Technical Specifications

INTRODUCTION

The C207 E-Class Coupe, launched in 2009, was Mercedes-Benz’s answer to the BMW 3 Series Coupe and Audi A5. It offered a more stylish and luxurious alternative to the E-Class sedan, with a focus on driving enjoyment. The E 220 CDI BlueEFFICIENCY, powered by the OM651 engine, was a significant variant, particularly in Europe where diesel engines held a substantial market share. It provided a balance between performance and fuel economy, making it a practical choice for long-distance travel. This model was available with both manual and automatic transmissions, with the automatic being a popular choice for its convenience.

Powertrain & Engine Architecture

At the heart of the E 220 CDI BlueEFFICIENCY lies the OM651.911, a 2.1-liter inline-four cylinder diesel engine. This engine is renowned for its robust construction and efficiency. It features common-rail direct injection, delivering fuel at extremely high pressure for optimized combustion. The engine is equipped with a variable geometry turbocharger (VGT) and an intercooler, enhancing both power and torque across a broad rev range. The “BlueEFFICIENCY” enhancements included optimized engine management, reduced friction components, and improved aerodynamics. The engine produced 170 horsepower at 3000-4200 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1400-2800 rpm. The standard transmission was a 6-speed manual, but a 5-speed automatic transmission (7G-TRONIC was not standard on this variant) was also offered, providing smooth and effortless gear changes.

Driving Characteristics

The E 220 CDI Coupe, with its 170 hp and automatic transmission, offered a comfortable and refined driving experience. While not overtly sporty, it provided ample power for everyday driving and confident overtaking capabilities. The automatic transmission, while not as quick-shifting as modern units, was well-matched to the engine’s torque curve, delivering smooth acceleration. The gear ratios were optimized for fuel efficiency, resulting in relaxed cruising at highway speeds. Compared to the more powerful E 350 Coupe, the E 220 CDI offered less outright performance, but its superior fuel economy and lower running costs made it an attractive alternative for drivers prioritizing practicality. The manual transmission version offered a more engaging driving experience, but the automatic was favored by many for its ease of use.

Equipment & Trim Levels

The E 220 CDI BlueEFFICIENCY came standard with a generous array of features, reflecting Mercedes-Benz’s commitment to luxury and comfort. Standard equipment included automatic climate control, a multi-function steering wheel, power-adjustable front seats, and a high-quality audio system. Safety features such as ABS, ESP, and multiple airbags were also standard. Optional extras included leather upholstery, a sunroof, a navigation system, and advanced driver-assistance systems like Distronic cruise control. Interior trim levels varied, with options for wood or aluminum accents. The overall interior design was elegant and understated, typical of Mercedes-Benz.

Chassis & Braking

The C207 E-Class Coupe featured a sophisticated chassis designed to provide a balance between comfort and handling. The front suspension utilized a multi-link independent setup with coil springs and a transverse stabilizer bar, while the rear suspension employed a similar multi-link design. This configuration ensured a smooth and controlled ride, even on uneven surfaces. The braking system consisted of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) was standard, providing enhanced stopping power and stability. The steering was a hydraulic power-assisted rack and pinion system, offering precise and responsive control.

Market Reception & Comparison

The E 220 CDI BlueEFFICIENCY was well-received by critics and consumers alike. It was praised for its fuel efficiency, comfortable ride, and refined interior. While some reviewers noted that the engine lacked the outright performance of its gasoline counterparts, the majority acknowledged that it provided ample power for most driving situations. Compared to the E 350 Coupe, the E 220 CDI offered significantly better fuel economy, making it a more economical choice for high-mileage drivers. Its reliability was generally considered good, although diesel engines can be more susceptible to issues with the fuel injection system and particulate filter over time.

Legacy

The OM651 engine, found in the E 220 CDI, has proven to be a durable and reliable powerplant. Well-maintained examples continue to provide years of service. On the used car market, the C207 E 220 CDI Coupe represents a relatively affordable entry point into Mercedes-Benz ownership. However, potential buyers should be aware of the potential for issues with the diesel particulate filter (DPF) and the fuel injection system, particularly on vehicles with high mileage. Overall, the E 220 CDI BlueEFFICIENCY remains a desirable and practical coupe, offering a compelling blend of luxury, efficiency, and reliability.
