The 2027 GMC Terrain in Denali AWD and AT4 AWD trims is the right compact SUV for East Tennessee families and commuters who want truck-inspired styling, standard all-wheel drive, and a genuinely modern cabin without stepping into a full-size price bracket. The AT4 AWD starts at $39,100 and the Denali AWD at $42,200 — both delivering 175 hp, 203 lb-ft of torque, 25 combined MPG, and about 30 cu ft of cargo space in a maneuverable 181-inch footprint.

How Well Does the 2027 GMC Terrain Denali AWD and AT4 AWD Serve Morristown and Surrounding Tennessee Drivers?
The 2027 GMC Terrain is purpose-built for exactly the kind of driving life that defines East Tennessee — a daily commute through rolling Ridge-and-Valley terrain, a weekend run to a state park, and enough cargo room for whatever the week throws at a family. Both the AT4 AWD and Denali AWD come standard with all-wheel drive, which matters on the moderately hilly roads that connect Morristown neighborhoods to healthcare campuses, manufacturing plants, and retail corridors across the region.
At 25 combined MPG — 24 city and 28 highway — the Terrain keeps fuel costs in check for households balancing a commute with family errands. The EPA-calculated range of 390 miles on a 15.6-gallon tank means fewer fill-ups across a workweek. For families hauling gear to Panther Creek State Park or loading up for a community festival, about 30 cu ft of cargo space behind the rear seats expands to about 63.5 cu ft with the rear bench folded — room enough for bikes, camping supplies, or a full load of groceries.
The Terrain also competes directly against the Chevrolet Equinox, Ford Escape, Honda CR-V, and Toyota RAV4 — a crowded class where GMC's truck family styling and premium trim differentiation give it a distinct identity. Shoppers looking for a new GMC SUV can browse our current GMC SUV inventory to see available configurations and colors in stock at Rusty Wallace GMC.
The two trims covered here serve different buyer priorities: the AT4 AWD leans into rugged capability with all-terrain tires and trail-ready character, while the Denali AWD delivers executive-tier luxury finishes and expanded technology. Both share the same powertrain, fuel economy, and safety suite — making the choice between them a matter of how you spend your weekends and what you want your daily driver to say about you.
​
Exterior Styling and Rugged Appeal of the 2027 GMC Terrain
The 2027 GMC Terrain wears its truck DNA visibly. At 181 inches long, 74.5 inches wide, and 66.2 inches tall on a 107.5-inch wheelbase, it carries the proportions of a purposeful compact SUV without tipping into the unwieldy size of a mid-size. The front fascia borrows cues directly from GMC's larger Sierra and Yukon lineup — a wide grille, squared-off body lines, and projector-beam LED headlights with LED daytime running lights that give it a recognizable face on any road.
MotorTrend noted the Terrain's "distinctive curb appeal, with handsome truck-ish sheetmetal," and that impression holds across both trims. The AT4 AWD distinguishes itself with body color-toned exterior mirrors and a trail-oriented character reinforced by its all-terrain tire fitment on 17-inch alloy wheels. The Denali AWD steps up to 19-inch two-tone alloy wheels with chrome mirror caps, chrome bumper accents, and the Denali badging that signals premium positioning at a glance.
Six exterior colors span the palette: Rapid Metallic, Summit White, Ebony Twilight Metallic, Riverstone Metallic, Volcanic Red Tintcoat, and Sterling Metallic. Two-tone roof options — Sterling Metallic Roof and Ebony Twilight Metallic Roof — are available on both trims for buyers who want added visual contrast. Painted front and rear bumpers are standard across both configurations, and chrome/silver roof rails come standard on both trims as well.
The AT4 AWD also offers an optional Panoramic Sunroof with one-touch electric operation and a sliding glass panel — a feature the Denali AWD shares as an option. Shoppers interested in a pre-owned Terrain can also explore our pre-owned GMC SUV listings for additional options. The overall silhouette — upright glasshouse, sculpted rear quarter panels, and a liftgate-style rear door — communicates both utility and refinement from every angle.
