All trims of the Acadia are powered by a new 2.5L turbocharged engine that delivers more power and more trailering capability than the previous generation. Producing 328 horsepower and 326 lb-ft of torque, the new engine is paired with an eight-speed automatic on all trims with available all-wheel drive, including an exclusive off-road-capable Active Torque Control AWD system on the redesigned Acadia AT4. The powertrain helps maintain Acadia's strong trailering capability. When properly equipped, it has a max trailering rating of 5,000 pounds.
