2022 Jeep Grand Wagoneer Will Get Twin-Turbo I6, Mopar Quietly Confirms

It'll tow a maximum of 10,000 pounds, too.

Stellantis’ new 3.0-liter, twin-turbo Hurricane inline-six—a.k.a the “Mopar 2J”—is finally here. According to the automaker, it’s headed into a whole bunch of products across several brands in North America in two key configurations: high output and standard output. We don’t know every car and truck these motors will go into just yet, but now we know almost for certain that a version of the engine is bound for the Wagoneer, Jeep’s range-topping and currently V8-powered SUV.

The fact was unearthed by TFLtruck, which was tipped off of the info by a reader. It’s sourced from an updated section of the car’s digital owner’s manual, which gives details of the truck’s characteristics and capabilities when it’s equipped with the engine. So yes, not only is the drivetrain all but officially confirmed for the Wagoneer, but we have some information about its performance as well.

The headline figure is that the Wagoneer’s available 10,000-pound towing rating is still upheld with this new engine, at least when the truck is equipped with the “Max Tow” package. If it isn’t, a standard 4×4 Wagoneer with the Hurricane can only pull 5,630 lbs, or 5,850 when built as a 4×2—the lowest towing figure in the range. That’s because currently, the Wagoneer’s smallest engine offering is the 5.7-liter Hemi V8 with a mild hybrid system. 

The supplement to the owner’s manual also tells buyers not to worry if they hear the car’s turbo coolant pump running for a long period of time after the vehicle has shut off. During normal operation, the area around the turbos can get extremely hot and potentially cause damage to the car if these high temperatures aren’t dissipated. As such, the turbocharger’s cooling system—which runs on a separate loop to the engine cooling system—may be active for as long as twenty minutes after the motor stops running. Capacities for both cooling systems are also listed, as is oil volume. 

The output for this new engine in the upscale Grand Wagoneer or the normal Wagoneer has not yet been stated, but it’s probably safe to assume that the Grand Wagoneer will get the high output version with more than 500 horsepower, and the regular Wagoneer will get the low output version, with around 400. Exact power figures have not been disclosed yet, though.

Until formal announcements are made, we won’t know for sure. We’ll just have to wait for Chrysler, Jeep, Dodge, and Ram to reveal what their own particular flavor of this new engine is capable of.
