2019 GMC Sierra AT4
This is not teeth rattling, tailbone busting off-roading. This is off-roading that gets you to the middle of the backcountry in luxury, comfort and a whole mess of style. Built off GMC’s Next Generation Sierra, the AT4 adds visual details and functional upgrades like blacked out chrome on the grill and fog lamps, and a standard two-inch lift package.
Four wheel drive is standard here, as is the 5.3 liter V8, with the option to upgrade to a 6.2 liter V8 or their new 3.0 liter inline-6 turbo-diesel. To help when the going gets really rough, the Traction Select System lets you choose preset drive modes that adjust shifting and throttle mapping for different terrains and weather. And while all 2019 Sierras will come with a heads up display, the HUD on the AT4 will also feature an inclinometer, so you know just how crazy that descent really is. Get your AT4 late 2018, then pick somewhere far away to drive it. Learn more at GMC.
