A Detailed Look At Each Member of The Family

  • Rugged luxury is the best way to sum up the new GMC AT4 lineup.
  • AT4 models receive special suspension and drivetrain treatments.
  • We take a look at what is included in each individual AT4 model.

From 2020 onward, the AT4 trim is now available across GMC’s portfolio of trucks and SUVs. The AT4 trim is for buyers who, for a premium, want both luxury and genuine off-road abilities. However, the price doesn’t seem to matter much. More than 80 percent of the vehicles sold by General Motors in the first quarter of 2019 comprised of pickup trucks, crossovers, and SUVs.

Additionally, more than 96 percent of GMC Sierra buyers chose the more expensive and higher-end trims. Sierra sales were up 14 percent year-over-year in 2019, and AT4 played a huge role in that growth. Based on initial Sierra AT4 buyer data, they are affluent, active, and younger than the average truck buyer.

“AT4 continues GMC’s bold entrance into the premium, off-road and adventure-oriented truck and SUV space,” said Phil Brook, Vice President of GMC Marketing. “For each of the AT4 variants, we listened to our customers and made sure the vehicles met their active lifestyle needs.”

What Is The GMC AT4 Lineup?

GMC is simply answering to the laws of demand by making the AT4 trim level more available. What started out as an initiative to glam up the Sierra with rugged off-road components has now become an option across the board.

Along with special off-road treatments, the usage of black chrome is a core AT4 design element. Across the lineup, we see black chrome grilles, fog light surrounds, and rear appliques. On the inside, GMC AT4 models receive aluminum interior decor and premium fabric colors.

The GMC AT4 lineup consists of the Sierra 1500, Sierra HD, Canyon, Yukon, Acadia, and Terrain. Below is a look at each individual model with the AT4 treatments.

GMC Canyon AT4

In the same way the Sierra AT4 attracted new buyers like bees to honey, we’re expecting the Canyon AT4 to become equally as desirable when it hits the market this spring. GMC started the year by announcing an all-new AT4 trim for the 2021 Canyon. There are red tow hooks in the front; a larger grille; unique 17-inch wheels and 31-inch Goodyear Wrangler DuraTrec all-terrain tires; and finally, an off-road-tuned suspension to round up the muscular, go-anywhere vibe.

The GMC Canyon AT4 has a standard naturally-aspirated V6 producing 308 horsepower and 275 lb-ft. of torque. The engine is connected to an eight-speed automatic. Interestingly enough, the Canyon AT4 is also available with a 2.8-liter Duramax diesel with a six-speed automatic. Producing 181 horsepower and 369 lb-ft. of torque, this engine is the default choice for a true workhorse truck.

GMC Sierra AT4

The Sierra was first to receive the AT4 treatment for the 2019 model year. The Sierra AT4 features a two-inch suspension lift, Rancho monotube shocks, and a terrain-selectable traction control system with hill descent control. Of course, it also comes with GMC’s MultiPro Tailgate, two-speed transfer case, grabby all-terrain tires, and skid plates galore.

GMC’s now famous carbon fiber bed is also available for the Sierra AT4.

The Sierra AT4 has similar features and equipment to the SLT model, including a 5.3-liter V8 thumping out 355 horsepower and 383 lb-ft. of torque. The motor is connected to an eight-speed automatic and includes a trailer brake controller. In the cab, passengers receive dual-zone climate control, heated and ventilated seats, with heating for the second-row seats as well.

The Sierra AT4 is essentially a luxury truck with the off-road gravitas of a four-legged animal with hooves. Love-struck buyers will come in droves.
