Powertrain & Engine Architecture
The E 220d All-Terrain is powered by the OM 654 M, a 2.0-liter inline-four cylinder diesel engine. This engine is a cornerstone of Mercedes-Benz’s modern diesel offerings, known for its efficiency and refinement. It features a high-pressure commonrail direct injection system, delivering fuel at up to 2,700 bar for optimized combustion. The engine also incorporates a variable geometry turbocharger and intercooler to enhance power and torque across the rev range. The mild-hybrid system utilizes a 48-volt electrical architecture and integrates a belt-driven starter-generator (BSG). This BSG provides a power boost during acceleration, allows for coasting with the engine switched off (gliding), and enables a smoother start/stop function. The 9G-TRONIC automatic transmission, with nine forward gears, is standard. This transmission is designed for smooth shifts and efficient operation, contributing to the overall fuel economy. The transmission’s gear ratios are tuned to provide a balance between acceleration and cruising efficiency.
Driving Characteristics
The E 220d All-Terrain, with its 197 horsepower and 440 Nm (324.5 lb-ft) of torque, offers respectable performance. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 8.1 seconds. While not a sports car, the engine provides sufficient power for comfortable highway cruising and overtaking. The 9G-TRONIC transmission contributes to a relaxed driving experience, with smooth gear changes and a wide range of ratios. Compared to higher-output E-Class variants, such as the E 300d, the E 220d offers a more fuel-efficient and less aggressive driving experience. The All-Terrain’s raised suspension and all-wheel drive system provide enhanced stability and traction on loose or slippery surfaces, making it suitable for light off-road use. The steering is precise and well-weighted, providing a confident feel on the road.
Equipment & Trim Levels
The E 220d All-Terrain typically comes well-equipped as standard. Key features include Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, digital instrument cluster, leather upholstery, heated front seats, and a panoramic sunroof. Standard safety features include adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras include advanced driver-assistance systems, premium sound systems, and various interior trim options. The All-Terrain trim level also adds unique exterior styling elements, such as rugged body cladding, chrome accents, and increased ground clearance.
Chassis & Braking
The S214 All-Terrain utilizes a sophisticated chassis design. The front suspension features independent multi-link setup with air suspension, while the rear also employs an independent multi-link configuration with air suspension. The air suspension system allows for adjustable ride height, providing increased ground clearance for off-road driving and improved comfort on the highway. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) are standard safety features.
Market Reception & Comparison
The E-Class All-Terrain, including the E 220d variant, has been well-received in European markets, where the demand for premium wagons with all-wheel drive is strong. Critics have praised its comfortable ride, spacious interior, and versatile capabilities. Compared to other trims in the E-Class lineup, the E 220d offers a more affordable entry point while still providing a luxurious and capable driving experience. Its fuel economy is generally better than that of the more powerful E 300d, making it an attractive option for drivers who prioritize efficiency.
Legacy
The OM 654 engine family, including the version used in the E 220d All-Terrain, has proven to be a reliable and durable powertrain. While long-term reliability data for the S214 generation is still emerging, the engine’s robust design and advanced technology suggest it will offer years of dependable service. On the used car market, the E 220d All-Terrain is expected to hold its value well, due to its desirable combination of luxury, practicality, and all-weather capability. The mild-hybrid system adds a layer of future-proofing, as emissions regulations continue to tighten.
