The 2027 Chevrolet Silverado 1500 debuts with a totally new look and an extra helping of new features, like a dash full of screens. The highly configurable full-size truck's existing turbo four and Duramax diesel are joined by new 5.7-liter and 6.6-liter V-8s, but power figures are under wraps.While Chevy hasn't divulged any notable specs, more details and pricing will be revealed before the next-gen Silverado goes on sale at the end of this year.
