Let’s face it. If you’re buying an Audi SQ8, you couldn’t care less about fuel consumption. That said, it’s always interesting to see how efficient these luxobarges are in real life, especially ones that weigh 2,440 kilograms (5,379 pounds). This video from 1001cars provides a look at the SQ8’s juicy fuel consumption numbers achieved by the European-specification model, so the one fitted with the 4.0-liter V8 TDI engine.
At a constant speed of 56 mph (90 km/h), the Audi SQ8 TDI sips just 6.3 liters / 100 km (37.3 mpg US or 44.8 mpg UK), but this type of test illustrates the ideal conditions. Going up to 75 mph (120 km/h) obviously has a negative impact on fuel consumption, reaching 8.9 liters / 100 km (26.4 mpg US or 31.7 mpg UK). That’s still not too shabby considering the sheer weight of the SUV. Going even faster, at 87 mph (140 km/h), it bumps the fuel consumption to 10.8 liters / 100 km (21.8 mpg US or 26.2 mpg UK).
The test also involved driving the Audi SQ8 TDI in the city where it managed to consume a relatively low 9 liters / 100 km (26.1 mpg US or 31.4 mpg UK). However, the folks who did the test were easy on the accelerator pedal, which means hitting those numbers will be a bit tricky while driving the SUV without constantly checking fuel consumption.
If you’re wondering about the size of the fuel tank, the diesel performance SUV can swallow 85 liters of diesel. That should translate into long journeys on the highway without having to stop frequently to refill the tank.
However, the charts above show the SQ8 TDI is far from being the most efficient among large diesel vehicles. As a matter of fact, it’s almost the thirstiest model overall. Only the Mercedes GLE 450 needed more fuel on the highway.
It goes without saying the gasoline Audi SQ8 sold outside of Europe needs considerably more fuel to move all that metal. Some would argue the diesel is actually more suitable for such a vehicle considering it offers more low-end torque and sips less fuel.
