Jeep’s Wagoneer and Grand Wagoneer are full-size SUVs on trucks. This means that, like the Chevrolet Suburban and Lincoln Navigator, they share a chassis and powertrain with a half-ton pickup truck. But dismissing the Wagoneer as a new-body Ram does it a disservice: Jeep designed an arsenal of new technologies for the Wagoneer, including powertrain features not offered on any Ram truck.
The Grand Wagoneer has engines not yet available in a Ram truck

For the 2022 launch, Jeep’s Wagoneer and Grand Wagoneer offered two V8s. The regular Wagoneer came with the 5.7-liter HEMI V8 available in the half-ton Ram 1500. Dodge’s “Scat Pack” muscle cars.
But Jeep did something special with these engines: The automaker equipped the 6.4-liter HEMI with the eTorque mild-hybrid system that Ram developed for its half-ton trucks. This makes the Grand Wagoneer the only vehicle to offer a hybrid version of the 6.4-litre.
For the 2023 model year, Jeep expanded the engine line-up of the Wagoneer and Grand Wagoneer. It added the 3.0-liter turbocharged I6 that Stellantis developed worldwide for its full-size vehicles. The powerful new “Hurricane” engine uses 26 psi of boost to make over 500 horsepower and 500 lb-ft of torque – using just 3.0 liters. The Wagoneer SUVs are the first Stellantis vehicles to offer this new engine.

The Wagoneer and Grand Wagoneer have independent rear suspension

Early reviewers of the Wagoneer and Grand Wagoneer rave about the comfort, style and off-road capability. This full-size SUV won’t take on the Rubican course any time soon, but it feels surprisingly composed off-road given its size.
The Wagoneer SUVs owe some Ram technology to their off-road capabilities. They all ride on the rear coil springs that Ram designed for the fourth generation of its half-ton pickup truck and more recent Ram 2500 trucks. In addition, every Grand Wagoneer comes with the full-time 4WD Ram designed for its TRX supertruck. Finally, the Grand Wagoneer features the air suspension that is optional on Ram 1500 trucks.
Jeep also designed all-new technology for the Wagoneer. Instead of the rear axle of the Ram trucks, the Grand Wagoneer rides on independent rear suspension. This allows it to glide over off-road obstacles. At the same time, the Wagoneer maintains the highest towing capacity of any SUV.
The Wagoneer and Grand Wagoneer could be a preview of future Ram trucks

It is clear that Stellantis is throwing its most advanced technology at the luxurious Grand Wagoneer. For this reason, the full-size Jeep SUV could be a preview of the next generation of Ram trucks. Future Ram trucks will likely offer the I6 Hurricane engine. What’s more, Ram can move from its half-ton pickup to independent rear suspension for the sixth generation. We already have reason to believe that the upcoming Ram electric pickup will feature independent rear suspension.
Indeed, we see some of the more advanced technology from the Grand Wagoneer making their way into the 2023 Ram Truck. The new Ram 1500 Limited Elite Edition combines some of the luxury features of the Grand Wagoneer with a premium Ram truck.
