If you need room for extra passengers or just more flexibility, a three-row SUV can make everyday driving much easier. But with several GMC SUV models to choose from, it can be tough to know which ones actually offer a third row. GMC currently offers three SUVs with third-row seating: Acadia, Yukon, Yukon XL. All three can carry more passengers —but they differ in size, cargo space, overall capability, and other factors. Explore our comprehensive guide at GMC of Riverfront Park to easily discover which model is the ideal fit for you!
Which GMC SUVs Have Three Seating Rows?
The GMC three-row lineup gives shoppers options ranging from a midsize SUV to two full-size models.
GMC Acadia
A midsize SUV with seating for up to eight, depending on configuration.
GMC Yukon
A full-size SUV with seating for up to eight and generous passenger and cargo space.
GMC Yukon XL
A longer version of the Yukon that provides even more room for passengers and cargo.
GMC Acadia
The Acadia is the smaller option in GMC's three-row lineup, making it a good fit for drivers who want extra seating without moving into a full-size SUV. The current Acadia offers seating for up to eight passengers in select configurations. Other configurations seat seven with second-row captain's chairs, and its third row provides 32.1 inches of legroom, while the second row has 41.5 inches.
The Acadia also makes getting into the third row easier with available Smart Slide second-row seating. The third row can fold when you need additional cargo room — giving you flexibility for everything from school activities to weekend trips.
GMC Yukon
If you need more space and capability, the GMC Yukon steps up to a full-size SUV. It can seat up to eight passengers and provides more room in all three rows than many midsize SUVs. The Yukon has 25.5 cubic feet of space for storage behind the third row and as much as 34.9 inches of legroom in that third row of seats. Folding the rear seats opens up even more room when you need to carry larger items.
The Yukon is also a strong option for drivers who need towing capability along with passenger space. Its larger size can make it especially appealing for families who regularly travel with people and luggage or recreational equipment.
GMC Yukon XL
The Yukon XL takes the Yukon formula and adds even more length. That extra size is especially useful if you frequently have a full cabin and still need room behind the third row. It offers 41.5 cubic feet of space for cargo behind the last row and up to 36.7 inches of legroom in the third row. That’s considerably more cargo room than the standard Yukon offers with all three rows in use.
Think of the Yukon XL as the choice for shoppers who don't want to compromise much on passenger or cargo space. It's well-suited for large families and road trips — or drivers who regularly carry bulky gear.
How to Choose the Right GMC 3-Row SUV
All three models give you a third row, but that doesn't mean they serve exactly the same purpose. Consider these factors when comparing them:
- Passenger needs: Think about how many people you typically carry and how often the third row will be occupied.
- Cargo space: If you regularly carry larger items (e.g. strollers, sports equipment, luggage), compare cargo room with all three rows in use.
- Vehicle size: The Acadia is easier to maneuver than the larger Yukon and Yukon XL, while the full-size models provide more interior space.
- Towing and capability: If towing is part of your plan, the Yukon lineup may be worth a closer look.
- Daily driving: Consider where you park and how much of your driving takes place in busy areas before choosing a larger SUV.
