Powertrain & Engine Architecture
The heart of the E 350d All-Terrain is the OM642.855 3.0-liter V6 turbodiesel engine. This engine, a mainstay of Mercedes-Benz’s diesel lineup for many years, is known for its robust construction and strong torque output. It utilizes a common-rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The engine also features a variable geometry turbocharger (VGT) and an intercooler to enhance performance and efficiency. The V6 configuration provides inherent smoothness compared to inline engines, and the 24-valve (four valves per cylinder) design contributes to its breathing efficiency. Paired with this engine is the 9G-TRONIC nine-speed automatic transmission. This transmission is designed for smooth shifts and optimized fuel economy, with closely spaced gear ratios to keep the engine operating in its peak power band. The 9G-TRONIC also features a torque converter lockup clutch that engages in most gears, improving efficiency.
Driving Characteristics
The E 350d All-Terrain delivers a refined and capable driving experience. The 620 Nm (457 lb-ft) of torque, available from a low 1600 rpm, provides effortless acceleration and strong pulling power, making it well-suited for towing or carrying heavy loads. The 9G-TRONIC transmission contributes to smooth and almost imperceptible gear changes. While not a sports car, the E 350d offers brisk performance, achieving 0-60 mph in around 5.9 seconds. Compared to the 1.6-liter four-cylinder diesel variants, the V6 provides a significantly more relaxed and refined driving experience, particularly at highway speeds. The All-Terrain’s raised suspension and 4MATIC all-wheel-drive system provide increased confidence on slippery surfaces and allow for light off-road excursions, though it’s not intended for serious off-roading.
Equipment & Trim Levels
The E 350d All-Terrain typically came well-equipped as standard. Features included leather upholstery, wood trim, 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. The All-Terrain also featured unique exterior styling cues, including rugged body cladding, flared wheel arches, and a chrome front skid plate. Optional extras included air suspension (AIRMATIC), a panoramic sunroof, premium sound system, and various interior customization options. Trim levels were often differentiated by wheel designs, interior color schemes, and the availability of certain optional packages.
Chassis & Braking
The E 350d All-Terrain utilizes a sophisticated chassis design. It features an independent multi-link suspension at both the front and rear, providing a comfortable ride and precise handling. The All-Terrain’s suspension is slightly raised compared to the standard E-Class wagon, providing increased ground clearance. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The electronic stability program (ESP) and anti-lock braking system (ABS) are standard features, enhancing safety and control. Steering is rack-and-pinion with electric power assistance, offering a responsive and precise feel.
Market Reception & Comparison
The E 350d All-Terrain was generally well-received by automotive critics. It was praised for its comfortable ride, strong performance, and practical versatility. Compared to the four-cylinder diesel variants, the V6 offered a more refined and enjoyable driving experience, albeit at a higher price point. Fuel economy was competitive for its class, averaging around 35 mpg in combined driving. Reliability has generally been good, although, like any complex vehicle, it’s susceptible to age-related issues. Compared to traditional SUVs, the All-Terrain offered a more car-like driving experience and superior fuel economy.
Legacy
The OM642 engine family, including the OM642.855 found in the E 350d All-Terrain, has a reputation for durability and longevity when properly maintained. These engines are known to be capable of high mileage with regular servicing. On the used car market, the E 350d All-Terrain holds its value relatively well, particularly well-maintained examples with low mileage. The combination of performance, practicality, and luxury continues to appeal to buyers seeking a versatile and capable vehicle. The All-Terrain concept itself has proven successful for Mercedes-Benz, paving the way for similar models in other segments.
