2022 GMC Sierra 2500: Brash and blocky

Call it bold -- or garish -- but the GMC Sierra 2500 is an unmistakable vehicle.

As in years past, this truck's interior is pretty disappointing.

This 8-inch navigation screen looks almost laughably small in this gigantic truck.

GMC's MultiPro Tailgate is one of the most ingenious pickup-truck innovations to come out in years.

The optional 6.6-liter Duramax diesel delivers 445 horsepower and 910 pound-feet of torque.

Paradoxically, the Sierra's oil-burning engine is extremely potent and an exemplar of refinement.

This truck's bed promises best-in-class cargo volume.

It's a climb getting inside this Sierra.

Bedside steps make it easier to reach items stashed in the towering carbo box.
