In 2021, the Chevrolet Suburban gets a full redesign, including a new exterior, a refreshed cabin, and added safety technology. There are six trims offered in the Chevy Suburban family this year. While there are some differences among the trims, they share some similarities, including more legroom and interior space. This gives it a longer wheelbase and 23 additional cubic feet of storage capacity, which provides the Suburban with the most cargo capacity in its class.
