The 2027 GMC Yukon delivers 122.8 cu ft of maximum cargo volume with up to 8-passenger seating across three rows. The Yukon XL extends that cargo advantage further with a longer wheelbase and additional third-row legroom. This page covers every interior dimension, row-by-row capacity, and trim difference.

The 2027 Yukon is built on a full-size SUV platform measuring 210.1 inches in overall length and 76.5 inches tall. Those numbers translate directly into a cabin that accommodates full-size adults in every row without compromise. The front row offers 44.5 inches of legroom, which is enough for drivers well over six feet tall to sit without adjusting the seat to its limits.
Cargo access is the Yukon’s clearest strength. Behind the third row, 25.5 cu ft of cargo space handles airport luggage runs and grocery loads without touching the passenger rows. Fold the third row and that figure jumps to 72.5 cu ft behind the second row, enough for furniture hauls, sports equipment, or stroller-plus-groceries combinations. With both rear rows folded, the Yukon opens to 122.8 cu ft of total cargo room.

The Yukon XL adds length over the standard model, pushing overall exterior length to approximately 225 inches. That extra length goes directly into third-row legroom and cargo depth behind the third row, making the XL the stronger pick for families who routinely use all three rows and still need cargo space.
The Yukon’s interior is organized around a configurable second and third row that gives owners real flexibility. The third row uses a standard power-folding split bench, so you can fold one side for a narrow cargo lane while leaving seating on the other. The second row in most trims is a bench seat configured for three passengers, bringing total capacity to 8. On trims offering available captain’s chairs, second-row seating drops to 2, reducing total capacity to 7 but opening a wide center walkthrough to the third row.
The 16.8-inch diagonal infotainment touchscreen sits high on the dashboard, which keeps the center stack compact and preserves knee clearance for front-row passengers. The 11-inch diagonal Driver Information Center gives the driver a clear secondary display without adding bulk to the dash.
The Surround Vision Recorder uses the HD Surround Vision cameras already mounted around the vehicle, so no additional hardware crowds the cabin. Footage saves to a USB drive in 2-hour loops, and security recording starts automatically when the alarm triggers for 30 seconds. That system is standard on the 2027 Yukon, not an add-on.
The core cabin dimensions stay consistent across the Elevation, AT4, Denali, AT4 Ultimate, and Denali Ultimate trims. What changes is how that space is finished and configured.
The Elevation uses heated leather-appointed front seats and heated second-row outboard seats. The cabin feel is upscale without the executive detailing of higher trims. Cargo dimensions are identical to the trims above it.
The AT4 changes the interior color palette to Forest Storm with Mahogany accents and switches to heated and ventilated front perforated leather seating surfaces. The off-road character carries through to brushed metal door sill plates with AT4 badging. Cabin volume is unchanged.
The Denali introduces the power-sliding center console, which physically expands usable center-row space when it shifts rearward. Heated and ventilated front perforated leather seats and heated second-row outboard perforated leather seats come standard. The 15-inch diagonal multicolor Head-Up Display projects navigation and speed data onto the windshield, reducing the visual gap between driver and forward road.
The AT4 Ultimate adds Air Ride Adaptive Suspension and 16-way power front seats with a massage feature. Its premium cabin builds on the AT4’s off-road-focused design while adding a higher level of seating comfort and interior refinement.
The Denali Ultimate adds 16-way power front seats with massage and available second-row executive seating. Those available second-row seats include heated and ventilated luxury captain’s chairs with massage, 14-way power adjusters, and stainless steel Bose head-restraint speakers built directly into the headrests. Those chairs reduce seating to 7 but make the second row a genuine premium experience rather than a pass-through.
The Denali Ultimate also steps up to an 18-speaker Bose sound system, compared to the 10-speaker Bose system on lower trims.
For families in Marion and across central Indiana, the practical question is whether the Yukon’s interior actually works on the routes and errands you run every week. The 25.5 cu ft behind the third row holds a week’s worth of groceries alongside a pair of travel bags, without asking anyone to give up their seat. The 72.5 cu ft behind the second row is enough for a 4×8 sheet of plywood laid flat if the third row folds out of the way.
The available rear-seat media system adds dual 12.6-inch diagonal color-touch LCD screens mounted to the back of the center console, each with Bluetooth headphone compatibility and an HDMI port. That system turns the second and third rows into a functional entertainment zone on long drives, reducing the demand on front passengers to manage audio for everyone.
Super Cruise hands-free driver assistance technology, available on the Denali, AT4 Ultimate, and Denali Ultimate, handles steering, acceleration, and braking on compatible roads. On highway miles between Marion and Indianapolis, that system shifts effort off the driver and reduces fatigue on longer family trips. Each of those trims includes a 3-year OnStar One plan alongside Super Cruise.
The Safety Alert Seat vibrates the driver’s seat instead of sounding an audible alert, which keeps cabin noise low in a full passenger load. Combined with standard Blind-Spot Alert, Lane Departure Warning, and Enhanced Automatic Emergency Braking, the Yukon’s safety system works in the background without demanding attention from anyone seated in the cabin.
The Yukon’s 122.8 cu ft of maximum cargo with both rows folded is competitive at the top of the full-size SUV segment. The Yukon XL’s longer body adds meaningful third-row legroom over the standard model, an advantage that shows clearly against shorter full-size competitors on that specific measurement.
The standard power-folding third row is a practical edge over full-size competitors that require manual folding. Families managing car seats, strollers, and gear do not want to wrestle a bench seat down by hand. The Yukon handles it electrically.
The available Duramax 3.0L Turbo-Diesel engine is an option not found across every competitor in the full-size segment. Buyers primarily concerned with per-mile operating cost on frequent highway runs have that engine as a verified option on the 2027 Yukon lineup.
The 2027 Yukon’s interior dimensions are best understood in person, with three rows of real passengers and your actual cargo alongside. Greg Hubler Buick GMC in Marion stocks Yukon and Yukon XL models across all five trims, so you can compare the Elevation’s cargo setup against the Denali Ultimate’s executive second row in the same visit. Bring the family, measure the legroom yourself, and drive it home the same day.
The 2027 Yukon offers 25.5 cu ft behind the third row, 72.5 cu ft behind the second row, and 122.8 cu ft of maximum cargo volume with both rear rows folded.
The Yukon XL measures approximately 225 inches in overall length versus 210.1 inches for the standard Yukon. That additional length provides more third-row legroom and more cargo space behind the third row.
The 2027 Yukon seats up to 8 passengers with the standard second-row bench seat. Trims with available second-row captain’s chairs seat 7.
Yes. The 2027 Yukon includes a standard power-folding split third-row bench seat, allowing one side to fold independently.
Super Cruise hands-free driver assistance technology is standard on the Denali, AT4 Ultimate, and Denali Ultimate trims. Each includes a 3-year OnStar One plan.
The Surround Vision Recorder is a standard feature that records video from the vehicle’s HD Surround Vision cameras to a USB drive in 2-hour loops. It also records automatically for 30 seconds when the vehicle alarm is triggered.
An available rear-seat media system adds dual 12.6-inch diagonal color-touch HD LCD screens with Bluetooth headphone compatibility and two HDMI ports on the back of the center console.
The 2027 GMC Yukon is assembled at GM’s Arlington Assembly plant in Arlington, Texas.
