Powertrain & Engine Architecture
The GLE 350d 4MATIC is powered by the OM 656.929, a 2.9-liter inline-six cylinder diesel engine. This engine is a significant departure from the older V6 diesels used by Mercedes-Benz, featuring a modular design and advanced technologies. The OM 656 utilizes a steel piston, a variable-geometry turbocharger, and a two-stage intercooler to deliver both power and efficiency. The engine employs a common-rail direct fuel injection system operating at extremely high pressures (2700 bar) for optimized combustion. The valvetrain features four valves per cylinder and utilizes a camshaft positioning system for improved responsiveness. Paired with the engine is the 9G-TRONIC nine-speed automatic transmission. This transmission is known for its smooth shifts and wide gear ratio spread, contributing to both fuel economy and performance. The 9G-TRONIC allows the engine to operate within its optimal efficiency range more frequently.
Driving Characteristics
The 272 horsepower and 600 Nm (442 lb-ft) of torque produced by the OM 656 engine provide the GLE 350d with strong acceleration and effortless cruising ability. The 0-60 mph sprint takes approximately 6.3 seconds, making it adequately quick for most driving situations. The 9G-TRONIC transmission contributes to a relaxed driving experience, with smooth and almost imperceptible gear changes. Compared to the higher-output GLE 450, the 350d offers less outright performance, but its abundant low-end torque makes it feel surprisingly responsive in everyday driving. The automatic transmission is tuned for comfort and efficiency, prioritizing smooth shifts over aggressive downshifts. While manual shift modes are available, they don’t offer the same level of engagement as a dedicated performance-oriented transmission.
Equipment & Trim Levels
The GLE 350d 4MATIC typically came standard with a generous array of features, including Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, leather upholstery, heated front seats, automatic climate control, and a suite of advanced driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras included features like a panoramic sunroof, premium Burmester audio system, ventilated front seats, and a head-up display. Interior trim options ranged from aluminum to wood veneers, allowing buyers to personalize the cabin to their preferences. The exterior styling featured chrome accents and distinctive LED lighting.
Chassis & Braking
The GLE 350d 4MATIC utilizes a fully independent suspension system, with air suspension available as an option. The standard suspension provides a comfortable ride, while the air suspension offers adjustable ride height and damping settings for enhanced comfort and off-road capability. The vehicle is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The 4MATIC all-wheel-drive system distributes torque between the front and rear axles as needed, enhancing traction and stability in various driving conditions. The steering is electrically assisted, providing a precise and responsive feel.
Market Reception & Comparison
The GLE 350d 4MATIC was generally well-received by automotive critics, who praised its comfortable ride, refined interior, and efficient diesel engine. It was often seen as a strong alternative to petrol-powered SUVs, offering comparable performance with significantly better fuel economy. Compared to the GLE 450, the 350d offered a more affordable entry point into the GLE Coupe range, albeit with slightly less power. The 350d’s fuel economy figures were notably better than those of the GLE 450, making it an attractive option for drivers who prioritize efficiency. However, some critics noted that the diesel engine could be slightly noisy compared to the smoother petrol engines.
Legacy
The OM 656 engine family has proven to be remarkably reliable, and the GLE 350d 4MATIC is generally considered a well-built and durable vehicle. On the used car market, these models hold their value reasonably well, reflecting their reputation for quality and refinement. Regular maintenance, including oil changes and filter replacements, is crucial for ensuring the long-term reliability of the diesel engine and the 9G-TRONIC transmission. The GLE 350d 4MATIC represents a compelling blend of luxury, performance, and efficiency, making it a desirable choice for buyers seeking a versatile and capable SUV.
