Cause why the fuck not
We first heard of the return of the Jeep Wagoneer and Grand Wagoneer just over two years ago, but since then, further details have been scarce. Early reports showed that these two SUVs could be built on an extended version of the unibody Grand Cherokee platform, but news of a retooling at Fiat-Chrysler's Warren Truck Assembly plant stoked rumors that the Wagoneer and Grand Wagoneer might be destined for a variant of a Ram pickup truck frame. Now a leaked document seems to indicate one particularly wild version of the big luxury Jeep.
An internal document from German powertrain component maker ZF makes mention of a new Jeep model with the platform designation WS—which Allpar previously reported as the internal name for the upcoming Wagoneer. The ZF document, which dates to the beginning of this year, shows a list of 2018 production and pre-production vehicles using versions of the ZF 8HP eight-speed automatic transmission.
The section pertaining to the Jeep Grand Wagoneer confirms that the platform will be called WS and will utilize a version of the 8HP transmission. Puzzlingly, it also refers to a model called the "Grand Wagoneer Trackhawk," which, according to the document, dates back to April and May of 2017. The ZF document indicates that the Grand Wagoneer Trackhawk uses a 6.2-liter V8 making 729 PS, or roughly 718 horsepower—a number that's nearly identical to the 717-horsepower output of the updated-for-2019 Dodge Challenger SRT Hellcat.
The transmission code listed for the Grand Wagoneer Trackhawk is ZF-8HP95X, which denotes a high-torque variant of the 8HP. This transmission is currently used in the Grand Cherokee Trackhawk, as well as the Rolls-Royce Cullinan, as shown below. No other variants of the Wagoneer or Grand Wagoneer are listed in the ZF document.
What could this mean? When reached by Road & Track, an FCA spokesperson denied knowledge of any plans for a Hellcat-powered Grand Wagoneer.
We see a few possibilities here. Perhaps FCA built a handful of Grand Wagoneer prototypes with the supercharged 6.2-liter Hellcat engine for testing purposes in 2017, then abandoned the project. It's also possible that the vehicles indicated in the ZF document were really prototypes for an updated Grand Cherokee Trackhawk with the 717-horsepower engine (though such a vehicle has not been confirmed by FCA). Perhaps it's just a tantalizing typo, an error on ZF's part that we're reading far too much into.
Whatever it is, we like the sound of it. A three-row SUV with the heart of a Hellcat sounds like a great way to haul six or seven people around swiftly.
