New or Significantly Altered Models
- 2021 GMC Yukon
- All GM full-size SUVS are new for 2021 including the Yukon and longer wheelbase Yukon XL. Yukon models are larger in almost every dimension, gaining over 4 inches in wheelbase and more than 6 inches in overall length. The familiar 5.3l V8 (355-hp) returns and the 6.2l V8 (420-hp) is available on higher trim levels. The big news is the arrival of a more efficient 3.0l six-cylinder diesel engine with the same torque rating as the 6.2l. Pricing starts around $52,000 and increases based on trim level and powertrain.
