Like the exterior, the trucks' interiors aren't enormously changed in appearance from the current versions, but the overall quality and feel have been improved.
"Truck owners want a well-crafted cabin, but also one that still feels like a truck," said Helen Emsley, Sierra interior design director , said in GM's announcement. "They want a purposeful interior, not one that's flowing like you'd find in a car or crossover."
Among the changes are bigger knobs that are easier to use with work gloves. The trucks will also have a new version of GM's IntelliLink system for interacting with cell phones and entertainment.
The 575-hp Shelby Raptor has monster performance and rugged off-road capability, making it a pick-up truck for the not-so-faint-of-heart.
