The 2021 GMC Acadia is offered in five trim levels: SL, SLE, SLT, AT4, and the Denali, with 5-, 6- and 7-passenger configurations available.
Adding 4WD to any grade — except the SL (on which it’s not available) and the AT4 (on which it’s standard) — increases the bottom line by $2,000 or $2,400 depending on model.
