INTRODUCTION
The Mercedes-Benz ML 350 V6 4MATIC, part of the W164 M-Class series (facelifted in 2008), was designed to appeal to a broad range of luxury SUV buyers. Built on the 164 platform, it offered a blend of comfort, capability, and technology. The facelift brought revised styling, improved interior materials, and updated engine options, enhancing the M-Class’s competitiveness. This particular variant, with its 3.5-liter V6 engine and 7G-TRONIC transmission, was a popular choice for those prioritizing a smooth driving experience and reasonable fuel economy within the luxury SUV segment.
Powertrain & Engine Architecture
At the heart of the ML 350 was the M 272.967 3.5-liter naturally aspirated V6 engine. This engine featured a 60-degree V-angle and utilized a multi-port fuel injection system. The engine code ‘272’ signified the engine family, while ‘967’ denoted the specific displacement and configuration. The engine produced 272 horsepower at 6,000 rpm and 350 Nm (258 lb-ft) of torque between 2,400 and 5,000 rpm. It employed a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The 7G-TRONIC automatic transmission, a seven-speed unit, was a key component of this powertrain. It offered smooth and efficient gear changes, contributing to the ML 350’s refined driving experience. The transmission was known for its adaptability, offering both comfort and sport modes to suit different driving styles.
Driving Characteristics
The ML 350 4MATIC, with its 272 hp and 7-speed automatic, delivered a comfortable and capable driving experience. Acceleration from 0 to 60 mph took approximately 8 seconds, and it had a top speed of 139.81 mph. While not as sporty as the ML 500 or AMG variants, the ML 350 provided adequate power for everyday driving and highway cruising. The 7G-TRONIC transmission played a crucial role in optimizing power delivery, keeping the engine in its optimal torque band. Compared to the manual transmission options available on other M-Class models, the automatic prioritized smoothness and ease of use over outright performance. The 4MATIC all-wheel-drive system provided enhanced traction and stability in various weather conditions.
Equipment & Trim Levels
The ML 350 4MATIC came standard with a respectable array of features, including leather upholstery, dual-zone automatic climate control, power-adjustable front seats, and a premium audio system. Optional extras included a navigation system, rear-seat entertainment system, panoramic sunroof, and various driver-assistance features like parking sensors and adaptive cruise control. Interior trim options allowed buyers to personalize the vehicle to their preferences. The standard dashboard configuration featured wood trim accents and a multi-function steering wheel. The overall interior ambiance was one of understated luxury and refinement.
Chassis & Braking
The W164 M-Class featured a robust chassis with a double wishbone front suspension and an independent multi-link rear suspension. Both ends incorporated transverse stabilizers to reduce body roll during cornering. The ML 350 was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. The anti-lock braking system (ABS) was standard, enhancing braking performance and stability. The suspension tuning prioritized comfort and ride quality, making it well-suited for long-distance driving. The 4MATIC all-wheel-drive system distributed power between the front and rear axles as needed, optimizing traction and handling.
Market Reception & Comparison
The ML 350 4MATIC was generally well-received by automotive critics. It was praised for its comfortable ride, spacious interior, and refined powertrain. However, some reviewers noted that its fuel economy was not class-leading, and its handling was not as sharp as some of its European competitors. Compared to the ML 300, the ML 350 offered a significant performance upgrade. In contrast to the ML 500, it provided a more balanced combination of performance and fuel efficiency. The ML 350’s reliability was generally considered good, although some owners reported minor issues with electronic components.
Legacy
The Mercedes-Benz ML 350 V6 4MATIC (W164) has proven to be a relatively reliable and durable SUV in the used car market. The M 272 engine, while requiring regular maintenance, is generally considered robust. The 7G-TRONIC transmission is also known for its longevity when properly serviced. Today, these vehicles can be found with reasonable mileage and are often sought after by buyers looking for a well-equipped and comfortable luxury SUV at a more affordable price point. However, potential buyers should be aware of potential issues with the air suspension system (if equipped) and the electronic stability program.
