INTRODUCTION
The Mercedes-Benz E 350 BlueTEC Cabriolet (A207, facelift 2013) was introduced as a sophisticated open-top offering within the E-Class range. Positioned as a premium variant, it catered to buyers seeking a luxurious and efficient grand tourer. The A207 facelift, launched in 2013, brought significant updates to the E-Class, including revised styling, enhanced safety features, and a new generation of engines. The E 350 BlueTEC, with its powerful yet economical diesel engine and smooth 9G-TRONIC automatic transmission, aimed to deliver a refined driving experience. It competed with other luxury cabriolets, such as the BMW 6 Series Convertible and Audi A5 Cabriolet.
Powertrain & Engine Architecture
At the heart of the E 350 BlueTEC Cabriolet lies the OM 642.838 3.0-liter V6 diesel engine. This engine is a hallmark of Mercedes-Benz diesel technology, known for its robust construction and refined operation. 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 efficiency. The valvetrain employs Double Overhead Camshafts (DOHC) with four valves per cylinder, contributing to its strong performance across the rev range. Paired with this engine is the 9G-TRONIC nine-speed automatic transmission. This transmission is designed for smooth and efficient gear changes, offering a wide range of ratios to optimize fuel economy and performance. The 9G-TRONIC also features a torque converter lockup clutch that engages in most driving situations, further enhancing efficiency. The engine also incorporates a Start & Stop system and a particulate filter to reduce emissions, meeting stringent Euro 6 standards.
Driving Characteristics
The E 350 BlueTEC Cabriolet delivers a refined and comfortable driving experience. The 620 Nm (457.29 lb.-ft.) of torque available from 1600-2400 rpm provides strong acceleration in all gears, making overtaking effortless. The 9G-TRONIC transmission contributes to smooth and seamless gear changes, enhancing the overall driving experience. While not as overtly sporty as some of its gasoline-powered counterparts, the E 350 BlueTEC offers ample power for spirited driving. The 0-60 mph time of around 6.2 seconds is respectable for a luxury cabriolet. The long wheelbase and well-tuned suspension provide a comfortable ride, even on uneven surfaces. The rear-wheel drive configuration contributes to balanced handling, although it doesn’t offer the all-weather capability of an all-wheel drive system. The steering is precise and well-weighted, providing good feedback to the driver.
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 featured high-quality materials and a sophisticated design. Optional extras included features such as a navigation system, heated and ventilated seats, a panoramic sunroof, and advanced driver-assistance systems like lane keeping assist and adaptive cruise control. Trim levels varied depending on the market, but generally offered options for upgraded interior finishes, exterior styling enhancements, and additional technology features. The standard dashboard configuration featured analog gauges with a central display screen for infotainment and vehicle information.
Chassis & Braking
The E 350 BlueTEC Cabriolet utilizes a coil spring, independent multi-link suspension system at both the front and rear, incorporating a transverse stabilizer bar at the front. This setup provides a good balance between ride comfort and handling. The Cabriolet’s chassis was reinforced to compensate for the lack of a fixed roof, ensuring structural rigidity. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The electric power steering system offers 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 driving experience, fuel efficiency, and luxurious interior. Compared to the gasoline-powered E-Class Cabriolet models, the BlueTEC offered significantly better fuel economy and a broader torque curve. However, some critics noted that the diesel engine lacked the responsiveness and sound of the gasoline engines. Compared to competitors like the BMW 6 Series Convertible, the E 350 BlueTEC offered a more comfortable ride and a more luxurious interior, but the BMW was often considered more engaging to drive. The E 350 BlueTEC’s fuel economy figures of 5.3-5.5 l/100 km (44.4 – 42.8 US mpg) were competitive within its segment.
Legacy
The OM 642 engine family, including the OM 642.838 found in the E 350 BlueTEC, is known for its durability and reliability. With proper maintenance, these engines can accumulate high mileage without major issues. The 9G-TRONIC transmission has also proven to be a reliable unit. In the used car market, the E 350 BlueTEC Cabriolet represents a good value proposition for buyers seeking a luxurious and efficient open-top experience. However, potential buyers should be aware of the potential maintenance costs associated with diesel engines, such as diesel particulate filter (DPF) maintenance and AdBlue refills. Overall, the E 350 BlueTEC Cabriolet remains a desirable and well-regarded vehicle, offering a compelling combination of luxury, performance, and efficiency.
