The 2015 redesign brought a sumptuous and quiet interior, power folding second- and third-row seats, and available advanced safety features.
Top-trim Denali versions offer a stronger V8 and plusher interior finishes.
The Yukon XL is exceptionally quiet, in fact, it's a lot like a good luxury car.
Handling is sound and responsive enough, with no excessive body lean, but the feeling of bulk is ever present.
Adaptive cruise control, blind spot warning, rear cross-traffic alert, forward collision and lane departure warning are available.
Choosing the top Yukon XL Denali trim with its Magnetic Ride Control improves the ride significantly, pays dividends in handling, but gets very pricey.
Instead, we'd opt for the Suburban LTZ over the Yukon XL.
That model pairs the Magnetic Ride Control suspension with the more efficient 5.3-liter engine, which is a combination unavailable from GMC.
Changes for 2016 include available lane-keeping assist.
