The Mercedes-Benz G 300 Long (W463), produced from September 1993 to March 1997, represents a significant iteration of the iconic G-Class, blending off-road capability with a degree of luxury. Positioned as a mid-range offering within the W463 series – which spanned from the G230 to the high-performance G55 AMG – the G 300 Long catered to buyers seeking a robust, capable vehicle with a more accessible price point than its higher-powered siblings. The “Long” designation refers to the extended wheelbase, providing increased rear passenger space, making it a popular choice in markets where carrying passengers was a priority. This variant was primarily sold in Europe and other international markets, and was not officially offered in the United States during its production run.

Powertrain & Engine Architecture
The G 300 Long was powered by the M103.987, a 3.0-liter inline-six cylinder gasoline engine. This engine, a mainstay of Mercedes-Benz’s mid-range offerings in the 1980s and 90s, featured a single overhead camshaft (SOHC) valvetrain and Bosch multi-port fuel injection. The M103 was known for its durability and relatively smooth operation, though it wasn’t a particularly high-revving engine. Its 170 horsepower and 235 Nm (173 lb-ft) of torque were adequate for the G-Class’s substantial weight, but didn’t deliver particularly brisk acceleration. The engine’s longitudinal mounting and the 4MATIC all-wheel-drive system contributed to the G-Class’s inherent off-road prowess. The four-speed automatic transmission, while providing ease of use, wasn’t known for its efficiency or particularly quick shifts. It was a common transmission for Mercedes-Benz vehicles of the era, prioritizing reliability over outright performance.
Driving Characteristics
The G 300 Long Automatic offered a driving experience distinctly different from its more powerful counterparts. Acceleration was leisurely, taking approximately 14.8 seconds to reach 62 mph (100 km/h). The automatic transmission, while convenient, resulted in a noticeable loss of responsiveness compared to the available manual transmission. The gear ratios were geared towards providing sufficient torque for off-road situations rather than maximizing on-road speed. However, the G 300 Long excelled in off-road conditions, where its robust construction, all-wheel-drive system, and low-range gearing allowed it to tackle challenging terrain with confidence. The long wheelbase provided a more stable ride on paved roads, but also slightly reduced maneuverability in tight spaces.
Equipment & Trim Levels
The G 300 Long typically came equipped with a relatively basic level of standard features, reflecting its positioning as a more affordable G-Class variant. Standard equipment included power windows, central locking, and a basic audio system. Interior upholstery was typically cloth, though leather was available as an option. Optional extras included air conditioning, a sunroof, and upgraded audio systems. The dashboard layout was functional and utilitarian, prioritizing durability and ease of use over aesthetic flair. The extended wheelbase provided ample rear passenger legroom, making it a comfortable option for families or those frequently carrying passengers.
Chassis & Braking
The G 300 Long retained the G-Class’s traditional body-on-frame construction, providing exceptional strength and durability. The suspension consisted of coil springs and rigid axles front and rear, offering a comfortable ride and excellent off-road articulation. Front brakes were discs, while rear brakes were drums – a cost-saving measure common in this era. ABS (Anti-lock Braking System) was standard, enhancing safety on paved roads. The steering system utilized a cone worm and recirculation balls mechanism, providing a direct but somewhat heavy steering feel. The tires, typically 205/80 R16, were chosen for their durability and off-road capability.
Market Reception & Comparison
The G 300 Long was generally well-received by critics as a capable and practical off-road vehicle. However, its relatively modest performance and basic interior were often noted. Compared to the G230, the G 300 Long offered a significant power increase, but at a higher price point. Compared to the more powerful G360 or G55 AMG models, the G 300 Long was considerably less expensive but lacked the same level of performance and luxury. Fuel economy was relatively poor, averaging around 19 l/100 km (12.4 US mpg) in urban driving and 13.4 l/100 km (17.6 US mpg) on the highway. Reliability was generally good, thanks to the robust construction and proven M103 engine, but maintenance costs could be high due to the vehicle’s complexity and the availability of parts.
Legacy
The G 300 Long (W463) has become a sought-after classic among G-Class enthusiasts. The M103 engine, while not the most powerful, is known for its durability and relative simplicity, making it easier to maintain than some of the later, more complex G-Class engines. Well-maintained examples command a premium in the used car market. The G 300 Long represents a sweet spot in the G-Class lineage, offering a blend of off-road capability, practicality, and relative affordability. Its enduring appeal is a testament to the G-Class’s timeless design and legendary reputation.
