Chevrolet unveiled the 2019 Chevrolet Silverado today at an event in Ft. Worth, Texas.   The new Silverado features new, more aerodynamic styling, and will offer a broader range of powertrain options.  While details have not yet been released, expect the 10-Speed automatic co-developed with Ford to be available.   GM will increase its use of mixed materials combining steel and aluminum "in the right place" according to GM.  This is a subtle dig at crosstown rival Ford's all-aluminum body F-150.
