Passenger volume in the 2027 Grand Wagoneer measures 182 cubic feet across three rows. Front occupants get 40.9 inches of legroom and up to 41.3 inches of headroom. The second row seats two on power tilt-and-slide captain's chairs with 42.7 inches of legroom, while third-row passengers get 36.6 inches. Ordering a 40/20/40 second-row bench raises capacity from seven to eight on every trim apart from the Summit Reserve. Legroom matches in both wheelbases, so choosing the Grand Wagoneer L adds cargo room.

All eight trims heat and ventilate the front seats and heat the steering wheel, a useful mix for humid St. Louis summers and icy winters. Massage for both front occupants comes with the 20-way power seats in the three Summit trims, which also split the climate into four zones. Other trims get 8-way power adjustment with 4-way power lumbar and three climate zones. Second-row heat is standard on Limited, Limited Altitude, Overland and all Summit trims, and Summit Reserve adds ventilation.

Every 2027 Grand Wagoneer driver faces a digital cluster and a 12.0-inch touchscreen that runs Uconnect 5 Nav with TomTom navigation. The cluster measures 10.25 inches on the Grand Wagoneer trim, Limited, Limited Altitude and Upland. Jeep fits the Overland and the three Summit trims with a bigger cluster, and their Augmented Head-Up Display presents driver-selected information on the windshield. Compatible phones connect without a cable through Apple CarPlay or Android Auto, then charge on the standard wireless pad.

Front passengers in a Summit Reserve get a 10.25-inch interactive display of their own. The available Rear-Seat Entertainment Group adds a 10.1-inch touchscreen to each front seatback, with Amazon Fire TV Built-In, for Limited, Limited Altitude, Overland and every Summit trim. Speaker counts climb from 9 on the Alpine system to 19 on the McIntosh MX950 and 23 on the Summit Reserve's McIntosh MX1375 Reference system. The MX950 is standard on Overland, Summit and Summit Obsidian, while Alpine serves the other four trims.

• SiriusXM 360L, trial subscription included
• McIntosh MX950 available on Limited and Limited Altitude

Three interior colors are offered on the 2027 Grand Wagoneer: Global Black, Sea Salt/Black and Tupelo/Black. Global Black is available on any trim. Sea Salt/Black covers seven trims, everything but the Summit Reserve. That trim offers Tupelo/Black instead, and no other trim gets it. So if Tupelo/Black is the goal, the trim decision is already made.

Leather grade follows the trim you choose. Capri leather and brushed metal-look accents dress the Grand Wagoneer trim and Upland, and Limited and Limited Altitude move to Nappa. Overland adds embossing to its leather-trimmed bucket seats and uses embossed metal accents. In the Summit and Summit Obsidian, Premium Nappa covers the seats, with Black Chiseled Metal accents in the latter. Summit Reserve brings Palermo leather, natural walnut wood accents and a suede headliner, and the available Obsidian Package swaps the walnut for Black Chiseled Metal.

• Global Black: available on all eight trims
• Sea Salt/Black: every trim except Summit Reserve
• Tupelo/Black: exclusive to Summit Reserve
• Nappa leather trim for Limited and Limited Altitude seats
• Summit Reserve: Palermo leather and a suede headliner
