2026 Jeep Grand Wagoneer L Summit Obsidian: Texas-Sized Luxury That Pulls Like a V8
A couple of years ago at the Detroit Auto Show, I climbed into the third row of every three-row vehicle on the show floor. Even then, the Jeep Grand Wagoneer L was one of my favorites. Earlier this year, my family spent a week in a regular-length, lower-trim 2026 Jeep Grand Wagoneer during a family wedding in New York. Now that we’re back home in Texas, Jeep handed us the keys to something even bigger: the Texas-sized 2026 Jeep Grand Wagoneer L Summit Obsidian.
First, a huge thank you to Jeep for loaning us this $106,890 luxury SUV. We put more than 1,000 miles on it, including a run three hours west to the other side of Dallas, and it has a lot to offer in space, power, and luxury touches. It also has a few quirks worth knowing about before you sign on the dotted line.
Hurricane Power Replaces the Hemi V8
Yes, the V8 is gone from Jeep’s biggest SUV. We saw that change coming back when the Grand Wagoneer L first arrived. In its place is a 3.0-liter twin-turbocharged Hurricane inline-six that makes 420 horsepower and 468 lb-ft of torque, paired with an eight-speed automatic transmission.
I have loved this powertrain. It doesn’t sound like a V8, but it definitely pulls like one. Between the Hurricane and the smooth transmission, you never feel like you’re driving something as big as this Jeep really is. My only real gripe is that it’s thirsty. The EPA rates the Grand Wagoneer L at 16 MPG city, 22 MPG highway, and 18 MPG combined. Still, we averaged 18.9 MPG over our week, even with some idling while filming.
Stop/start is also standard, and you turn it off with one of the haptic buttons on the dash rather than a physical switch.
Jeep Is Back on the Hood
When the Grand Wagoneer launched, Wagoneer was its own sub-brand, and you could hardly find a Jeep logo anywhere on it. However, that changed with the 2026 facelift. There’s now a prominent Jeep logo on the hood and another on the liftgate.
Up front, sequential turn signals frame an illuminated seven-slot grille. That upper grille is mostly for show, but the real grille sits low, along with running lights that mimic fog lights, though they don’t really light the road ahead. Overall, it’s a clean, evolutionary look that keeps the Grand Wagoneer fresh against its main rivals.
22-Inch Wheels and Gloss Black Everything
Our wheels are just like the rest of this vehicle: huge. Specifically, the Summit Obsidian rides on dark 22-inch wheels with an elegant design, wrapped in 285/45R22 Pirelli Scorpion Verde all-season tires that served us well over our 1,000-plus miles.
The Obsidian treatment continues with gloss black wheel arches, gloss black lower cladding (which is actually a power running board), and gloss black on the door handles, mirror caps, and roof. As a result, it all accentuates the big, boxy profile. Even the window trim is black instead of chrome, which I much prefer.
That L stands for long, and it is long. The Grand Wagoneer L takes on the Cadillac Escalade ESV and the Lincoln Navigator L. For example, think of GM’s longer Suburban-based SUVs versus its shorter Tahoe-based ones. The standard Grand Wagoneer we drove in New York is the shorter version.
Cargo Space That Would Have Saved Our New York Trip
Unlike some of its competition, you can’t open just the rear glass, but the power liftgate opens at the push of a button to reveal an insane amount of cargo space. There are 42.6 cubic feet behind the third row and 116.7 cubic feet with both rear rows folded. In Manhattan, we were hauling Holli’s side of the family and more than a week’s worth of luggage for everyone. Needless to say, the L would have made that trip so much nicer.
Buttons in the cargo area power fold the third row down and back up, but the second row can only be power released into the floor. That matches the Cadillac Escalade but falls short of the Lincoln Navigator’s full power second-row seats.
With the liftgate all the way up, I just fit underneath at 5-foot-10. If that’s too high for you, raise it to the height you want, then press and hold the button on the side of the liftgate. After that, it will stop there every time. A trailer hitch hides behind a cover out back, and the Grand Wagoneer L can tow up to 9,860 pounds with the Heavy-Duty Trailer-Tow Package.
Power Running Boards and a Flag That Flies Both Ways
The Grand Wagoneer L uses a proximity key with passive entry on all four doors. As you walk up, it knows you’re close, and the power running boards deploy for you. Walk far enough away and they retract, then they deploy again when you open a door. In addition, you can deploy them manually from the touchscreen, which is a nice touch on a vehicle this tall.
Before you open the door, look for the nod to Jeep’s military history. For instance, an American flag on each side looks like it’s on a flagpole, waving in the wind. The passenger-side flag is reversed, so both look like they’re flying as you drive.
A Black-on-Black Cabin With Massaging Seats
Inside, the Obsidian name means everything is black. There’s plenty of leather and a mix of materials, so it isn’t just a sea of the same black. The seat controls have moved to the door, along with gloss black, illuminated haptic controls for the massage, its intensity, and the two-person memory. However, those haptic controls are very easy to press by accident.
The front seats are 20-way power adjustable with power thigh support, so you long-legged folks have something to go on. They’re heated, ventilated, and massaging, and the physical buttons for heat and ventilation offer three stages. I can pick the back, the bottom, or both, which I really like. At the end of September here in Texas, those ventilated seats kept me from sweating my tail off.
Additionally, all four windows have auto up and down, the door pockets offer two tiers of storage, and a wrapped, rounded A-pillar handle helps you climb in.
Screens Everywhere, Plus One Rattle
Screens are everywhere in this Jeep. There’s a 12.0-inch Uconnect 5 touchscreen in the center, a dedicated passenger screen, a 12-inch digital gauge cluster, and a digital rearview mirror. The gauges are digital takes on analog dials, and I like them well enough, but I mostly relied on the head-up display. It’s absolutely massive and also shows turn-by-turn directions.
