What is the fuel consumption of the G-Class?
3 Answers
The following is an introduction to the fuel consumption of the G-Class: 1. The Mercedes-Benz G-Class has a fuel consumption of approximately 18.5 liters per 100 kilometers. With aggressive driving, the fuel consumption can easily exceed 20 liters per 100 kilometers. 2. The Mercedes-Benz G-Class is a rugged off-road vehicle from Mercedes-Benz, equipped with a 4.0-liter twin-turbocharged V8 engine, paired with a 9-speed automatic transmission. 3. The fuel consumption of a car varies slightly depending on each driver's habits and skills. A smoother driving style results in lower fuel consumption, while aggressive driving, frequent overtaking, and high-RPM operations will appropriately increase fuel consumption. Additional information: The following are methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance may lead to higher fan speeds and lower temperatures to achieve a cooling effect. 2. Frequent hard braking: Frequent hard braking is a primary reason for persistently high fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement vehicles: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately upon entering. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside the vehicle. After the vehicle has cooled down moderately, then turn on the air conditioning.
Actually, few G-Class drivers keep an eye on the fuel consumption gauge, but since you asked, my long-term real-world data shows: the G500 typically starts at 16-18L/100km in city driving, while highway mileage can drop to around 12L. Last time I took a friend’s modified G63 with all-terrain tires off-roading, the meter jumped straight to 23L/100km—the roaring engine sounded like burning money. But people who buy this car care more about its three differential locks and chassis. The boxy design creates high drag, and the V8 engine is particularly thirsty—the 100L fuel tank exists precisely to minimize gas station visits. If fuel efficiency is a priority, the G-Class isn’t for you; it exists to conquer rough terrain.
There's an old G350d parked in my underground garage, and the dashboard shows 14.5L diesel consumption during daily commutes. Once I chatted with a neighbor who drives a G500, and he said it easily exceeds 20L gasoline in traffic jams. The fuel consumption of the G-Class varies greatly depending on the version, with the diesel version saving about one-third. After the facelift, the G500 was equipped with a 48V mild hybrid system, which can shut down four cylinders during start-stop, but it only saves about 0.5L. The key point is that this car weighs 2.5 tons, has a high drag coefficient of 0.44 due to its tall body, and very wide tires. These physical characteristics alone make it inherently fuel-thirsty. If you're really considering buying one, I'd recommend the diesel version—its fuel tank can last up to 900 km on long trips.
