When it comes to full-size SUVs, interior space is a top consideration. The 2025 GMC Yukon and GMC Yukon XL both offer spacious, well-appointed cabins to comfortably carry passengers and cargo. But how do they compare in terms of interior dimensions and seating capacity? In this post, we'll take a closer look at the differences in interior space between these two GMC SUVs.
Passenger Capacity
The 2025 GMC Yukon comes standard with seating for 8 passengers across its Elevation, AT4, Denali, Denali Ultimate, and AT4 Ultimate trim levels. The longer wheelbase GMC Yukon XL expands that capacity to 9 passengers with its additional interior room. Both SUVs offer a choice of second row bucket seats or a 60/40 split-folding bench.
Cargo Volume
With all the seats up, the GMC Yukon provides 25.5 cubic feet of cargo space behind the third row. Folding the third row expands that to 72.6 cubic feet, and with both back rows folded, you get a generous 122.9 cubic feet of maximum cargo volume.
The larger GMC Yukon XL increases those figures significantly. It has 41.5 cubic feet behind the third row, 93.8 cubic feet behind the second row, and a cavernous 144.7 cubic feet with all rear seats folded down. That's over 20 extra cubic feet of maximum cargo capacity compared to the standard Yukon.
Legroom and Headroom
Both the 2025 GMC Yukon and Yukon XL provide expansive headroom and legroom for passengers in all three rows:
- Front headroom/legroom: 42.3 inches/44.5 inches
- Second row headroom/legroom: 38.9 inches/42.0 inches
- Third row headroom/legroom
- Yukon: 38.2 inches/34.9 inches
- Yukon XL: 38.2 inches/36.7 inches
As you can see, the key difference is in third row legroom, where the Yukon XL provides nearly 2 extra inches to stretch out compared to the Yukon.
