What is the fuel consumption of the G63?

[Winifred]

The official combined fuel consumption of the Mercedes-Benz G63 is 11.9L per 100km, while the actual fuel consumption depends on various factors such as the driver's habits and road conditions. Here are some details about the Mercedes-Benz G63: 1. Body dimensions: The G63 measures 4864mm in length, 1984mm in width, and 1974mm in height, with a wheelbase of 2890mm. 2. Powertrain: It is equipped with a 4.0L twin-turbocharged V8 engine, delivering 585 horsepower and a maximum torque of 850 Nm. This engine reaches its peak power at 6000 rpm and its maximum torque between 2500 to 3500 rpm. The engine is paired with a 9-speed automatic transmission.

I've been driving the G63 for two years now, and the fuel consumption is indeed quite high. In city traffic jams, it can go over 20L, and watching the fuel gauge drop when starting from a traffic light is heartbreaking; on the highway with cruise control, it's around 15L, but even then, a full tank doesn't last very long on long trips. My long-term average fuel consumption is stable at 18L/100km, and in summer with the AC on, it adds another 2L. Other owners in the group are at similar levels—after all, with a 4.0T V8 engine and a weight of two and a half tons, saving fuel is impossible. But as for whether it's worth it, every time I step on the gas and hear the roar from the exhaust, I feel like the fuel consumption is totally justified.

From a technical perspective, the high fuel consumption of the G63 is primarily due to three inherent flaws: Firstly, the 4.0-liter large-displacement engine is inherently fuel-thirsty—585 horsepower doesn't come for free. Secondly, its boxy design results in a drag coefficient comparable to a brick, leading to significant wind noise at high speeds and a sharp increase in fuel consumption. Thirdly, the full-time four-wheel-drive system consumes approximately 20% more fuel than a standard two-wheel-drive vehicle. Based on my real-world testing, gentle driving yields a combined fuel consumption of around 17L, but a slightly more aggressive approach easily pushes it beyond 20L. Fortunately, the 98-liter large fuel tank helps alleviate range anxiety, though frequent gas station visits are inevitable, with monthly fuel costs typically ranging between three to four thousand.

If you're concerned about the G63's fuel consumption, just take a look at its competitors: the Cayenne Turbo averages 13L/100km, and the Range Rover Sport 14L/100km, both more fuel-efficient than the G63. But the G63 can effortlessly climb 60-degree slopes and traverse artillery shell craters as if they were flat ground – feats other SUVs can't match. I originally bought it because I love its boxy design and AMG exhaust note, treating the high fuel consumption as a 'personality tax.' After all, three years' worth of fuel costs only about 100,000 yuan, less than 5% of the car's price. Those who truly love this car won't fret over the numbers on the fuel gauge.

Honestly, saving fuel with a G63 is quite challenging, but there are some tricks to avoid wasting money. From my experience: in the city, try to use Comfort mode as Sport mode can spike fuel consumption by 30%; maintaining a steady 110 km/h on the highway is the most economical; keeping tire pressure at 2.8 saves about 5% more fuel than the standard value; also, avoid leaving the roof rack empty—removing it reduces wind resistance. These methods helped me reduce consumption from 23L to around 18L. But let's be real, if you've chosen a V8-powered car, obsessing over fuel economy isn't the point—enjoying the thrilling acceleration is what really matters.

The fuel consumption difference between off-road and on-road driving in the G63 is particularly significant. Last month, when I took it to the desert for off-roading, with tire pressure reduced to 1.2 bar and all four-wheel-drive locks engaged, the fuel consumption skyrocketed to 30L/100km. However, during cruising on paved roads, it stabilizes around 15L. The most frustrating part is during cold starts; at -10°C in winter, the instantaneous fuel consumption shows 99.9L upon ignition and only returns to normal after driving two or three kilometers. Therefore, it's advisable for frequent off-roaders to install an auxiliary fuel tank, as the original 98-liter tank only allows for about 300 kilometers in the desert before needing a refuel.
