The Mercedes-Benz CLC 230, produced from April 2008 to May 2009, was a coupe variant based on the W203 C-Class platform, internally designated CL203. Positioned as a sporty and more affordable alternative to the C-Class coupe, the CLC aimed to attract a younger demographic. The CLC 230, equipped with a 2.5-liter supercharged inline-six engine and the 7G-TRONIC automatic transmission, represented a mid-range offering within the CLC lineup, slotting between the base 180 Kompressor and the more powerful CLC 350. It was primarily marketed in Europe and other international markets, not being officially sold in the United States.

Powertrain & Engine Architecture
The CLC 230’s heart was the M272.920 2.5-liter inline-six cylinder engine. This engine featured a Lysholm-type supercharger with an intercooler, providing forced induction for increased power output. The engine utilized multi-port fuel injection and four valves per cylinder, contributing to its relatively high specific output. The M272 engine family was known for its smooth operation and refined power delivery. The 7G-TRONIC automatic transmission, a seven-speed unit, was a key component of the CLC 230. This transmission offered smooth and quick shifts, contributing to both performance and fuel efficiency. It featured a torque converter lock-up clutch to minimize slippage and improve fuel economy during cruising. The transmission was electronically controlled, adapting shift points based on driving conditions and driver input.
Driving Characteristics
The CLC 230 offered a comfortable yet engaging driving experience. The supercharged engine delivered strong acceleration, with peak torque available from 2900 rpm, making it responsive in everyday driving situations. While not as overtly sporty as the CLC 350, the 230 provided ample power for confident overtaking and highway cruising. The 7G-TRONIC transmission contributed to a relaxed driving experience, with smooth gear changes. Compared to the manual transmission options available on other CLC models, the automatic prioritized ease of use and comfort over outright performance. The rear-wheel-drive configuration provided a balanced feel, although it wasn’t as dynamically sharp as some of its competitors.
Equipment & Trim Levels
The CLC 230 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 an audio system. Interior upholstery was generally cloth or a combination of cloth and leatherette, with optional full leather available. Common optional extras included a sunroof, upgraded audio systems, navigation, and parking sensors. The dashboard layout was similar to that of the C-Class, with a focus on functionality and a relatively understated design. Trim levels varied slightly depending on the market, but generally offered a range of cosmetic and convenience upgrades.
Chassis & Braking
The CLC 230 utilized a MacPherson strut front suspension and a multi-link rear suspension, providing a good balance between ride comfort and handling. The suspension was tuned to prioritize comfort, but still offered reasonable body control. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard, enhancing safety and stability during braking. The CLC 230’s chassis was designed to provide a stable and predictable driving experience, although it wasn’t as focused on outright performance as some of its rivals.
Market Reception & Comparison
The CLC 230 received generally positive reviews from automotive critics. It was praised for its comfortable ride, refined engine, and smooth-shifting transmission. However, some critics noted that it lacked the sporty character of some competitors. Compared to the CLC 180 Kompressor, the 230 offered significantly more power and performance. In contrast to the CLC 350, the 230 was more affordable and offered better fuel economy. Fuel economy figures were respectable for a vehicle of its class, averaging around 25.8 US mpg in combined driving. Reliability was generally good, although like all Mercedes-Benz vehicles, maintenance costs could be relatively high.
Legacy
The CLC 230, while not a high-volume seller, has gained a following among enthusiasts seeking an affordable and stylish coupe. The M272 engine is known for its durability, although regular maintenance is essential. Today, well-maintained examples of the CLC 230 can be found on the used car market at relatively attractive prices. The 7G-TRONIC transmission has proven to be a reliable unit, although some units may require servicing as they age. The CLC 230 represents a unique offering from Mercedes-Benz, combining coupe styling with a comfortable ride and a refined powertrain.
