Torque is the twisting force exerted by an engine, and it, rather than horsepower, is the measure of a work truck that needs to keep its engine spinning while carrying gargantuan loads or pulling trailers worthy of husky-voiced commercial narrators. And the 2017 GMC Sierra HD All-Terrain X's 910 lb.-ft. rating tops the Ram Cummins' 900 lb.-ft. and rivals the Ford Super Duty's 925 lb.-ft. rating.

The Sierra's 6.6-liter Duramax turbodiesel V8's horsepower rating is strong too, at 445 hp. Horsepower is torque multiplied by RPM divided by 5252, so diesel engines' peak horsepower tends to lag behind torque ratings because diesels spin at lower RPM than gasoline engines.

This badass engine come wrapped in suitably menacing sheetmetal, as the Sierra HD All-Terrain X wears a body-color grille and blacked-out wheels, bumpers, mirrors, trim and faux rollbar for maximum Darth Vader effect.

There is also serious off-road hardware, like the Z71 suspension package, locking rear differential, and underbody rock shield to protect the truck's running gear. Spray-on bedliner and all-weather floor mats similarly protect the bed and cab from the muck you might throw into it.

“The new Sierra HD All Terrain X’s powerful attitude reflects a popular trend in very capable off-road trucks, executed with a range-topping level of refinement — a combination of attributes GMC has cultivated for years,” said Duncan Aldred, vice president of GMC Sales and Marketing.

Refinement? What's he talking about? Oh, here it is right here: "heated steering wheel." That's good enough for us.
