Both vehicles make a compelling case for themselves, with impressive performance values and excellent commitment to interior quality.
Let's start with a review of the powertrain motivating the GMC Terrain. As you can see in the chart above, it achieves a higher EPA-estimated MPG rating than the Buick Envision thanks to standard front-wheel drive, but it outputs less power. That being said, if you opt for an all-wheel-drive configuration, you can still reach the same maximum 1,500-pound towing capacity that you'll get from its Buick cousin.1,2
We didn't cover AWD-equipped fuel efficiency for the GMC Terrain in the chart – specifically because the Buick Envision comes standard with AWD while the GMC Terrain kicks off with FWD. Swap to AWD for the GMC Terrain, and you'll get up to an EPA-estimated 24/28/25 MPG (City/Highway/Combined) with the Elevation trim5 or 24/26/25 MPG (City/Highway/Combined) with the AT4 and Denali editions.6 These are still impressive values that compete nicely with the Envision rating of 22/28/25 MPG (City/Highway/Combined).4
In past years, the GMC Terrain had off-road cred with the rugged AT4 and luxury-level comfort via the Denali. However, the last model year saw a single-trim lineup, with just the Elevation on offer. Well, GMC engineers have expanded the menu to a trio of options, bringing back the AT4 and Denali versions, letting drivers choose a practical, trail-ready, or opulent Terrain.
With the GMC Terrain AT4, you get a front skid plate with a steel underbody shield, an AutoSense power liftgate, roof-mounted side rails, and all-terrain tires. You won't find many of these trail-conquering appointments with the Buick Envision. Instead, the mid-tier Buick Envision Sport Touring leans into a more athletic appeal, donning exclusive 20-inch wheels with Carbon Flash Metallic paint and a High-Gloss Black center cap, sporty styling elements, and upgraded on-road safety features.
When you compare GMC Terrain to Buick Envision trim levels, you'll see many similarities overall. Though your choice between the two may hinge on your preference for a sporty and more powerful drive in the Buick Envision or an outdoor adventure machine with the GMC Terrain.
To further convey how similar these SUVs are, let's bust out a measuring tape and compare the GMC Terrain vs. Buick Envision exterior and interior dimensions. While height can vary for the GMC Terrain depending on your chosen trim level, these models' lengths are very similar in length and width. For instance, the Terrain is 0.4 inches wider than the Envision, while the Buick SUV is 1.7 inches longer. Though we don't have official ride height measurements for the 2026 Envision quite yet, we know the GMC Terrain can ride high over debris with a ground clearance of 6.52 inches on AT4 and Denali trims – Elevation models are a bit closer to the ground at 5.75 inches.
On the inside, you'll find slightly more storage and passenger space with the GMC Terrain than with the Buick Envision. The former has an additional 4.6 cubic feet of cargo room when the rear seats are in their upright position.
Take a look at GMC Terrain vs. Buick Envision passenger measurements, and you'll see that the Terrain provides more in nearly every category, with the one exception being second-row shoulder room. That being said, with 100.4 cubic feet of passenger volume overall, the Envision cabin will still be plenty comfortable for all occupants. Where the Envision interior fills some of its open space with sweeping style lines and design flourishes, the GMC Terrain takes a practical approach to interior styling. These characteristics carry over to each SUV's dash – you'll find a premium 30-inch ultrawide screen in the Envision or a more value-driven 15-inch display in the Terrain.
GMC Terrain vs. Buick Envision safety and driver-assistance systems is a close race. Ultimately, both models deliver extensive technologies to keep you and your loved ones secure on the road. However, the Envision does have some more advanced capabilities as standard, which is to be expected given its luxury designation. Hill Descent Control, Rear Pedestrian Alert, Traffic Sign Recognition, and HD Surround Vision are all standard features in the Envision, while they're available via higher tiers of the Terrain. The trade-off is that the GMC Terrain has a more accessible starting price.
The GMC Terrain vs. Buick Envision standard safety features that are equal put both models in a great place for safety, bringing standard Automatic Emergency Braking, a Forward Collision Alert, a Lane Keep Assist with Lane Departure Warning, and more to your drive. This area of comparison is more or less a tie, and comes down to your preference for innovative technology or a value-oriented sticker price.
