The Mercedes-Benz GLE 450 (V167), produced from 2019 to 2023, represents a significant iteration of Mercedes-Benz’s mid-size luxury SUV. Positioned as a mainstream offering within the GLE lineup, it served as a bridge between the entry-level GLE 350 and the performance-oriented AMG variants. This model is characterized by its mild-hybrid (MHEV) powertrain, combining a 3.0-liter inline-six cylinder engine with a 48-volt EQ Boost system and a 9-speed G-TRONIC automatic transmission. The V167 generation marked a substantial leap forward in technology, comfort, and driving dynamics compared to its predecessor, the W166 GLE.

Powertrain & Engine Architecture
The heart of the GLE 450 is the M 256.930 3.0-liter inline-six cylinder engine. This engine utilizes direct injection and a twin-scroll turbocharger with intercooling to deliver a robust 367 horsepower and 369 lb-ft of torque. The key innovation is the 48-volt mild-hybrid system, featuring an integrated starter-generator (ISG). This ISG provides several benefits, including smoother start/stop operation, energy recuperation during braking, and a temporary power boost of up to 22 horsepower and 184 lb-ft of torque via the EQ Boost function. The 9-speed G-TRONIC automatic transmission is specifically tuned to work in conjunction with the mild-hybrid system, offering quick and seamless gear changes. The engine’s layout is front-mounted and longitudinal, contributing to a balanced weight distribution.
Driving Characteristics
The GLE 450 offers a refined and comfortable driving experience. The EQ Boost system effectively fills in torque gaps during acceleration, resulting in a responsive feel. While not as overtly sporty as the AMG variants, the GLE 450 provides ample power for everyday driving and highway passing. The 9-speed transmission is well-programmed, and generally imperceptible during normal driving. The 0-60 mph acceleration time of 5.5 seconds is respectable for a mid-size luxury SUV. Compared to the GLE 350, the 450 offers a noticeable increase in performance, while the higher-output AMG models deliver a significantly more aggressive driving experience. The suspension is tuned for comfort, but still provides adequate body control in corners.
Equipment & Trim Levels
The GLE 450 came standard with a comprehensive suite of features, including Mercedes-Benz User Experience (MBUX) infotainment system with a large touchscreen display, Apple CarPlay and Android Auto integration, leather upholstery, power-adjustable front seats with memory function, and a panoramic sunroof. Available options included multi-contour seats with massage function, a premium Burmester sound system, augmented reality navigation, and a variety of driver-assistance features such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Interior trim options ranged from wood veneers to aluminum accents, allowing for a degree of personalization.
Chassis & Braking
The V167 GLE utilizes a robust chassis with a multi-link independent suspension at all four corners. Air suspension was available as an option, providing adjustable ride height and improved comfort. The GLE 450 features ventilated disc brakes on all wheels, providing ample stopping power. Standard safety features include ABS, electronic stability control, and traction control. The 4MATIC all-wheel-drive system is full-time, distributing torque between the front and rear axles for optimal traction in various conditions.
Market Reception & Comparison
The GLE 450 was generally well-received by automotive critics, who praised its comfortable ride, refined interior, and advanced technology. The mild-hybrid system was lauded for its contribution to improved fuel economy and smoother operation. Compared to competitors such as the BMW X5 and Audi Q7, the GLE 450 offered a compelling combination of luxury, performance, and technology. Fuel economy figures, while not class-leading, were respectable for a vehicle of its size and weight. Reliability reports have been generally positive, although some owners have reported minor issues with the infotainment system.
Legacy
The Mercedes-Benz GLE 450 (V167) represents a pivotal model in the evolution of the GLE lineup. Its introduction of the MHEV powertrain demonstrated Mercedes-Benz’s commitment to improving fuel efficiency and reducing emissions. The V167 generation GLE established a new benchmark for luxury and technology in the mid-size SUV segment. On the used car market, the GLE 450 remains a desirable option, offering a blend of comfort, performance, and features at a competitive price point. The M 256 engine, in particular, has proven to be a durable and reliable powerplant, contributing to the long-term value of these vehicles.
