Having mulled it over, I have concluded that I don't quite get it.
From its inception the Discovery was always the comfortable, passenger-orientated vehicle while the Defender was the utility vehicle.
This seems to have the target market of the Discovery while still pretending to have utility credentials, however the load space looks to be wrong. The back of an 88" is not enormous, but it is big enough to carry stuff (a few sheep?) and this carried over to the Defender. However, I note that none of the pictures really show the load space and if you look at the side view the door is longer than the space behind, indicating that actually it is very small. The LWB may be a bit better but I doubt it with a second row of seats, which essentially makes it more like a car boot than a true carrying space. If this is correct then it is competing directly with other SUVs or for the SWB not even that as it won't serve as the family vehicle. I therefore don't see where it is targetting, except the 'site foreman' or 'site engineer' market which is a bit small I would have thought to achieve the market penetration necessary.
I also happen to think that the side-on view with the door longer than the rear space is rather ugly, but each to their own.
