2027 GMC Terrain: New 8-Speed Automatic, Trims, Features, and Specs

October 18, 2026 · 4 min read

For 2027, the GMC Terrain pairs its 1.5L turbocharged engine with an eight-speed automatic transmission across the lineup. The 2026 Elevation FWD previously used a CVT, while AWD configurations used the eight-speed automatic. As a compact SUV focused on everyday usability, the Terrain combines its turbocharged engine with an 8-speed automatic transmission across the lineup. Here is what the 2027 GMC Terrain brings, and why buyers shopping for a GMC auto SUV in the Fairless Hills area are paying attention.

Powertrain

The 2027 GMC Terrain runs a 1.5L turbocharged four-cylinder engine producing 175 horsepower and 203 lb-ft of torque. An 8-speed automatic transmission is standard. AWD is available on Elevation and standard on AT4 and Denali.

Fuel economy comes in at an EPA-estimated 28 MPG highway on the Elevation trim. The AT4 and Denali trims are rated at 26 MPG highway.

GMC now lists the eight-speed automatic on the 2027 Elevation, while the 2026 FWD Elevation used a CVT. It works with the 1.5L turbocharged engine to deliver a familiar driving experience for daily commuting and highway driving. The eight-speed automatic uses fixed gear ratios, unlike the CVT previously offered on the 2026 Elevation FWD. Buyers comparing model years should note this transmission difference.

Three Trims, Three Different Buyers

Elevation is the entry trim and the one most buyers start with. It comes standard with heated front seats and a heated steering wheel, a 15-inch GMC infotainment system with Google built-in, an 11-inch driver information center, and more than 16 safety and driver assistance features. The 2026 Terrain offered the same three core trims, but its Elevation FWD configuration used a CVT. For 2027, GMC lists an eight-speed automatic as standard on Elevation.
AT4 is the trail-ready option. It adds an AT4-exclusive Terrain drive mode, a lifted ride height, and 17-inch all-terrain tires. The AT4 offers up to six selectable drive modes: AWD, Normal, Snow/Ice, Off-Road, Tow/Haul, and the AT4-exclusive Terrain Mode.
Denali is the top trim. Heated and ventilated front seats, heated rear outboard seats, animated headlamps and taillamps, HD Surround Vision, and 19-inch wheels define the Denali's position in the lineup.

Seating, Cargo, and Practicality

The GMC Terrain seats five passengers across two rows. There is no third-row option on this vehicle. Cargo volume reaches 63.5 cubic feet with the rear seats folded and 29.8 cubic feet behind the second row. The rear seats split 60/40 and the Terrain includes rear underfloor storage as well. Available features include a panoramic sunroof, two-tone roof, and an AutoSense power liftgate. When properly equipped with the Trailering Package, the Terrain can tow up to 1,500 lbs.

For a two-row SUV, the Terrain's cargo numbers are competitive. The 29.8 cubic feet behind the second row handles everyday loads without issue. The 63.5 cubic feet with seats folded puts it in a usable range for buyers who occasionally need to move larger items without renting a truck. The rear underfloor storage is a practical addition that keeps smaller items out of sight and organized. The Terrain offers 29.8 cubic feet of cargo space behind the second row and 63.5 cubic feet behind the first row, giving buyers useful space for everyday cargo and larger loads.

