INTRODUCTION
The Mercedes-Benz E 350 BlueTEC Cabriolet (A207, facelift) offered a sophisticated open-top experience powered by a robust diesel engine. Introduced in June 2013 and continuing through July 2014, this variant was built on the W207 platform, specifically the A207 Cabriolet body style. The facelift brought cosmetic and technological updates, enhancing the car’s appeal. Positioned as a premium offering, the E 350 BlueTEC aimed to attract buyers seeking a blend of luxury, performance, and fuel efficiency in a convertible package. It served as a diesel alternative to the gasoline-powered E-Class Cabriolets, catering to European markets where diesel engines were highly favored.
Powertrain & Engine Architecture
At the heart of the E 350 BlueTEC Cabriolet lies the OM642.838 3.0-liter V6 diesel engine. This engine is a hallmark of Mercedes-Benz diesel technology, known for its durability and refinement. It features a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine utilizes a single turbocharger with an intercooler to boost power and torque. The valvetrain employs a double overhead camshaft (DOHC) design with four valves per cylinder, maximizing breathing efficiency. The 7G-TRONIC PLUS automatic transmission, a seven-speed unit, was standard. This transmission is renowned for its smooth shifts and efficiency, contributing to the car’s overall refinement. The transmission’s gear ratios are tuned to balance acceleration with fuel economy, providing a comfortable driving experience.
Driving Characteristics
The E 350 BlueTEC Cabriolet delivers a distinctly different driving experience compared to its gasoline counterparts. The substantial 620 Nm (457 lb-ft) of torque, available from a low 1600-2400 rpm, provides effortless acceleration and strong pulling power. While not as outright quick as the E 550, the diesel offers a more relaxed and confident driving style, particularly during highway cruising and overtaking maneuvers. The 7G-TRONIC PLUS transmission contributes to smooth and seamless gear changes, enhancing the overall driving experience. The relatively high weight of the vehicle (1860 kg / 4100.6 lbs) is noticeable, but the torque compensates for this, providing brisk acceleration. Compared to manual transmission versions (not commonly offered in this configuration), the automatic prioritizes convenience and ease of use.
Equipment & Trim Levels
The E 350 BlueTEC Cabriolet came well-equipped as standard. Typical features included leather upholstery, automatic climate control, a premium sound system, and a power-operated soft top. The interior design mirrored the overall E-Class aesthetic, emphasizing luxury and comfort. Optional extras included features like the AIRMATIC suspension system for a more comfortable ride, advanced driver-assistance systems (such as lane keeping assist and blind spot monitoring), and upgraded infotainment systems with navigation. Interior trim options allowed for personalization, with choices in wood veneers and aluminum accents. The standard dashboard configuration featured analog gauges combined with a central display screen for infotainment and vehicle information.
Chassis & Braking
The E 350 BlueTEC Cabriolet utilized a sophisticated chassis design to provide a comfortable and controlled ride. The front suspension featured a coil spring, independent multi-link setup with a transverse stabilizer bar, while the rear employed an independent multi-link spring suspension, also with a stabilizer bar. This configuration minimized body roll and provided good handling characteristics. The braking system consisted of ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The steering system was a rack and pinion type with electric power steering, offering precise and responsive steering feel.
Market Reception & Comparison
The E 350 BlueTEC Cabriolet was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and fuel efficiency. Compared to the gasoline-powered E 350 Cabriolet, the BlueTEC offered superior fuel economy and torque, making it a more practical choice for long-distance driving. However, some critics noted that the diesel engine lacked the sporty character of the gasoline engines. Compared to the higher-performance E 550 Cabriolet, the E 350 BlueTEC offered a more balanced combination of performance and efficiency. Reliability reports suggest that the OM642 engine is generally durable, but regular maintenance is crucial to prevent issues with the diesel particulate filter and injection system.
Legacy
The Mercedes-Benz E 350 BlueTEC Cabriolet (A207) has established itself as a reliable and desirable used car. The OM642 engine is known for its longevity, provided it has been properly maintained. The 7G-TRONIC PLUS transmission is also generally reliable. However, potential buyers should be aware of the potential for issues with the diesel particulate filter (DPF) and the AdBlue system, particularly on vehicles that have primarily been used for short trips. Today, these cars offer a compelling value proposition, providing a luxurious and refined open-air driving experience at a relatively affordable price point. The combination of a powerful diesel engine, comfortable ride, and well-equipped interior continues to appeal to buyers seeking a sophisticated and practical convertible.
