The Mercedes-Benz CLC 220 CDI, produced between April 2008 and April 2010, was a coupe variant based on the W203 C-Class platform, internally designated CL203. Positioned as a sporty, more affordable alternative to the C-Class coupe, the CLC aimed to attract a younger demographic. The 220 CDI model represented a mid-range offering within the CLC lineup, balancing performance and fuel efficiency with a diesel powertrain. It served as a bridge between the lower-powered 200 CDI and the more potent 250 CDI, offering a compelling package for buyers seeking a refined and economical coupe experience. This model was primarily sold in the European market, where diesel engines held significant popularity.

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 good fuel economy. The OM 646 featured a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A turbocharger with an intercooler was employed to boost power output and improve torque across the rev range. The engine utilized a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing breathing and contributing to its 150 horsepower and 340 Nm (250.77 lb-ft) of torque. The six-speed manual transmission was standard, providing a good balance between performance and fuel efficiency. The engine was mounted longitudinally in the front of the vehicle, driving the rear wheels.
Driving Characteristics
The CLC 220 CDI offered a comfortable and refined driving experience, prioritizing fuel efficiency and relaxed cruising over outright performance. While not a sports car, the 150 hp engine provided adequate power for everyday driving, with the 340 Nm of torque available from a low 1800 rpm offering good responsiveness. Acceleration from 0 to 60 mph took around 9.2 seconds, and the car had a top speed of 139.19 mph. Compared to the more powerful 250 CDI variant, the 220 CDI felt less urgent in acceleration, but the difference was not dramatic. The six-speed manual transmission allowed for precise gear selection, and the gear ratios were well-matched to the engine’s torque curve. The rear-wheel-drive configuration provided a balanced feel, although it wasn’t as engaging as some other rear-wheel-drive coupes.
Equipment & Trim Levels
The CLC 220 CDI typically came equipped with a reasonable level of standard features. These included air conditioning, power windows, central locking, and an audio system. Interior upholstery was generally cloth, although leather options were available. The dashboard layout was similar to that of the C-Class, with a functional and straightforward design. Optional extras included a sunroof, upgraded audio systems, navigation, and sport seats. The CLC aimed for a more youthful and stylish interior compared to the more conservative C-Class, with options for different trim finishes and color combinations.
Chassis & Braking
The CLC 220 CDI utilized a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and decent handling. The suspension was tuned for a balance between comfort and control, rather than outright sportiness. Front brakes were ventilated discs, while rear brakes were solid discs. Anti-lock Braking System (ABS) was standard. The chassis was reinforced to provide adequate rigidity for the coupe body style. The weight distribution was reasonably balanced, contributing to stable handling characteristics.
Market Reception & Comparison
The CLC 220 CDI was generally well-received by automotive critics as a stylish and economical coupe. It was praised for its fuel efficiency, comfortable ride, and refined interior. However, some critics noted that it lacked the outright performance of some of its rivals and that the interior space was somewhat limited. Compared to the 200 CDI, the 220 CDI offered a noticeable performance improvement, while still maintaining good fuel economy. Compared to the 250 CDI, it was more affordable but offered less power. The CLC competed with other compact coupes such as the BMW 1 Series Coupe and the Audi A3 Coupe.
Legacy
The OM 646 engine, found in the CLC 220 CDI, is known for its durability and reliability, provided it is properly maintained. Common issues include potential problems with the fuel injectors and the turbocharger. However, these are generally not major concerns if the vehicle has been well-cared for. In the used car market, the CLC 220 CDI represents a relatively affordable entry point into Mercedes-Benz ownership. Its fuel efficiency and comfortable ride make it a practical choice for daily commuting, while its stylish design and rear-wheel-drive configuration offer a degree of driving enjoyment. While not a collector’s item, the CLC 220 CDI remains a viable option for buyers seeking a well-rounded and reliable coupe.
