What is going on with these rear seats?

Ok I was looking (dreaming) about my next car when I saw this on pistonheads:

Look at the rear seats, I would have expected slightly more from a Porsche, is there a reason why they are designed like this?

Thats what I thought, but I've been in other 2+2s Skyline/Supra - and they still have proper attempts at rear seats even thought they are tiny. This just looks like the have carpeted over the inside of the bodywork! I suppose it could be weight saving, but I'd be embarrassed about it looking like that . .
