G500, with a 5.5L displacement and automatic transmission, has an average fuel consumption of 21L/100km as reported by netizens, and a comprehensive fuel consumption of 15.7L/100km under the Ministry of Industry and Information Technology's standard conditions. Below are the relevant details: Positioning: The Mercedes-Benz G500 is the flagship model of the Mercedes-Benz G series. This purebred off-road vehicle is equipped with Mercedes-Benz's latest generation 5.0L V8 engine, delivering a maximum power of 216kw/5500rpm and a maximum torque of 456nm/2800-4000rpm. Power: The installation of a supercharger enables it to unleash 80% of its maximum torque at around 1800rpm. Combined with a ladder frame non-independent suspension and three differential locks (front, center, and rear, all capable of 100% locking), the G500 boasts formidable off-road capabilities. However, this does not mean the vehicle loses its on-road performance. When pushing its nearly three-ton body, it still achieves an impressive 0-100km/h acceleration time of 10.2 seconds.

I've been driving the G500 for almost three years now, and the fuel consumption is indeed quite high. In city traffic jams, it can reach up to 18 liters, while highway cruising is better at around 13 liters, averaging about 15 liters overall. This is mainly due to the 4.0T V8 engine under the hood and the boxy design that creates significant wind resistance. My friend's Range Rover also consumes about 14 liters, which shows that luxury off-road vehicles are generally like this. I usually fill up with 95-octane fuel, spending over 2,000 yuan a month on gas. However, people who buy this car value its off-road performance and commanding presence more. I recommend installing a tire pressure monitoring system, as insufficient tire pressure can increase fuel consumption by 1-2 liters.

After studying the fuel consumption data of the G-Class, the G500's actual combined fuel consumption ranges between 14-17 liters. The main reason is its high drag coefficient of 0.54, which consumes 30% more fuel than streamlined SUVs. During a test drive on National Highway 318, the instantaneous fuel consumption reached 25 liters when fully loaded and climbing. However, the roar of the 8-cylinder engine and its off-road capabilities make you feel the fuel consumption is worth it. For daily use, it's recommended to turn off the sport mode, which can save about 1.5 liters of fuel. Additionally, the 100-liter fuel tank is sufficiently large, allowing a range of over 600 kilometers on a full tank.

Friends who own the G500 all say it's a gas guzzler, with city commuting typically starting at 16 liters per 100km. Last time I went off-roading with a buddy, the fuel consumption on unpaved roads shot up to 22 liters. But that's just how big-displacement engines are—the 4.0T squeezing out 421 horsepower naturally comes with high fuel consumption. In comparison, the Cayenne Turbo also averages around 15 liters. To save some fuel, maintain a steady speed and avoid using paddle shifters for aggressive driving. Remember to service the air filter on time, as clogging it will increase fuel consumption even more.

Compared several hardcore off-roaders' fuel consumption, the G500 is indeed on the higher side. With a curb weight of 2.5 tons, it's 400kg heavier than a Wrangler, naturally consuming about 3 liters more. Stop-and-go city driving is particularly thirsty, with instant fuel consumption reaching 40 liters during traffic light starts. However, buyers of this vehicle typically don't focus much on fuel costs, valuing more the brought by its three differential locks. Personal tip: waiting for RPM to stabilize after cold starts before driving can effectively reduce high fuel consumption in the first 10 kilometers.

When I first got the G500, I was shocked by the fuel consumption, but now I'm used to it. Pure city driving consumes 18 liters, highway driving 12 liters, and the combined average is about 15 liters per 100 kilometers. Displacement and vehicle weight are the drawbacks, but the effortless feeling of the V8 engine is something smaller engines can't provide. I've talked to a friend who drives a G63, and his fuel consumption is about 3 liters higher. To save fuel, brake less and anticipate road conditions more. Also, using air conditioning in summer increases consumption by about 1.5 liters, and remember to turn off the start-stop function when off-roading.
