Eight passengers take up a lot of space, and so does all the stuff they need to carry. But the 2021 GMC Yukon has room to spare. Even the standard-length 2021 GMC Yukon has a whopping 163.8 cu-ft of passenger volume. There is 25.5 cu-ft of space for whatever luggage your crew needs, too. Do you need more?

2. Luxury Treatment

At the top of the line, the 2021 GMC Yukon Denali trim has everything you're looking for in luxury treatments. The Denali includes many exclusives, like perforated premium leather-wrapped seats. Scattered throughout the cabin is stylish chrome trim. And a power-sliding center console improves access and legroom between the couch-like second-row captain's chairs.

3. Lift the Height on Your Ride
