The 2026 GMC Acadia represents a massive shift for the model. It is bigger, more powerful, and more technologically advanced than any Acadia before it. Naturally, this redesign raises questions for long-time GMC owners in Sidney and Westerville.
At Chesrown Chevrolet GMC, we believe in empowering our customers with technical facts, not sales fluff. Our product specialists have compiled the top 10 questions we receive about the all-new Acadia to help you make an informed decision.
No. GMC has replaced the previous V6 with a new, high-output 2.5L Turbocharged 4-Cylinder engine. Do not let the cylinder count fool you, this new engine is more powerful than the old V6, delivering 328 horsepower and 326 lb-ft of torque.
When equipped with the factory Trailering Package, the 2026 Acadia can tow up to 5,000 pounds. This is sufficient for hauling a 20-foot boat, a pair of snowmobiles, or a medium-sized camper.
No. Despite being a high-performance turbocharged engine, GMC engineers have calibrated the 2.5L Turbo to run efficiently on Regular 87 Octane unleaded fuel. You get peak performance without the premium price at the pump.
All models utilize an 8-Speed Automatic Transmission. Unlike a CVT (Continuously Variable Transmission) found in some competitors, this 8-speed provides distinct shift points, which is superior for towing and maintains a connected driving feel on the highway.
Yes, significantly. The 2026 Acadia is 10.6 inches longer and 3.2 inches taller than the 2023 model. This growth is directly allocated to the cabin, solving the “tight third row” complaint of the previous generation.
The Acadia offers two seating configurations:
Thanks to the larger chassis, the third row now comfortably accommodates adults, not just small children.
You now have 23.0 cubic feet of storage with all seats upright, nearly 80% more than the previous generation. With both rear rows folded flat, the maximum cargo capacity is a cavernous 97.5 cubic feet.
Yes. Super Cruise™ hands-free driver assistance technology is available on Elevation and AT4 trims, and it is standard on the Denali Ultimate. This system allows for hands-free driving on compatible roads like I-75, and it even works while towing.
Every 2026 Acadia, regardless of trim, comes standard with a 15-inch Premium GMC Infotainment System. The screen is portrait-oriented (vertical), which allows for a better view of navigation maps and splits-screen multitasking.
AT4 (Off-Road): Features an Active Torque Control AWD system that can send torque to specific wheels for traction on dirt or snow. It also has a factory lift for roughly an inch of extra ground clearance, red tow hooks, and all-terrain tires.
Denali (Luxury): Focuses on on-road refinement with Continuous Damping Control suspension, 22-inch aluminum wheels, and a leather-wrapped interior with laser-etched wood accents.
The best way to understand the 328-horsepower engine or the 15-inch screen is to experience them firsthand. Visit Chesrown Chevrolet GMC in Sidney to speak with a product expert who knows the engineering behind the badge.
