Space in the front of the 8 Series Gran Coupé is fine for two taller adults and certainly on a par with the competition. It’s quite broad inside, too, so you can spread out across the centre armrest without spilling into your passenger’s space. There’s also plenty of storage space for your odds and sods.
Now for the important question: how spacious is the rear? Well, you get two proper seats and an occasional middle seat that’ll be quite awkward to sit on for long periods; its occupant has to straddle a large hump in the floor. The two outer seats, meanwhile, are supportive and offer similar space to the CLS’s. In other words, there isn’t a lot of under-seat foot space, but six-footers will have enough room to sit behind tall front seat occupants. Head room is marginal, but so far we’ve tried only an example fitted with a space-sapping sunroof. The Panamera and A7 Sportback both offer more all-round lounging room, though.
You can fold down the rear seatbacks in a 40/20/40 configuration using handy release levers in the boot. Doing so gives you a fairly flat extended load bay, but there’s room for around five carry-on suitcases, even with the rear seats in use. The boot isn’t as big or conveniently shaped as the A7 Sportback’s and is afflicted by a higher load lip and a narrower aperture.
