GMC added the Sierra EV to its lineup for the 2024 model year. This full-size truck has an all-electric powertrain and is sold only in a crew-cab body style with a 5-foot-11-inch cargo bed. It features a midgate that allows drivers to accommodate long pieces of cargo by folding down the rear seats and opening a space between the cabin and the truck bed. The GMC Sierra EV seats five people and features a comprehensive selection of advanced driver-assistance systems.
