Popular Mechanics posted this picture of a lineup of KJ's recently. Here's what they had to say about it:

Here's the best look yet at the next Jeep Cherokee. This caravan of prototypes was caught during a road trip through northern Michigan. The photos show what we have been hearing about all along: a taller cabin, short front and rear overhang, outside mounting for the spare wheel and a more aerodynamic windshield. Also look for more entrance space for rear-seat passengers, a longtime Cherokee liability, and a more rounded body, mostly due to the curves in the side glass. Three kinds of wheels are shown here.
