According to Autoline Daily, the Grand Cherokee platform cannot be properly re-engineered to support the full-size Grand Wagoneer.
With that said, Jeep hasn’t given up on the new three-row SUV entirely, with the automaker looking at using the body-on-frame platform utilized by the Ram 1500 in such an application. This seems like a low-effort solution, however, especially when the Grand Wagoneer was previously touted as a Land Rover-fighter.
Jeep leaders said previously that the Grand Wagoneer would be the “pinnacle of premiuim,” while an alleged Wagoneer would be a less luxurious variant. FCA CEO Sergio Marchionne even had plans to build the family of full-size SUVs at its Warren Truck Assembly plant in Detroit before putting them on sale in 2019 or early 2020.
In September it was reported FCA was reevaluating its plans for Warren Truck Assembly due to the costs associated with changing it from a body-on-frame pickup line to a unibody line. Marchionne described the facility as a “very old plant,” that needs “significant investment.”
