2011-2013 Mercedes-Benz E-class Coupe (C207) E 300 BlueEFFICIENCY V6 (252 Hp) 7G-TRONIC PLUS

Technical Specifications

The Mercedes-Benz E-Class Coupe (C207), produced from 2009 to 2013, represented a significant step forward in design and driving dynamics for the E-Class range. The E 300 BlueEFFICIENCY variant, featuring a 3.5-liter naturally aspirated V6 engine paired with the 7G-TRONIC PLUS seven-speed automatic transmission, was introduced in April 2011. This model aimed to provide a refined and efficient grand touring experience, appealing to buyers who prioritized comfort and style alongside respectable performance. It sat comfortably in the middle of the C207 coupe lineup, positioned above the four-cylinder E 250 and below the more powerful E 550.

Powertrain & Engine Architecture

The heart of the E 300 BlueEFFICIENCY is the M 276.957 3.5-liter V6 engine. This engine utilizes direct fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine’s “BlueEFFICIENCY” designation signifies the inclusion of various fuel-saving technologies, including optimized combustion chamber design and reduced internal friction. The engine produces 252 horsepower at 6500 rpm and 340 Nm (250.77 lb-ft) of torque between 3500 and 4500 rpm. The 7G-TRONIC PLUS automatic transmission is a seven-speed torque converter automatic known for its smooth shifting and efficiency. It features a wide range of gear ratios designed to optimize both acceleration and fuel economy. The transmission also includes a manual shift mode for more driver involvement.

Driving Characteristics

The E 300 BlueEFFICIENCY offered a comfortable and refined driving experience. While not overtly sporty, the V6 engine provided ample power for effortless cruising and confident overtaking. The 7G-TRONIC PLUS transmission contributed to smooth and seamless gear changes, enhancing the overall sense of refinement. Compared to the base E 250, the E 300 offered a noticeable improvement in acceleration and overall responsiveness. However, it lacked the outright performance of the E 550, which featured a larger V8 engine. The automatic transmission, while convenient, did result in a slight reduction in fuel economy compared to the available six-speed manual transmission (though the manual was less common in this configuration). The gear ratios were tuned for a balance between acceleration and fuel efficiency, prioritizing comfortable long-distance driving.

Equipment & Trim Levels

The E 300 BlueEFFICIENCY came standard with a generous array of features, including leather upholstery, dual-zone automatic climate control, a premium sound system, and a power-adjustable driver’s seat. Interior trim options included various wood veneers and aluminum accents. Optional extras included a panoramic sunroof, a navigation system, heated and ventilated front seats, and a driver assistance package featuring adaptive cruise control and lane-keeping assist. The dashboard layout was typical of Mercedes-Benz at the time, featuring a blend of classic elegance and modern technology. 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 suspension system designed to provide a comfortable ride and precise handling. The front suspension utilized a multi-link setup with coil springs and a transverse stabilizer bar, while the rear suspension employed an independent multi-link spring suspension, also with a stabilizer bar. Braking duties were handled by ventilated disc brakes on all four wheels. ABS (Anti-lock Braking System) was standard. The E 300’s weight distribution was well-balanced, contributing to its stable and predictable handling characteristics. The suspension tuning was geared towards comfort, but still provided adequate control in spirited driving situations.

Market Reception & Comparison

The E 300 BlueEFFICIENCY was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, and comfortable ride. Critics noted that it offered a good balance between performance and fuel economy, making it a practical choice for everyday driving. Compared to the E 250, the E 300 was considered a worthwhile upgrade for buyers who prioritized performance. However, some reviewers felt that the E 550 offered a more engaging driving experience. Fuel economy figures were competitive for its class, averaging around 33.6 mpg (combined NEDC). Reliability was generally good, although some owners reported minor issues with electronic components.

Legacy

The M 276 V6 engine family, including the version used in the E 300 BlueEFFICIENCY, proved to be a reliable and durable powertrain. These engines are known for their longevity and relatively low maintenance costs. On the used car market, the C207 E 300 BlueEFFICIENCY remains a popular choice for buyers seeking a stylish and comfortable coupe. While not as sought-after as some of the more powerful E-Class variants, it offers a compelling combination of value, refinement, and reliability. Properly maintained examples continue to provide years of enjoyable driving.
