Are the new Jeep Wagoneer and Grand Wagoneer not quite big enough for you? Well, you’re in luck as the automaker is preparing long-wheelbase variants of both models and was recently spied testing a camouflaged prototype. The new models will take on the likes of the Cadillac Escalade ESV, Lincoln Navigator L, Chevrolet Suburban, and GMC Yukon XL and based on these spy shots, look largely the same as the standard-wheelbase models.

The current 2022 Wagoneer and Grand Wagoneer are slightly longer than the standard wheelbase editions of GM’s trio of full-size SUVs at  5,453 mm long, 2,123 mm wide and 1,920 mm tall with a 3,124 mm wheelbase. By comparison, the Grand Wagoneer is 94 mm overall longer than the standard Cadillac Escalade (5,382 mm) with a 53 mm longer wheelbase (Cadillac: 3,071 mm). It’s almost certain that the LWB Wagoneer and Grand Wagoneer will top the Escalade ESV’s (3,406 mm) wheelbase.

 

Besides the elongated wheelbase of this prototype, you’ll notice that the rear overhang has also grown, as have the rear side windows. This will result in greater space offered to second- and third-row passengers while also boosting cargo capacity. Few other design changes are visible on this prototype due to the black and white camouflage wrap adorning the exterior but it certainly has a big presence on the road. It is also unclear if this prototype is a Wagoneer or the more luxurious Grand Wagoneer variant.

As for the powertrain options, we expect them to remain the same as the current Wagoneer and Grand Wagoneer that offer a 392-hp 5.7-liter HEMI V8 and a 471-hp 6.4-liter HEMI V8 respectively. It isn’t yet known when the new models will be launched but they will probably be sold as either 2023 or 2024 models.
