The 2026 Jeep Grand Cherokee L is the three-row version of the popular Jeep Grand Cherokee, built for families and drivers who need a real third row without giving up the Grand Cherokee's trail manners. Fold both rear rows flat and it opens up to 84.6 cubic feet of cargo space, enough to handle a furniture run or a week of family luggage. With all three rows upright it still holds 17.2 cubic feet behind the back seats, and it seats up to seven passengers across configurations that adapt from school pickup to a weekend road trip.
This page is your full breakdown of the Grand Cherokee L's cargo space, interior dimensions, and seating flexibility. At Jeep Portsmouth, we help Seacoast families from Dover and across the region figure out whether the longer L is the right call, or whether the two-row Grand Cherokee fits their life better. For engines, towing, and trim pricing, follow the in-text links to the spokes that cover those in depth.
Cargo space in the Grand Cherokee L scales with how many seats you are using, and it covers three useful configurations. Behind the third row you have 17.2 cubic feet, which is plenty for several grocery bags, a couple of gear bags, or a stroller and a cooler. Fold the third-row bench down and that grows to 46.9 cubic feet, opening room for luggage, hockey bags, or camping gear while five people still ride comfortably. Drop both the second and third rows and you reach the full 84.6 cubic feet, which is in minivan territory and handles a flat-screen box, small furniture, or a full weekend's worth of family equipment.
The load floor is flat once the seats are folded, so long items slide in cleanly from the tailgate, and the cargo opening is wide. One honest note for shoppers cross-shopping the class: the Grand Cherokee L's load floor sits fairly high, and its maximum volume trails roomier rivals like the Volkswagen Atlas, so if raw cubic feet is your main priority, compare it directly. If you want a third row plus genuine Jeep capability in one vehicle, the L delivers a balance many three-row crossovers cannot. Drivers who do not need seven seats should weigh the two-row Grand Cherokee's cargo space, which tops out at 70.8 cubic feet in a shorter, easier-to-park body.
Up front, the Grand Cherokee L gives drivers and passengers 41.3 inches of legroom, 39.8 inches of headroom, and 59.2 inches of shoulder room, so tall adults settle in without compromise. The second row is where the extended wheelbase pays off: Jeep cites best-in-class second-row legroom, and the measured 39.4 inches keeps adults comfortable on a long highway pull toward the Lakes Region. Headroom stays generous at roughly 39.9 inches even with the available panoramic sunroof.
The third row is a genuine seating area rather than an afterthought. The L stretches about ten inches longer than the two-row Grand Cherokee, and that length goes straight into passenger space. In independent testing, Edmunds found comfortable room for passengers up to six feet tall in both the second and third rows for shorter trips, with younger kids fitting fine for any distance. Getting back there is easy because the second row tilts and slides forward.
The Grand Cherokee L offers up to seven-passenger seating with the available second-row bench, or a six-passenger layout when you choose second-row captain's chairs for easier walk-through access to the back. On higher trims, the second- and third-row seats can power-fold from buttons in the cargo area or through the Uconnect touchscreen, which is a real convenience when your hands are full at the curb. Lower trims use manual latches and pull straps that tilt and slide the seats.
For growing families, the second row is wide enough to accommodate three child car seats across, and the seats fold close to flat for hauling. That mix of child-seat capacity, fold-flat cargo room, and quick third-row access is what makes the L work as both a people-mover and a gear-hauler in the same week. Seating and feature details vary by trim, so check the Grand Cherokee trim levels before you order.
A manual liftgate is standard, and a power liftgate comes standard on Limited and higher trims, with a hands-free function available. The flat load floor and wide opening make loading bulky boxes straightforward, and there is a spare tire mounted underneath rather than eating into the cargo hold. The shape of the space is as useful as the volume: a long, square cargo area is easier to pack tightly than a tall, narrow one.
The cabin is set up for a full load of people. Three-zone automatic climate control is standard, and available Quad-Zone Automatic Temperature Control lets the second row set its own temperature. The L was engineered with extra passengers in mind, offering six USB ports with a USB-A and a USB-C in each of the three rows, so no one runs out of charge on the way to a travel-team weekend. The available FamCAM interior camera shows a live feed of the second and third rows on the touchscreen, so the driver can check on kids or pets without turning around. Available Amazon Fire TV lets rear passengers stream over the vehicle's Wi-Fi, and heated rear seats are available to keep everyone comfortable through a New Hampshire winter.
The Grand Cherokee L earns its size in everyday Seacoast use. UNH move-in weekend in Durham is exactly the kind of job the 84.6-cubic-foot cargo hold was built for, and the third row means you can still bring the whole family along for the drop-off. For weekend trips up to Lake Winnipesaukee, you can seat seven with the bench or fold the third row for 46.9 cubic feet of gear while five ride in comfort. Around town, Dover and Rochester commuters get a vehicle that carries car seats during the week and a trailer on the weekend, and Sanford, Maine drivers get genuine Jeep all-weather footing.
