Powertrain & Engine Architecture
The E 220 CDI BlueEFFICIENCY utilized the OM651.924 2.1-liter inline-four cylinder diesel engine. This engine was a cornerstone of Mercedes-Benz’s diesel offerings, known for its robust construction and efficiency. It featured common-rail direct injection, delivering fuel at extremely high pressure for optimized combustion. The engine was equipped with a variable geometry turbocharger and an intercooler, enhancing both power and torque across a broad rev range. The ‘BlueEFFICIENCY’ designation indicated the inclusion of various fuel-saving technologies, including start-stop functionality and optimized engine management. The 7G-TRONIC PLUS automatic transmission, a seven-speed unit, was paired with the engine. This transmission offered smooth and quick shifts, contributing to both performance and fuel economy. It featured a torque converter lock-up clutch that engaged in most driving situations, minimizing energy loss.
Driving Characteristics
The 170 hp and 400 Nm (295 lb-ft) of torque provided by the E 220 CDI BlueEFFICIENCY offered a comfortable and capable driving experience. Acceleration from 0 to 60 mph took approximately 8.2 seconds, and top speed was limited to 134 mph. While not a sports-oriented variant, the engine delivered ample power for everyday driving and overtaking maneuvers. The 7G-TRONIC PLUS transmission was well-tuned, providing seamless gear changes and contributing to a relaxed cruising experience. Compared to the more powerful E 350 models, the E 220 CDI offered less outright performance, but its lower weight and efficient engine resulted in significantly better fuel economy. The automatic transmission, while convenient, didn’t offer the same level of driver engagement as the available six-speed manual gearbox.
Equipment & Trim Levels
The E 220 CDI BlueEFFICIENCY typically came standard with features such as automatic climate control, a multi-function steering wheel, power windows and mirrors, and a basic audio system. Upholstery was generally cloth, with leather options available as an upgrade. Common optional extras included a sunroof, navigation system, premium sound system, parking sensors, and heated seats. The S212 E-Class offered a wide range of customization options, allowing buyers to tailor the vehicle to their preferences. Trim levels varied by market, but generally, the E 220 CDI BlueEFFICIENCY was positioned as a well-equipped mid-range option.
Chassis & Braking
The S212 E-Class featured a sophisticated suspension system designed to provide a comfortable ride and stable handling. The front suspension utilized a multi-link independent setup with coil springs, while the rear suspension employed a multi-link independent setup. Air suspension was available as an option, further enhancing ride quality. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic stability control (ESP) were standard features, providing enhanced safety. The E 220 CDI, due to its weight, generally featured slightly thicker stabilizer bars compared to the lighter E 200 CDI models to improve body roll control.
Market Reception & Comparison
The E 220 CDI BlueEFFICIENCY was well-received by critics for its blend of fuel efficiency, comfort, and practicality. It was praised for its refined engine, smooth transmission, and spacious interior. Compared to other trims in the E-Class lineup, the E 220 CDI offered a compelling value proposition for buyers prioritizing economy and long-distance comfort. Its fuel economy figures were notably better than those of the E 350, making it an attractive option for high-mileage drivers. However, some reviewers noted that the engine lacked the outright performance of its larger counterparts.
Legacy
The OM651 engine family, including the 2.1-liter variant found in the E 220 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can accumulate high mileage without major issues. The 7G-TRONIC PLUS transmission is also generally considered reliable, although regular fluid changes are essential. In the used car market, the S212 E 220 CDI BlueEFFICIENCY remains a popular choice for buyers seeking a comfortable, efficient, and well-built estate car. Its reputation for reliability and relatively low running costs contribute to its continued desirability.
