On the outside, the 2017 Silverado 1500 loses three colors while gaining two new ones:
Slate Grey Metallic
Autumn Bronze Metallic
Rounding out the changes to the exterior is the addition of capless fuel fill system as a standard feature across every model and trim level, with the exception of trucks ordered as pickup box delete; those models will continue having the capped fuel fill.
In addition, the 2017 Silverado 1500 gets a new P265/65R18 off-road tire as an option on the 1LT trim and a revised High Country package, which now includes:
Enhanced Driver Alert Package
Power adjustable pedals
Heated leather-wrapped steering wheel
