The 2019 Sierra AT4: GMC’s Off-Road Warrior

2019 Sierra AT4

In the 2019 Sierra AT4, GMC finally has its own off-road specific variant. Don’t get cynical, this isn’t a base model truck with big tires and some aggressive decals. The Sierra AT4 is built, from the ground up, to deliver excellent performance in adverse conditions. And of course, that capability is combined with what makes GMC unique among pickups, genuine luxury features and first-class comfort.

The 2019 Sierra AT4

According to GMC’s vice president Duncan Aldred, “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. It’s also the beginning for the AT4 brand, which will be seen on every vehicle in our lineup in the next two years.” Clearly, the AT4 name will become a counterpart to the Denali badge. Instead of elevated luxury, the AT4 badge will guarantee rugged, off-road performance.

Performance

Sierra AT4 performance starts with the standard 5.3L V8 engine and 10-speed gearbox. Other engines are available, but the standard setup is confident and efficient. It times the shifts well and improves acceleration. You also get a factory 2” suspension lift and Rancho monotube shock absorbers for better performance on tough terrain.

For superior handling and style, GMC’s off-roader comes with standard 18” wheels, but 20” wheels are available. Both sets are exclusive to the Sierra AT4 and feature a unique, machined-face, dark tinted appearance. By default, the AT4 comes with 33” all-terrain tires. However, 33” Goodyear Wrangler mud tires are also available. I would personally recommend the 20” wheels if only for the fact they more naturally fill out the new Sierra’s massive wheel cut-outs.

Multi-Pro

GMC also confirmed that the Sierra AT4 would get the new Multi-Pro tailgate as standard equipment. If you don’t know, the Multi-Pro is the most innovative tailgate ever. You can configure it in six different ways, serving as a standing workstation, load stop, extendable step/bench, and more. For an everyday workmanlike truck, it’s hardly an essential feature. But it helps set the Sierra apart in a tightly contested segment.

Other standard equipment includes:

  • Black chrome exterior accents on fog lamps and grille
  • Body-colour accents on grille surround and bumper
  • Exclusive athletic interior trim elements
  • Red vertical recovery hooks
  • Hill Descent Control
  • Traction Select System

Available Features

If you want to take the Sierra AT4 to the next level, you can add a bunch of advanced features. Take Surround Vision for example. It uses a series of cameras to generate a live image of your surroundings. It makes navigating tight spots easy – extra useful if you’re driving around rocks and trees. There’s the segment-first multicolour HUD. It projects critical vehicle information like speed, fuel level, and more. It’s also customisable, so you can see the information you need without taking your eyes off the road.

With the massive success of the Denali brand, GMC knows better than anyone that high-spec pickups are a veritable goldmine. And while there is stiff competition from off-road specific vehicles like the Ford Raptor, the Sierra AT4 is a really aggressive statement of intent. It will be interesting to see how its combination of rugged performance and premium style resonates with buyers.
