I'd like some answers to those questions too.
And Eisenhauer, those pix are from the silver coupe at the Dallas show last Oct. You can see the power cord hanging down from the trunk area. Oh, and you can see the silver too. If the production model will be 95% the same as the coupe, you can expect pretty much everything you see in those pix to be the same. I know...I know...true dual exhaust. I pray it stays!!!
But, looking back to the mule pix, IMO they do look similar from what you can see on the back end of the mule. Those two "boxes" at the back of the mule could be used to disguise the mufflers from the concept breaking up the "look" of what we know on the concept. I don't know...but makes sense to me.
