Like its slightly smaller sibling, the massive Yukon XL gets an independent rear suspension that improves ride comfort, handling, and, as a result of better packaging, third-row room.
The standard 5.3-liter V8 is mated to a 10-speed automatic transmission, and that powertrain supplies plenty of predictable and smooth power.
The ride with the standard suspension is comfortable, but the Denali trim's electromagnetic suspension dampers provide a more composed ride.
Handling is relatively ponderous but safe.
The enormous cabin is quiet, and the controls are easy to use, except for the tricky gear selector.
It's a big step up to get into the Yukon XL, and the tall hood hurts forward visibility.
FCW, and AEB with pedestrian detection, are standard, but BSW is optional.
