1979-1987 PUCH G-modell (W 460) 240 GD (72 Hp)

The Puch G-Modell, specifically the 240 GD variant produced between 1979 and 1987, represents a pivotal point in the evolution of this iconic off-road vehicle. Falling under the W 460 chassis code, the 240 GD was designed as a robust and utilitarian vehicle, initially intended for military use but quickly gaining popularity in the civilian market, particularly in Europe and Australia. This model offered a diesel-powered alternative within the G-Modell range, prioritizing durability and fuel efficiency over outright speed. It occupied a middle ground in the lineup, offering a more affordable entry point than the gasoline-powered models while still providing the G-Wagen’s legendary off-road capability.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 240 GD is the Mercedes-Benz OM 616.936, a 2.4-liter inline-four diesel engine. This engine is a pre-chamber diesel, a design common in Mercedes-Benz diesels of the era. The pre-chamber design utilizes a small auxiliary combustion chamber connected to the main cylinder, improving cold-starting performance and combustion efficiency. The OM 616 is known for its incredible durability and relatively simple mechanical design. It features a cast iron block and head, and a robust crankshaft and connecting rod assembly. Fuel injection is mechanical, utilizing a Bosch inline plunger pump. The engine produces 72 horsepower at 3,600 rpm and approximately 127 lb-ft of torque. The 240 GD was exclusively offered with a four-speed manual transmission, a robust unit designed to handle the engine’s torque and the demands of off-road driving. An optional automatic transmission was not available for this specific variant.

Driving Characteristics

The driving experience of the 240 GD is defined by its ruggedness and torque-focused power delivery. With only 72 horsepower, acceleration is modest, and highway speeds require planning. However, the engine’s 127 lb-ft of torque, available from low engine speeds, provides excellent pulling power, making it exceptionally capable in off-road situations. The four-speed manual transmission requires deliberate shifting, but its robust construction and well-defined gear ratios contribute to the vehicle’s overall control. Compared to the gasoline-powered G-Modells, the 240 GD offers significantly better fuel economy, a crucial advantage for those using the vehicle for extended periods or in remote areas. Compared to later diesel G-Wagens, like the 300 GD, the 240 GD feels noticeably less powerful, but its lighter weight and simpler mechanicals contribute to a more direct and engaging driving experience. The gearing is optimized for low-speed crawling and tackling challenging terrain, rather than high-speed cruising.

Equipment & Trim Levels

The 240 GD was typically equipped with a spartan, utilitarian interior reflecting its original military purpose. Standard features included vinyl or cloth upholstery, basic instrumentation (speedometer, fuel gauge, temperature gauge), and a heater. Air conditioning was a rare option. The dashboard is typically constructed from hard plastic, designed for durability rather than luxury. Trim levels were minimal; the 240 GD was largely offered in a single specification. Optional extras included a sunroof, upgraded seating, and auxiliary lighting. The exterior typically featured steel wheels, a spare tire mounted on the rear door, and minimal chrome trim. The focus was on functionality and robustness, rather than aesthetic embellishments.

Chassis & Braking

The W 460 chassis is a body-on-frame construction, providing exceptional strength and torsional rigidity. The suspension consists of solid axles front and rear, with leaf springs providing a robust and durable ride. The 240 GD typically featured drum brakes on all four wheels, although some later models may have been equipped with front disc brakes. Steering is a recirculating ball system, providing a direct but somewhat heavy feel. The vehicle’s high ground clearance and short wheelbase contribute to its exceptional off-road capability. A heavy-duty steering damper was often included to mitigate steering kickback on rough terrain. Stabilizer bars were generally not fitted as standard, prioritizing suspension articulation over on-road handling.

Market Reception & Comparison

The 240 GD was well-received in markets where fuel efficiency and durability were highly valued. Critics praised its off-road capability and robust construction, but noted its lack of refinement and modest performance. Compared to the gasoline-powered G-Modells, the 240 GD offered significantly better fuel economy, making it a popular choice for agricultural and forestry workers, as well as for those seeking a reliable and economical off-road vehicle. Compared to the later 300 GD, the 240 GD was considered less powerful but more affordable and slightly lighter. The 240 GD’s simplicity also contributed to its reputation for reliability, as there were fewer components to fail compared to the more complex gasoline engines.

Legacy

The Puch G-Modell 240 GD has become a highly sought-after classic vehicle, particularly among off-road enthusiasts and collectors. The OM 616 diesel engine is renowned for its longevity, and well-maintained examples can still provide reliable service today. The 240 GD’s simple mechanical design makes it relatively easy to maintain and repair, even in remote locations. Values for well-preserved examples have been steadily increasing in recent years, reflecting the vehicle’s iconic status and enduring appeal. The 240 GD represents a unique chapter in the G-Wagen’s history, embodying the original spirit of the vehicle as a rugged, utilitarian, and exceptionally capable off-road machine. Finding original, unmolested examples is becoming increasingly difficult, as many have been modified or restored over the years.
