New 2027 Jeep Grand Wagoneer L Dimensions, Interior, Review – The 2027 Jeep Grand Wagoneer L arrives with subtle yet impactful styling updates that emphasize its sheer size and upscale presence. As the extended-wheelbase version of Jeep’s flagship SUV, the “L” variant gets an additional 12 inches of overall length and an expanded wheelbase for more third-row space and cargo capacity.
For 2027, Jeep enhances the design with smoother body lines, a more aerodynamic front fascia, and a reshaped grille flanked by thinner, high-performance LED lighting. The illuminated seven-slot grille features active shutters for better airflow and efficiency, while a revised hood sculpt gives the front end a more premium silhouette.

Exterior & Interior
Step inside the 2027 Grand Wagoneer L and you’re met with an expansive, refined space that feels more like a private jet cabin than a traditional SUV. The extended length pays dividends, especially in third-row legroom and cargo space, which now exceeds 45 cubic feet even with all seats in use. Jeep has reconfigured the second and third rows for increased recline angles and easier access, while power-folding seats in all rows add an extra layer of convenience. Cabin materials remain first-class: quilted Palermo leather, genuine walnut and open-pore ash trim, and aluminum accents elevate the cabin.
Tech features are just as impressive. The center console now houses a 16-inch OLED touchscreen with the latest Uconnect 6 interface, boasting 5G connectivity, faster boot-up times, and split-screen functionality. A dedicated 10.25-inch passenger display offers co-pilots navigation and entertainment access. In the second row, passengers enjoy two large entertainment screens with Amazon Fire TV and independent HDMI input, while the McIntosh 23-speaker reference audio system delivers studio-level sound throughout. Optional features include a refrigerated console, digital rearview mirror, and a full-color heads-up display with turn-by-turn navigation. The Grand Wagoneer L sets a new bar for large SUV comfort and convenience.
From the side, extended rear doors improve entry to the third row, and revised window trim gives the Grand Wagoneer L a sleeker, more limo-like vibe. At the rear, the updated taillights now wrap around the body for a more sophisticated look, and the tailgate integrates a satin-brushed aluminum strip with the Wagoneer branding laser-etched beneath the glass. Larger 22- and 24-inch wheel options give the L even more road presence, and the refined suspension design means the massive SUV rides lower and cleaner without compromising ground clearance when needed.

New 2027 Jeep Grand Wagoneer L Specs
Engine & Performance
Under the hood, the 2027 Grand Wagoneer L is all about modern, muscular efficiency. The standard engine is Jeep’s high-output 3.0-liter twin-turbo Hurricane inline-six, producing 510 horsepower and 500 lb-ft of torque. This engine is mated to a newly calibrated 8-speed automatic transmission that delivers smooth, decisive shifts under both light cruising and full throttle. Even with its size, the Grand Wagoneer L can sprint from 0 to 60 mph in just over 5.5 seconds. Quadra-Drive II 4WD is standard, paired with an electronically controlled limited-slip rear differential, giving this luxury beast serious all-terrain ability.
For 2027, Jeep adds the Grand Wagoneer L 4xe to the lineup—a plug-in hybrid variant combining the same Hurricane engine with two electric motors and a 27-kWh battery. Total output lands around 475 horsepower and 470 lb-ft of torque, with an estimated all-electric driving range of 43 miles. Jeep’s new plug-in architecture allows DC fast charging, giving the 4xe variant an 80% recharge in just 25 minutes. With selectable EV modes, regenerative braking, and hybrid tuning optimized for towing and off-road scenarios, the Grand Wagoneer L 4xe becomes a smarter, cleaner choice without sacrificing strength.
New 2027 Jeep Grand Wagoneer L Fuel Economy
Despite its size, the 2027 Grand Wagoneer L delivers respectable fuel efficiency thanks to its lightweight architecture and the efficient Hurricane engine. The standard gas model achieves 17 mpg city and 23 mpg highway, an improvement over previous versions. The 4xe plug-in hybrid variant offers up to 70 MPGe and can cover most daily commutes on electric power alone. New aero enhancements, low-resistance tires, and a more efficient AWD system all contribute to better overall range and fewer emissions—without compromising performance or capability.
New 2027 Jeep Grand Wagoneer L Safety Features
The 2027 Jeep Grand Wagoneer L doesn’t cut corners on safety and driver assistance. All trims come standard with Jeep’s new Active Drive Assist 2.5, featuring hands-free highway driving on over 400,000 miles of mapped roads. It uses an advanced array of LiDAR sensors, radar, and high-resolution cameras to provide lane centering, predictive cruise control, and smart traffic jam assist. This system also supports automated lane changes, adaptive speed based on road conditions, and proactive blind spot avoidance. Jeep has also introduced Smart Trail Exit, a feature that guides the vehicle out of tight off-road paths using AI-enhanced mapping.
Beyond semi-autonomous features, traditional safety tech has been re-engineered for precision. Forward collision warning with pedestrian/cyclist detection, intersection assist, and evasive steering support all come standard. A surround-view camera system with real-time 3D rendering makes maneuvering the SUV effortless, while night vision assist with animal and human heat signature detection adds confidence during rural drives. Rear seat reminders, ultrasonic cabin exit sensors, and an upgraded crash avoidance system mean the Grand Wagoneer L is as safe as it is massive. New 2027 Jeep Grand Wagoneer L Dimensions
