2019-Present Chevrolet Silverado 1500

The latest generation of Silverado trucks gave us a bevy of new engines to play with. While the Gen V V8s remain, there's also a turbocharged 2.7L gas engine and a 3.0L Duramax diesel engine to choose from. Whether you are looking for economy, pulling power, or something to hot rod, the GMTT1XX Silverado has options for you.
