The 2026 GMC Acadia debuts the third model year for the third-gen crossover. Compared to the preceding 2025 GMC Acadia, the 2026 Acadia introduces relatively minor updates and changes. That said, the crossover is now equipped as standard with a new Key Card feature, providing vehicle access for up to eight users.
For those readers who may be unaware, the Key Card feature allows multiple users to unlock, lock, and start the vehicle. To unlock a vehicle using a properly programmed key card, users simply need to tap the card on a rectangular symbol located near the window on the driver’s side door. The vehicle can then be started for a brief period after unlocking the door using the key card. To lock the door using the key card, make sure the vehicle is off, then tap the card again on the rectangular symbol.
If the engine is not started shortly after unlocking the door using a key card, users will need to unlock the vehicle again using the card. Users can have up to eight key cards tied to a single vehicle, making it easy for several individuals to have access to the same vehicle. Notably, this feature is already equipped by the 2025 Cadillac Lyric, while the 2026 Chevy Traverse and 2026 Buick Enclave will offer the feature as well.
Beyond the new standard key card feature, the 2026 GMC Acadia is expected to offer only a few small updates, including a revised exterior paint options list, with White Frost Tricoat (paint code G1W) replaced by Glacier White Tricoat (paint code G4J), similar to the 2026 GMC Terrain.
As the mechanical specs, the 2026 GMC Acadia will carryover the same powertrain specs as the preceding 2025 model year, once again cradling the turbocharged 2.5 I4 LK0 gasoline engine. Output is rated at 328 horsepower and 326 pound-feet of torque, while under the skin, the Acadia rides on the GM C1 platform. Production is expected to kick off at the GM Lansing Delta Township plant on July 14th, 2025.

Wow! General Motors really loves developing new ways for thieves to get access to its vehicles.
I have notices the in crease in size and the 4 cylinder have not helped sales. In fact they are down since the changes.
I know we will look for another model and not buy the present one to replace our 2021,
Source? Last year was a changeover year, even so Q4 was the second highest quarter in terms of sales since 2021 during the crazy covid buying times. Reviews have been excellent and the powertrain (apart from the sound) has been given excellent feed back in the power and efficiency realms. So other than your obvious and incorrect correlation to engine size and vehicle performance you are trying to hint at, your argument holds no merit. I am guessing you are applauding the other brands who are also downsizing engines?
it’s okay to be wrong. While i don’t personally love the sound of the 4 cyl, the sales numbers aren’t lying. Enclave and Acadia have had record numbers at the tail of last year, and in Q1 of this year.
The last 8 years I have bought about 3 G.M. vrhicles with 4 cylinder TURBO CHARGED
engines. Step on gas go like “BAT OUT OF HELL”. Still get great gas milage.
Sounds great to me real quiet. Maybe da sound is in your head. Something may be RETAILING around.??? Stop giving you KNOGIN A KNOCKIN. ” SOUNDS” good to us.
