The Cayenne has the most leg and head room up front of its key rivals, even surpassing the Range Rover Sport by a fraction, although it is a slightly narrower cabin and the high central spine means it feel quite snug. The centre console offers a useful storage space for your phone or a small bottle, while the door pockets will hold a 1.0-litre bottle.
Two cupholders pop out of the dash area in front of the passenger. These are adjustable and are big enough to cope with all but truly enormous takeaway mugs, and are well placed high up out of the way of the rest of the centre console.
Porsche Cayenne rear space
Good for two adults
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’.
Porsche Cayenne seating flexibility
Fine by five-seat standards, but some rivals offer seven seats
A 40/20/40 split rear seat bench means you can drop one, two, or three of the rear seats to load longer items and still seat passengers. The seats are easy to fold, too, although you have to do it manually from the side doors because there are no buttons or levers in the boot to fold the seats. When they are dropped, the seats leave a slight step up in the load bay.
The passenger gets an electrically adjustable seat just like the driver, even in base cars, and gets lumbar adjustment optionally, or as standard in the Hybrid and Turbo models.
Porsche Cayenne boot space
Standard powered tailgate, and a big – if not the biggest - boot
The Cayenne doesn’t have the biggest official boot capacity in the class – a Range Rover Sport betters it – but the tape measure shows that in practical use the Porsche actually offers a wider and deeper boot, and it gets a powered tailgate as standard. It’s certainly big enough for heavy-duty family use, and the floor is flush with the boot entrance, although the boot lip is still fairly high because the Cayenne is an SUV.
