The Mercedes-Benz G-Class Long (W461), specifically the G 280 CDI Edition.PUR V6 4MATIC Automatic, represents a unique iteration of the iconic off-road vehicle. Produced for a limited time in 2009, this variant occupied a specific niche within the W461 facelift range, offering a blend of diesel efficiency, respectable power, and the G-Class’s legendary off-road capability. The W461 series, produced from 1990 to 2018, was primarily aimed at professional and military use, but also gained a following among civilian enthusiasts seeking a robust and capable vehicle. The 2009 facelift brought updated styling and mechanical refinements, and the G 280 CDI Edition.PUR was positioned as a more refined option within the long-wheelbase body style.

Powertrain & Engine Architecture
The heart of the G 280 CDI Edition.PUR is the OM 642.975, a 3.0-liter V6 diesel engine. This engine is a robust and well-regarded unit, known for its durability and torque output. It utilizes a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. A turbocharger with an intercooler further enhances performance, boosting power and efficiency. The engine produces 184 horsepower at 3800 rpm and a substantial 400 Nm (295 lb-ft) of torque between 1600 and 2600 rpm. This torque band is particularly well-suited to off-road driving, providing ample low-end grunt for tackling challenging terrain. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its smooth operation and efficient breathing. The 5-speed automatic transmission, while not the most modern unit by today’s standards, is known for its reliability and provides adequate shifting performance for the vehicle’s intended use.
Driving Characteristics
The G 280 CDI Automatic offers a driving experience that prioritizes capability and comfort over outright speed. The 184 hp engine, coupled with the automatic transmission, delivers smooth and predictable acceleration. While not as quick as the higher-powered G-Class variants, it provides sufficient power for everyday driving and highway cruising. The automatic transmission’s gear ratios are tuned for torque delivery, making it easy to maintain momentum on inclines and navigate challenging off-road conditions. Compared to the manual transmission versions of the G 280 CDI, the automatic offers greater convenience, particularly in urban environments. However, it does result in a slight reduction in fuel economy and a less engaging driving experience for enthusiasts. The long wheelbase contributes to a more stable ride, both on and off-road, but also makes the vehicle feel larger and less nimble in tight spaces.
Equipment & Trim Levels
The Edition.PUR trim level added a degree of refinement to the utilitarian G-Class. Standard features typically included air conditioning, power windows, central locking, and a basic audio system. The interior was typically upholstered in durable cloth or leatherette, with a functional and straightforward dashboard layout. The Edition.PUR package often included upgraded interior trim, such as wood or aluminum accents, and potentially special edition badging. Optional extras could include a sunroof, upgraded audio system, heated seats, and parking sensors. The long wheelbase provided ample space for passengers and cargo, making it a practical choice for families or those needing to transport equipment.
Chassis & Braking
The G 280 CDI Edition.PUR utilizes a robust ladder-frame chassis, a hallmark of the G-Class design. This construction provides exceptional strength and durability, essential for off-road use. The suspension consists of coil springs and rigid axles front and rear, offering significant wheel articulation and absorbing bumps effectively. The braking system features disc brakes on all four wheels, providing adequate stopping power for the vehicle’s weight. Anti-lock braking system (ABS) was standard, enhancing safety and control. Steering is handled by a recirculating ball system with hydraulic power assistance, providing a direct and responsive feel.
Market Reception & Comparison
The G 280 CDI Automatic was generally well-received by critics as a capable and practical off-road vehicle. Its diesel engine offered good fuel economy for its size and class, and the automatic transmission made it easy to drive in a variety of conditions. Compared to the more powerful G 500 or AMG variants, the G 280 CDI was positioned as a more affordable and sensible option. It also offered a more refined driving experience than the basic commercial versions of the G-Class. However, some critics noted that the automatic transmission could feel sluggish at times, and the interior was relatively spartan compared to other luxury SUVs.
Legacy
The OM 642 engine family, including the OM 642.975 found in the G 280 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can easily exceed 200,000 miles. The W461 G-Class, as a whole, has developed a strong following among enthusiasts, and well-maintained examples are highly sought after in the used car market. The G 280 CDI Automatic, while not the most common variant, offers a unique combination of capability, efficiency, and affordability, making it an attractive option for those seeking a classic and iconic off-road vehicle. Its simplicity and robust construction contribute to its long-term reliability and appeal.
