CAUGHT: 2023 Jeep® Grand Wagoneer Long Wheelbase (LWB):

Get Ready Escalade ESV, Navigator L, & Yukon Denali XL...

With the launch of the 2022 Jeep® Wagoneer and Grand Wagoneer (WS), the American adventure brand extends its reach back into the ultra-premium luxury SUV segment and re-introduces the iconic nameplate back into the brand’s lineup. Now that customers have been taking their home the new Wagoneers, Jeep is gearing up for another variant of the Wagoneer with a longer wheelbase (LWB) model.

In order to compete with the likes of other premium full-size SUVs like the Cadillac Escalade, Lincoln Navigator, and GMC Yukon XL Denali, both the Wagoneer and Grand Wagoneer will offer an LWB version. The LWB models are scheduled for a 2023 model year introduction and will offer even more third-row room (a category that the WS already is already a leader in).

This recent series of spy photographs from KGP Photography show the size difference between the small-wheelbase (SWB) and LWB models. Design elements will be almost identical between the two models, with the only noticeable difference being the length in the rear window and that the rear door will not cut into the rear wheel opening, unlike the SWB model.

Under the hood, you can expect a trio of engines. The updated 5.7-liter HEMI V8 with eTorque should come standard on the Wagoneer. The 2022 Jeep Wagoneer was the first Stellantis vehicle to feature the next-generation eTorque system, which features several fuel-saving features. Those enhancements include…

  • E-motor Assist: The eTorque motor provides electric assist to the engine from launch until the battery pack reaches a minimal state of charge, with the duration determined by throttle input from the driver.
  • Deceleration fuel shutoff: The system completely shuts off fuel delivery to the engine while the Wagoneer coasts down from highway speeds and under braking, enhancing fuel economy.
  • No-delay start/stop: The Wagoneer anticipates rolling stops, shutting down the engine as soon as vehicle speed reaches 0 mph, enhancing fuel savings. Engine restart with the eTorque motor is seamless and instant, even in aggressive driving conditions. Wagoneer accessories are powered by the battery pack while the engine is stopped.

The 6.4-liter SRT HEMI V8 will also continue as the standard engine for the Grand Wagoneer. The 6.4-liter HEMI delivers 471 horsepower and 455 lb.-ft. of torque and is engineered to provide a broad torque band to deliver the optimal blend of power and comfort regardless of the load and terrain. The 6.4-liter V-8 enhances fuel economy with Fuel Saver Technology cylinder deactivation and variable camshaft timing.

All-new for 2023, will be the introduction of the turbocharged 3.0-liter inline-six-cylinder known internally as the “GME-T6”. The name GME-T6 is due to it being based on the Stellantis Global Medium Engine or (GME) family. The T6 part of the name stands for turbocharged six-cylinder. The engine had been under development from Fiat Chrysler Automobiles (FCA) engineers for a number of years. According to our sources, the project originally began with the idea of bringing a turbocharged V6 to market, before making its way to a more well-balanced I6 layout.

Our sources have informed us that there will eventually be three different variants of the GME-T6 finding their way under the hood of several new products in the company’s pipeline. The three variants include a standard output (S.O), an H.O., and a plug-in electric (PHEV).

The H.O. version will be the first variant available and should make its way in the all-new 2022 Jeep® Grand Wagoneer (WS) first, sometime mid-2022. It will also be available in PHEV form on the Grand Wagoneer as well, allowing the ultra-premium Jeep offering to have somewhere in the ballpark of 525 horsepower. The PHEV version is said to be similar to the system found on the Grand Cherokee and Wrangler Unlimited 4xe models.

We expect the towing capacity of the LWB Wagoneer and Grand Wagoneer to be slightly below their SWB counterparts. If you look at the competition, there are about a 200 to 400 lbs. towing capacity decrease in its LWB models. Currently, the 2022 Jeep Wagoneer has a towing capacity of 10,000 lbs. (4,536kg), with the Grand Wagoneer coming in slightly below with 9,850 lbs. (4,472 kg). Nevertheless, the LWB models of the WS should still maintain best-in-class ratings.

Will predict that we should see the LWB models of the Wagoneer and Grand Wagoneer arriving in dealer showrooms in the third quarter of 2022.
