The full-size luxury SUV battlefield is heating up, and Jeep is charging in with a comprehensively updated contender for the 2026 model year. The iconic Grand Wagoneer, initially positioned as a premium alternative to the Cadillac Escalade and Lincoln Navigator, receives its most significant refresh since its reintroduction nearly five years ago. This isn’t just a simple facelift; for 2026, the Grand Wagoneer debuts with sharp new styling, a simplified model lineup, and, most importantly, a revolutionary new electrified powertrain that could change the game.

Having seen the vehicle in person, we can confirm that the 2026 Grand Wagoneer is a compelling mix of classic American presence and forward-thinking technology. Here’s everything you need to know about Jeep’s newest flagship.

A Revolutionary New Powertrain: The Grand Wagoneer REEF

While the sheet metal changes are significant, the headline story for 2026 is under the hood. Jeep is introducing a brand-new powertrain option called the Grand Wagoneer REEF, which stands for Range Extending Electric Vehicle.

This is not a conventional plug-in hybrid. The REEF model is better described as an electric vehicle with a gas-powered generator. Here’s the breakdown:

REEF Powertrain Details

• Powertrain Components: It combines a large 92 kWh battery pack with a 3.6L Pentastar V6 that functions solely as a range extender. The V6 is not connected to the wheels; it only generates electricity to recharge the battery.
• Performance: This sophisticated setup is good for a combined 647 horsepower and 620 lb-ft of torque, sent to all four wheels through a single-speed transmission.
• Range and Efficiency: Jeep estimates a pure-electric range of 150 miles on a full charge. When paired with the 20-gallon fuel tank of the V6, the total driving range is expected to exceed 500 miles.
• Acceleration: Despite its substantial weight, this powertrain should propel the Grand Wagoneer REEF from 0 to 60 mph in approximately 5 seconds.

This model is a direct answer to range anxiety, offering the zero-emissions benefits of an EV for daily commutes with the cross-country freedom of a gas-powered vehicle.

The Familiar Hurricane Engine

For those not ready to make the electrified leap, the base powertrain remains the proven 3.0L Hurricane twin-turbo inline-6. At launch, Jeep will offer it in the Standard Output form, which produces a robust 420 horsepower and 468 lb-ft of torque. This engine is paired with an 8-speed automatic transmission and a full-time four-wheel-drive system.

Notably, the more powerful High-Output Hurricane engine (540 horsepower) will not be available at launch, with Jeep likely focusing attention on the new REEF model. However, its return in future model years remains a possibility.

Exterior Styling: A More Integrated and Confident Look

The 2026 Grand Wagoneer sports a redesigned exterior that aligns it more closely with the broader Jeep family while enhancing its luxury appeal.

• Front Fascia: The front end incorporates design cues first seen on the Wagoneer S. The iconic seven-slot grille is now illuminated and has been moved slightly upward. It’s flanked by new LED headlights with a distinctive T-shaped accent light integrated into the lower bumper.
• Jeep Branding: In a significant shift, Jeep has added prominent Jeep badges to the hood and tailgate. This move away from treating Wagoneer as a separate sub-brand addresses previous consumer confusion and strengthens its family ties.
• Trim Levels Simplified: Jeep has eliminated the standalone “Wagoneer” model. All variants are now called “Grand Wagoneer,” with trims ranging from a base model to the off-road oriented Upland and the top-tier luxury Summit Reserve.
• Wheels and Stance: The Upland trim features a more off-road-ready look with a unique front fascia, skid plates, all-terrain tires on 20-inch wheels, and a specially tuned air suspension. The Summit Reserve, in contrast, rolls on luxurious 22-inch wheels.
• Size and Presence: The standard-wheelbase model is a substantial vehicle, measuring around 215 inches long with a 123-inch wheelbase. For those needing maximum space, the Grand Wagoneer L extends the overall length by another foot, offering best-in-class third-row legroom and cargo space.

Interior: Spacious, Luxurious, and Slightly Updated

Step inside, and you’ll find an interior that remains largely familiar, which is a good thing given its high-quality materials and exceptional space.

• Dashboard and Screens: The lower trims, like the Upland, feature a simplified layout with two primary screens: a 12.3-inch digital instrument cluster and a 12.3-inch central infotainment display running Uconnect 5. The higher Summit Reserve trims add two more 10.3-inch screens—one for the front passenger and one for climate/physical controls.
• Seating and Comfort: The Grand Wagoneer continues to be offered in 7- or 8-passenger configurations. The second row offers a massive ~40 inches of legroom and can be optioned with heated, ventilated, and even massaging seats. The third row is genuinely adult-friendly, with ~36 inches of legroom, power-recline functionality, and available heating.
• Cargo and Utility: With the third row up, cargo space is a best-in-class 27.5 cubic feet. Folding it down expands capacity to over 70 cubic feet. The available L model boosts third-row cargo space to a cavernous 42 cubic feet.
• Premium Features: Top trims can be equipped with a 23-speaker McIntosh audio system, a refrigerated console, a panoramic sunroof, and a digital rearview mirror.