Below the main screen sits a power-retracting comfort screen with controls for the massaging seats and climate, front and rear. Raise it, and you’ll find USB-C ports, a Qi wireless charger, and an HDMI port for the passenger screen. That said, the vehicle has to be on to open or close it, and I like its Apple-like animation. I did track down a rattle, though. In fact, it isn’t the screen but the area just below it. When the center console wiggles, I get a little chirp.
Thankfully, there’s plenty of physical redundancy for all the digital controls. Climate has its own buttons, and over my left knee there’s a physical headlight control. Somebody tell General Motors.
The touchscreen also handles the 360-degree cameras, blind-spot cameras, ambient lighting, and power-folding third-row headrests for a better view out back. The FamCam works much like the one in the Chrysler Pacifica we spent so much time in. For example, tap any of the six seating positions to zoom in. Its spot behind the panoramic roof even lets you see the face of a child in a rear-facing car seat in the second row.
The Trouble With Gloss Black
I don’t like all the gloss black inside. For anyone who wonders why we complain so much about it, dust is why. After a week, the dust was already obvious. As a result, you’ll have to wipe it constantly to keep it looking clean, something other materials hide easily.
The metallic rotary gear selector is something Jeep is very proud of. In fact, one of the first media events I ever attended featured the pre-production Grand Wagoneer concept, back when it wasn’t a Jeep at all. Just know, however, that the dial gets hot to the touch in certain situations, and it’s as reflective as the gloss black around it.
Nearby are drive modes including Auto, Sport, Snow, Sand, and Rock. We left it in Auto. You’ll also find controls for the adjustable ride height and 4Lo, while the drive modes handle the rest.
A textured panel covers two cupholders and a phone slot. There’s also a felt-lined storage spot up top, a larger cubby down low, and a small, damped, felt-lined glove box. There’s no storage on either side of the center console, something the competition increasingly offers. Overhead, you get three HomeLink buttons and controls for the tri-pane panoramic sunroof, which brings plenty of light into an otherwise very dark interior.
Second-Row Captain’s Chairs and Rear Entertainment
The rear doors also have passive entry and open to built-in sunshades and the same rich materials as up front. Once again, door storage is two tiers, so there’s no extra pocket like a lot of the competition offers.
Our tester had the Rear-Seat Entertainment Group, with Amazon Fire TV on dual 10.1-inch screens. Thanks to the built-in Wi-Fi hotspot, you can stream Netflix, YouTube, Prime Video, and more. There are also HDMI and power ports, a headphone jack, and remotes stored in the center console.
The leather-wrapped captain’s chairs are heated and ventilated. Rear climate controls sit on the back of the center console, with vents there and on the B-pillars, but there are no ceiling-mounted air vents. You also get seatback pockets, more cupholders with a phone slot, and plenty of power outlets. The armrests retract but don’t ratchet, so they’re either up or down.
The Jeep Grand Wagoneer L Still Has One of My Favorite Third Rows
Back at the Detroit Auto Show, the Grand Wagoneer L’s third row stood out to me first because of how the second-row seat folds up and out of the way. The entertainment screens complicate it a little, but the seat holds its shape, so a car seat can stay installed in the second row while someone climbs into the way back.
Once you’re back there, the legroom is massive, even with the second row all the way back. It’s also wide enough for three adults. At 5-foot-10, my knees were nowhere near my chin, and I had plenty of headroom. The middle seat sits a little higher and firmer, but there’s still headroom there too.
Third-row passengers get power recline, USB-A and USB-C ports, their own air vents, padded armrests with cupholders, and little storage cubbies in front of the wheel wells. In addition, big windows and the third panel of the panoramic roof keep it from feeling like a cave. The middle seat belt retracts into the ceiling, so you get a wide, open space when the seats are folded, and power buttons back there move the second row out of the way so you can get out.
This is absolutely a vehicle you can pack full of adults with plenty of room for luggage behind them. In hindsight, we really should have asked for the L in New York.
Air Suspension Tames the 22-Inch Wheels
Out on the road, the Grand Wagoneer L drives very well. For example, on my trip west past Dallas, its Quadra-Lift air suspension and long wheelbase just cruised over everything. I don’t want to say I was piloting the Titanic, so I’ll say a large cruise ship, because anyone riding with me rode in style.
Usually, bigger wheels mean less tire sidewall and a rougher ride, because there’s less cushion and the suspension has to do all the work. However, the suspension does that work quite well here. In neighborhoods, I could roll through a series of dips without worrying about much of anything.
Visibility is also a favorite. Big windows, big convex mirrors, the head-up display, and a quick-access button for the 360-degree cameras make it easier to place something this long. The rearview camera mirror helps too, because there’s a lot of vehicle behind you before you reach that rear window.
Holli had a rougher introduction, getting behind the wheel for the first time in an unfamiliar place in this massive SUV. Her family review is coming soon to GT: Garage Talk, so stay tuned for her full take.

Final Thoughts on the 2026 Jeep Grand Wagoneer L Summit Obsidian
The 2026 Jeep Grand Wagoneer L Summit Obsidian is a big, comfortable, and powerful way to move a family and all of its stuff. In short, the Hurricane inline-six pulls like a V8, the air suspension masks those 22-inch wheels, and the third row is still one of the best I’ve sat in.
That said, it isn’t perfect. The Hurricane is thirsty, the gloss black collects dust in a hurry, the haptic seat controls are easy to bump, and our tester had a chirp from the center console. Still, at $106,890 as tested, it holds its own against the Cadillac Escalade ESV and Lincoln Navigator L. After a week in the standard Grand Wagoneer in New York and a week in the L here in Texas, I know which one I’d pick for our next family road trip.
