How does the Chevrolet Silverado ZR2 compare to the GMC Sierra AT4X? These two off-road-focused trucks are similar in many ways, but have a few key differences.
When similarly equipped, these two GM trucks offer the same power and mostly the same equipment, but they offer differences in some areas. Both trucks give you incredible off-road features to tackle some of the toughest terrain. Should you drive the Chevy or the GMC truck? That depends on what you want to get out of your experience in your truck.
Here are some similarities and differences between these pickups.
Some standard GMC items are options for the Chevy
The GMC pickup in the AT4X trim includes a rear camera mirror, head-up display, adaptive cruise control, and a few other items that are optional for the Chevy. This means those items are baked into the price of the GMC but cost an additional $3,600 for the Chevy.
These trucks have almost $6,000 between the prices, which could be a nod in favor of the Chevy. Still, the GMC includes full-grain leather, heated rear outboard seats, a stamped steel front bumper, and the GMC trailering app, which you won’t find in the Silverado.
