2027 Jeep Grand Wagoneer L Specs, Redesign, Dimensions – The 2027 Jeep Grand Wagoneer L enters the market with subtle but deliberate design and engineering improvements aimed at elevating luxury and capability. This extended-wheelbase SUV retains its body-on-frame foundation, yet it receives a reengineered platform with increased rigidity and reduced vibration.
The wheelbase has been marginally stretched for better third-row legroom and enhanced cargo space, while Jeep engineers have updated the suspension geometry to accommodate a smoother ride. The updated platform is supported by revised chassis mounts, retuned active dampers, and improved sound deadening layered throughout the underbody and firewall. 2027 Jeep Grand Wagoneer L Specs
2027 Jeep Grand Wagoneer L Redesign and Update Plan
Exterior & Interior
Visually, the 2027 Grand Wagoneer L is instantly distinguishable from its predecessor. The body features cleaner lines, more chrome delete options, and new color palettes like Gunmetal Pearl, Smoky Quartz, and Deep Redwood. The Obsidian trim returns with gloss black detailing, smoked exterior lighting, and black 22-inch wheels. Optional illuminated badging and a panoramic glass roof with night-sky projection transform the Wagoneer into a rolling luxury suite. Jeep also refines the air suspension ride heights, making entry and exit more seamless while keeping trail-rated capability intact.
Inside, the cabin of the Grand Wagoneer L is even more luxurious and tech-forward than before. Jeep now offers full-quilted Palermo leather with diamond stitching across all three rows. The dashboard has been redesigned with slimmer HVAC vents, new ambient lighting zones, and updated interface layouts. A 15-inch touchscreen runs the new Uconnect 6 system, supporting multi-screen functionality and OTA updates.
A new 10.25-inch touchscreen in the passenger dash lets occupants control audio, climate, and media independently. The digital gauge cluster grows to 12.3 inches with updated graphics and customization options. Rear-seat entertainment is upgraded with twin 12.6-inch 4K displays and full Amazon Fire TV integration. Interior wood trim includes genuine walnut and dark open-pore oak depending on the trim, and acoustic glass has been added to every window pane for superior cabin silence.
Design-wise, the 2027 Grand Wagoneer L looks more polished without losing its imposing character. Jeep reshapes the front fascia with a more refined seven-slot grille, thinner LED matrix headlights, and new DRLs that contour the headlamp housings. The front bumper integrates more aerodynamic corner elements, and the hood sits lower for improved forward visibility. At the rear, new taillights connected by a wide LED light bar give the SUV a stronger visual width. Available wheel sizes range from 20 to 24 inches, all wrapped in low-noise all-season tires. The redesigned side mirrors and roof rack have been optimized for better airflow, and Jeep adds power-retractable running boards to top trims for added convenience.

Engine & Performance
Under the hood, Jeep brings back the Hurricane twin-turbocharged 3.0-liter inline-six as standard equipment, delivering a robust 510 horsepower and 500 lb-ft of torque in the Grand Wagoneer L. Mated to a recalibrated 8-speed automatic transmission, this setup offers improved low-end torque and quicker shift logic thanks to a new electronic shift-by-wire system. Jeep eliminates the naturally aspirated V8 entirely for the 2027 model year in favor of the more efficient and powerful Hurricane architecture. All models feature standard four-wheel drive, with Jeep’s Quadra-Drive II system and an active rear limited-slip differential delivering optimal traction in any condition.
For those needing serious muscle, the high-output Hurricane engine option pushes power up to 575 horsepower, giving the Grand Wagoneer L one of the most potent powertrains in its class. Maximum towing capacity remains a class-leading 10,000 pounds, aided by a new trailer sway management system and digital trailer guidance with remote hitch alignment. Ride comfort is significantly improved with new active damping software, and Jeep has reengineered the brake system with larger rotors and more aggressive bite on initial pedal input. Whether cruising on the highway or crawling over rough terrain, the Grand Wagoneer L remains both commanding and refined. 2027 Jeep Grand Wagoneer L Specs
2027 Jeep Grand Wagoneer L Fuel Economy
Fuel economy figures show marked improvement thanks to the Hurricane engines and revised vehicle aerodynamics. The base Hurricane delivers an estimated 17 mpg city and 23 mpg highway, while the high-output version nets around 15 mpg city and 21 mpg highway. A plug-in hybrid (4xe) version is under development and is expected to launch in late 2027 with a projected 30+ miles of electric-only range and over 450 horsepower. This 4xe variant will use an electric motor integrated into the transmission and a 17-25 kWh battery pack under the rear floor, preserving cargo capacity.
2027 Jeep Grand Wagoneer L Safety Features
Safety tech sees a major overhaul in the 2027 Grand Wagoneer L. All models come with Jeep’s new Co-Pilot 2.0 suite, which includes adaptive cruise control with predictive stop-and-go, enhanced lane centering, and intersection assist.

Blind spot monitoring, rear cross-traffic alert, forward collision mitigation, and pedestrian/cyclist detection are now standard across the lineup.
Also included is Jeep’s Driver Attention Assist, which uses an infrared camera behind the steering wheel to detect fatigue or distraction, prompting alerts or even controlled slow-downs. The 2027 Grand Wagoneer L also offers ParkSense 360, a system combining perimeter sonar and visual overlays with automated parallel and perpendicular parking capabilities. Night Vision Assist returns with thermal imaging and extended pedestrian detection. Additional features include head-up display with turn-by-turn navigation, full-color augmented reality overlays, and digital rearview mirror with increased low-light sensitivity. 2027 Jeep Grand Wagoneer L Specs
