Mopar has inadvertently confirmed its presence.
In December last year, we got wind of the 5.7-liter Hemi V8 being replaced by a new inline-six engine. Then about a month ago, we learned that the new motor would be arriving imminently, which was followed by last week's news that the new engine would not, in fact, be replacing the Hemi but would be added as a new 500-horsepower option. While some will always prefer a V8 and will want to stick with it for as long as possible, others will gladly choose the straight-six because it produces more power. But where will the new engine find a home? Well, Jeep has quietly added the engine as an option for its 2022 Grand Wagoneer.
The new information was first reported by TFLtruck, with the original information coming via one of its readers who noticed the addition to the Grand Wagoneer's digital owner's manual. This manual gives owners details on what kind of capabilities to expect from the engine. Along with the confirmation of the engine option, known as the Hurricane, we also learn that Grand Wagoneers equipped with it will still be capable of towing 10,000 pounds, matching the peak figure of the Hemi V8. As usual, one needs to equip the Max Tow package to gain access to all this performance. Without the package, a regular 4x4 model with the Hurricane will manage 5,630 lbs and a 4x2 will do 5,850 lbs.
Other new information includes a warning to owners that the engine's turbo coolant pump may continue running for a long time after the motor has been shut off and that this is to be expected as part of normal operation. With such a high-output engine, the turbos will surely require a lot of additional care, so their cooling system runs on a separate circuit for as long as 20 minutes after shut-off. This will help protect the turbos themselves and the areas surrounding them. Unfortunately, Jeep hasn't told us how much power the new offering will produce in the Grand Wagoneer range, but we expect that the Grand model will get the High Output version with over 500 hp and 475 lb-ft of torque, while the regular Jeep Wagoneer will get the Standard Output motor with over 400 hp and 450 lb-ft of twist. Confirmation of this should be forthcoming very soon.
