The Cayenne might be large for a Porsche, but it’s not as practical as some other big 4x4s because there’s less shoulder room and it forces a central rear passenger to straddle a lump in the floor.
You can’t specify a third row of seats, either, but it’s comfortable for four adults, and the rear seats slide back and forth on runners so you can enlarge the boot when smaller children are sitting in the back.
With the seats all the way back, the boot isn’t as large as a BMW X5’s or a Range Rover Sport’s. But it can still swallow a couple of large suitcases easily enough. You can also fold down the rear seats to expand the load area, and models fitted with air suspension allow you to lower the rear of the car to make it easier to load.