​
Performance and Towing Capabilities of the 2027 GMC Terrain Denali AWD and AT4 AWD's Terrain
Both the AT4 AWD and Denali AWD share identical powertrains, and that shared foundation is worth understanding in detail. A turbocharged 1.5L inline four-cylinder engine produces 175 hp at 5,800 rpm and 203 lb-ft of torque starting at just 2,000 rpm — that low torque peak is meaningful for everyday driving because it means the engine feels responsive from a standing start, whether pulling away from a traffic light in Morristown or merging onto a Tennessee highway.
Power routes through an 8-speed automatic transmission with a manual shift mode, sending drive to all four wheels via a standard all-wheel-drive system. The suspension setup is fully independent — MacPherson struts up front with coil springs and a stabilizer bar, and a multi-link rear with coil springs and its own stabilizer bar. That configuration gives the Terrain composed handling on the rolling hills and winding roads common to the Ridge-and-Valley Appalachian landscape, without sacrificing the ride comfort families expect on longer hauls.
| Feature | AT4 AWD | Denali AWD |
|---|---|---|
| Engine | 1.5L turbo inline-4 | 1.5L turbo inline-4 |
| Horsepower | 175 hp | 175 hp |
| Torque | 203 lb-ft | 203 lb-ft |
| Transmission | Automatic 8-speed | Automatic 8-speed |
| Drivetrain | All-wheel drive | All-wheel drive |
| Towing capacity | 1,500 lbs | 1,500 lbs |
| Fuel economy | 24 city / 28 hwy / 25 combined MPG | 24 city / 28 hwy / 25 combined MPG |
The 1,500-lb towing capacity handles a small utility trailer, a personal watercraft, or a lightweight fishing boat — enough for weekend recreation on the Tennessee River or local lakes. A trailer stability program is standard, adding electronic oversight when a load is attached. The AT4 AWD also includes engine underbody protection and all-terrain tires, giving it a modest off-road edge over the Denali for drivers who regularly use gravel access roads or forest service paths.
For buyers weighing a trade-in as part of this purchase, getting an instant cash offer on your current vehicle is a straightforward first step before visiting the lot.
​
Interior Comfort and Space Designed for Families and Professionals with the 2027 GMC Terrain
Five seats, a well-proportioned cabin, and a cargo floor that expands dramatically with the rear bench folded — the 2027 Terrain delivers practical interior dimensions that a family of four can actually use on a daily basis. Front headroom measures 40.6 inches, rear headroom 39.2 inches, front legroom 44 inches, and rear legroom 39.7 inches. Shoulder room is 57.7 inches in front and 55.7 inches in the second row, which means adults ride comfortably in both rows without feeling squeezed.
The cargo story is equally strong. about 30 cu ft behind the rear seats handles a full week of groceries, a stroller, or sports gear without reorganizing. Fold the asymmetrically split rear bench flat and that number jumps to about 63.5 cu ft — enough to load bikes, camping equipment, or festival finds from a Knoxville arts market. Cargo area tie-down hooks are standard, and a 12V power outlet in the cargo area keeps gear charged on longer hauls.
| Feature | AT4 AWD | Denali AWD |
|---|---|---|
| Curb weight | 3,687 lbs | 3,728 lbs |
| Payload | 1,163 lbs | 1,122 lbs |
All trims share: Seating: 5 · Cargo: about 30 cu ft · Towing: 1,500 lbs
Where the two trims diverge is in seat materials and adjustment. The AT4 AWD comes standard with a cloth and synthetic leather combination in Forest Storm and Mahogany Accents, with a 5-way power-adjustable driver's seat and a manually adjustable front passenger seat. The optional Convenience Package II on the AT4 AWD upgrades the passenger seat to full 5-way power adjustment with electric lumbar and adds ventilated front seats and heated rear seats — a meaningful comfort upgrade for longer commutes or road trips.
The Denali AWD raises the baseline significantly. Standard seating is genuine leather — available in After Dark Perforated Leather (black) or Light Ash Gray and Very Dark Atmosphere Perforated Leather (gray). Both front seats are power-adjustable with electric lumbar, and the driver's seat adds memory positioning for height, reach, reclining, and tilt. Heated front and rear seats are standard on the Denali. The Denali also includes a heated leather-wrapped steering wheel and memory for door mirror position.
Dual-zone automatic climate control with rear passenger vents, a wireless charging pad, a full-length floor console, and illuminated vanity mirrors round out the comfort package on both trims. Buyers ready to take the next step can start a financing application online before visiting the showroom.
