The Mercedes-Benz CLC 220 CDI Automatic, produced between April 2008 and April 2010, represented a compelling entry point into the Mercedes-Benz coupe range. Based on the CLC (CL203) platform – a derivative of the W203 C-Class – the 220 CDI offered a blend of sporty styling, diesel efficiency, and Mercedes-Benz luxury. This variant occupied a mid-range position within the CLC lineup, slotting below the more powerful petrol-fueled models like the CLC 350 and above the base CLC 180 Kompressor. It was primarily marketed in Europe and other regions where diesel engines were favored for their fuel economy and torque characteristics.

Powertrain & Engine Architecture
The CLC 220 CDI was powered by the OM 646.963, a 2.1-liter inline-four cylinder diesel engine. This engine was a mainstay in the Mercedes-Benz lineup during the mid-2000s and early 2010s, known for its robust construction and relatively simple design. It featured a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A turbocharger with an intercooler was employed to boost power and torque, mitigating the typical turbo lag associated with smaller displacement engines. The engine utilized a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and contributing to its power output. The automatic transmission paired with this engine was a five-speed unit, designed to provide smooth shifts and efficient power delivery. While not the sportiest transmission available, it was well-suited to the engine’s torque characteristics and the intended cruising nature of the CLC.
Driving Characteristics
The CLC 220 CDI Automatic offered a comfortable and refined driving experience. The 340 Nm (250.77 lb-ft) of torque available from 1800 rpm provided ample pulling power for everyday driving and overtaking maneuvers. While the 150 horsepower output wasn’t particularly high, the engine felt responsive and capable. The five-speed automatic transmission, while not offering the quickest shifts, was generally smooth and predictable. Compared to the manual transmission versions of the CLC 220 CDI, the automatic offered greater convenience, particularly in urban traffic. However, it did result in a slight decrease in fuel economy and a marginally slower 0-60 mph time. Compared to the more powerful CLC 350, the 220 CDI prioritized fuel efficiency and torque over outright speed and acceleration.
Equipment & Trim Levels
The CLC 220 CDI Automatic typically came equipped with a respectable level of standard features. These included automatic climate control, power windows and mirrors, a multi-function steering wheel, and a basic audio system. Interior upholstery was generally cloth, although leather options were available. Optional extras included a sunroof, upgraded audio systems, navigation, and sport seats. Trim levels varied slightly depending on the market, but generally offered packages that bundled together popular options. The overall interior design was functional and well-built, reflecting Mercedes-Benz’s commitment to quality.
Chassis & Braking
The CLC (CL203) chassis featured independent suspension all around, with MacPherson struts at the front and multi-link suspension at the rear. This setup provided a good balance between ride comfort and handling. The 220 CDI variant typically used ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock Braking System (ABS) was standard. The suspension was tuned to provide a comfortable ride, but it also offered reasonable body control during cornering. Stabilizer bars were fitted front and rear to reduce body roll.
Market Reception & Comparison
The CLC 220 CDI Automatic was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some critics noted that the styling was somewhat bland and that the handling wasn’t as sharp as some of its rivals. Compared to other trims in the CLC lineup, the 220 CDI offered a compelling value proposition for buyers who prioritized fuel economy and torque over outright performance. It was a popular choice for those who frequently drove long distances or in urban environments.
Legacy
The OM 646 engine family, including the 646.963 found in the CLC 220 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. The CLC 220 CDI Automatic remains a relatively affordable and practical used car option today. While it may not offer the latest technology or the most exciting driving experience, it provides a comfortable, efficient, and reliable mode of transportation. Parts availability is generally good, and maintenance costs are reasonable, making it a sensible choice for budget-conscious buyers seeking a Mercedes-Benz coupe.
