2014 Chevy Silverado Z71

Trucks are supposed to be tough and more than half of light-duty pickup trucks on the road are now 11 years or older.

To improve the toughness of its truck brand, Chevy engineers have designed the 2014 Silverado to be the most corrosionresistant Chevrolet truck ever.

“Silverado’s corrosion protection measures provide superior defense against elements in the environment, whether driving through farm fields, on construction gravel, or down a snow-covered highway,” said Mark Yergin, Engineering Group manager, General Motors Corrosion Engineering and Labs.

“The new Silverado is our strongest truck yet, affording us the confidence that the truck will continue to meet customers’ needs throughout its life.”

The 2014 Silverado starts with zinc-coated (galvanized) steel for the roof and all body panels except the hood, which is made of an aluminum alloy that reduces weight and provides corrosion resistance, Yergin said. At every step of the design and manufacture of the new Silverado materials and production processes were selected to help minimize deterioration over time. Additional 2014 improvements over previous models include anti-chip protection on the lower body side for extra protection from stones or gravel.

The effectiveness of these changes was borne out during extensive proving ground testing at exposure levels higher than most drivers ever experience, Yergin said. The months of accelerated testing these trucks undergo is equivalent to more than 10 years on the road, he added.

Post-test evaluations of the trucks, including the search for and elimination of corrosion even on areas of parts customers never see, helps ensure the overall vehicle performance, Yergin said.
