2019 GMC Sierra AT4

New York Auto ShowIn advance of the 2018 New York Auto Show, GMC unveiled the Sierra AT4, an off-road-ready variant of its soon-to-be-released 2019 Sierra 1500 pickup truck.

“The Sierra AT4 is designed for the customer who wants an elevated presence on the road and the ability to venture off life’s beaten path,” said GMC Vice President Duncan Aldred.

The AT4 features standard 4WD with a 2-speed transfer case, a locking rear differential, hill descent control, skid plates, and heavy-duty Rancho-brand monotube shock absorbers, as well as standard 18-inch alloy wheels (20-inch wheels are optional). The AT4 chassis will be set up to provide an additional two inches of ground clearance.

Available AT4 options include GMC’s new CarbonPro lightweight carbon-fiber bed and MultiPro tailgate—a unique configurable tailgate that features six functions and positions for various tasks.

The standard powertrain is a 5.3-liter V8 mated to an 8-speed automatic transmission. A 6.2-liter V8 and 3.0-liter “Duramax” turbodiesel with be available, both of which will pair with a 10-speed automatic.

Sierra is the first GMC to feature the AT4 trim level, though the brand promises to make it available on every model in its lineup.

CG Says:

With the 2019 redesign, GMC intends to put more price and content distance between Sierra and its mechanical cousin, the Chevrolet Silverado. That said, the AT4 feels like a parallel offering to Chevy’s LT Trailboss trim level—and that’s fine with us.

The rival Ram 1500 pickup has enjoyed sales success with its recently introduced Rebel trim level, which closely parallels the equipment GMC is making available in the AT4 bundle. We seriously doubt that many Sierra AT4s will find their way off-road, but we appreciate what a model like this can do for the Sierra’s tough-truck image. Expect the AT4 to sell well.
