INTRODUCTION
The GLE 300d 4MATIC G-TRONIC, launched in 2019, is a diesel-powered variant of the V167 generation Mercedes-Benz GLE. This generation marked a significant step forward in terms of technology, comfort, and driving dynamics for the GLE. The 300d specifically targeted buyers seeking a balance between fuel economy and performance in a luxury SUV package. It utilizes a four-cylinder diesel engine paired with a sophisticated nine-speed automatic transmission and Mercedes’ 4MATIC all-wheel-drive system. The V167 GLE represented a move towards greater digitalization and connectivity, incorporating the Mercedes-Benz User Experience (MBUX) infotainment system.
Powertrain & Engine Architecture
At the heart of the GLE 300d lies the OM 654.920, a 2.0-liter inline-four cylinder diesel engine. This engine is a product of Mercedes-Benz’s modular engine family, known for its efficiency and refinement. It features a high-pressure common rail direct injection system, delivering fuel directly into the combustion chamber at pressures up to 2,700 bar. The engine also incorporates a variable geometry turbocharger with an intercooler, optimizing boost pressure across the engine’s operating range. The engine produces 245 horsepower at 4200 rpm and 500 Nm (368.78 lb.-ft.) of torque between 1600 and 2400 rpm. The engine is paired with the 9G-TRONIC nine-speed automatic transmission, known for its smooth shifts and wide gear ratio spread. This transmission is designed to optimize fuel efficiency and provide responsive acceleration. The 4MATIC all-wheel-drive system operates with a torque split favoring the rear wheels, enhancing driving dynamics.
Driving Characteristics
The GLE 300d 4MATIC G-TRONIC delivers a comfortable and refined driving experience. While not a performance-oriented variant, the engine provides ample torque for everyday driving and overtaking maneuvers. The nine-speed transmission contributes to relaxed cruising at highway speeds, with well-chosen gear ratios keeping the engine within its optimal power band. Acceleration from 0 to 60 mph takes approximately 6.8 seconds. Compared to the higher-output GLE 450 gasoline variant, the 300d offers less outright acceleration but significantly better fuel economy. The 4MATIC system provides confident traction in various weather conditions, enhancing stability and control. The suspension, tuned for comfort, effectively absorbs road imperfections, providing a smooth ride.
Equipment & Trim Levels
The GLE 300d 4MATIC G-TRONIC came standard with a comprehensive array of features, reflecting its positioning as a luxury SUV. Standard equipment typically included leather upholstery, power-adjustable front seats with memory function, dual-zone automatic climate control, and the MBUX infotainment system with a large touchscreen display. The MBUX system offered navigation, smartphone integration (Apple CarPlay and Android Auto), and voice control. Optional extras included a panoramic sunroof, premium sound system, advanced driver-assistance systems (such as adaptive cruise control, lane keeping assist, and blind-spot monitoring), and upgraded interior trim options. The GLE 300d could also be equipped with air suspension, further enhancing ride comfort and providing adjustable ride height.
Chassis & Braking
The V167 GLE features a robust chassis designed to provide a balance of comfort and handling. The suspension utilizes a four-link front axle and a multi-link rear axle. The GLE 300d typically came equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) were standard features. The steering system is a rack-and-pinion setup with electric power assistance, offering precise and responsive steering feel. The standard wheel and tire size for the GLE 300d was typically 20-inch, with tire dimensions of 275/50 R20.
Market Reception & Comparison
The GLE 300d 4MATIC G-TRONIC was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. Critics noted that while the engine wasn’t particularly powerful, it provided sufficient performance for most drivers. Compared to the gasoline-powered GLE 450, the 300d offered significantly better fuel economy, making it an attractive option for those prioritizing efficiency. However, the GLE 450 provided quicker acceleration and a more engaging driving experience. The 300d also compared favorably to competitors such as the Audi Q7 and BMW X5 in terms of fuel economy and overall refinement.
Legacy
The OM 654 engine family, used in the GLE 300d, has proven to be a reliable and durable powertrain. The nine-speed 9G-TRONIC transmission has also demonstrated good long-term reliability. On the used car market, the GLE 300d 4MATIC G-TRONIC represents a compelling value proposition, offering a luxurious and well-equipped SUV at a more affordable price point than newer models. The combination of fuel efficiency, comfort, and technology makes it a popular choice among buyers seeking a practical and refined mid-size SUV. Regular maintenance, including oil changes and adherence to Mercedes-Benz’s recommended service intervals, is crucial for ensuring the long-term reliability of this powertrain.
