The Mercedes-Benz CLC 250 V6 (internally designated CL203) was a coupe produced between 2009 and 2011. Positioned as a sporty, entry-level offering within the Mercedes-Benz lineup, it was based on the W204 C-Class platform, sharing many components but offering a more compact, coupe-focused design. The CLC aimed to attract buyers seeking a premium, stylish vehicle with a focus on driving enjoyment, though it occupied a somewhat niche position in the market. This specific 250 V6 variant, equipped with the 7G-TRONIC automatic transmission, represented the highest performance level available for the CLC model.

Powertrain & Engine Architecture
The CLC 250 V6 was powered by the M272.920 2.5-liter V6 engine. This engine, a naturally aspirated powerplant, featured a 60-degree V-angle and utilized a multi-port fuel injection system. The engine produced 204 horsepower at 6,100 rpm and 245 Nm (180.7 lb-ft) of torque between 2,900 and 5,500 rpm. The engine’s double overhead camshafts (DOHC) and four valves per cylinder contributed to its relatively high specific output. The 7G-TRONIC automatic transmission, a seven-speed unit, was standard. This transmission offered smooth shifts and helped optimize fuel efficiency. The transmission’s gear ratios were tuned to balance acceleration with cruising comfort.
Driving Characteristics
The CLC 250 V6 offered a noticeable step up in performance compared to the lower-powered four-cylinder variants. While not a dedicated sports car, the V6 provided ample power for confident overtaking and enjoyable driving on winding roads. The 7G-TRONIC transmission contributed to a refined driving experience, with smooth and relatively quick gear changes. However, the automatic transmission, while convenient, didn’t offer the same level of driver engagement as a manual gearbox. The rear-wheel-drive configuration provided a balanced feel, though it could be less forgiving in slippery conditions compared to all-wheel-drive alternatives. The weight distribution, while not ideal, was manageable, and the suspension provided a comfortable ride without excessive body roll.
Equipment & Trim Levels
The CLC 250 V6 typically came with a fairly comprehensive standard equipment list. This included features such as automatic climate control, power windows and mirrors, a multi-function steering wheel, and an audio system with CD player. Upholstery was generally a combination of cloth and leatherette, with full leather options available as an upgrade. Optional extras included a sunroof, navigation system, upgraded audio systems (often from Harman Kardon), and sport seats. The interior design was generally consistent with other Mercedes-Benz models of the era, emphasizing quality materials and a functional layout.
Chassis & Braking
The CLC 250 V6 utilized an independent suspension setup at all four corners. The front suspension employed McPherson struts with a transverse stabilizer, while the rear featured a multi-link design, also with a stabilizer bar. This setup aimed to provide a balance between ride comfort and handling precision. Braking duties were handled by ventilated discs at the front and solid discs at the rear, equipped with ABS (Anti-lock Braking System). The hydraulic power steering provided a reasonably weighted feel, though it lacked the directness of some more modern steering systems.
Market Reception & Comparison
The CLC 250 V6 received mixed reviews from automotive critics. While the engine and transmission were generally praised for their smoothness and performance, the CLC’s overall design and interior quality were sometimes criticized as being less refined than other Mercedes-Benz models. Compared to the CLC 180 Kompressor or 200 CGI, the 250 V6 offered a significant performance advantage, but at a higher price point. Fuel economy was also lower with the V6 engine. Against competitors like the Audi TT or BMW 1 Series Coupe, the CLC offered a more luxurious interior but lacked the same level of sporting prowess.
Legacy
The M272 engine family, including the 2.5-liter variant found in the CLC 250 V6, is generally considered to be a reliable powerplant when properly maintained. Common issues include oil leaks and occasional problems with the balance shaft. The 7G-TRONIC transmission is also generally durable, but requires regular fluid changes to prevent issues. Today, the CLC 250 V6 represents an affordable entry point into Mercedes-Benz ownership. While not a collector’s item, well-maintained examples are sought after by enthusiasts who appreciate the combination of style, performance, and relative reliability. The CLC, while a short-lived model, offered a unique proposition in the compact coupe segment and remains a distinctive vehicle on the used car market.
