The Mercedes-Benz C-Class T-modell C 350 V6 4MATIC, produced from July 2005 to May 2007, represents a high-performance variant within the S203 facelifted C-Class range. This model combined a naturally aspirated 3.5-liter V6 engine with a five-speed automatic transmission and Mercedes-Benz’s 4MATIC all-wheel-drive system. Positioned as a premium offering, it catered to buyers seeking a blend of practicality, performance, and all-weather capability in a compact executive estate car. The C 350 4MATIC occupied the upper echelon of the S203 T-modell lineup, sitting above the more fuel-efficient four-cylinder models and the sportier, but less practical, AMG variants.

Powertrain & Engine Architecture
The heart of the C 350 4MATIC is the M272.960 3.5-liter V6 engine. This engine is a naturally aspirated, 60-degree V-engine featuring all-aluminum construction. It utilizes a three-valve-per-cylinder (two intake, one exhaust) DOHC valvetrain and a multi-port fuel injection system. The M272 engine family was known for its smooth operation and relatively high power output for its displacement. The engine’s 350 Nm (258 lb-ft) of torque is readily available from 2400-5000 rpm, contributing to strong mid-range acceleration. The five-speed automatic transmission (722.6) was a standard feature, offering smooth shifts but lacking the efficiency of more modern transmissions with a greater number of gears. The 4MATIC system employs a multi-plate clutch to distribute power between the front and rear axles, providing enhanced traction in adverse conditions.
Driving Characteristics
The C 350 4MATIC offered a noticeably more spirited driving experience than the base C-Class models. The 272 horsepower and all-wheel-drive system allowed for a 0-60 mph time of approximately 6.7 seconds. While not a dedicated sports car, the C 350 provided ample power for overtaking and highway cruising. The automatic transmission, while smooth, could feel somewhat dated compared to the more responsive transmissions found in contemporary rivals. The gear ratios were tuned for a balance of performance and fuel economy, but the lack of a sixth or seventh gear meant that engine speeds could be higher at highway speeds. The 4MATIC system provided a secure and planted feel, particularly on slippery surfaces, but added some weight compared to rear-wheel-drive models.
Equipment & Trim Levels
The C 350 4MATIC typically came well-equipped as a premium trim level. Standard features included leather upholstery, automatic climate control, a multi-function steering wheel, and a premium audio system. Optional extras included a sunroof, navigation system, heated seats, and upgraded wheels. The interior design was typical of Mercedes-Benz at the time, with a focus on luxury and comfort. The dashboard layout was functional and well-organized, although the materials used were not quite as opulent as those found in higher-end Mercedes-Benz models.
Chassis & Braking
The S203 C-Class featured an independent suspension system at all four corners. The front suspension utilized McPherson struts, while the rear employed a multi-link setup. This configuration provided a good balance of ride comfort and handling. The C 350 4MATIC was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. ABS (Anti-lock Braking System) was standard. The suspension tuning was generally geared towards comfort, but the increased weight of the 4MATIC system and the more powerful engine necessitated slightly firmer dampers and stabilizer bars compared to the base models.
Market Reception & Comparison
The C 350 4MATIC was generally well-received by automotive critics. It was praised for its strong performance, comfortable ride, and all-weather capability. However, some reviewers noted that the fuel economy was relatively poor for a car of its size and class. Compared to the C 230 Kompressor, the C 350 offered significantly more power and a more refined driving experience, but at a higher price point. Against rivals like the BMW 335i and Audi A4 3.2 quattro, the C 350 offered a more luxurious interior and a smoother ride, but lacked the ultimate sporting prowess of the BMW.
Legacy
The M272 engine family, including the 3.5-liter variant found in the C 350 4MATIC, is generally considered to be a reliable powerplant. However, like all engines, it is susceptible to certain issues, such as oil leaks and timing chain wear, particularly as mileage increases. The five-speed automatic transmission is also known to be generally durable, but may require servicing as it ages. Today, the S203 C-Class T-modell C 350 4MATIC represents a relatively affordable entry point into the world of Mercedes-Benz ownership. Well-maintained examples are sought after by enthusiasts who appreciate their blend of practicality, performance, and classic Mercedes-Benz styling.
