Because K5 has all-wheel drive and sits on a relatively short 2844-mm wheelbase, Dan Ahearn, Tahoe's other assistant brand manager (this time for marketing), suggests it's a more maneuverable package that would enable its owners to reach more remote locations. It would also make it easier to go over those cement parking lot curbs and load kids in a tight space, but there's little SUV mystique in that.
At the moment the K5 is a concept vehicle, but given GM's aggressive recent policy to put concepts into production and because the SUV simply will not stop evolving, there seems like a fairly good chance that either this model or something very much like it will actually see production in a year or so.
