Aluminum makes an appearance on the Silverado, though it's not as omnipresent as it is on the F-150. Instead, Chevrolet has chosen to use the material for swing panels, such as the doors, hood, and tailgate, while all the fixed panels are still composed of steel. The result is a further 88 pounds of weight savings. Under the new, lighter hood, Chevrolet has confirmed three engines so far. The first two are continuations from the previous-generation truck—5.3- and 6.2-liter V-8s. For 2019, however, the V8 engines have been fitted with Dynamic Fuel Management, which allows them to run on just one cylinder in certain conditions to save gas.
