What is GMC's AT4 range?

A few years ago, GMC introduced a first model bearing the letters AT4. It was with the Sierra van and from then on, we knew that the idea would make little ones.

And what is this idea? To offer additional tools to a given vehicle to allow it to venture a little further than usual off the beaten track.

Today, the appellation has toured the range. However, what does it really consist of? Let's go around the question.

The trucks

Along with the pickups in the family, the modifications enjoyed by the AT4 models are impressive. Both the Canyon and the Sierra feature oversized Wrangler Duratrac tires. As an option with the Sierra, Wrangler Territory are even available. And we're not just talking about competent off-road tires; they are mounted on unique rims which add to the beauty and character of the models.

Under the body, the Canyon has an automatic locking rear differential, a two-speed transfer case, a suspension tuned for off-road driving, as well as hooks in the front to tie down and tow loads. Interestingly, the Canyon AT4 model is offered with cloth or leather seats, depending on your taste. The seats are also exclusive to this version. Under the hood, the 3.6-liter V6 or the 2.8-liter 4-cylinder diesel are possible.

In the case of the Sierra model, the big difference is the two-inch suspension raise, which has a direct effect on the look of the model. A two-speed transfer case, off-road suspension with Rancho monotube shock absorbers, underbody skid plates and the Traction Select terrain management system are also included, as are wheel hooks. 'before. Either the 6.2-litre V8 or the 3-litre diesel engine are available.

Really, very interesting capacities for these two models.

SUV's

With a massive model like the Yukon, we did something striking and interesting, which was to revise the front fascia to increase the angle of attack, now at 32 degrees. Improved abilities and a killer look!

Otherwise, the model benefits from off-road tires, black chrome trim and the distinctive design of the AT4 approach. Both V8s are offered with this version (5.3 and 6.2 litres).

In the case of the Terrain model, we note the presence of skid plates, exclusive all-terrain tires and the Traction Select system. The engine chosen is the 1.5-litre 4-cylinder turbo. For its part, the Acadia also benefits from unique wheels and tires for off-road driving, as well as the Traction Select system. Its mechanics is the 3.6-liter V6.

In short, the modifications are adapted to the needs that you have according to the type of vehicle that you are looking for. The AT4 models in the range are also very popular, because they offer that little extra you expect from a so-called utility vehicle. A discovery is essential if it has not already been done.
