The GMC Sierra AT4 marks the debut of a new off-road-centric premium trim package for GMC, AT4. As with its ultimate luxury package, Denali, GMC plans to proliferate AT4 to all its models.

As a truck-only brand, GMC feels that it is in the unique position of being able to marry luxury with serious off-road capability.

“The 2019 Sierra AT4 is designed for the customer who wants an elevated presence on the road and the capability to venture off life’s beaten path,” said Duncan Aldred, vice president of Global GMC.

All AT4s will feature standard four-wheel drive with a two-speed transfer case, locking rear differential and skid plates. The Sierra also gets a two-inch lift kit, standard 18-inch wheels with Goodyear Wrangler Duratrac tires and Rancho mono tube off-road shocks.

Options include an upgrade from the standard 5.3-liter small block V8 to a 6.2-liter V8 or the Duramax 3.0-liter inline six-cylinder diesel.

And, obviously, there are changes to the Sierra’s appearance too. That means body-color bumpers, black chrome trim and the obligatory contrasting red tow hooks.

The cab gets the incongruous combination of leather seats and all-weather floor mats, so you’ll be coddled while plopping muddy boots on the floor mats.

“The 2019 Sierra is the boldest expression ever for GMC’s full-size pickup, and the new AT4 reinforces its essence of capability with distinctive, athletic cues,” said Matt Noone, director of design, GMC Exteriors.

The GMC Sierra AT4 goes on sale this fall, just in time to let you be a hero in next winter’s bomb cyclone blizzards.
