What Changed

All GM full-size SUVS are new for 2021 including the Chevrolet Tahoe and the longer wheelbase Suburban. Larger in almost every dimension, the Suburban rides on a 4.1 inch longer wheelbase. The familiar 5.3l V8 (355-hp) and 6.2l V8 (420-hp) return but are now joined by a more efficient 3.0l six-cylinder diesel engine with the same torque rating as the 6.2l. Pricing starts around $53,000 and increases based on trim level and powertrain.
