Powertrain & Engine Architecture
The heart of the E 350d 9G-TRONIC is the OM 642.855 3.0-liter V6 turbodiesel engine. This engine is a sophisticated design featuring a common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The engine utilizes a variable geometry turbocharger (VGT) and an intercooler to maximize power and efficiency. The V6 configuration provides inherent smoothness and balance, contributing to the refined driving experience. The engine produces 258 horsepower at 3400 rpm and a substantial 620 Nm (457 lb-ft) of torque between 1600 and 2400 rpm. This broad torque curve is a hallmark of modern diesel engines, providing strong acceleration in various driving situations. The 9G-TRONIC nine-speed automatic transmission is a key component, offering close gear ratios for optimal performance and fuel economy. It features a torque converter lockup clutch that engages in most gears, minimizing slippage and improving efficiency.
Driving Characteristics
The E 350d 9G-TRONIC delivers a refined and effortless driving experience. The abundant torque allows for brisk acceleration, with 0-60 mph times around 5.6 seconds. The nine-speed transmission keeps the engine operating in its optimal power band, contributing to both performance and fuel efficiency. Compared to the E 200d or E 220d models, the E 350d offers significantly more power and acceleration. While not as sporty as the E 43 AMG or other performance-oriented E-Class variants, the E 350d provides ample power for comfortable highway cruising and confident overtaking. The automatic transmission shifts smoothly and responsively, although some drivers may prefer the more direct control of a manual gearbox. The long gear ratios contribute to excellent fuel economy, especially on the highway.
Equipment & Trim Levels
The E 350d 9G-TRONIC typically came well-equipped as a mid-range to upper-mid-range trim. Standard features often included leather upholstery, automatic climate control, a high-resolution infotainment system with navigation, and a suite of driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras included a panoramic sunroof, premium sound system, massaging seats, and advanced parking assist features. Interior trim options varied, with choices in wood veneers, aluminum accents, and different leather colors. The overall interior design emphasized luxury and sophistication, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The W213 E-Class features a sophisticated chassis design with an independent multi-link suspension at both the front and rear. This suspension setup provides a comfortable ride while maintaining good handling characteristics. The E 350d typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and electronic stability control were standard features. The steering system is a rack-and-pinion setup with electric power assistance, offering precise and responsive steering feel. The suspension tuning was generally geared towards comfort, but the E 350d offered a good balance between ride quality and handling.
Market Reception & Comparison
The E 350d 9G-TRONIC was generally well-received by automotive critics. It was praised for its refined engine, smooth transmission, comfortable ride, and luxurious interior. Fuel economy was also a strong point, with the diesel engine offering significantly better mileage than comparable gasoline engines. Compared to other trims in the E-Class lineup, the E 350d offered a compelling combination of performance and efficiency. While the E 200d and E 220d were more affordable, they lacked the power and refinement of the E 350d. The E 43 AMG offered more performance, but at a significantly higher price point.
Legacy
The OM 642 engine family, including the OM 642.855 found in the E 350d, has a reputation for durability and reliability. With proper maintenance, these engines can accumulate high mileage without major issues. The 9G-TRONIC transmission is also generally considered to be a reliable unit. In the used car market, the E 350d 9G-TRONIC remains a desirable option for buyers seeking a comfortable, efficient, and well-equipped executive sedan. However, potential buyers should be aware of the potential for diesel emissions system issues, particularly with older models. Regular servicing and adherence to manufacturer-recommended maintenance schedules are crucial for ensuring the long-term reliability of this vehicle.
