The 2021 Suburban is notably larger, with more cargo and passenger space. It seats up to nine in this three-row large SUV, with an optional front-row bench seat on the LS trim. Second-row bucket seats in the Premier trim drops capacity to seven passengers. Its second and third rows have a couple more inches of legroom, and the cargo area expands by 23 cubic feet, having 145 total cubic feet. Its new independent rear suspension and design make the load floor flatter and lower. The Suburban also gets sliding second-row seats for the first time, and an optional power-folding functionality for the rear seats that can be controlled from multiple places inside the SUV.