GMC AT4 vs Denali: Differences, Features & Which Is Better

When you're looking at the AT4 vs Denali trim lines on a GMC, it's not just that one is better than the other; it's that they're designed to serve different purposes even though they're both more upmarket than lower trims. The AT4 is designed around off-road ability, toughness, and conquering obstacles with a smile, where the Denali trim is designed to impress you with luxurious materials, cutting-edge technology, a soft ride, and a visually elegant aesthetic. Though options vary across the GMC model line, this knowledge can help determine if the added cost of higher trim levels is worth it for your lifestyle. What Does GMC AT4 Mean? AT4: AT4 brings the capability. If it's applicable to the vehicle's platform and body style the AT4 trim may be equipped with all-terrain tires, new drive modes, additional ride height, underbody protection (skid plates), recovery hooks, and the ability to tackle tougher terrain. Taking the example above with the 2026 GMC Terrain, the Terrain AT4 as standard gets AWD, a lifted height and underbody protection, 17-inch all-terrain tires, as well as the Terrain AT4 exclusive drive modes (Terrain Mode). With bigger vehicles like our GMC Yukon and truck lineup, the AT4 experience really focuses on traction and ability. More off-road capability All-terrain tires Additional traction-focused equipment Rugged exterior styling Extra confidence on dirt, gravel, and uneven terrain A GMC that can handle more than normal paved-road driving What Does GMC Denali Mean? On the higher end of the Terrain spectrum is the 2026 GMC Terrain Denali. Unlike the AT4 and that particular model's main mission, the Denali's main intention here is to offer the plushest ride with the most distinctive looks as well as tech features over the 2026 GMC Terrain Denali trim levels that are sure to add an upscale flair to your next family or weekend getaway. Added features include a premium interior with leather-appointed seating and heated and ventilated front seats, as well as the addition of advanced tech features such as HD Surround Vision, GM’s popular Rear Camera Mirror, and one-off Denali styling. 20-inch wheels, for a more commanding stance and enhanced style. A more luxurious interior Premium comfort features Upscale exterior styling Advanced technology A refined everyday driving experience More premium features without moving to a separate luxury brand AT4 vs. Denali: Where Does Your Money Go? Feature AT4 Denali Primary Focus Off-road capability Premium comfort & luxury Styling Rugged and adventure-focused Upscale and sophisticated Terrain Capability Enhanced Primarily road-focused Interior Premium with durable touches More luxurious materials and finishes Technology Advanced More premium technology options Best For Drivers who want capability Drivers who prioritize comfort However, what is crucial to note is that a more expensive vehicle does not instantly translate to a better vehicle for everyone. It translates to an optimized vehicle. Is AT4 Better for Off-Road Driving? But on the other hand, if you’re prioritizing the capacity for off-road adventure more often than not, the AT4 is probably going to make the most sense for you.The entire point of GMC’s lineup of AT4 variants, of course, is to equip models with an array of capability enhancements that go beyond those found in the road-legal variants. The factory-provided suspension lift for the 2026 GMC Sierra 1500 AT4 is a case of this, as is class-leading trailer-pulling prowess and equipment geared specifically for adventuring over dirt or rock trails. Is Denali Worth It for Daily Driving? For many drivers – especially commuters – this is where the Denali treatment might actually start to make sense. “You’re more likely to encounter these luxury items on your daily commute than use some specialized off-road equipment each week,” says Edmunds. The upcoming 2026 GMC Yukon Denali, for instance, gets a larger 15-inch head-up display and optional power sliding console, along with Magne Ride damping (on a top Denali trim for the first time). And if family trips and the highway are more common modes for you, Denali’s priorities make more sense. What About the Price Difference? The price gap can swing wildly depending on the specific GMC model and equipment. For example, right now GMC has the 2026 Terrain AT4 on offer with an MSRP starting at $41,395 and a 2026 Terrain Denali with a starting price of $43,895. That puts the Denali at about a $2,500 premium over the AT4 before you've added even one option or assessed destination charges, delivery, handling, documentation, etc.For large, premium GMC SUVs and pickup trucks, this could be different indeed.Comparing the specific trim level of AT4 and Denali of the GMC vehicle you want is far more productive than trying to guess that price difference is universal or standard on equivalent equipment across the product lineup. Which One Should You Choose? Choose AT4 if you: Regularly drive on gravel, dirt, or rough roads Want stronger off-road capability Prefer rugged styling Want terrain-focused equipment Plan to use your GMC for outdoor adventures Choose Denali if you: Spend most of your time on paved roads Want a more luxurious cabin Prioritize premium comfort Want upscale exterior styling Value additional technology and convenience features AT4 or Denali: What's Actually Worth Paying For? It all depends on what you actually use it for If you'd like your GMC to take you off the pavement And give you more in terms of driving dynamics off-road the AT4 can spend your additional money on you know the equipment that would enjoy going to the wilderness The Denali puts that money, if the road primarily is your home the family or your daily vehicle into the items you gonna use daily so in the interior of premium the technologies within it. So. At the end of the day, neither package is the top shelf; at the end of the day, they serve very specific purposes. The AT4s are focused on capability; Denalis are focused on the finer touches.
