Not only that, but the brand was thinking about it with the just-launched-for-2019 Hellcat engine. The ZF document lists 729 PS for the engine in the Jeep, or a hair shy of 718 horsepower — just one off the figure for the 2019 Charger and Challenger Hellcats. The listed production dates mean ZF planned for a build run of April 2017 to May 2017. The document also mentions the Rolls-Royce Cullinan with two sets of build dates: from January 2016 to February 2016, and from December 2017 to January 2018. That sounds like a run of prototypes, which could be how the Grand Cherokee Trackhawk got included in the paperwork. The document didn't reference any other Wagoneer versions.
A Hellcat-powered Grand Wagoneer would make sense. The new luxo-Jeep will be built on a modified Ram platform at the Warren Truck Assembly Plant, and we know Ram's working on a Hellcat-bound Ram 1500 TRX. And the now-iconic engine in an SUV that hopes to become a new icon would be a treat for dealers who wonder if the Grand Wagoneer will arrive too late to succeed.
Again, this doesn't mean we'll see anything of the kind. Chrysler also evaluated a 300 Hellcat, but nothing's come of it. And with the standard Wagoneer still several years away — the renovations at the Warren plant aren't due for completion until 2020 — any hi-po version could wait another year after launch, were such a thing to happen.
