2021 GMC Acadia AT4 Front View


If you’re shopping for a new GMC vehicle in the New Orleans area, you might have come across a few vehicles with AT4 variants. But what does AT4 mean? In short, it’s an enhanced version of certain GMC vehicles such as the Sierra or Yukon, that offers extra luxury as well as extra off-roading capability. AT4 vehicles are ideal for drivers who are looking for a little bit extra when it comes to their off-road vehicle, whether you’re taking it through rough terrain on a weekend adventure or through inclement weather on a long road trip. Crown Buick GMC has everything you need to know about the six GMC AT4 vehicles and their unique features in the guide below.



GMC AT4 Vehicle Lineup

With six available AT4 vehicles as of 2022, there’s no shortage of options for Kenner drivers looking for a luxurious off-roader. We’ve got the details on all six AT4 vehicles – the Sierra 1500, Sierra HD, Yukon, Canyon, Acadia, and all-new Terrain – below.

GMC Sierra HD AT4

The GMC Sierra heavy-duty pickup trucks were the first to get the AT4 treatment, adding extra luxury to the exterior and interior while maintaining the strong off-road capability that GMC is famous for. Specs and features of the GMC Sierra 2500 AT4 and 3500 AT4 include:

  • Maximum towing capacity of more than 21,000 pounds
  • Heated leather-wrapped steering wheel
  • Embroidered AT4 accents inside the cabin
  • Luxurious black chrome exterior accents

GMC Sierra 1500 AT4

  • Maximum towing capacity of 9,000 pounds
  • Heated leather-wrapped steering wheel
  • Six-function MultiPro tailgate
  • Factory-installed 2-inch suspension lift

GMC Terrain AT4

The first-ever GMC Terrain AT4 is a compact SUV with seating for five, that doesn’t sacrifice capability for its smaller frame. Here’s some of what you can expect:
