Jeep® Drops More Details on the Upcoming Grand Wagoneer REEV

Jeep® is preparing to enter uncharted territory with the 2026 Grand Wagoneer REEV, the brand’s first range-extended electric vehicle. Following a recent deep dive with Jeep’s design and engineering teams, more details have surfaced about what could become one of the most innovative large SUVs on the market. The REEV—short for Range-Extended Electric Vehicle—promises luxury, performance, and freedom from range anxiety in a way that blends Jeep’s off-road heritage with next-generation technology.

A New Era for Jeep’s Flagship –

For 2026, Jeep is simplifying and strengthening its premium lineup. The Grand Wagoneer will now serve as the sole flagship, absorbing the Wagoneer nameplate into a unified model range. That means every Grand Wagoneer now proudly wears the Jeep badge, a move designed to create a clearer identity and reflect the brand’s American roots.

According to Jeep® CEO Bob Broderdorf, the change aligns with the company’s goal of creating a more cohesive and straightforward lineup. “This is about clarity for customers and dealers,” he explained, emphasizing that the Grand Wagoneer represents the pinnacle of the Jeep brand—luxury, craftsmanship, and legendary capability all in one.

America’s First Range-Extended Electric SUV –

The big news is, of course, the debut of the Grand Wagoneer REEV—America’s first large SUV to use a range-extended electric setup. It combines a massive liquid-cooled 92-kWh battery pack with a 3.6-liter Pentastar V6 engine that acts solely as a generator. The engine doesn’t power the wheels directly—instead, it feeds a 130-kW generator, which produces electricity to charge the battery or maintain its charge while driving.

This setup allows the Grand Wagoneer REEV to run exclusively on electric motors, delivering smooth, instantaneous torque without the compromise of traditional hybrids. When the battery runs low, the gas engine seamlessly activates to generate power, ensuring there’s never a moment of range anxiety.

Micky Bly, Stellantis’ Senior VP of Global Propulsion Systems, summed it up best: “Our award-winning HURRICANE twin-turbo I6 delivers exceptional performance, but the REEV takes it even further. It gives customers quiet all-electric driving for daily use and the freedom to travel across the country without worrying about charging infrastructure.”

Electrified Power Meets Jeep Strength –

The Grand Wagoneer REEV packs serious muscle—an estimated 647 horsepower and 620 lb.-ft. of torque, making it the most powerful Grand Wagoneer ever built. That’s enough to send this massive luxury SUV from 0 to 60 mph in just five seconds flat.

Despite the added tech, it doesn’t compromise on practicality. Jeep estimates a total driving range of roughly 500 miles when the tank and battery are full. That’s less than the Ram 1500 REV’s 690-mile rating but still more than enough for family vacations or towing trips.

A key detail is the REEV’s 20-gallon fuel tank, which is slightly smaller than the one found in the Ram 1500 REV (27-gallon) due to packaging constraints related to the Grand Wagoneer’s rear HVAC system. Still, that smaller tank works seamlessly with the REEV’s efficient Atkinson-cycle Pentastar V6 generator to keep the battery charged and extend total range. It’s a carefully engineered balance between efficiency, packaging, and performance.

Jeep engineers designed the system with three operating modes:

• Charge Depleting (EV Mode):
  The 92-kWh battery powers the electric drive modules directly for all-electric driving. The engine and generator remain off, providing quiet, zero-emission performance.
  (Battery → Electric Drive Module → Wheels)

• Hybrid Mode (Low State of Charge):
  When the battery charge is low or under cold/hot conditions, the 3.6-liter Pentastar V6 starts to drive the onboard generator (GPIM). It converts fuel energy into electricity to power the motors and maintain the battery.
  (Fuel Tank → Engine → Generator + GPIM → Electric Drive Module → Wheels)

• Power Looping Mode:
  During heavy towing, steep climbs, or sustained demand, the engine and generator continuously supply power to the motors, ensuring smooth, consistent performance.
  (Fuel Tank → Engine → Generator + GPIM → Electric Drive Module → Wheels)

Design and Functionality –

Like its gasoline counterpart, the Grand Wagoneer REEV will be offered in both short-wheelbase and “L” long-wheelbase versions. Jeep engineers managed to package the battery system flat within the chassis, preserving interior space and maintaining a true three-row layout without compromise.

From the outside, the REEV looks every bit as premium as you’d expect—bold, upright, and unmistakably American. It’s expected to feature subtle design cues that distinguish it from the gasoline versions, possibly including unique badging and color accents.

However, don’t expect to see a “4xe” badge on the tailgate. Jeep is reportedly rethinking the 4xe branding altogether. Broderdorf explained that many customers associate “4xe” strictly with plug-in hybrids (PHEVs), not range-extended electrics or full EVs. “We’re evaluating how to better communicate what each technology represents,” he said. Interestingly, Jeep’s new Compass (J4U) BEV in Europe also wears a 4xe badge for now, but Broderdorf hinted that it may change as the brand updates its naming conventions.

A Smarter Path to Electrification –

Where traditional PHEVs rely on their engines to power the wheels directly, Jeep’s REEV system uses the engine only as a generator. This makes it a more elegant solution—drivers get the refinement of an electric vehicle with the convenience of a gasoline backup.

In practice, that means you could drive the Grand Wagoneer REEV every day without ever plugging it in, relying solely on gasoline to recharge the battery. Yet those who do charge it will enjoy pure electric driving for shorter trips, creating the perfect blend of performance and practicality.

Jeep believes this approach will resonate with American buyers who want to go electric but aren’t ready to commit fully to charging infrastructure. “The REEV gives you freedom,” Bly noted. “You can plug it in if you want to—or never plug it in at all.”

Built With Quality in Mind –

Broderdorf also highlighted Stellantis’ new approach to product launches under Stellantis CEO Antonio Filosa. Unlike the rushed rollouts seen in the past, Jeep is taking a slower, more deliberate path. “Launch dates don’t mean anything to me,” Broderdorf said. “What matters is getting it right the first time.”

The Grand Wagoneer REEV is expected to debut in the first half of 2026, but Jeep won’t release it until it’s confident in its quality. “Filosa is hardcore about getting things right,” Broderdorf added, signaling a renewed focus on long-term reliability.

The Road Ahead –

Jeep hasn’t announced the exact pricing or trim breakdown for the REEV yet, but it’s expected to follow the structure of current Grand Wagoneer models, with multiple luxury-focused trims. While we don’t yet know how customers will respond, Broderdorf believes this technology can make a real impact. “A REEV setup can do more damage in the electrified market than a plug-in hybrid,” he said confidently.

In other words, Jeep’s flagship SUV is not just evolving—it’s redefining what it means to be both powerful and practical in the modern world.
