I recently spent a week driving the 2016 GMC Sierra 1500 All Terrain X and in addition to having a list of functional features which make this Sierra among the most capable off-road trucks in the half ton market – the exterior features of the All-Terrain X package makes this the coolest half ton truck GM has offered in the modern era.
Before getting into my review of the GMC Sierra All Terrain X, I should clarify that this is not GM’s answer to the Ford F150 Raptor. The Raptor is a high performance pickup built from the ground up – unique in almost every way from the next nearest model. The Sierra All Terrain X is a premium off-road package applied to the Sierra SLT, so it is not as elaborate of a package as the Raptor, but it is also far less expensive.
