GM’s 2015MY Full Size SUVs General Motors has launched its new-for-2015MY full size SUVs. While you might wonder why they care about launching these behemoths when the segment has fallen at the hands of expensive gasoline, these are mighty profit generators for the General even at relatively low volumes. Last year, GM launched the pickups upon which these SUVs are based – the Chevrolet Silverado and the GMC Sierra. When they were launched these pickups were criticized because their styling was so evolutionary from their GMT900 predecessors. But, it turns out that GM planners and engineers really know their stuff and the pickups have won kudos for their capability. The Silverado was named the North American Truck of the Year.