​
Infotainment and Connectivity Features Tailored for Commuters in the 2027 GMC Terrain
A 15-inch center touchscreen paired with an 11-inch digital instrument cluster defines the Terrain's cockpit — and according to J.D. Power, "every Terrain comes standard with a pair of screens that do more than just impress with their size; they actually enhance functionality." That assessment holds up in practice. The center display handles navigation with satellite view, internet-fed traffic data with a 96-month subscription, and map updates also covered for 96 months — meaning buyers won't face early expiration of the system's most useful features.
Both the AT4 AWD and Denali AWD include wireless Apple CarPlay and wireless Android Auto as standard equipment, with subscriptions that effectively don't expire in any practical ownership window. Bluetooth, a Google voice assistant, built-in apps, and over-the-air OS updates are all standard. The Denali AWD adds a standard 36-month Wi-Fi hotspot subscription via embedded SIM card with up to 999 GB per month, while the AT4 AWD can add that connectivity through the optional 3 Years OnStar One package.
OnStar telematics are standard on both trims, covering remote lock/unlock, remote vehicle start, find-my-car, vehicle diagnostics, driving history and analysis, and advanced automatic collision notification. The Denali AWD extends this with theft alert and remote immobilization through its standard OnStar package.
Key Connectivity at a Glance
Both trims provide 2 front USB charging ports and 2 rear USB charging ports, an AUX jack, and a 12V cargo outlet. Steering wheel-mounted audio controls, rain-sensing wipers, and automatic headlights round out the convenience features that make the Terrain genuinely easy to live with during a busy East Tennessee workweek. The AT4 AWD also offers an optional Technology Package II (code CWN) that adds front and side parking cameras, a 360-degree surround view, traffic sign recognition, and a digital rear-view mirror — features that come standard on the Denali AWD as part of its baseline equipment, including GMC's HD Surround Vision system and Front Park Assist with front sensors.
The Denali AWD also adds a TFT instrument cluster screen and a head up display projected onto the windscreen — two features that are exclusive to the Denali in this lineup and that make a real difference for drivers who want speed, navigation, and alert data in their direct sightline.
​
Safety Technologies and Driver Assistance Systems Built for Family Safety
Every 2027 Terrain — regardless of trim — ships with a substantial standard safety suite, and the crash test record backs up the hardware. The NHTSA awarded the Terrain an overall 5-star rating, with 5 stars for frontal crash and 5 stars for side impact. The IIHS returned "Good" ratings for moderate overlap front, small overlap front (driver side), and roof strength tests, with a "Marginal" on side impact — a result worth noting for buyers prioritizing side protection.
The structural foundation includes 6 airbags: dual front airbags, front side airbags, and front-and-rear side curtain airbags. Front seatbelts include pre-tensioners and height adjustment on both driver and passenger sides. All rear seating positions have 3-point belts, and LATCH anchor points are standard for child safety seats.
On the active safety side, Forward Collision Alert monitors the road ahead and activates at speeds as low as 5 mph, triggering automatic emergency braking at low speeds when a frontal collision is imminent. Rear Cross Traffic Braking uses radar to detect vehicles crossing behind the Terrain while reversing and applies the brakes automatically — a genuinely useful feature in busy parking areas. Lane Keep Assist with Lane Departure Warning monitors lane markings and applies gentle steering corrections when the vehicle drifts without a turn signal.
Blind Zone Steering Assist goes beyond a simple warning light — it actively applies steering input to help prevent unintentional lane changes when a vehicle is detected in the blind spot. Adaptive Cruise Control maintains a set following distance on the highway, reducing driver fatigue on longer commutes. A rear occupant alert reminds drivers to check the back seat before exiting, a feature particularly relevant for families with young children.
OnStar's Advanced Automatic Collision Notification contacts emergency services in the event of a crash, and an emergency call button provides direct access to OnStar advisors. A trailer stability program is also standard, applying selective braking to counteract trailer sway when towing.

