The Mercedes-Benz E-Class Coupe (C207) E 350 CGI BlueEFFICIENCY, produced from May 2009 to April 2011, represented a sophisticated blend of performance and efficiency within the broader C207 coupe range. Positioned as a mid-range offering, it slotted between the entry-level E 250 CGI and the more potent E 500 models. This variant aimed to deliver a refined grand touring experience, appealing to buyers seeking a balance of power, comfort, and fuel economy in a stylish two-door package. The C207 generation itself was a significant departure from its predecessor, offering a more dynamic design and improved interior quality, building upon the success of the W212 E-Class sedan.

Powertrain & Engine Architecture
The heart of the E 350 CGI BlueEFFICIENCY was the M272.982 or M272.984 3.5-liter naturally aspirated V6 engine. This engine featured direct fuel injection (CGI – Charged Gasoline Injection) and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The direct injection system allowed for precise fuel delivery, improving both power and efficiency. The engine produced 292 horsepower at 6400 rpm and 365 Nm (269.21 lb-ft) of torque between 3000 and 5100 rpm. The ‘BlueEFFICIENCY’ designation indicated the inclusion of various fuel-saving technologies, such as optimized engine management and reduced friction components. The engine was longitudinally mounted in the front of the vehicle, driving the rear wheels. Paired with the engine was the 7G-TRONIC seven-speed automatic transmission, known for its smooth shifting and wide gear ratios. This transmission contributed to both performance and fuel economy, allowing the engine to operate efficiently at highway speeds.
Driving Characteristics
The E 350 CGI BlueEFFICIENCY offered a comfortable and refined driving experience. The 7G-TRONIC transmission provided seamless gear changes, contributing to a smooth and effortless feel. While not as overtly sporty as some of its rivals, the E 350 delivered ample power for confident overtaking and cruising. The 0-60 mph acceleration time of around 6 seconds was respectable for the era. Compared to the E 500, the E 350 offered a more balanced driving experience, with less emphasis on outright power and more on refinement. The gear ratios of the 7G-TRONIC were tuned to prioritize fuel efficiency at cruising speeds, while still providing quick response when needed. Compared to a manual transmission equipped E-Class, the automatic offered greater convenience, particularly in urban driving, but at the expense of some driver engagement.
Equipment & Trim Levels
The E 350 CGI BlueEFFICIENCY came standard with a generous array of features, including leather upholstery, automatic climate control, a premium sound system, and power-adjustable front seats. Optional extras included a panoramic sunroof, a navigation system, and advanced driver-assistance systems such as adaptive cruise control and lane-keeping assist. Interior trim options allowed for customization, with choices in wood veneers and aluminum accents. The dashboard layout was typical of Mercedes-Benz, emphasizing elegance and functionality. The standard upholstery was typically MB-Tex artificial leather, with genuine leather available as an upgrade.
Chassis & Braking
The C207 E-Class Coupe featured a sophisticated chassis design, with a multi-link independent suspension at all four corners. This suspension setup provided a comfortable ride while maintaining good handling characteristics. The E 350 typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard. The rear suspension geometry was tuned to accommodate the coupe’s slightly different weight distribution compared to the sedan. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The E 350 CGI BlueEFFICIENCY was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and luxurious interior. However, some reviewers noted that it lacked the sporting character of some of its competitors, such as the BMW 3 Series Coupe. Fuel economy was considered good for a vehicle in its class, although it didn’t quite match the efficiency of diesel-powered alternatives. Compared to the E 250 CGI, the E 350 offered a significant performance upgrade, while remaining more affordable than the range-topping E 500. Reliability was generally good, although some owners reported minor issues with the electronic systems.
Legacy
The M272 engine family, including the version found in the E 350 CGI BlueEFFICIENCY, has proven to be relatively reliable over the long term, provided it receives regular maintenance. The 7G-TRONIC transmission is also known for its durability. Today, the C207 E 350 Coupe represents a compelling value in the used car market, offering a blend of luxury, performance, and reliability at an affordable price. While not a collector’s item, it remains a desirable option for buyers seeking a stylish and comfortable grand tourer. Common maintenance items include regular oil changes, coolant flushes, and inspection of the suspension components. The direct injection system requires periodic cleaning to prevent carbon buildup.
