Discontinued in 1991, after almost 30 years in production, the iconic Jeep Grand Wagoneer has been rumored to return since the late 1990s. Chrysler first confirmed the nameplate in 2011, stating that it would go into production in 2013, but the Grand Wagoneer was postponed to 2015 and to 2018.

The SUV returned into the spotlight in 2019 when spy shots revealed a full-size Jeep built on a Ram 1500 truck frame and Jeep eventually confirmed the nameplate for a 2020 revival. The SUV is scheduled to debut on September 3 and even though Jeep is still mum on details, we already known a few things about the full-size hauler.

It will be inspired by the original Jeep Wagoneer

It features a boxy design, like the old Commander did, but with a more imposing stance that will enable it to compete against big haulers like the Cadillac Escalade. Jeep's teaser shots show big "Wagoneer" badges on the nose and the front fenders, just like the original SUV had.

The only Wagoneer-specific feature that we haven't seen yet is the wood trim that runs across the side panels. This is no longer a common design feature and we might not see it on the modern SUV, but Jeep could offer a special option or build a limited-edition version with this cool vintage element.

It will feature the iconic seven-slot grille

We've seen it in one of Jeep's teaser photos of the SUV, so there's no denying that the Wagoneer, like every other vehicle in the company's current lineup, will come with a seven-slot grille. Each slot will have additional seven vertical vents, which should result in a unique and more upscale look within the lineup. The modern Wagoneer will be the first of its kind to feature a seven-slot grille, as Jeep did not use such a design feature back in the day. The 1993 Grand Wagoneer that was based on the Cherokee came close with an eight-slot grille, though.

It will be Jeep's first seven-seat SUV since the Commander

The new Grand Wagoneer will bring seven-seat Jeeps into showrooms after 10 years.

It's worth noting that this statement is available for the U.S. market only. In China, Jeep is producing a Cherokee-based Grand Commander midsize SUV that offers seating for seven people, but it's not sold outside the Asian country. The Grand Wagoneer will also be the company's first full-size vehicle since the Commander was discontinued in 2010.

It will share underpinnings with the Ram 1500 truck

Unlike its predecessor, the Grand Wagoneer won't be based on an existing Jeep SUV. Instead, it will share underpinnings with the latest Ram 1500 truck, so it will be a body-on-frame design.

This will be similar to its historical predecessor, as the original Wagoneer was also based on a truck, namely the Jeep Gladiator. Of course, Jeep will modify the Ram 1500's platform in order to provide the comfort needed in an SUV. However, the Grand Wagoneer will also be off-road capable, so the platform will feature a high degree of modified and bespoke parts.

The Wagoneer will feature V-6 and V-8 power

Since it will utilize underpinnings from the Ram 1500, the Grand Wagoneer will also feature engine and transmissions offered in the pickup truck.

The mill generates 305 horsepower and 269 pound-feet of torque, while the mild hybrid system improves fuel economy and increases towing capacity.

Also equipped with the eTorque mild hybrid system - it produces 395 horsepower and 410 pound-feet of twist.

The 3.0-liter V-6 EcoDiesel could also be an option for the SUV. Ram introduced a new version of the EcoDiesel for the 2020 model year, rated at 260 horsepower and 480 pound-feet of twist. This mill is already available in the Jeep Gladiator and the Wrangler.

All engines will mate to ZF eight-speed automatic transmissions and will be available with rear- or all-wheel drive.

A more powerful variant isn't very likely, despite the fact that the Ram 1500 is available in TRX trim with the supercharged, 6.2-liter Hemi V-8 from Dodge's Hellcat models and the Jeep Grand Cherokee Trackhawk. This engine generates 702 horsepower and 650 pound-feet in the Ram 1500 TRX.

It will be the most luxurious Jeep ever

The original Jeep Wagoneer is credited for having started the premium SUV niche. It arrived years before Land Rover launched the premium Range Rover division and offered features that were unheard of on utility vehicles from the very beginning. Despite having become dated in some aspects in the 1980s, the Grand Wagoneer kept offering more and more comfort and luxury features, to the point it actually rivalled established players in this market.

It will also feature FCA's best technology available and the big infotainment display that's optional in most Jeeps will probably be standard in the Grand Wagoneer.

Will Jeep offer two different models?

The big question about the full-size SUV is whether it will be offered in one versions or two. While some rumors claim it will be called the Grand Wagoneer, others suggest that Jeep will launch two versions, the Wagoneer and the Grand Wagoneer. While the latter is a possibility, we don't yet know what the Grand model will be about. One possibility is that the Grand Wagoneer will be a more luxurious model, while the simple Wagoneer will be a bit more affordable, but still oriented toward premium buyers.

The other scenario is that the Grand Wagoneer will be a bit longer than the regular Wagoneer, thus offering more legroom in the second and third rows, as well as more trunk space. Something similar to what Chevrolet does with the Tahoe and Suburban.

How much will it cost?

Jeeps are relatively affordable with base stickers ranging from $22,620 for the Renegade to $34,000 for the Grand Cherokee.

If Jeep offers two models, the Wagoneer could come in at around $45,000, while the Grand Wagoneer could fetch about $55,000 before options. A fully loaded Grand Wagoneer will probably cost in excess of $70,000.

When will it be unveiled?

The new Jeep Grand Wagoneer will be unveiled on Thursday, September 3. In the absence of auto shows due to the coronavirus pandemic, the premium SUV will break cover online. Jeep will release the most important details about the new Grand Wagoneer and we'll be here to report everything about it.

When will it arrive in dealerships?

The new Grand Wagoneer will arrive in dealerships in 2021. The SUV will go on sale in the fourth quarter of 2020, but first deliveries won't commence until the second quarter of 2021. The Grand Wagoneer will debut as a 2022 model year vehicle.
