Model overview
The GMC Denali nameplate is adopted by GMC on its top-line trucks and SUVs within the range. Automobiles with the Denali trim option are up to 47% more expensive than those of the normal models. Prices vary from $40,000 for GMC Terrain to $80,000 for a top-line Yukon XL Denali.
The Denali nameplate is usually applied as an insignia or status symbol, and in special, is recommended as a less costly option to the Cadillac Escalade. In 2013 were sold more than 70,000 units of the Denali brand, which estimated 20% of GMC's sales, becoming one of GM's most successful sub-brands, all done without any advertising.
The Denali comes standard with a 5.3-liter V8 engine or can be equipped with the optional 3.0-liter diesel engine. It is paired with a six-speed automatic transmission.
