I've read that there may actually be a folding rear window or something... Perhaps what Jeep does is make the roof a skeleton structure and then add removable panels offering an open air cockpit that is more rigid??
the bod you're looking at in the OP pic is the current wrangler. That seems more a powertrain and chassis mule...The matte black panels are probably removable but it will definitely be more of a hassle than if you were to remove a soft top. Unless it's separated into 6 individually removable pieces instead of one solid piece.
4 inches narrower (track width and fender change)
1.5 inch lower body (suspension up inside the body but the same overall height)

yea but then you get long and narrow which is more tippy off track. Depends on how much they narrow track width...This width reduction may be there to make up for a possible length increase due to the TorqueFlite 8 speed transmission.
