The Wagoneer is expected to see the light of day sometime around the next Durango refresh. Which could mean the Wagoneer shares its underpinnings with the Durango/Grand Cherokee family. But its not so simple as slapping a new body on a longer WK2 platform.

Its also been rumoured that the WK3 series (GC, Durango, maybe Wagoneer) MAY, and I STRESS the MAY here, transition to a car based platform which sounds like it could be consolidation/harmonisation with Maserati's work on the LX platform, meaning the GC, Wagoneer and Durango could all be using a derivative of the Maserati Levante's Ghibli based platform.

Heavy suspension work would need to be put in to make that platform Trail Rated, but that should be of little consequence, as the current Durano/GC share a platform but no similarity in suspension. It's believed that the transition from WK2 to WK3 will be substantial.

From AllPar:

Or in other words a modular/scalable RWD platform, similar to VW's MLB/MQB system, as a way to fight costs and extract more margin.

That's a good way to go about it. It's what I have read to be the case with many other platforms from car makers. I just hope the differences they have from model to model are different enough and not all cookie cutter.

Seeing that the Maserati Levante is out already (in the UK as of this post, I think?) what are the odds that what we learn from it can apply to some extent to the Wagoneer?
