The Mercedes-Benz G500, a high-performance luxury SUV, has an official combined fuel consumption of around 12.4-13.3 litres per 100 km (approximately 21.2-21.7 mpg). Real-world driving conditions, such as urban traffic or motorway cruising, can push this figure higher—often between 15-18 litres per 100 km (16-19 mpg). The G500’s 4.0-litre V8 biturbo petrol engine delivers strong acceleration (0-62 mph in 5.9 seconds) but prioritises power over efficiency.

For context, the G500’s fuel economy is significantly lower than smaller SUVs like the BMW X5 or hybrid models such as the Lexus RX 450h. Factors like driving style, load, and terrain impact consumption. Owners report higher figures in stop-start city driving, while steady motorway speeds yield slightly better results.

If fuel efficiency is a priority, consider the Mercedes-Benz G350d (diesel variant), which offers better mileage. The G500 suits those prioritising performance and prestige over running costs. Always check the latest WLTP figures for updated data, as emissions regulations and engine tweaks can affect published numbers.

The fuel consumption of the Mercedes-Benz G500 is 16.8 liters per 100 kilometers. The actual comprehensive fuel consumption depends on multiple factors such as load, road conditions, driving habits, weather, wind speed, tire pressure, etc. The actual comprehensive fuel consumption should be based on real driving conditions.

Factors affecting fuel consumption:

Engine displacement and fuel consumption are somewhat related, but higher fuel consumption does not necessarily mean larger displacement. In relative terms, the size of a car's engine displacement does not directly correlate proportionally with fuel consumption. Besides engine displacement, factors such as the car's design, weight, and engine technology also significantly influence fuel consumption.

Solutions for high fuel consumption:

Correct improper driving habits, maintain steady acceleration, avoid coasting in neutral, reduce vehicle load, and ensure regular maintenance and inspections. Address any issues promptly upon discovery.

From an engineering perspective, the G500’s fuel consumption is typical for a large-displacement V8 petrol engine in a heavy, boxy SUV. Aerodynamic drag and weight (2.5+ tonnes) play major roles. The 4.0-litre biturbo engine’s advanced tech (like cylinder deactivation) helps marginally, but physics dictates high consumption. Expect 13-18 litres per 100 km depending on use.
