2025 GMC Acadia AT4: Features, Specs, Performance, Price, and Review Guide

The 2025 GMC Acadia AT4 is a three-row midsize SUV designed to combine everyday family practicality with genuine off-road-oriented equipment. As part of the redesigned Acadia generation, the AT4 stands apart from the standard Elevation and upscale Denali by focusing more heavily on all-wheel-drive capability, rugged styling, suspension tuning, and traction management. It is especially interesting for drivers who want a family SUV that can handle dirt roads, snow, trails, and rougher conditions without moving into a traditional body-on-frame truck-based SUV.

For 2025, the Acadia AT4 uses a 2.5-liter turbocharged four-cylinder engine, an eight-speed automatic transmission, and standard all-wheel drive. GMC rates the engine at 328 horsepower and 326 lb-ft of torque, giving the large three-row SUV substantial low- and mid-range pulling power. GMC also equips the AT4 with several hardware upgrades intended to make it more capable away from paved roads.

2025 GMC Acadia AT4 Engine and Performance

The heart of the 2025 GMC Acadia AT4 is its 2.5L turbocharged inline-four engine. It produces 328 horsepower at 5,500 rpm and 326 lb-ft of torque at 3,500 rpm, paired with a conventional eight-speed automatic transmission. This powertrain is shared across the Acadia lineup, giving the AT4 strong performance without requiring a larger V6 or V8 engine.

The important difference is how the AT4 uses that power. Active Torque Control all-wheel drive is standard, and the system is designed to distribute torque where it is needed for improved traction. GMC also gives the AT4 an off-road-tuned suspension with hydraulic rebound control, a taller ride height, and a wider track than the standard configuration. These changes are intended to improve stability and control when the vehicle leaves smooth pavement.

For towing, the 2025 Acadia lineup can reach a 5,000-pound maximum towing capacity when properly equipped. That gives the AT4 enough capacity for many recreational trailers, small boats, utility trailers, and outdoor equipment. Actual towing capability depends on configuration and equipment, so buyers should confirm the specifications for the individual vehicle.

AT4 Off-Road Capability and Exterior Design

The AT4 is more than an appearance package. GMC gives the Acadia AT4 several mechanical and exterior changes intended for light off-road use. Its lifted ride height, off-road-tuned suspension, all-terrain tires, and Active Torque Control AWD distinguish it from the road-focused versions of the Acadia.

The AT4 uses 18-inch dark machined aluminum wheels with all-terrain tires, while its front fascia incorporates red recovery hooks and integrated skid plates. The higher ride height and more aggressive front design also contribute to improved approach capability when traveling over uneven terrain.

Another important feature is the Traction Select System, which includes a Terrain mode designed for conditions where additional traction and controlled wheel movement are important. The AT4 also includes Hill Descent Control, which can help manage vehicle speed during controlled descents on steep or uneven surfaces.

These features make the AT4 particularly suitable for gravel roads, muddy access roads, snowy conditions, camping routes, and moderate trails. However, it is still a midsize crossover SUV rather than a dedicated rock-crawling vehicle. Drivers should understand the limits of its tires, ground clearance, suspension, and unibody construction before attempting difficult terrain.

Interior, Seating, and Technology

Inside, the 2025 GMC Acadia AT4 combines a practical three-row layout with modern technology. The Acadia is considerably larger than the previous generation, giving it useful passenger and cargo space. GMC lists maximum cargo capacity at 97.5 cubic feet behind the first row, with approximately 57.3 cubic feet behind the second row and 23.0 cubic feet behind the third row.

The AT4 features a 15-inch diagonal GMC Premium Infotainment System, making the dashboard one of the most noticeable parts of the cabin. The system supports connected applications and offers available Google built-in functionality, while compatible phones can use wireless Apple CarPlay and wireless Android Auto. An 11-inch driver information display provides additional vehicle and trip information.

Comfort equipment includes heated front seats, an eight-way power driver’s seat, a heated steering wheel, remote start, and a Bose premium 12-speaker audio system. Depending on configuration and packages, buyers can add features such as heated and ventilated front seats, heated second-row outboard seats, an eight-inch head-up display, and other convenience equipment.

This combination makes the AT4 practical for both daily commuting and longer family trips. The three-row configuration also gives it an advantage over smaller two-row SUVs when passenger flexibility is important.

Safety Features and 2025 IIHS Rating

Safety is another major consideration when evaluating the 2025 GMC Acadia AT4. The Insurance Institute for Highway Safety awarded the 2025 Acadia a Top Safety Pick designation for vehicles built after January 2025. The Acadia received a Good rating in the small-overlap front test, an Acceptable rating in the updated moderate-overlap front test, and a Good rating in the updated side test.

The Acadia also received a Good rating for standard vehicle-to-vehicle front crash prevention. Its standard enhanced automatic emergency braking and front pedestrian and bicyclist braking systems were evaluated by IIHS. Pedestrian front crash prevention received an Acceptable rating.

Standard safety technology includes features such as blind-spot detection, lane-departure warning and lane-departure prevention, along with other driver-assistance systems. Some equipment, including rear automatic braking, depends on configuration or options.

As always, driver-assistance systems are designed to supplement attentive driving rather than replace it. Weather, visibility, road conditions, and system limitations can affect performance.

2025 GMC Acadia AT4 Price and Value

When new, GMC listed the 2025 Acadia AT4 with an MSRP starting around $52,895, before taxes, fees, and optional equipment. The exact transaction price could be higher depending on packages, destination charges, accessories, dealer pricing, and availability.

In 2026, shoppers considering a used 2025 GMC Acadia AT4 should look beyond the original sticker price. Vehicle condition, mileage, maintenance records, tire condition, accident history, and remaining warranty coverage can have a major effect on actual ownership value.

The AT4’s additional off-road hardware is particularly useful for buyers who genuinely need AWD and rough-road capability. Drivers who spend almost all their time on highways may find that some of the AT4’s specialized equipment is less important than comfort, fuel economy, or luxury features.

Is the 2025 GMC Acadia AT4 Worth Considering in 2026?

The 2025 GMC Acadia AT4 occupies an interesting position in the midsize SUV market. It combines the practicality of a three-row family crossover with 328 horsepower, standard AWD, all-terrain tires, lifted ride height, off-road suspension tuning, Terrain mode, Hill Descent Control, and a 5,000-pound maximum towing capability.

For a 2026 buyer, the most important step is to match the vehicle’s equipment with actual driving needs. A used AT4 should receive a careful inspection covering the tires, suspension, brakes, underbody, AWD system, engine, transmission, electronics, and service history. Vehicles that have spent substantial time on rough trails deserve additional attention underneath.

Overall, the AT4 provides a distinctive balance: it remains a comfortable family SUV while adding meaningful hardware for drivers who regularly encounter snow, gravel, mud, uneven roads, and outdoor adventures.
