We had the opportunity to test this Sierra AT4X in the city, highway and off-road, in the Anza Borrego desert, in California, about 140 miles from Encinitas, California, north of San Diego.

Driving

Although the day before, despite only driving for a couple of hours, we were very satisfied with the new 2022 GMC Sierra Denali Ultimate, the great adventure was with the 2022 Sierra AT4X, a truck with great off-road characteristics, although without sacrificing comfort, luxury, and cargo and towing capabilities.

Despite its 32-inch tires, on the road it showed a serene and quiet ride. It is very comfortable and great for long trips. It was a pleasure to drive on those mountain roads, with many curves and counter-curves. The AT4X always held its own, even in the tightest of corners.

But although I was very satisfied with the road test, what I liked the most was the off-road performance, on sand and roads with very deep potholes, rocks and other surprises of a rough road, where the Multimac shock absorbers had to work much.

While it was fun driving on sandy roads, it was even more so during the ups and downs over some rocky sections, especially at the place called Diablo Drop Off, where the incline is very steep and the potholes are very deep. At all times the AT4X showed composure. Of course, before starting the off-road course, the GMC technicians deflated the tires a little, to improve traction, otherwise it is very difficult to drive in this type of terrain.

We ran this test at Diablo Drop Off with the Terrain drive mode, low gear on the transfer case, and both axles locked. There also this Sierra AT4X showed all its virtues, without disappointing us.

To get back to the road we went back through another path, although the same type, sandy, with potholes, some deep and also rocks, although the path was much more winding and we had to go through some very narrow passages between clay walls and rocks. An experience like few others and very fun!

This AT4X is so much more than the AT4 when it comes to off-roading. GMC designers and engineers did a terrific job creating this vehicle.
