2025 Yukon Xl Elevation Review. The at4 ultimate is the new addition to the yukon lineup, replacing the sle and slt options from prior years. For 2025, the yukon boasts improved efficiency and handling, along with an exciting new at4 ultimate trim that's sure to turn heads.

Gmc also makes the elevation the base model and moves out the sle and slt to make room for bigger and better things on the yukon’s debut trim. Including destination charge, it arrives with a manufacturer’s suggested retail price.
