Technical Specifications

INTRODUCTION

The GL 350 CDI BlueEFFICIENCY, introduced as part of the X164’s facelift in 2009 and continuing through 2012, was a key model in Mercedes-Benz’s large SUV range. Built on the 1HX0/A3 platform, it offered a compelling combination of space, luxury, and diesel efficiency. The facelift brought revised styling, improved interior materials, and updated technology, solidifying the GL-Class’s position as a competitor to vehicles like the BMW X5, Audi Q7, and Land Rover Discovery. The 350 CDI variant specifically targeted buyers seeking a powerful yet economical SUV for family use and long-distance travel.

Powertrain & Engine Architecture

At the heart of the GL 350 CDI BlueEFFICIENCY lies the OM 642.940 3.0-liter V6 diesel engine. This engine is a robust and well-regarded unit, known for its durability and strong torque output. It features a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine utilizes a variable geometry turbocharger (VGT) and an intercooler to enhance power and efficiency. The DOHC (Double Overhead Camshaft) valvetrain, with four valves per cylinder, further contributes to the engine’s performance. The 7G-TRONIC automatic transmission, a seven-speed unit, was standard. This transmission is known for its smooth shifting and ability to optimize engine speed for both performance and fuel economy. The transmission’s gear ratios are tuned to maximize the engine’s torque, providing strong acceleration even when fully loaded.

Driving Characteristics

The GL 350 CDI Automatic delivers a refined and capable driving experience. While not a sports SUV, the 265 horsepower and substantial 457 lb-ft of torque provide ample power for everyday driving and towing. Acceleration from 0-60 mph takes approximately 7.5 seconds, which is respectable for a vehicle of this size and weight. The 7G-TRONIC transmission contributes to smooth and seamless gear changes, minimizing disruptions during acceleration. Compared to the GL 550 with its larger gasoline engine, the 350 CDI prioritizes fuel efficiency and low-end torque over outright speed. The automatic transmission, while convenient, doesn’t offer the same level of driver engagement as a manual gearbox. However, it provides a comfortable and effortless driving experience, particularly on long journeys.

Equipment & Trim Levels

The GL 350 CDI BlueEFFICIENCY came well-equipped as standard. Typical features included leather upholstery, power-adjustable front seats with memory function, dual-zone automatic climate control, a premium audio system, and a navigation system. Safety features were also comprehensive, including ABS, ESP (Electronic Stability Program), multiple airbags, and parking sensors. Optional extras included a panoramic sunroof, rear-seat entertainment system, adaptive cruise control, and upgraded interior trim options. The interior design was characterized by Mercedes-Benz’s signature blend of luxury and functionality, with high-quality materials and a user-friendly layout.

Chassis & Braking

The GL-Class features a robust chassis designed to handle the vehicle’s weight and provide a comfortable ride. The front suspension utilizes a double wishbone setup, while the rear employs an independent multi-link suspension. This configuration provides a good balance between ride comfort and handling. The 4MATIC all-wheel-drive system distributes power between the front and rear axles as needed, enhancing traction in various conditions. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) are standard, further enhancing safety.

Market Reception & Comparison

The GL 350 CDI BlueEFFICIENCY was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, spacious interior, and strong towing capacity. Compared to the GL 450 and GL 550, the 350 CDI offered a more economical option without sacrificing too much in terms of performance or luxury. However, some critics noted that the diesel engine could be somewhat noisy compared to the gasoline alternatives. Fuel economy figures of around 26 mpg combined were considered excellent for a vehicle of this size. Reliability was generally good, although diesel particulate filter (DPF) maintenance was a consideration for owners.

Legacy

The Mercedes-Benz GL 350 CDI BlueEFFICIENCY has proven to be a durable and reliable SUV. On the used car market, these models continue to be sought after by buyers looking for a spacious, luxurious, and fuel-efficient vehicle. The OM 642 engine is known for its longevity, provided it has been properly maintained. Regular servicing, including DPF regeneration and oil changes, is crucial for ensuring the engine’s continued reliability. While newer SUVs offer more advanced technology and features, the GL 350 CDI remains a compelling option for those seeking a well-built and capable luxury SUV at a reasonable price.
