What is the fuel tank capacity of the G-Class in liters?

The fuel tank capacity of the Mercedes-Benz G-Class is 100 liters, as officially announced. Owners who have purchased the Mercedes-Benz G-Class can also check this information on the vehicle's configuration sheet. The G-Class requires 95-octane fuel, with a fuel consumption of 18.5L per 100 kilometers. A full tank can cover a distance of approximately 541km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
Last time I drove my friend's G500 on a long trip and realized the fuel tank is really huge. I checked the manual and it's 96 liters. When our team goes off-roading, the most important thing we look for is range, and with this large tank, you can drive nearly 600 km on a full tank. However, the new G63 has been reduced to 90 liters, reportedly to balance the vehicle weight. If you're heading into uninhabited areas, it's advisable to carry spare fuel cans. Some off-roading friends have even modified their vehicles with auxiliary fuel tanks, though this might affect the annual inspection.
The Mercedes-Benz G-Class fuel tank varies by engine displacement: the standard version features a 96L aluminum alloy tank, ensuring a range of 700 km. Once at a repair shop, I watched a technician work on a G-Class and specifically asked about the tank material—it has a cold-rolled steel inner layer with a special coating to prevent oil leaks from scrapes on rough terrain. This design is quite practical, though removing the tank for maintenance requires disassembling the exhaust pipe, making labor costs quite high.
