The Mercedes-Benz E-Class Coupe (C207) E 250 CDI BlueEFFICIENCY, produced from July 2009 to April 2011, represented a compelling blend of performance and efficiency within the broader C207 E-Class Coupe range. Positioned as a mid-range offering, it catered to buyers seeking a refined coupe experience with the benefits of a modern diesel engine. This variant utilized the OM651 engine family, known for its robust construction and fuel economy, coupled with a six-speed manual transmission. It occupied a space between the more affordable E 220 CDI and the higher-performance E 350 CDI, appealing to those prioritizing a balance of power, economy, and comfort.

Technical Specifications

Powertrain & Engine Architecture

The heart of the E 250 CDI BlueEFFICIENCY is the OM651.911 2.1-liter inline-four diesel engine. This engine is a highly refined example of Mercedes-Benz’s diesel technology, featuring common-rail direct injection and a sophisticated bi-turbocharger system. The two-stage turbocharging, utilizing a small and a large turbocharger, minimizes turbo lag and provides a broad, flat torque curve. Peak torque of 500 Nm (368.78 lb.-ft.) is available from a low 1600-1800 rpm, providing strong acceleration in everyday driving situations. The engine also incorporates a particulate filter to reduce emissions, meeting Euro 5 standards. The six-speed manual transmission was standard, offering precise shifts and contributing to the car’s overall efficiency. While an automatic transmission was available as an option, the manual was favored by drivers seeking more control and a slightly more engaging driving experience.

Driving Characteristics

The E 250 CDI BlueEFFICIENCY offered a comfortable and refined driving experience. The high torque output of the diesel engine meant that strong acceleration was readily available, even with a full passenger load. The six-speed manual transmission allowed for precise gear selection, and the gear ratios were well-matched to the engine’s power delivery. Compared to the more powerful E 350 CDI, the E 250 CDI felt less urgent in its acceleration, but it still provided ample power for highway cruising and overtaking. The suspension, tuned for comfort, absorbed bumps and imperfections in the road well, providing a smooth and stable ride. The steering was precise and well-weighted, offering good feedback to the driver.

Equipment & Trim Levels

The E 250 CDI BlueEFFICIENCY came standard with a generous array of features, including automatic climate control, a multi-function steering wheel, and a high-quality audio system. Interior upholstery was typically Artico leather, a durable and comfortable synthetic leather. Optional extras included a sunroof, navigation system, heated seats, and a premium sound system. The dashboard layout was typical of Mercedes-Benz at the time, with a focus on elegance and functionality. The overall ambiance was one of understated luxury.

Chassis & Braking

The C207 E-Class Coupe featured a robust chassis with a multi-link independent suspension at all four corners. The front suspension utilized coil springs and a transverse stabilizer bar, while the rear suspension employed a similar setup. This configuration provided a good balance of comfort and handling. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) were standard, providing enhanced stopping power and stability. The E 250 CDI, being a mid-range model, typically featured slightly smaller brakes compared to the higher-performance variants.

Market Reception & Comparison

The E 250 CDI BlueEFFICIENCY was generally well-received by automotive critics. It was praised for its fuel efficiency, strong torque, and comfortable ride. However, some critics noted that the engine could be somewhat noisy compared to gasoline engines. Compared to the E 220 CDI, the E 250 CDI offered a noticeable performance upgrade, while still maintaining excellent fuel economy. Compared to the E 350 CDI, it offered a more affordable entry point into the E-Class Coupe range, albeit with less power. The combination of efficiency and practicality made it a popular choice for buyers seeking a stylish and economical coupe.

Legacy

The OM651 engine family, including the version used in the E 250 CDI BlueEFFICIENCY, 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 250 CDI BlueEFFICIENCY remains a desirable option for buyers seeking a well-built and fuel-efficient coupe. While older examples may require some maintenance, the engine’s inherent robustness ensures that it can provide many years of reliable service. The C207 E-Class Coupe, as a whole, is considered a stylish and well-engineered vehicle, and the E 250 CDI BlueEFFICIENCY represents a sweet spot in the range, offering a compelling blend of performance, efficiency, and luxury.
