The 2022 Mercedes-Benz G63 has a fuel tank capacity of 100 liters. The 2022 G63 is equipped with a 4.0-liter twin-turbocharged engine, paired with an automatic transmission (AT). The vehicle features a front-engine, four-wheel-drive layout and a front suspension system with double wishbone independent suspension. In the same vehicle class, the 2021 Maybach GLS 480 4MATIC has a fuel tank capacity of 85 liters, while the 2020 Mansory Range Rover 3.0T Black Carbon has a capacity of 104 liters. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount may exceed the marked capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with 'E' (Empty) and 'F' (Full). When the needle is close to 'E,' it indicates low fuel, while near 'F' means the tank is nearly full.

I've driven the Mercedes-Benz G63, and its 100-liter fuel tank is really huge! This car is especially worry-free on highways, as a full tank can cover over 500 kilometers, making long-distance trips almost refuel-free. Last time, I went on a road trip to Tibet with friends, and while others carried spare fuel cans, I relied on this 100-liter tank all the way. However, the fuel consumption in the city is higher, around 18 liters per 100 kilometers, but the refueling frequency is lower—I only refuel every two weeks. It's best to refuel when the fuel gauge shows a quarter left to protect the fuel pump.
