The Mercedes-Benz C-Class (W202) C 250 Turbodiesel, produced from September 1995 to June 1997, represented a significant offering in the compact executive car segment. Positioned as a premium diesel option within the W202 range, it aimed to deliver a blend of performance, fuel efficiency, and refinement. This variant occupied a middle ground in the C-Class lineup, offering more power and sophistication than the base C 220 Diesel, but remaining more accessible than the petrol-powered C 280 or the higher-performance AMG models. The W202 C-Class was Mercedes-Benz’s first foray into the compact executive market, intended to attract a younger demographic and compete with rivals like the BMW 3 Series and Audi A4.

Powertrain & Engine Architecture
The heart of the C 250 Turbodiesel was the OM 605 D 25 LA engine, a 2.5-liter inline five-cylinder diesel. This engine utilized precombustion chamber injection, a system common in Mercedes-Benz diesels of the era, known for its relatively quiet operation and good combustion efficiency. A turbocharger with an intercooler was employed to boost power output to 150 horsepower at 4400 rpm and 280 Nm (206.52 lb.-ft.) of torque between 1800 and 3600 rpm. The engine featured a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The five-cylinder configuration offered a good balance between refinement and power delivery, a characteristic Mercedes-Benz aimed for in their diesel engines. The engine’s longitudinal mounting and rear-wheel drive configuration were traditional for Mercedes-Benz at the time. The manual transmission offered five forward gears, providing a reasonable spread of ratios for both fuel economy and performance.
Driving Characteristics
The C 250 Turbodiesel offered a distinctly different driving experience compared to its petrol-powered siblings. While not as overtly sporty, it provided ample torque for comfortable cruising and effortless overtaking. The turbocharger provided a noticeable boost in power, but the engine’s peak torque was available at relatively low revs, making it feel responsive in everyday driving situations. The five-speed manual transmission allowed for precise control, but the gear ratios were geared towards economy rather than outright acceleration. Compared to the C 220 Diesel, the C 250 Turbodiesel offered a significant performance improvement, with a noticeably quicker 0-60 mph time. However, it didn’t match the responsiveness or top-end power of the C 280. The rear-wheel drive configuration provided a balanced feel, but lacked the all-weather capability of some competitors.
Equipment & Trim Levels
The C 250 Turbodiesel typically came equipped with a respectable level of standard features, reflecting its position as a premium vehicle. These included power windows, central locking, and an anti-lock braking system (ABS). Interior upholstery was typically cloth, but leather options were available. The dashboard layout was functional and well-built, typical of Mercedes-Benz interiors of the period. Optional extras included a sunroof, automatic climate control, and upgraded audio systems. The trim level could vary depending on the market, but generally, the C 250 Turbodiesel offered a comfortable and well-equipped interior.
Chassis & Braking
The W202 C-Class featured a double wishbone front suspension and an independent multi-link rear suspension, providing a comfortable ride and good handling characteristics. Stabilizer bars were fitted to both axles to reduce body roll. The C 250 Turbodiesel was equipped with ventilated disc brakes at the front and solid discs at the rear. The ABS system helped to maintain stability during braking, particularly on slippery surfaces. The suspension was tuned to provide a balance between comfort and handling, making it suitable for both city driving and long-distance journeys.
Market Reception & Comparison
The C 250 Turbodiesel was generally well-received by critics, who praised its fuel efficiency, refinement, and comfortable ride. However, some reviewers noted that it lacked the sporty character of its petrol-powered counterparts. Compared to the C 220 Diesel, the C 250 Turbodiesel offered a significant performance upgrade, making it a more appealing option for drivers who wanted more power. In terms of fuel economy, it was comparable to other diesel-powered cars in its class. Reliability was generally good, although some owners reported issues with the turbocharger and fuel injection system.
Legacy
The OM 605 engine family, including the 605.960 variant found in the C 250 Turbodiesel, is known for its durability and longevity. Properly maintained examples can still be found on the road today, testament to the engine’s robust design. In the used car market, the W202 C 250 Turbodiesel is often sought after by enthusiasts who appreciate its classic Mercedes-Benz styling and reliable diesel powertrain. While not a high-performance model, it represents a well-rounded and practical option for those seeking a comfortable and fuel-efficient compact executive car.
