Powertrain & Engine Architecture
At the heart of the E 450 All-Terrain lies the M 256 3.0-liter inline-six cylinder engine. This engine is a marvel of modern engineering, featuring direct injection, a twin-scroll turbocharger, and an intercooler. The M 256 engine is notable for its implementation of a 48-volt mild hybrid system (EQ Boost). This system utilizes a 22 horsepower electric motor integrated into the powertrain, providing assistance during acceleration and enabling features like coasting with engine-off to improve fuel efficiency. The engine produces 367 horsepower and 500 Nm (368.78 lb-ft) of torque, available from a low 1600 rpm, providing strong and responsive performance. The engine is paired with Mercedes-Benz’s 9G-TRONIC nine-speed automatic transmission, known for its smooth shifts and wide gear ratios. This transmission is specifically tuned for the All-Terrain model to optimize both on-road comfort and off-road capability.
Driving Characteristics
The E 450 All-Terrain delivers a refined and capable driving experience. The combination of the powerful inline-six engine and the 9G-TRONIC transmission results in brisk acceleration – 0 to 60 mph in approximately 5.1 seconds. The EQ Boost system provides an immediate boost in torque, enhancing responsiveness. While not a dedicated off-roader, the All-Terrain’s increased ground clearance and 4MATIC all-wheel drive system allow it to confidently tackle moderate terrain and adverse weather conditions. Compared to the E 450 sedan, the All-Terrain offers a slightly softer suspension setup to absorb bumps and provide a more comfortable ride. Compared to lower-powered E-Class All-Terrain variants (like the E 220d), the E 450 provides significantly more power and a more engaging driving experience, albeit at the cost of some fuel economy.
Equipment & Trim Levels
The E 450 All-Terrain came standard with a high level of equipment, reflecting its position as the flagship model. Standard features typically included leather upholstery, heated and ventilated front seats, a panoramic sunroof, a premium Burmester sound system, and a comprehensive suite of driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. The infotainment system featured a large touchscreen display with Mercedes-Benz’s MBUX interface, offering voice control and augmented reality navigation. Optional extras included air suspension, massaging seats, and a head-up display. Interior trim options ranged from wood veneers to aluminum accents, allowing buyers to personalize the cabin to their preferences.
Chassis & Braking
The E 450 All-Terrain utilizes a steel suspension with adaptive damping as standard. Air suspension was available as an option, providing even greater ride comfort and the ability to raise the vehicle’s ride height for increased ground clearance. The All-Terrain features a robust braking system with ventilated discs on all four wheels. The 4MATIC all-wheel drive system is full-time, distributing torque between the front and rear axles as needed to maximize traction. The system is capable of sending up to 50% of the torque to the rear wheels, enhancing handling and stability.
Market Reception & Comparison
The E-Class All-Terrain E 450 was generally well-received by automotive critics. It was praised for its luxurious interior, powerful engine, and all-weather capability. Critics noted that it offered a compelling alternative to traditional SUVs, providing a more engaging driving experience and a more practical cargo area. Compared to other premium wagons, such as the Audi A6 allroad and the Volvo V90 Cross Country, the E 450 All-Terrain was often cited as offering a more refined and technologically advanced experience. Fuel economy, while respectable, was not a standout feature, with combined figures around 27.7 mpg. Reliability reports have been generally positive, with few major issues reported.
Legacy
The Mercedes-Benz E-Class All-Terrain E 450 (S213 facelift) represents a significant step forward in the evolution of the luxury wagon. Its combination of performance, comfort, and capability has made it a popular choice among buyers seeking a versatile and refined vehicle. On the used car market, these models hold their value well, reflecting their build quality and desirable features. The M 256 engine, with its mild-hybrid technology, is considered a reliable and efficient powerplant, and the 9G-TRONIC transmission has proven to be durable and smooth-shifting. As a result, the E 450 All-Terrain is likely to remain a sought-after vehicle for years to come.
