A three-row SUV with seating for up to nine, the 2021 Suburban is the largest vehicle available on Chevrolet's lineup. Let's explore the base trim and highest trim level of this popular family car. A 5.3-liter engine with a V-8 design propels the 2021 Chevy Suburban LS. Incorporating the Dynamic Fuel Management, this naturally aspirated powertrain whips out 355 hp. Powerful enough to deliver up to 420 hp, a 6.2-L engine with the DFM design drives the High Country. Built on the latest EcoTec3 platform, both eight-cylinder engines can burn E15 fuel during combustion. Each Chevy SUV runs on an automatic transmission system, which makes ten distinct gear combinations. A 4WD system with multiple driving modes is available for these full-size models.
