Thankfully, the A7’s sloping roof doesn’t hinder interior space too badly. A couple of tall adults will have no problems with the room on offer in the front, while another couple will be able to sit behind them without their knees pressing against the front seatbacks (really tall folks will find their hair just brushing the rooflining, though). The Mercedes-Benz CLS is very similar in this respect and both cars are only really good for two adults in the rear, making the capacious BMW 6 Series Gran Turismo the one to go for if you regularly carry three rear passengers.
At 535 litres, the A7’s boot is slightly bigger than that in the CLS, and we squeezed on board a fine total of eight carry-on suitcases. And with good access through its wide-opening, standard powered tailgate, plus that usefully square shape within, it's easier to get bulkier items such as a pram inside. That said, with its even bigger boot, once again the 6 Series GT takes the spoils if you want something with a coupé silhouette that's still super-practical. You can always drop the standard 40/20/40 split-folding rear seats to increase the A7's practicality if needed, though.
Storage space for your odds and sods is pretty good, with the usual array of cupholders, door bins, cubbies and a good-sized glovebox.
