Believe the figures and you’ll think a 3-litre V6 Q7 will manage almost 40mpg if driven with a modicum of circumspection. It won’t. These numbers reveal everything about the ridiculous and unrealistic way at which they are arrived (and in which Audi has no choice) and nothing whatever about the likely fuel consumption of the Q7.
As previous stated we’d not expect the lower powered V6 to actually use substantially less fuel than its stronger sister and in both cases if you’re beating 30mpg in normal driving you’re doing well.
Push either harder than it cares to go and you can wipe 10mpg off that number in very short order indeed. As for the V8, the claim of 30.7mpg is probably slightly less of a fantasy figure though you’ll still be doing well to get close to it: we’d reckon 25mpg is what to expect in normal driving.
Still at least the 5.9-litre V12 TDI version is no longer on sale: you’d have struggled to get that out of the teens. All Q7s have the same massive 100 litre fuel tank so even the V8 should cover over 450 miles on a tank, the V6s over 550 miles.
All Q7s hold onto their value if not with the vice like grip of a Cayenne, then certainly with the tenacity that is characteristic of this class. Just remember all bar base SE model Q7s are well equipped and resist the temptation to be too trigger happy with the options box, a sure fire way of turning the Q7 into a depreciation nightmare.
