That’s a fair question, because the subject of towing limits is a pretty topical one right now as caravans get heavier and heavier and the police crack down harder on overloaded vehicles. That said, Audi makes no distinction between the towing capacity of its Q7 based on what accessories (including the moon-roof) are fitted.

But it definitely pays to remember that many vehicles, once hitched up to their heaviest legal towed load, can then be very close to their Gross Combination Mass (GCM) which is the mass of the trailer, the vehicle and everything in it including people, fuel, luggage and any aftermarket accessories fitted to it.

As an example, there’s one US-made ute on the market now that, when towing its maximum legal load, is so close to its GCM (has so little payload remaining) that it could only be legally operated by one small person with no luggage, nothing in the tray and no fuel in the tank.

From memory, that model Audi Q7 had the option of rear window sunshades which are a great addition and should really be standard on any car sold in Australia. In this model, the shades were manually operated so you need to grab a small tab and pull the blind upwards to fix it in place. If the tabs are missing, the shade may be broken or may have been removed by a previous owner, leaving just the empty slot in the door trim.

Some cars also had electronically-operated shades, so a check of the owner’s manual may reveal where the relevant button is located. If the shades are missing, you may be able to find an aftermarket replacement that uses the same factory mounting points. There are lots of aftermarket choices online.

Even though the Q7 is larger than the Q8 and shares much of the same technology, Audi justifies a considerably price hike on the Q8 due to its more sport-focused powertrain options which boost performance. The Q8 is available in V6, V8 or full-electric guises, with the choice of petrol, diesel, hybrid and battery electric powertrains. The Q7 is only offered in petrol or diesel, the majority of which are in V6 guises with one V8 option. The top-spec SQ8 shares much of its underpinnings with the Lamborghini Urus.
