What Was the Diet the 14 Silverado and Sierra Were On Again?

The 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 were designed and constructed out of strategically placed lightweight, high-strength steels for improved durability, safety and fuel efficiency. High-strength and ultra-high-strength steels make the Silverado and Sierra?s fully boxed frames and cabs lighter and stronger, helping the trucks deliver the best fuel economy of any V8 pickups ever placed on the American roadway. High-strength and ultra-high-strength steels make up two-thirds of Silverado and Sierra?s cab structures, including A-pillars, B-pillars, rocker panels, roof rails and underbody. High-strength steel is several times stronger than mild steel.
