The Chevrolet Suburban gets a full redesign for the 2021 model year. This year's Suburban shares the same platform as the Chevrolet Silverado 1500. The new platform increases the Suburban's wheelbase and increases its interior space, giving occupants more legroom in the back. The cargo capacity of the 2021 Suburban is more than 20 cubic feet larger than the 2020 model, offering additional storage capacity for all your gear and groceries.
