GMC Acadia: Midsize 3-Row SUV

What Makes the Acadia a Great 3-Row SUV?

The GMC Acadia is a midsize SUV with three rows that fits families who want passenger flexibility without the bulk of a full-size truck-based SUV. It seats up to 8 passengers in the Elevation trim, or 7 in AT4, Denali, and Denali Ultimate trims.

The second-row smart slide seats make third-row access simple. Pull the lever and the seat slides forward, creating a wide opening. That means less hassle when you are loading kids or adults into the back.

With 41.5 inches of second-row legroom and 32.1 inches in the third row, the Acadia gives adults a fighting chance in the back. The available panoramic sunroof, heated second-row captain's chairs, and power-folding third row add daily convenience.

Yukon: Full-Size Passenger Comfort

The GMC Yukon is a full-size SUV with third-row seating that offers more space than the Acadia. It seats up to 8 passengers and delivers 34.9 inches of third-row legroom. That is noticeably more than the Acadia, and adults will appreciate the difference on longer trips.

The Yukon also brings premium features like available Super Cruise, a 16.8-inch infotainment screen, and tri-zone climate control. The rear-seat media system with dual 12.6-inch screens keeps passengers entertained. And with up to 72.5 cubic feet of cargo space behind the second row, you can pack for a full family vacation.

Yukon XL: Maximum Cargo and Passenger Room

The GMC Yukon XL is the largest 3-row SUV GMC builds. It adds 11.7 inches of length compared to the standard Yukon. That translates into 36.7 inches of third-row legroom and 41.5 cubic feet of cargo space behind the third row. That is a huge jump from the Yukon's 25.5 cubic feet.

If your family regularly fills all three rows and still needs room for luggage, sports gear, or road-trip supplies, the Yukon XL is the answer. It shares the same premium features as the Yukon, including available massaging front seats, a Bose premium audio system, and a panoramic sunroof.
