The Mercedes-Benz C-Class T-modell (S204) C 200 CGI BlueEFFICIENCY, equipped with the 5G-TRONIC automatic transmission, was a variant produced between 2009 and 2011. Positioned as a mid-range offering within the S204 estate (wagon) lineup, it aimed to balance fuel efficiency with respectable performance. This model represented Mercedes-Benz’s attempt to modernize the C-Class range with direct-injection technology and improved aerodynamics, falling between the base C 180 K and the more powerful C 250 CGI models. It was primarily marketed in Europe, where the estate body style is particularly popular, offering a practical and relatively economical option for families and individuals needing ample cargo space.

Powertrain & Engine Architecture
The C 200 CGI BlueEFFICIENCY utilized the M 271.860 1.8-liter inline-four cylinder engine. This engine was a significant departure from earlier Mercedes-Benz four-cylinder designs, incorporating direct fuel injection and a turbocharger with an intercooler. The direct injection system, a key component of the CGI (Compact High Efficiency Injection) technology, allowed for more precise fuel delivery, improved combustion efficiency, and reduced emissions. The engine featured a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for increased power output. The 5G-TRONIC automatic transmission, a five-speed torque converter automatic, was specifically tuned to work with the engine’s characteristics, prioritizing smooth shifts and fuel economy. This transmission was known for its relatively quick response and adaptability to different driving conditions.
Driving Characteristics
The 184 horsepower and 199 lb-ft of torque delivered by the C 200 CGI BlueEFFICIENCY provided adequate, though not exhilarating, performance. Acceleration from 0 to 60 mph took around 8 seconds, and the top speed was 139.81 mph. Compared to the more powerful C 250 CGI, the C 200 felt noticeably less responsive, particularly during overtaking maneuvers. The 5G-TRONIC transmission, while smooth, could sometimes feel hesitant when downshifting, especially in situations requiring rapid acceleration. The gear ratios were optimized for fuel efficiency rather than outright performance. Drivers accustomed to manual transmissions or the quicker-shifting 7G-TRONIC found in higher-spec C-Class models often noted the difference in responsiveness. However, for everyday driving and commuting, the C 200 CGI offered a comfortable and refined experience.
Equipment & Trim Levels
The C 200 CGI BlueEFFICIENCY typically came standard with features such as automatic climate control, power windows and mirrors, a multi-function steering wheel, and an audio system with CD player. Upholstery was generally cloth, though leather options were available as upgrades. Optional extras included a sunroof, navigation system, parking sensors, and upgraded audio systems. The “BlueEFFICIENCY” designation indicated the inclusion of fuel-saving technologies such as start-stop functionality (depending on the specific market and year) and aerodynamic enhancements. Trim levels were relatively simple, with most customization occurring through the selection of optional packages.
Chassis & Braking
The S204 C-Class featured an independent suspension system, 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 200 CGI, being a mid-range model, typically came equipped with ventilated disc brakes at the front and solid disc brakes 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. The suspension tuning was generally geared towards comfort, making it a pleasant vehicle for long journeys.
Market Reception & Comparison
The C 200 CGI BlueEFFICIENCY was generally well-received by automotive critics as a practical and economical option within the C-Class range. Its fuel economy figures were competitive for its class, and the direct-injection engine offered a noticeable improvement in efficiency compared to older Mercedes-Benz engines. However, some reviewers criticized its lack of outright performance, particularly when compared to the C 250 CGI or the diesel-powered C 220 CDI. The 5G-TRONIC transmission, while smooth, was also seen as somewhat dated compared to the more modern 7G-TRONIC available on other models. In terms of reliability, the M 271 engine proved to be generally robust, although some owners reported issues with the turbocharger and fuel injectors over the long term.
Legacy
The C 200 CGI BlueEFFICIENCY represents an important step in Mercedes-Benz’s efforts to improve fuel efficiency and reduce emissions. The M 271 engine, with its direct injection and turbocharging technology, paved the way for future generations of Mercedes-Benz engines. On the used car market, these models are generally considered to be a good value, offering a comfortable and well-equipped vehicle at a relatively affordable price. However, potential buyers should be aware of the potential for issues with the turbocharger and fuel injectors, and a thorough inspection by a qualified mechanic is recommended before purchase. The S204 C-Class estate, in general, remains a popular choice for those seeking a practical and stylish wagon.
