DETROIT — General Motors is giving its big pickups a much-needed makeover. It unveiled new versions of the top-selling Chevrolet Silverado and GMC Sierra on Thursday and aims to get them to showrooms by early summer.
Truck sales are rising after a five-year slump. And the new pickups replace models last revamped in 2007. That means GM dealers are offering pickups that are dated compared with newer Fords and Rams, hurting sales.
