CAUGHT: 2023 Jeep® Wagoneer Series III LWB with Advanced All-Terrain Group!

Look Out Expedition Max FX4 & Yukon XL AT4...

Just a couple of days after we posted our first photos of the 2023 Jeep® Grand Wagoneer (WS) long-wheelbase (LWB) variant, we are now getting our first look at the Wagoneer LWB testing on public roads. The new LWB variants of the all-new Grand Wagoneer and Wagoneer, show us just how serious the Jeep brand is about competing against the other full-size premium SUV brands of Cadillac, Lincoln, and GMC.

This particular 2023 Jeep Wagoneer LWB tester appears to be the Series III with the Advanced All-Terrain Group, judging by the vehicle’s wheels and tires. The Wagoneer with the Advanced All-Terrain Group is the most off-road-oriented package available for the new Wagoneer nameplate. Unfortunately, unlike other Jeep SUVs, the Wagoneer is not “Trail Rated”.

In order to be a Trail Rated Jeep, the vehicle must pass five outlined criteria in order to place the Trail Rated medallion on its fender. The five criteria are traction, water fording, articulation, maneuverability, and ground clearance. The new Wagoneer models meet all of these criteria except one… maneuverability. Especially, with this new LWB model.

So what does the Wagoneer Series III Advanced All-Terrain Group include?

  • 20-inch x 9-inch Machined Cast Aluminum with Satin Granite Crystal-Painted Pockets
  • 275/55R20 Falken Wildpeak A/T All-Terrain Tires
  • Quadra-Drive II® Transfer Case with 4×4 Low Active, Neutral, Full-Time Active 4×4
  • Electronic Limited-Slip Rear Differential
  • Quadra-Lift Air Suspension
  • 3.92 Rear Axle Ratio
  • Selec-Speed® Control
  • Transfer Case Skid Plate
  • Fuel Tank Skid Plate
  • Front Suspension Skid Plate
  • Bright Tow Hooks
  • Removable Rear Tow Hook

The Wagoneer Series III with the Advanced All-Terrain Package is aimed squarely at offerings from Ford with its new Expedition FX4 Off-Road and the GMC’s off-road-oriented Yukon AT4. This new LWB version of the Wagoneer Series III is looking to steal sales away from those vehicles’ LWB variants in particular.

The current Wagoneer Series III also features things like a 10.1-inch Uconnect touchscreen, 19-speaker MX950 Entertainment System, a front passenger screen, tri-zone climate control, Nappa leather-trimmed seats, and Trailer Tow Group. We expect all of those features to carry over to this Wagoneer Series III LWB model.

To help power the Wagoneer Series III is the legendary 5.7-liter HEMI V8 with an eTorque mild-hybrid system. The 5.7-liter HEMI is good for 392 horsepower (292kW) and 404 lb.-ft. (548 Nm) of torque and is paired up with an 8HP75 8-speed automatic transmission.

The eTorque mild hybrid system replaces the traditional alternator on the engine with a belt-driven motor generator unit that performs several functions. The motor-generator unit works with a 48-volt battery pack to enable quick and seamless start/stop function, short-duration torque addition to the engine crankshaft in certain driving situations as well as brake energy regeneration, which improves responsiveness and efficiency.
 
With the engine running, eTorque’s motor generator unit feeds a 48-volt current to a 430 watt-hour lithium-ion Nickel Manganese Cobalt (NMC)-Graphite battery. In addition to spinning the engine for restarts, the eTorque unit also recaptures energy during deceleration and braking to feed charge to the battery pack.

There is also the all-new turbocharged 3.0-liter inline-six-cylinder engine (codenamed GME-T6). The GME-T6 will be offered in a number of Stellantis rear-wheel-drive (RWD) based vehicles including the next-generation Dodge Charger, Dodge Challenger, and Ram 1500, but will make its official debut in the Grand Wagoneer by the end of the year. We are still not sure yet if the GME-T6 will be exclusive to the Grand Wagoneer or available on the Wagoneer as well.

The GME-T6 will be offered in three variants when it hits the market, two of which will debut on the Grand Wagoneer. The High-Output (H.O.) version is said to be a performance upgrade for the Grand Wagoneer and will offer both fuel efficiency and performance to the ultra-premium SUV lineup.

Another version is a plug-in hybrid (PHEV), which should work very similar to systems we have seen on other Jeep products like Grand Cherokee and Wrangler Unlimited 4xe models. It is unclear if that too will be exclusive to the Grand Wagoneer or be passed down to the Wagoneer as well. It is believed that the PHEV version of the Grand Wagoneer could push over 500 horsepower to the Grand Wagoneer’s wheels.

Both the Grand Wagoneer and Wagoneer LWB models will be available sometime later this year, more likely in Q3 of 2022. Both models will be built alongside their SWB siblings at the Warren Truck Assembly Plant, in Warren, Michigan.
