The Mercedes-Benz G 300 4MATIC, produced between September 1993 and August 1996, represents a significant iteration of the iconic G-Class (W463) series. Positioned as a mid-range offering within the G-Class lineup during its production run, the G 300 aimed to provide a balance between capability and relative affordability compared to the more powerful G 360 and the high-performance G 500. This variant was primarily marketed in Europe and other international markets, leveraging the G-Class’s established reputation for off-road prowess and robust construction. The G 300’s appeal lay in its blend of a capable engine, automatic transmission, and the legendary G-Wagen’s inherent durability.

Powertrain & Engine Architecture
The G 300 was powered by the M 103.987, a 3.0-liter inline-six cylinder gasoline engine. This engine, a mainstay of Mercedes-Benz’s mid-size and larger vehicles throughout the 1980s and early 1990s, was known for its durability and smooth operation. The M 103 featured a single overhead camshaft (SOHC) valvetrain, two valves per cylinder, and Bosch multi-port fuel injection. This configuration delivered a respectable 170 horsepower at 5500 rpm and 235 Nm (173 lb-ft) of torque at 4500 rpm. The engine’s longitudinal mounting and the permanent four-wheel drive system contributed to the G-Class’s exceptional off-road capability. The transmission was a four-speed automatic, providing relatively smooth shifts but prioritizing robustness over outright performance. This automatic transmission was chosen to broaden the appeal of the G-Wagen to drivers who preferred convenience over the engagement of a manual gearbox.
Driving Characteristics
The G 300 Automatic offered a unique driving experience. While not particularly quick – 0-60 mph took around 13.3 seconds – it provided ample torque for off-road excursions and comfortable cruising. The automatic transmission, while not offering the responsiveness of a modern gearbox, was well-suited to the engine’s characteristics. The gear ratios were optimized for low-speed crawling and maintaining momentum on challenging terrain. Compared to the manual transmission versions of the G 300, the automatic sacrificed some driver control and responsiveness, but gained in ease of use. Against the more powerful G 360, the G 300 felt noticeably slower, but its lower running costs and more manageable power delivery appealed to a different segment of buyers.
Equipment & Trim Levels
The G 300 typically came equipped with a relatively basic level of standard features, reflecting its positioning as a utilitarian vehicle. Standard equipment included power steering, ABS brakes, and a robust heating and ventilation system. Interior appointments were functional rather than luxurious, with cloth upholstery and a simple dashboard layout. However, a range of optional extras were available, including leather upholstery, air conditioning, power windows, and a sunroof. The G-Class’s interior was designed to withstand harsh conditions and prioritize durability over lavishness.
Chassis & Braking
The G 300’s chassis was a body-on-frame construction, renowned for its strength and rigidity. The suspension consisted of coil springs and rigid axles front and rear, providing excellent articulation for off-road driving. Front brakes were discs, while the rear brakes were drums – a cost-saving measure that was common for the time. The steering system was a recirculating ball type, offering a direct feel but requiring more effort than modern rack-and-pinion systems. The G 300’s robust chassis and suspension allowed it to tackle extremely challenging terrain with confidence.
Market Reception & Comparison
The G 300 was generally well-received by automotive critics as a capable and durable off-road vehicle. However, its relatively slow acceleration and basic interior were points of criticism. Compared to other G-Class variants, the G 300 offered a more affordable entry point into the G-Wagen world. Its fuel economy, while not exceptional, was better than that of the larger-engined models. Reliability was generally good, thanks to the robust construction of the engine and chassis. The G 300 appealed to buyers who prioritized off-road capability and durability over outright performance and luxury.
Legacy
The G 300 (W463) has developed a strong following among enthusiasts and collectors. The M 103 engine is known for its longevity, and well-maintained examples can still provide reliable service today. The G 300’s relatively simple mechanicals make it easier to maintain and repair than more complex modern vehicles. In the used car market, the G 300 commands a premium due to its iconic status and enduring appeal. It represents a sweet spot in the G-Class lineage, offering a blend of classic G-Wagen character and relative affordability.
