History

The Denali nameplate started as the top-of-the-line version of the GMC Yukon for the 1999 model year. It was also GM's first attempt to go after sales from the new-for-1998 Lincoln Navigator. At the time of its introduction. General Motors decided to give Cadillac its own luxury SUV so the Denali's exterior was shared with the 1999 Cadillac Escalade, with only the front fascia and lower side body panels differing from the standard Yukon. Although the Yukon was redesigned alongside the Chevrolet Suburban and Chevrolet Tahoe in 2000, the Yukon Denali, Escalade, and Tahoe Limited/Z71 retained their GMT400 base design.

The "Denali" brand was derived from the native Alaskan Athabaskans / Koyukon people's name for the tallest mountain in North America. It is also the name of the Denali National Park and Preserve that surrounds the mountain, as well as Denali State Park.
