The Mercedes-Benz G 350 CDI Long, produced from 2009 to 2010, represents a specific iteration of the iconic G-Class (W463) following the 2008 facelift. This variant was positioned as a mid-range offering within the G-Class lineup, bridging the gap between the base G 300 CDI and the higher-performance G 55 AMG. It combined the rugged capability expected of the G-Class with a more fuel-efficient diesel engine and the convenience of a seven-speed automatic transmission. The “Long” designation indicates an extended wheelbase, providing increased rear passenger space, making it particularly popular in markets where chauffeur-driven luxury was desired. This model was primarily sold in Europe and other international markets, with limited availability in the United States.

INTRODUCTION
The G 350 CDI Long, introduced in 2009 as part of the W463 facelift, continued the G-Class’s legacy as a supremely capable and luxurious off-road vehicle. The W463 generation, produced from 1990 to 2018, saw the G-Class evolve from a military-focused utility vehicle to a desirable luxury item. The facelift brought updated interior appointments, improved safety features, and refinements to the engine range. The extended wheelbase “Long” variant, offered primarily in Europe and Asia, catered to customers seeking increased rear legroom and a more comfortable passenger experience. This model year saw a shift towards more efficient diesel engines, aligning with tightening emissions regulations.
Powertrain & Engine Architecture
At the heart of the G 350 CDI Long lies the OM 642.970 3.0-liter V6 turbodiesel engine. This engine, a mainstay in many Mercedes-Benz vehicles of the era, is characterized by its robust construction and relatively smooth operation for a diesel. It utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The engine produces 224 horsepower at 3800 rpm and a substantial 540 Nm (398 lb-ft) of torque between 1600 and 2400 rpm. A variable geometry turbocharger and intercooler further enhance performance and efficiency. The engine is longitudinally mounted in the chassis. Paired with the engine is the 7G-TRONIC seven-speed automatic transmission, known for its smooth shifts and wide gear ratios. This transmission allows for both relaxed cruising and responsive acceleration. The 7G-TRONIC features a torque converter lock-up clutch to improve fuel economy at highway speeds.
Driving Characteristics
The G 350 CDI Long, despite its size and weight, offers surprisingly capable performance. The high torque output of the diesel engine provides strong acceleration, particularly in the lower and mid-range. The 7G-TRONIC transmission contributes to a refined driving experience, with seamless gear changes. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 9.1 seconds. While not a sports car, the G 350 CDI Long possesses enough power for confident overtaking maneuvers. The automatic transmission’s gear ratios are tuned for both on-road comfort and off-road capability, providing ample low-end torque for navigating challenging terrain. Compared to the more powerful G 55 AMG, the G 350 CDI Long prioritizes fuel efficiency and relaxed cruising over outright performance. Compared to the G 300 CDI, the G 350 CDI offers a noticeable power increase and a more refined driving experience thanks to the V6 configuration and the 7G-TRONIC transmission.
Equipment & Trim Levels
The G 350 CDI Long came standard with a comprehensive list of features, reflecting its luxury positioning. Interior appointments typically included leather upholstery, wood trim, and automatic climate control. Standard safety equipment included ABS, traction control, and multiple airbags. The “Long” variant specifically offered increased rear legroom compared to the standard wheelbase G-Class. Optional extras included a sunroof, upgraded audio system, navigation system, and various exterior customization options. The G-Class was known for its extensive personalization options, allowing customers to tailor the vehicle to their specific preferences.
Chassis & Braking
The G 350 CDI Long retains the traditional G-Class body-on-frame construction, providing exceptional durability and off-road capability. The chassis is underpinned by a rigid axle suspension system with coil springs, offering substantial wheel articulation for tackling uneven terrain. The front and rear axles are equipped with ventilated disc brakes, providing ample stopping power. The vehicle’s robust construction and all-wheel-drive system contribute to its exceptional off-road prowess. The G 350 CDI Long features a three-differential system (front, center, and rear) that can be locked for maximum traction in extreme conditions.
Market Reception & Comparison
The G 350 CDI Long was generally well-received by automotive critics, who praised its blend of luxury, capability, and relatively improved fuel economy compared to the gasoline-powered G-Class models. The diesel engine’s torque output was particularly appreciated for its ability to handle challenging terrain and tow heavy loads. However, some critics noted the G-Class’s relatively high price and somewhat dated interior design. Compared to other luxury SUVs of the time, the G-Class stood out for its unique styling and uncompromising off-road capability. Fuel economy, while improved over the gasoline variants, remained relatively high at 11 l/100 km (21.4 US mpg). Reliability was generally good, although the complex four-wheel-drive system and electronic features could require specialized maintenance.
Legacy
The G 350 CDI Long, while a relatively short-lived variant, remains a desirable vehicle in the used car market. The OM 642 diesel engine is known for its durability, although regular maintenance is crucial. The 7G-TRONIC transmission is also generally reliable, but may require fluid changes and occasional servicing. The G-Class’s iconic status and enduring appeal ensure continued demand for well-maintained examples. The G 350 CDI Long represents a unique combination of luxury, capability, and diesel efficiency within the G-Class lineage, making it a sought-after vehicle for enthusiasts and collectors alike.
