2014 Silverado Named Most Corrosion-Resistant Chevrolet Truck
To help build on the Chevrolet Silverado’s reputation as a long-lasting full-size pickup, engineers designed the 2014 Silverado to be the most corrosion-resistant Chevrolet truck.
According to GM, 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. At every step of the design and manufacture of the new Silverado, materials and production processes were selected to help minimize deterioration over time.
“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.”
Additional 2014 improvements include improved hem flange sealing on the doors and hood, improved chassis corrosion protection to enhance the appearance and extend the life of underbody components and anti-chip protection on the lower body side.
The months of accelerated testing on the trucks is equivalent to more than 10 years on the road, says GM.
