It appears obvious that they've done some tinkering with the rear, otherwise they wouldn't have it so covered up. Every spy shot I've seen has the rear quarters well hidden. I have to assume they've lengthened the rear deck thus giving the appearance of a longer, slimmer rear end. All good in my opinion. What puzzles me about the spy photos is that the car seems to be higher off the wheels than the concept and the rear wheels seem to be smaller than the front. I'm hoping that the final production car will be as low as the concept with at least some of the fairings from the concept.
