2027 GMC Yukon & Yukon XL

Yukon or Yukon XL: compare space with every seat in use

The most useful cargo measurement for a family trip is often the room behind the third row. GMC lists 25.5 cubic feet there for Yukon and 41.5 cubic feet for Yukon XL. With the rear rows folded, maximum capacity rises to 122.8 and 144.5 cubic feet respectively. Seating is available for up to eight, depending on configuration.

Choose Yukon if it fits your passengers and gear comfortably. Put Yukon XL on your list when luggage, team equipment or vacation supplies regularly travel with a full cabin. Measure your garage and think about your usual parking spaces before choosing the longer body.

Why the 3.0L Duramax diesel deserves a closer look

The available Duramax 3.0L Turbo-Diesel delivers 305 horsepower and 495 lb.-ft. of torque. The lineup also offers 5.3L and 6.2L V8 gasoline engines, depending on configuration. For buyers who spend substantial time on the highway or carry passengers and gear on longer trips, the diesel is an engine worth comparing in person.

A higher diesel price per gallon does not automatically mean a higher fuel cost per mile. The comparison is fuel price per gallon divided by miles per gallon. Diesel can cost more at the pump and still cost less per mile if the fuel-economy improvement is large enough.

For example, a 20% fuel-price premium requires more than a 20% improvement in miles per gallon to produce a lower fuel cost per mile. This is a mathematical comparison, not a claimed 2027 Yukon MPG rating or a promise of savings. Use the ratings for the exact engines and drivetrains you are considering, your expected driving mix and local fuel prices.

Also compare the diesel's purchase-price difference, DEF, maintenance and annual mileage. A low-mileage buyer may value the engine's driving character without recovering an added upfront cost through fuel savings. We can help you compare those tradeoffs instead of deciding from one fuel-price sign.

Compare Elevation, AT4 and Denali models

The 2027 lineup includes Elevation, AT4, AT4 Ultimate, Denali and Denali Ultimate. AT4 models emphasize off-road equipment; Denali models emphasize premium appointments. Available equipment includes Super Cruise driver assistance and Air Ride Adaptive Suspension, depending on trim and configuration.

Start with your must-haves: engine, seating arrangement, body length, trailering equipment and seat comfort. Then compare the actual window stickers. A trim upgrade is most useful when it adds features you will regularly enjoy.

Match the Yukon to your towing plans

GMC advertises up to 8,400 pounds of towing for a properly equipped Yukon. That is a lineup maximum, not the rating of every diesel, V8, XL or four-wheel-drive configuration. Check the exact vehicle's trailering information, payload and hitch requirements before purchase.

Tell our team the trailer's loaded weight and the number of people and amount of cargo you expect to carry. Those details help make the comparison meaningful for travel from Northwest Indiana to your next campsite or lake weekend.
