The Mercedes-Benz C-Class T-modell (S203) C 240 V6 Automatic, produced from January 2001 to March 2004, represented a compelling blend of practicality and performance within the compact executive estate car segment. Positioned as a mid-range offering in the S203 series – the wagon variant of the W203 C-Class – it catered to buyers seeking a more refined and powerful alternative to the base models, without the outright cost of the high-performance AMG variants. This model occupied a space between the more economical four-cylinder options and the flagship V8, offering a smooth and capable driving experience. It was primarily marketed in Europe, where the estate body style held significant appeal, though limited numbers were available in other markets.

Powertrain & Engine Architecture
The C 240 V6 was powered by the M112.912 engine, a 2.6-liter naturally aspirated V6. This engine was a significant departure from the earlier inline-six engines used in the C-Class, offering improved smoothness and refinement. The M112 featured all-aluminum construction, three valves per cylinder (two intake, one exhaust), and a single overhead camshaft (SOHC). Fuel delivery was handled by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The engine produced 170 horsepower at 5500 rpm and 240 Nm (177 lb-ft) of torque at 4500 rpm. The engine’s longitudinal mounting allowed for rear-wheel drive, a traditional Mercedes-Benz configuration. Paired with the engine was a 5-speed automatic transmission, offering smooth shifts but lacking the responsiveness of a manual gearbox. This transmission was designed for comfort and ease of use, prioritizing a relaxed driving experience over sporty performance.
Driving Characteristics
The C 240 V6 Automatic offered a comfortable and refined driving experience. While not overtly sporty, the V6 engine provided ample power for everyday driving and overtaking maneuvers. The automatic transmission, while smooth, did exhibit some delay in downshifts, particularly when compared to the more responsive manual transmissions available in other C-Class models. The gear ratios were tuned for fuel efficiency and cruising comfort, rather than outright acceleration. Acceleration from 0-60 mph took approximately 9.4 seconds, and the top speed was electronically limited to 140 mph. The rear-wheel drive configuration provided balanced handling, but the relatively soft suspension setup prioritized ride comfort over sharp cornering. Compared to the C 320 with its larger V6, the C 240 felt less powerful, but it offered a more economical and accessible entry point into the V6 C-Class range.
Equipment & Trim Levels
The C 240 V6 Automatic typically came equipped with a respectable level of standard features. These included automatic climate control, power windows and locks, a multi-function steering wheel, and a basic audio system. Interior upholstery was typically cloth, with leather options available as an upgrade. Optional extras included a sunroof, upgraded audio systems, navigation, and heated seats. The dashboard layout was typical of the W203 C-Class, with a functional and understated design. Trim levels varied slightly depending on the market, but generally, the C 240 occupied a mid-range position, offering a step up in luxury and performance compared to the base C 180 and C 200 Kompressor models.
Chassis & Braking
The S203 C-Class T-modell featured an independent suspension system at all four wheels. The front suspension utilized McPherson struts with a transverse stabilizer bar, while the rear suspension employed a multi-link setup, also with a stabilizer bar. This configuration provided a good balance of ride comfort and handling. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock Braking System (ABS) was standard. The C 240 V6, due to its increased weight compared to the four-cylinder models, often featured slightly stiffer suspension components and larger brakes to accommodate the increased power and mass.
Market Reception & Comparison
The C 240 V6 Automatic was generally well-received by automotive critics. It was praised for its smooth engine, comfortable ride, and practical estate car body style. However, some critics noted the automatic transmission’s lack of responsiveness and the relatively high fuel consumption compared to the four-cylinder models. Compared to the C 320 V6, the C 240 offered a more affordable entry point into the V6 C-Class range, but it lacked the C 320’s extra power and performance. Against competitors like the BMW 3 Series Touring and Audi A4 Avant, the C 240 V6 offered a more luxurious and refined experience, but it was often perceived as being less engaging to drive.
Legacy
The M112 engine family, including the 2.6-liter variant found in the C 240 V6, proved to be relatively reliable. With proper maintenance, these engines can accumulate high mileage without major issues. The 5-speed automatic transmission is also generally durable, although it may require servicing over time. In the used car market, the C 240 V6 Automatic represents a good value proposition for buyers seeking a comfortable, practical, and relatively reliable estate car. However, potential buyers should be aware of the potential for age-related issues, such as worn suspension components and electrical problems. The S203 C-Class T-modell, and the C 240 V6 variant in particular, remains a popular choice for those seeking a classic Mercedes-Benz estate car experience.
