I doubt it, at least not for a couple years. Grand Cherokee sells nearer to 200k/year in the US and some of those customers may be willing to pony up for a larger, more luxurious vehicle, but that is essentially the purpose of the Grand Cherokee L. Escalade is around 30k per year and Navigator is 15k-20k per year. Combining sales of the lower-trim Wagoneer with the Grand Wagoneer may help them achieve their target, but they will have to eat into the sales of non-luxury full-size SUVs like the Tahoe, Yukon, and Expedition which usually have loyal buyers. I think not offering 4WD on the Wagoneer Series I will hurt them a bit.
