INTRODUCTION
The Mercedes-Benz GLE 400d 4MATIC G-TRONIC, launched in 2019 as part of the V167 GLE generation, filled a crucial niche in the luxury SUV market. Built on the MHA (Modular High Architecture) platform, also underpinning the W213 E-Class, the V167 GLE represented a significant step forward in terms of technology, comfort, and driving dynamics. The 400d variant, powered by a potent inline-six diesel engine, was specifically designed to appeal to customers prioritizing fuel efficiency and strong torque delivery without sacrificing the luxury and refinement expected from the Mercedes-Benz brand. It served as a compelling alternative to gasoline-powered GLE models and other premium SUV competitors.
Powertrain & Engine Architecture
At the heart of the GLE 400d lies the OM 656 2.9-liter inline-six diesel engine. This engine, a cornerstone of Mercedes-Benz’s modern diesel lineup, is notable for its advanced technology and robust construction. It features a sophisticated common-rail direct injection system operating at pressures up to 2,700 bar, ensuring precise fuel delivery and optimized combustion. The engine also incorporates a variable geometry turbocharger with water cooling and a steel piston design for enhanced durability. The ‘d’ designation signifies a diesel engine, and the 400 indicates a power output roughly corresponding to 4.0 liters of displacement in older engine classifications. The 9G-TRONIC automatic transmission, a nine-speed unit, is standard. This transmission is known for its smooth shifts, wide gear ratios, and contribution to fuel efficiency. The 9G-TRONIC features a torque converter lockup clutch that engages across multiple gears, minimizing slippage and improving responsiveness.
Driving Characteristics
The GLE 400d delivers a remarkably refined and capable driving experience. The engine’s substantial 700 Nm (516 lb-ft) of torque, available from a low 1200 rpm, provides effortless acceleration and strong pulling power. The 9G-TRONIC transmission complements the engine well, offering seamless gear changes and keeping the engine within its optimal power band. While not as overtly sporty as some of its gasoline-powered counterparts, the GLE 400d offers a confident and composed ride, particularly on the highway. The 4MATIC all-wheel-drive system provides excellent traction in various conditions, enhancing stability and control. The gear ratios are tuned for a balance between fuel economy and performance, with taller gears for relaxed cruising and shorter gears for quicker acceleration when needed.
Equipment & Trim Levels
The GLE 400d 4MATIC G-TRONIC typically came well-equipped as standard. Core features included Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, leather upholstery, power-adjustable front seats with memory function, dual-zone automatic climate control, and a comprehensive suite of safety features like adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras included air suspension (AIRMATIC), multi-contour seats with massage function, a panoramic sunroof, premium Burmester audio system, and various interior trim options. The interior design emphasized luxury and modern aesthetics, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The V167 GLE features a sophisticated chassis design aimed at balancing comfort and handling. The suspension utilizes a multi-link setup at both the front and rear, providing a smooth and controlled ride. The GLE 400d typically came equipped with ventilated disc brakes on all four wheels, offering ample stopping power. The braking system incorporates ABS (Anti-lock Braking System), Electronic Stability Program (ESP), and Brake Assist. Depending on the options selected, the GLE 400d could also be equipped with AIRMATIC air suspension, which allows for adjustable ride height and damping settings, further enhancing comfort and off-road capability. Stabilizer bars are fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The GLE 400d was generally well-received by automotive critics. It was praised for its powerful and efficient engine, comfortable ride, luxurious interior, and advanced technology. Compared to the GLE 350d (a lower-powered diesel variant), the 400d offered a noticeable performance upgrade. Against gasoline-powered GLE models like the GLE 450, the 400d provided superior fuel economy and torque, making it a more practical choice for long-distance driving and towing. However, some critics noted that the diesel engine could be slightly noisier than the gasoline alternatives. Reliability reports have been generally positive, with the OM 656 engine proving to be a robust and dependable unit.
Legacy
The Mercedes-Benz GLE 400d 4MATIC G-TRONIC has established itself as a desirable used car option. The OM 656 engine’s reputation for reliability and longevity contributes to its continued appeal. The combination of luxury, performance, and fuel efficiency makes it a compelling choice for buyers seeking a premium SUV. As with any diesel vehicle, proper maintenance, including regular oil changes and diesel particulate filter (DPF) servicing, is crucial for ensuring long-term reliability. The V167 GLE, and particularly the 400d variant, represents a high point in Mercedes-Benz’s SUV offerings, blending modern technology with traditional luxury and refinement.
