The Mercedes-Benz E-Class Coupe (C207) facelift, produced from June 2013 to July 2014, represented a refined iteration of the second-generation E-Class coupe. The E 350 BlueTEC V6, equipped with the 7G-TRONIC PLUS automatic transmission, occupied a mid-to-upper position within the C207 lineup, offering a blend of performance, efficiency, and luxury. This variant was positioned above the E 250 CDI and below the more powerful E 500 models, targeting buyers seeking a sophisticated grand tourer with strong diesel torque. It was a key offering in European markets where diesel engines were highly favored, and represented a more economical alternative to the gasoline-powered E 500 while still delivering a premium driving experience.

INTRODUCTION
The Mercedes-Benz E 350 BlueTEC Coupe (C207, facelift 2013) was a two-door, four-seater luxury coupe powered by a 3.0-liter turbocharged diesel V6 engine. Produced between June 2013 and July 2014, it represented a mid-cycle refresh of the C207 E-Class Coupe, bringing updated styling, improved efficiency, and enhanced technology. This variant was built on the W207 platform, shared with the E-Class sedan and wagon, but distinguished itself with its sleeker profile and focus on a more dynamic driving experience. The “BlueTEC” designation indicated the use of advanced emissions control technology, including AdBlue injection, to meet stringent Euro 6 emission standards.
Powertrain & Engine Architecture
At the heart of the E 350 BlueTEC Coupe lay the OM 642.838 3.0-liter V6 diesel engine. This engine featured a common-rail direct fuel injection system, delivering fuel at extremely high pressure for optimized combustion. A single turbocharger with variable geometry turbine (VGT) and an intercooler boosted power and torque. The engine utilized a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The 7G-TRONIC PLUS seven-speed automatic transmission was standard, offering smooth and efficient gear changes. This transmission featured a torque converter lock-up clutch to minimize slippage and improve fuel economy. The transmission was tuned for a balance of comfort and responsiveness, with selectable driving modes influencing shift points. The engine also incorporated a Start & Stop system to further reduce fuel consumption in urban driving conditions, and a particulate filter to minimize emissions.
Driving Characteristics
The E 350 BlueTEC Coupe delivered a refined and effortless driving experience. The 620 Nm (457 lb-ft) of torque, available from a low 1600 rpm, provided strong acceleration and excellent overtaking capability. While not as overtly sporty as the gasoline-powered E 500, the diesel engine offered ample power for comfortable cruising and spirited driving. The 7G-TRONIC PLUS transmission contributed to smooth acceleration, and the gear ratios were well-matched to the engine’s torque curve. Compared to the manual transmission options available on other E-Class models, the automatic prioritized comfort and ease of use. The rear-wheel drive configuration provided a balanced feel, although it wasn’t as engaging as all-wheel drive variants. The electronically limited top speed of 250 km/h (155 mph) was more than sufficient for most driving situations.
Equipment & Trim Levels
The E 350 BlueTEC Coupe came well-equipped as standard. Typical features included leather upholstery, automatic climate control, a premium audio system, and a host of safety features such as ABS, ESP, and multiple airbags. The interior featured high-quality materials and a sophisticated design. Optional extras included a panoramic sunroof, upgraded leather packages, a driver assistance package (including adaptive cruise control and lane keeping assist), and a more powerful audio system. The dashboard layout was similar to other C207 E-Class models, with a central display screen controlling infotainment functions. Exterior styling cues included distinctive LED headlights and taillights, and a choice of alloy wheel designs.
Chassis & Braking
The C207 E-Class Coupe featured a sophisticated chassis designed for both comfort and handling. The front suspension utilized a multi-link coil spring setup with a transverse stabilizer bar, while the rear suspension employed an independent multi-link spring suspension, also with a stabilizer bar. This configuration provided a comfortable ride while minimizing body roll during cornering. Braking duties were handled by ventilated discs on all four wheels, providing ample stopping power. The anti-lock braking system (ABS) and electronic stability program (ESP) enhanced safety and control. Steering was via a rack and pinion system with electric power assistance.
Market Reception & Comparison
The E 350 BlueTEC Coupe was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and luxurious interior. The diesel engine’s fuel economy was a significant selling point, particularly in Europe. Compared to the E 250 CDI, the E 350 BlueTEC offered significantly more power and torque, resulting in a more engaging driving experience. However, it was more expensive than the E 250 CDI. Compared to the E 500, the E 350 BlueTEC offered a more economical alternative, albeit with slightly less outright performance. Reliability was generally good, although diesel particulate filter issues could occasionally arise with infrequent long-distance driving.
Legacy
The OM 642 engine family, including the OM 642.838 found in the E 350 BlueTEC, is known for its durability and longevity. With proper maintenance, these engines can reliably exceed 200,000 miles. The 7G-TRONIC PLUS transmission is also generally reliable, although fluid changes are crucial for maintaining its performance. In the used car market, the E 350 BlueTEC Coupe represents a compelling value proposition, offering a luxurious and well-equipped coupe at a relatively affordable price. However, potential buyers should be aware of the potential for diesel particulate filter issues and ensure that the vehicle has been properly maintained. The C207 E-Class Coupe, and particularly the E 350 BlueTEC variant, remains a desirable choice for those seeking a sophisticated and comfortable grand tourer.
