Denali or Denali Ultimate?
The regular Denali already gives shoppers the Sierra’s Denali design, premium interior materials, power front seats and standard V8 power.
Denali Ultimate puts several upgrades into the standard equipment list, especially Super Cruise, the 6.2L V8, massaging front seats, full-grain leather and the 12-speaker Bose system.
When comparing actual trucks, check the equipment on the specific vehicle rather than assuming every Denali is configured the same way.
