2027 GMC Terrain Interior Dimensions, Cargo Space, and Cabin Technology
The 2027 GMC Terrain seats five passengers across two rows. Front occupants get 40.58 inches of headroom and 43.95 inches of legroom. Second-row passengers get 39.2 inches of headroom and 39.7 inches of legroom. Cargo volume measures 29.8 cubic feet behind the second row and expands to 63.5 cubic feet with the rear seatbacks folded flat.
How Much Passenger and Cargo Space Does the 2027 GMC Terrain Have?
Full interior measurements for the 2027 model year are listed by Edmunds for the 2027 Terrain.
| Interior Measurement | 2027 GMC Terrain |
|---|---|
| Seating Capacity | 5 passengers, two rows |
| Front Headroom | 40.58 in. |
| Rear Headroom | 39.20 in. |
| Front Legroom | 43.95 in. |
| Rear Legroom | 39.70 in. |
| Cargo Volume (Second Row Up) | 29.8 cu. ft. |
| Cargo Volume (Maximum) | 63.5 cu. ft. |
The cabin layout prioritizes passenger comfort in both rows within a compact exterior footprint. Front occupants benefit from generous shoulder space and expansive legroom, creating an open posture for highway driving. Second-row legroom comfortably accommodates adult riders or rear-facing child safety seats without pushing the front bucket seats forward.
That balance between passenger space and rear cargo capacity suits daily routines across North Texas. Whether commuting along Highway 287 or visiting the historic Ellis County Courthouse square in downtown Waxahachie, the interior volume accommodates full passenger loads alongside everyday cargo. The upright roofline preserves rear headroom throughout the back seat, so taller passengers sit comfortably without feeling cramped.
How Does Seating Configuration and Power Adjustment Work Across 2027 GMC Terrain Trims?
Front seat adjustment
Featuring front bucket seats and a 60/40 split-folding rear bench, the 2027 GMC Terrain accommodates five passengers. Front seat adjustment on the Elevation begins with six-way manual driver settings and a height-adjustable driver seat. An 8-way power driver seat is available on the Elevation through the Elevation Premium Package and comes standard on the AT4 and Denali.
Second-row flexibility
The 60/40 split rear bench folds virtually flat to accommodate longer items while keeping one or two seating positions available for passengers. When walking families through the vehicle on our showroom floor, our sales team often points out how easily a child seat stays installed on the single-seat section while the wider bench section drops flat to load gear.

Standard driver-assistance systems
Active safety equipment operates continuously to assist the driver across varying traffic conditions. These systems are standard on every trim:
Blind Zone Steering Assist
Monitors side blind spots and applies subtle steering corrections if a lane change is initiated toward an approaching vehicle.

Scans the road ahead to warn of potential front-end impacts or unsafe following distances.
Front Pedestrian and Bicyclist Braking

Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.

How Much Cargo Space and Practical Storage Does the 2027 GMC Terrain Offer?
The 2027 GMC Terrain offers 29.8 cubic feet of cargo space behind the second row, expanding to 63.5 cubic feet of maximum cargo volume when the rear seatbacks fold flat.

Storage features
Underfloor Storage
The rear cargo underfloor storage compartment provides hidden storage for emergency road kits, tools, or valuables, keeping the primary cargo area clear.
Center Console Passthrough
Up front, the center console passthrough creates open tray storage beneath the main gear selector for handbags, tablets, or charging cables.
AutoSense Power Liftgate
Available on the Elevation and standard on the AT4 and Denali, it opens hands-free when it detects the key fob as you walk up to the rear of the vehicle.
The cargo floor features flat load surfaces and durable side paneling that withstands heavy gear, eliminating the need to balance items while reaching for a handle. For drivers carrying outdoor equipment, sports bags, or camping gear around Midlothian and Ennis, the low floor height simplifies loading bulky items.