Pricing Breakdown of All 2027 GMC Terrain Trims: Denali AWD and AT4 AWD
The 2027 Terrain's two premium trims cover a $3,100 spread that reflects a meaningful step up in luxury content, technology, and standard equipment — not simply a badge change.
| Feature | AT4 AWD | Denali AWD |
|---|---|---|
| Base MSRP | $39,100 | $42,200 |
All trims share: Destination charge: $1,995
The AT4 AWD at $39,100 (plus $1,995 destination) positions itself as the trail-capable, rugged-styled choice. Its standard equipment includes all-terrain tires on 17-inch alloys, engine underbody protection, a 15-inch touchscreen, wireless smartphone integration, OnStar telematics, Adaptive Cruise Control, the full active safety suite, and cloth/synthetic leather seating. The optional Technology Package II adds the 360-degree camera system, front parking sensors, and traffic sign recognition for buyers who want the Denali's tech without the Denali's price point. The Convenience Package II adds ventilated front seats, heated rear seats, and a fully power-adjustable passenger seat.
The Denali AWD at $42,200 (plus $1,995 destination) includes all of that technology as standard equipment, and then layers in genuine leather seating, a memory driver's seat, heated front and rear seats, a heated steering wheel, chrome exterior accents, 19-inch wheels, HD Surround Vision, Front Park Assist with sensors, a head-up display, a TFT instrument cluster, and a 36-month Wi-Fi hotspot. The Denali also adds remote theft alert, remote immobilization, and memory for mirror positions.
For buyers who want to personalize further, both trims offer an optional Panoramic Sunroof, Volcanic Red Tintcoat paint, Sterling Metallic or Ebony Twilight Metallic two-tone roof options, a 3 Years SiriusXM subscription, and Mobile Service Plus in 1-year or 3-year terms. The Denali AWD exclusively offers optional 20-inch After Midnight Machined Face Aluminum Wheels, Glacier White Tricoat paint, and its choice of two perforated leather interior color combinations.
Both trims compete in a crowded segment against the Ford Escape, Honda CR-V, Toyota RAV4, and Hyundai Tucson, and each offers a distinct set of features for shoppers to compare.
​
Warranty Coverage, Maintenance, and Service Options for 2027 GMC Terrain Owners
The 2027 GMC Terrain carries a warranty package that covers the full ownership arc for most buyers. The bumper-to-bumper limited warranty runs 3 years / 36,000 miles, while the powertrain warranty extends to 5 years / 60,000 miles — protecting the engine, transmission, and drivetrain components that matter most over the long term. Corrosion protection coverage lasts 6 years / 100,000 miles, and paint coverage is 3 years / 36,000 miles.
GMC's roadside assistance program runs concurrently with the powertrain warranty at 5 years / 60,000 miles, providing manufacturer-backed support for breakdowns, flat tires, and emergency situations anywhere in the coverage area. This program is backed by GMC's brand-specific expertise and connects directly to authorized service centers for genuine-parts repairs. A scheduled maintenance plan covers 2 years / 24,000 miles, taking routine oil changes and inspections off the ownership cost ledger for the first two years.
For Terrain owners in the Morristown area, Rusty Wallace GMC's service department handles everything from routine maintenance to warranty work. You can book a service appointment online at your convenience, and it's worth checking current service and parts offers before your next visit to check current offers. The combination of a strong factory warranty and local dealer support makes long-term Terrain ownership a straightforward proposition for families and commuters who depend on their vehicle every day.
​
Awards, Expert Reviews, and Recognition Highlighting the 2027 GMC Terrain's Strengths
Third-party recognition and press coverage consistently point to the same strengths in the 2027 Terrain. MotorTrend highlighted the model's "distinctive curb appeal, with handsome truckish sheetmetal" and praised the interior for being "festooned with fancy-looking screens and luxe touches" — a characterization that fits the Denali AWD's cabin particularly well, where the 15-inch touchscreen, 11-inch digital cluster, head-up display, and leather seating create a genuinely premium environment.
Edmunds observed that "GMC decorates the interior with more soft-touch materials on the door tops, dashboard and center console, and the cabin has good space for rear passengers" — a point that matters to families who spend real time in the back seat on longer drives. The rear legroom figure of 39.7 inches and shoulder room of 55.7 inches support that assessment with hard numbers.
The NHTSA's 5-star overall safety rating and the IIHS's "Good" scores in the most critical frontal and roof strength categories add independent credibility to GMC's safety claims. For buyers cross-shopping against the Mazda CX-50, Subaru Forester, or Kia Sportage, the Terrain's combination of premium trim differentiation, standard AWD, and a proven active safety suite makes it a competitive and well-rounded choice in the compact SUV segment.
