spec models.

Chassis & Braking

The S212 E-Class T-modell featured an independent multi-link suspension on both the front and rear axles, providing a comfortable and controlled ride. The suspension was tuned to prioritize comfort over sporty handling, but it still offered good body control and stability. The E 220 CDI typically came equipped with ventilated disc brakes on the front wheels and solid discs on the rear. Anti-lock braking system (ABS) was standard, along with electronic brakeforce distribution (EBD). The steering was a hydraulic power-assisted rack and pinion system, providing precise and responsive steering feel.

Market Reception & Comparison

The E 220 CDI BlueEFFICIENCY was well-received by critics for its fuel efficiency, comfortable ride, and spacious interior. It was often praised as a practical and sensible choice for families and business users. Compared to other trims in the E-Class lineup, the E 220 CDI offered the best fuel economy, making it an attractive option for those prioritizing running costs. However, some critics noted that its performance was not as exhilarating as the more powerful models. Against competitors like the BMW 3 Series Touring and Audi A4 Avant, the E-Class T-modell offered a more luxurious and refined interior, but the BMW often provided a more engaging driving experience.

Legacy

The OM 651 engine family, including the 2.1-liter variant used in the E 220 CDI, has proven to be remarkably durable and reliable. These engines are known for their longevity and relatively low maintenance costs. In the used car market, the E 220 CDI BlueEFFICIENCY remains a popular choice due to its fuel efficiency, practicality, and reputation for reliability. However, potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly on vehicles that have primarily been used for short journeys. Overall, the E 220 CDI BlueEFFICIENCY represents a well-engineered and practical estate car that continues to offer good value for money.
