The Mercedes-Benz C-Class T-modell (S203) C 240 V6 4MATIC Automatic, produced from April 2004 to May 2005, represents a compelling blend of practicality and performance within the C-Class range. Positioned as a mid-range offering in the facelifted S203 series, this variant combined a smooth, naturally aspirated V6 engine with the security and all-weather capability of Mercedes-Benz’s 4MATIC all-wheel-drive system. It catered to buyers seeking a versatile, comfortable, and relatively powerful station wagon for family use or active lifestyles. The S203 generation, launched in 2000, was Mercedes-Benz’s entry into the compact executive estate market, aiming to compete with established rivals like the BMW Touring and Audi Avant.

Powertrain & Engine Architecture
The C 240 V6 4MATIC utilized Mercedes-Benz’s M112.916 engine, a 2.6-liter naturally aspirated V6. This engine was a significant departure from earlier inline-six designs, offering improved smoothness and packaging. The M112 featured a magnesium block with aluminum cylinder heads, contributing to a relatively lightweight construction. Fuel delivery was handled by a multi-port fuel injection system, and the engine employed a single overhead camshaft (SOHC) design per bank of cylinders. The 4MATIC system was a full-time all-wheel-drive system, utilizing a center differential to distribute power between the front and rear axles. The 5-speed automatic transmission (typically the 722.6) was chosen for its smooth operation and suitability for comfortable cruising. This transmission featured electronically controlled shifting and adaptive learning to optimize gear selection based on driving style.
Driving Characteristics
The C 240 V6 4MATIC offered a refined and comfortable driving experience. With 170 horsepower and 240 Nm (177 lb-ft) of torque, acceleration was adequate, reaching 60 mph in approximately 9.9 seconds. While not a sports car, the V6 provided sufficient power for everyday driving and overtaking maneuvers. The automatic transmission contributed to a relaxed driving style, with smooth gear changes. The 4MATIC system provided enhanced traction, particularly in inclement weather, making it a secure and predictable vehicle to drive year-round. Compared to the more powerful C 320 or the diesel-powered C 220 CDI, the C 240 offered a balance between performance and fuel economy, though it lacked the outright punch of its siblings.
Equipment & Trim Levels
The C 240 V6 4MATIC typically came standard with features such as automatic climate control, power windows and locks, a multi-function steering wheel, and a basic audio system. Upholstery was generally cloth, with leather options available as an upgrade. Optional extras included a sunroof, upgraded audio systems, navigation, and parking sensors. The facelifted S203 models also benefited from revised interior trim and updated switchgear compared to pre-facelift versions. The overall interior ambiance was one of understated luxury, typical of Mercedes-Benz.
Chassis & Braking
The S203 C-Class featured an independent suspension system all around, with McPherson struts at the front and a multi-link setup at the rear. This configuration provided a good balance between ride comfort and handling. The C 240 V6 4MATIC was equipped with ventilated disc brakes at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The C 240 V6 4MATIC was generally well-received by automotive critics as a practical and comfortable station wagon. It was praised for its smooth engine, refined ride, and the added security of all-wheel drive. However, some reviewers noted that its performance was not as exhilarating as some of its rivals. Compared to the C 220 CDI, the C 240 offered less fuel economy but more power. Against the C 320, it provided a more affordable entry point into the C-Class range, albeit with less performance. Fuel economy figures were typical for a V6 engine of this era, averaging around 20 mpg combined.
Legacy
The M112 engine family, including the M112.916 found in the C 240, is generally considered to be a reliable powerplant. With proper maintenance, these engines can accumulate high mileage. The 5-speed automatic transmission is also known for its durability. Today, the S203 C-Class T-modell C 240 V6 4MATIC represents an affordable entry point into Mercedes-Benz ownership. While not a collector’s item, well-maintained examples are sought after by those looking for a practical, comfortable, and relatively reliable station wagon. Common issues to look for include wear and tear on suspension components, electrical gremlins, and potential oil leaks from the engine.
