The Cayenne is fine in the back for two tall adults, and is much better than the coupe-like BMW X6, which has much less headroom. However, the Cayenne has a big, raised central tunnel that makes it uncomfortable for anyone sat in the middle, and there is no seven-seat option, which a Range Rover Sport or BMW X5 both offer.
Storage is adequate but unexceptional, with two map pockets, and door pockets that will easily take a 500ml bottle.
Access is good – as with any SUV, the roof and seats are high enough that you don’t have to duck down much to access a child seat. The door aperture is fairly big, too, although the doors don’t open as wide as some rivals’.
