Like athletes who burn fat and build muscle to become more competitive, the 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 strategically replaced traditional steel with lightweight, high-strength steels for improved capability, 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 V-8 pickup, up to 23 mpg highway. They also have class-leading towing capability of up to 12,000 pounds when equipped with the available 6.2L V-8.

Similarly, making the most of mass also enables Silverados and Sierras equipped with the 4.3L V-6 to tow up to 7,600 pounds, the highest for any standard V-6 in the segment, with EPA highway fuel economy of up to 24 mpg.
