Passengers in the back are treated to first-class levels of comfort, too – especially in the long-wheelbase 'L' version, which of course provides even more room to stretch out your legs.
There's actually slightly more space than in the back of an equivalent Mercedes S-Class or BMW 7 Series, but frankly all three are ridiculously roomy. The optional electrically adjustable rear seats give you the ability to tailor your seating position for using a laptop, a snooze and anything in between.
All A8s offer decent interior storage, too. There are two cupholders in the front and two in the back, plus a rear central armrest and deep door pockets.
For those who love a stat, the boot's capacity is 505 litres. But that’s just a number, so what does it mean in practice? Well, it means the load bay is roughly the same size as the Mercedes S-Class's and is therefore big enough to hold eight carry-on suitcases. It also means there’s room enough for a couple of sets of golf clubs, should you and a chum fancy a quick round between important business meetings.
You can fold down the rear seats if you need more luggage space, but annoyingly the whole seatback folds in one big piece (there's no 60/40 split).
