2023 GMC Sierra Denali Ultimate and AT4X First Drive: For Those Who Want More
Auto123 gets in a first drive of the 2023 GMC Sierra 2023, in Denali Ultimate and especially AT4X versions.
Carlsbad, CA - The Denali deluxe version accounts for nearly 40 percent of GMC's Sierra sales. As for the AT4 version, it was successful right from its introduction, but some expected more from that variant designed for off-roading. For 2023, GM has addressed the desires of both that crowd and the luxury set by offering models that push the boundaries of both luxury and off-road capability.
In the case of the Sierra Denali Ultimate, GMC simply took all the options that existed on the Denali edition and made them standard and voilà - you get a Denali Ultimate version. The model starts at $93,000 with everything is included. Its engine is the 6.L V8.

After we briefly drove the Ultimate model to see for ourselves the changes it gets, it was on to the X. GMC set up a full-day adventure in the Borrego Desert in California to test the AT4X's capabilities.
