2020-2023 Mercedes-Benz GLE SUV (V167) GLE 350e (333 Hp) Plug-in Hybrid 4MATIC 9G-TRONIC

Technical Specifications

The Mercedes-Benz GLE 350e, a plug-in hybrid variant of the V167 GLE SUV, was produced from June 2020 through 2023. Positioned as a mid-range offering within the GLE lineup, it aimed to provide a balance between performance, efficiency, and environmental responsibility. The 350e combined a turbocharged four-cylinder gasoline engine with an electric motor, offering all-wheel drive capability through Mercedes-Benz’s 4MATIC system and utilizing a 9G-TRONIC automatic transmission. This model represented Mercedes-Benz’s increasing focus on electrification and catered to buyers seeking a premium SUV with reduced emissions and the flexibility of electric-only driving.

Powertrain & Engine Architecture

The GLE 350e’s powertrain centers around the M 274.920 2.0-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is coupled with a single turbocharger and intercooler, producing 211 horsepower and 350 Nm (258.15 lb.-ft.) of torque. The electric motor, positioned between the engine and the 9G-TRONIC automatic transmission, contributes an additional 163 horsepower and 440 Nm (324.53 lb.-ft.) of torque. The combined system output reaches 333 horsepower. The 9G-TRONIC transmission, a nine-speed automatic, is specifically calibrated to work seamlessly with the electric motor, optimizing efficiency and providing smooth gear changes. The lithium-ion battery pack, with a gross capacity of 31.2 kWh and a usable capacity of 27 kWh, is located under the trunk floor, impacting cargo space slightly. The battery supports AC charging for convenient home or public charging.

Driving Characteristics

The GLE 350e offers a distinct driving experience compared to its gasoline-only counterparts. In electric-only mode, the vehicle provides near-silent operation and instant torque, making it ideal for city driving. The all-electric range of 84-98 km (52.2 – 60.89 mi) allows for many daily commutes to be completed without using the gasoline engine. When the battery is depleted or additional power is needed, the gasoline engine seamlessly kicks in, providing a combined output that delivers brisk acceleration – 0 to 60 mph in approximately 6.6 seconds. The 9G-TRONIC transmission’s wide gear ratio spread helps to keep the engine in its optimal power band, while the electric motor fills in torque gaps for a responsive feel. Compared to the GLE 450, the 350e prioritizes efficiency over outright performance, but still offers a respectable level of power for everyday driving.

Equipment & Trim Levels

The GLE 350e typically came well-equipped, reflecting its position as a premium offering. Standard features included Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, leather upholstery, heated front seats, and a panoramic sunroof. Safety features such as automatic emergency braking, lane keeping assist, and blind spot monitoring were also standard. Optional extras included advanced driver-assistance systems like adaptive cruise control, upgraded audio systems, and various interior trim options. The interior design mirrored other GLE models, with a focus on luxury and modern aesthetics. The dashboard layout was clean and intuitive, with a blend of traditional analog controls and digital displays.

Chassis & Braking

The GLE 350e utilizes a double-wishbone front suspension and an independent multi-link rear suspension, providing a comfortable and controlled ride. Stabilizer bars are fitted to both axles to minimize body roll during cornering. The vehicle is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The 4MATIC all-wheel-drive system continuously distributes torque between the front and rear axles, enhancing traction and stability in various driving conditions. Due to the added weight of the battery pack, the suspension was tuned to provide a slightly firmer ride compared to the standard GLE models, but still prioritized comfort.

Market Reception & Comparison

The GLE 350e was generally well-received by automotive critics, who praised its fuel efficiency, smooth ride, and quiet operation in electric mode. However, some reviewers noted that the battery pack reduced cargo space compared to the non-hybrid GLE models. Compared to the GLE 300, the 350e offered significantly improved fuel economy and the ability to drive in electric-only mode, but came at a higher price point. Against the GLE 450, the 350e provided a more environmentally friendly option with comparable performance, but lacked the 450’s more powerful engine. Reliability reports have been generally positive, with few major issues reported regarding the hybrid powertrain.

Legacy

The Mercedes-Benz GLE 350e represents an important step in Mercedes-Benz’s transition towards electrification. The powertrain, while superseded by newer hybrid technologies, proved to be relatively reliable and offered a compelling combination of performance and efficiency. On the used car market, the GLE 350e remains a desirable option for buyers seeking a luxury SUV with plug-in hybrid capability. Its ability to operate in electric-only mode, combined with its comfortable ride and well-appointed interior, continues to appeal to environmentally conscious consumers. The model helped pave the way for Mercedes-Benz’s expanding range of electric and hybrid vehicles.
