The Mercedes-Benz CLC 250 V6, produced from 2009 to 2011, was a performance-oriented variant of the CLC (CL203) coupe. Positioned as a mid-range offering within the CLC lineup, it aimed to bridge the gap between the more economical base models and the higher-performance AMG variants. The CLC itself was a compact, three-door coupe based on the W203 C-Class platform, intended to appeal to a younger demographic seeking a sporty and stylish vehicle. The 250 V6 distinguished itself with a naturally aspirated V6 engine, offering a significant power upgrade over the four-cylinder options.

Powertrain & Engine Architecture
The heart of the CLC 250 V6 is the M 272.920 2.5-liter V6 engine. This engine, part of Mercedes-Benz’s M272 family, is a naturally aspirated, 24-valve (four valves per cylinder) powerplant. It utilizes a multi-port fuel injection system and a double overhead camshaft (DOHC) valvetrain. The engine’s design emphasizes smooth power delivery and refinement, rather than outright peak horsepower. The standard 6-speed manual transmission provided drivers with direct control over the engine’s power. The engine’s longitudinal mounting and rear-wheel-drive configuration contribute to the car’s balanced handling characteristics.
Driving Characteristics
The CLC 250 V6 offered a noticeable step up in performance compared to the base CLC models equipped with four-cylinder engines. The V6’s 204 horsepower and 245 Nm (180.7 lb-ft) of torque provided brisk acceleration, with a 0-60 mph time of around 8 seconds. While not a sports car in the purest sense, the CLC 250 V6 delivered a satisfying driving experience, particularly on winding roads. The manual transmission allowed for precise gear selection, maximizing the engine’s power band. The rear-wheel-drive layout contributed to a balanced feel, although traction could be a concern in wet conditions. Compared to the more powerful CLC 350, the 250 V6 offered a more manageable and fuel-efficient driving experience.
Equipment & Trim Levels
The CLC 250 V6 typically came equipped with a reasonable level of standard features, including air conditioning, power windows and locks, and a basic audio system. Interior upholstery was generally cloth, although leather options were available. Dashboard trim could vary depending on the specific package selected. Optional extras included a sunroof, upgraded audio systems, navigation, and sport seats. The CLC 250 V6 often served as a platform for various option packages, allowing buyers to customize the car to their preferences.
Chassis & Braking
The CLC 250 V6 utilized an independent suspension system at all four wheels. The front suspension employed McPherson struts with a transverse stabilizer bar, while the rear featured a multi-link setup, also with a stabilizer bar. This suspension configuration 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 an Anti-lock Braking System (ABS). The chassis was designed to be relatively lightweight, contributing to the car’s agility.
Market Reception & Comparison
The CLC 250 V6 was generally well-received by automotive critics, who praised its smooth engine, balanced handling, and stylish design. However, some reviewers noted that the interior quality was not quite up to par with other Mercedes-Benz models. Compared to the four-cylinder CLC variants, the 250 V6 offered a significant performance upgrade, but at a higher price point. Fuel economy was reasonable for a V6 engine, but not exceptional. The CLC 250 V6 competed with other compact coupes, such as the BMW 1 Series Coupe and the Audi TT.
Legacy
The M 272 V6 engine used in the CLC 250 V6 is generally considered to be a reliable powerplant, provided it receives regular maintenance. Common issues include oil leaks and occasional problems with the ignition system. The CLC 250 V6 has maintained a modest following in the used car market, appealing to buyers seeking a stylish and relatively affordable Mercedes-Benz coupe. Parts availability is generally good, although some components may be becoming increasingly difficult to find. The CLC 250 V6 represents a unique offering in Mercedes-Benz’s history, combining a sporty coupe body style with a refined V6 engine.
