2025 GMC Acadia Configurations: Trim Levels, Powertrain Options, and What Changes Between Them
The 2025 GMC Acadia is a three-row midsize SUV that carries over the fully redesigned platform introduced for 2024. That redesign was significant — GMC stretched the wheelbase, added a standard third row, and expanded the powertrain lineup. Understanding how the trims and configurations stack up helps buyers know what they're actually comparing when they shop.
How GMC Structures the Acadia Lineup
GMC organizes the Acadia into a series of ascending trim levels, each adding features, technology, or premium materials to the one below it. For 2025, the lineup runs through several distinct configurations, and the differences between them go beyond cosmetics — powertrain availability, safety tech, and seating materials can all shift depending on which trim you choose.
The core trim progression for 2025 includes:
| Trim | Highlights |
|---|---|
| SLE | Base trim; cloth seating, standard safety suite, 8-inch infotainment |
| SLT | Mid-tier; upgraded infotainment, additional driver-assist features, improved interior materials |
| AT4 | Off-road-oriented; distinctive styling, all-terrain tires, standard AWD, unique suspension tuning |
| Denali | Near-top luxury trim; 11-inch infotainment display, premium materials, advanced tech |
| Denali Ultimate | Top configuration; panoramic roof, hands-free driving assist, Super Cruise availability |
These trim names and their specific content can shift between model years and regional availability, so verifying exact content with a dealer or GMC's official build-and-price tool is always the accurate path.
Powertrain Configurations
One of the more meaningful decisions in the 2025 Acadia is the engine choice. Two powertrain options are available:
2.5-liter turbocharged four-cylinder — This is the standard engine on most trims. It produces around 228 horsepower and pairs with a nine-speed automatic transmission. Front-wheel drive (FWD) is the base drivetrain, with all-wheel drive (AWD) available or standard depending on the trim.
2.5-liter turbocharged four-cylinder plug-in hybrid (PHEV) — GMC introduced an Acadia PHEV configuration for the redesigned generation. This powertrain combines the same basic engine architecture with an electric motor and a battery pack that enables a meaningful electric-only driving range. The PHEV is available on select higher trims and comes standard with AWD. It carries an ePHEV designation in GMC's lineup.
The PHEV adds charging hardware, a different rear suspension setup to accommodate the battery, and changes how the drivetrain delivers power. Buyers comparing the standard and PHEV configurations are making a fundamentally different ownership decision — one that involves home charging equipment, federal tax credit eligibility (which depends on buyer income and purchase type), and different long-term fuel cost profiles.
What Changes Across Trims
Safety and Driver-Assist Technology
The base SLE comes equipped with automatic emergency braking, lane-keep assist, and rear park assist as standard features. Moving up the trim ladder adds features like adaptive cruise control with stop-and-go, lane change alert, and HD surround vision cameras. The Denali Ultimate is where Super Cruise — GM's hands-free highway driving assist system — enters the picture, though that feature requires a subscription after an initial trial period.
Infotainment and Display Size
The 8-inch touchscreen on the SLE is functional, but upper trims step up to an 11.3-inch diagonal infotainment display with a higher-resolution interface and more embedded navigation capability. Wireless Apple CarPlay and Android Auto are available across trims, though wired connections may be standard on lower configurations.
Seating and Interior 🪑
The Acadia seats up to seven passengers across three rows. Cloth upholstery is standard at the SLE level. The SLT introduces leather-appointed seating, and the Denali trims use premium perforated leather with more extensive soft-touch surfaces. Heated front seats appear in the mid-tier and above; ventilated seats and heated second-row seats are upper-trim features.
AT4 as a Distinct Configuration
The AT4 sits outside the standard luxury progression. It's built for buyers who want some off-road credibility without going to a dedicated off-road truck. It includes two-speed AWD with an off-road mode, all-terrain tires, underbody protection, and unique exterior trim with blacked-out accents. The AT4 is not a Denali competitor — it's aimed at a different use case entirely.
Drivetrain Options by Trim
Not every configuration offers every drivetrain combination:
- FWD is the standard setup on SLE and SLT
- AWD is available on SLE and SLT, standard on AT4 and Denali trims
- The PHEV configuration is AWD-only and available on select trims — not the base SLE
The Variables That Shape Your Actual Decision
Trim level is only part of what determines what you'll pay and what you'll get. Regional dealer inventory affects which configurations are physically available. PHEV tax credit eligibility depends on your income, how you finance the vehicle, and IRS rules that can change year to year. Fuel savings from the PHEV depend on how many miles you drive, whether you charge regularly, and local electricity rates versus gas prices.
The difference between a well-equipped SLT and an entry Denali can be surprisingly small — or surprisingly large — depending on which options are packaged in. And the AT4's off-road capability only matters if the roads and conditions you actually drive justify it.
What the right configuration looks like depends entirely on your specific driving needs, budget, and how the trim content lines up with how you actually use a vehicle day to day.
