Ahead of the New York Auto Show, GMC has unveiled the 2019 GMC Sierra AT4, featuring a 2-inch suspension lift, four-wheel drive with a two-speed transfer case, locking rear differential, skid plates and off-road Rancho monotube shocks. Under the hood is the standard-issue 5.3-liter V8, though a more powerful 6.2-liter V8 ore 3.0-liter inline-six Duramax diesel are available, both paired with a 10-speed automatic transmission. The Sierra AT4 rolls on bespoke 18-inch or 20-inch wheels wrapped in all-season tires, with Hill Descent Control as standard. There's also the industry-first MultiPro Tailgate, which can double as a load stop, step ladder and more. Additionally, shoppers choose to include a multicolor head-up display, rear camera mirror and carbon fiber bed.
Look for the Sierra AT4 to come in dark colors, complemented by a grille finished in black chrome. That same dark chrome look continues on the fender trim, as well as the bezels of the LED fog lamps. The window trim, mirror caps and skid are similarly finished in glossy black.
Expect pricing to be announced shortly before the Sierra AT4 launches this fall.
