The verdict

What's good

Independent rear suspension gives noticeably smoother ride than Suburban or Tahoe base models
Triple-screen dashboard with augmented-reality navigation is the most advanced in full-size SUVs
16-way massaging front seats and rear captain's chairs standard at this trim
Super Cruise enables true hands-free highway driving including when towing

What's not

6.2L L87 engine recall history — verify production run before purchase
Cargo space behind third row is minimal — less useful than Suburban for haulers
Fuel economy is among the worst in full-size SUV class even for highway use
Lower NHTSA and IIHS scores than similarly priced Ford Expedition

The engine

L87

6.2L V8

GMC's 6.2-liter small-block V8 delivers the deep, effortless torque that defines a full-size American truck — quiet when cruising, muscular when towing, in Denali and AT4X flagships.

A direct descendant of Chevrolet's 1955 small-block, this pushrod V8 pairs old-school simplicity with modern cylinder deactivation and direct injection.

It can run on just four cylinders when cruising to save fuel.
It shares its small-block roots with the Corvette's V8 lineage.
