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 alternative to the C-Class sedan, the CLC aimed to attract a younger demographic with its coupe styling and relatively accessible price point. The CLC 230 represented a mid-range offering within the CLC lineup, slotting between the base CLC 180 Kompressor and the higher-performance CLC 350. It combined a supercharged 2.5-liter inline-six engine with a six-speed manual transmission, offering a balance of performance and fuel efficiency. This model 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 engine. This engine featured a Lysholm-type supercharger with an intercooler, providing forced induction for increased power output. The supercharger, unlike a turbocharger, is mechanically driven by the engine’s crankshaft, offering immediate boost response. Fuel delivery was handled by a multi-port fuel injection system, ensuring precise fuel metering for optimal combustion. The engine boasted four valves per cylinder, contributing to its efficient breathing and power delivery. The six-speed manual transmission was a Getrag unit, known for its robust construction and precise shift feel. This transmission was chosen to complement the engine’s power output and provide a more engaging driving experience compared to the available automatic option.
Driving Characteristics
The CLC 230 with the manual transmission offered a spirited driving experience. The supercharged engine delivered strong low-end torque, making it responsive in everyday driving situations. Acceleration from 0 to 60 mph was achieved in around 8 seconds, respectable for its class. The manual gearbox allowed for precise control over the engine’s power band, enabling drivers to fully exploit the engine’s capabilities. Compared to the CLC 180 Kompressor, the 230 offered a significant performance upgrade, while remaining more accessible and fuel-efficient than the range-topping CLC 350. The rear-wheel-drive configuration contributed to a balanced chassis and predictable handling, although it lacked the all-weather capability of all-wheel-drive systems found in some competitors.
Equipment & Trim Levels
The CLC 230 typically came equipped with features such as air conditioning, power windows, power mirrors, and a basic audio system. Upholstery was generally cloth, although leather options were available. Optional extras included a sunroof, upgraded audio systems, navigation, and sport seats. The interior design was largely carried over from the W203 C-Class, offering a functional and relatively understated aesthetic. The CLC 230 aimed for a balance between affordability and comfort, offering a decent level of equipment without the premium price tag of the CLC 350.
Chassis & Braking
The CLC 230 utilized a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and competent handling. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking. The suspension was tuned to provide a balance between comfort and sportiness, offering a reasonably compliant ride while maintaining good body control. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The CLC 230 received mixed reviews from automotive critics. While the engine was praised for its performance and responsiveness, some critics found the interior design to be dated and the overall driving experience to be less refined than that of its competitors, such as the Audi TT and BMW 1 Series Coupe. Fuel economy was considered reasonable for a vehicle of its class, averaging around 25.6 US mpg in combined driving. Reliability was generally good, although some owners reported issues with the supercharger and electrical components. Compared to the CLC 180 Kompressor, the 230 offered a worthwhile performance upgrade, justifying the higher price. However, the CLC 350 provided a more substantial performance boost, albeit at a significantly higher cost.
Legacy
The Mercedes-Benz CLC 230, while not a sales success, remains a relatively affordable entry point into the Mercedes-Benz coupe world. The M272 engine, when properly maintained, is known for its durability. Today, the CLC 230 is sought after by enthusiasts who appreciate its unique styling and engaging driving experience. Parts availability is generally good, although some specialized components may be difficult to find. The CLC 230 represents a unique chapter in Mercedes-Benz history, offering a sporty and accessible coupe option that appealed to a specific segment of the market.
