The verdict

What's good

Extended wheelbase gives third-row legroom that genuine seven-passenger SUVs cannot match
Independent rear suspension dramatically improves ride versus truck-based body-on-frame rivals
Magnetic Ride Control suspension reacts faster to road imperfections than most luxury SUVs
Massive 28-gallon tank means rare fuel stops even on long family road trips

What's not

Reliability has historically lagged Toyota and Ford in long-term owner surveys
Fuel bills are significantly higher than rivals given the V8 appetite
Tall step-in height can be a barrier for elderly or shorter passengers
Rear visibility is limited, requiring heavy reliance on camera systems

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.
