The Mercedes-Benz C-Class (W203) facelift C 220 CDI Automatic, produced from April 2005 to March 2007, represented a significant offering in the compact executive car segment. This variant, powered by a 2.2-liter turbocharged diesel engine producing 150 horsepower, was positioned as a fuel-efficient and comfortable option within the W203 range, appealing to buyers prioritizing economy and refinement over outright performance. It sat between the lower-powered C 200 CDI and the more potent C 270 CDI in the lineup, offering a balance of performance and running costs. The introduction of a Diesel Particulate Filter (DPF) was a key feature, aligning the vehicle with increasingly stringent European emission standards.

Powertrain & Engine Architecture
The heart of the C 220 CDI was the OM 646.963, a 2.2-liter inline-four cylinder diesel engine. This engine utilized common rail direct injection, delivering fuel at extremely high pressure for improved combustion efficiency and reduced emissions. A turbocharger with an intercooler further enhanced performance, boosting power output to 150 horsepower and 340 Nm (250.77 lb.-ft.) of torque. The engine featured a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing gas flow. The five-speed automatic transmission, a staple in Mercedes-Benz vehicles of the era, was specifically tuned to complement the engine’s torque characteristics, prioritizing smooth shifts and fuel economy. The inclusion of a Diesel Particulate Filter (DPF) was crucial for meeting Euro 4 emission standards, trapping soot particles and periodically regenerating to maintain functionality.
Driving Characteristics
The C 220 CDI Automatic offered a comfortable and refined driving experience. While not a performance-oriented variant, the 340 Nm of torque provided ample power for everyday driving and overtaking maneuvers. Acceleration from 0 to 100 km/h (0-62 mph) took approximately 10.3 seconds. The automatic transmission, while smooth, wasn’t particularly quick to respond, and lacked the engagement of a manual gearbox. Compared to the C 200 CDI, the C 220 CDI offered noticeably more power, while the C 270 CDI provided a more substantial performance upgrade, but at the cost of increased fuel consumption. The rear-wheel drive configuration contributed to balanced handling, although it could be less forgiving in slippery conditions compared to front-wheel drive alternatives.
Equipment & Trim Levels
The C 220 CDI Automatic typically came equipped with a respectable level of standard features, including automatic climate control, power windows, central locking, and an audio system. Interior upholstery was generally cloth, with leather options available as an upgrade. Trim levels varied depending on the market, but commonly included options such as alloy wheels, a sunroof, and parking sensors. The facelifted W203 models benefited from revised interior trim and updated infotainment systems compared to pre-facelift versions.
Chassis & Braking
The W203 C-Class featured an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This configuration provided a good balance of ride comfort and handling. The C 220 CDI was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock Braking System (ABS) was standard, enhancing braking performance and stability. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The C 220 CDI Automatic was well-received by critics and consumers alike, praised for its fuel efficiency, comfortable ride, and refined interior. It offered a compelling alternative to rivals such as the BMW 320d and Audi A4 2.0 TDI. Fuel economy figures of around 6.8-6.9 l/100 km (34.6-34.1 US mpg) were particularly attractive to buyers. However, some reviewers noted the automatic transmission could feel sluggish at times. Reliability was generally good, although the DPF system could be prone to issues if not properly maintained.
Legacy
The OM 646 engine family, including the 2.2-liter variant found in the C 220 CDI, proved to be a durable and reliable powerplant. While DPF maintenance can be a concern on older examples, these engines are generally capable of high mileage with proper care. Today, the W203 C 220 CDI Automatic represents an affordable entry point into Mercedes-Benz ownership, offering a comfortable and economical driving experience. Its relatively simple mechanicals and readily available parts make it a popular choice for enthusiasts and budget-conscious buyers.
