GMC unveiled the Denali XT concept at the 2008 Chicago Auto Show. It offers a 50-percent increase in combined fuel economy over comparable small pickup trucks when running on gasoline, and it incorporates a new, muscular form in a performance-styled, hybrid sport-utility truck (SUT).
The Denali XT has a unibody architecture and rear-wheel drive, enabling its distinctive design and efficient performance. It builds on the equity of the Denali line and its reputation for advanced engineering and refinement, including the first combination of GM’s two-mode hybrid system with an E85 ethanol-capable engine. Denali XT’s new, more efficient 4.9L version of GM’s small-block V-8 features fuel-saving technologies such as direct-injection technology and Active Fuel Management.
The engine is matched with GM’s unique two-mode hybrid propulsion system, giving the powerful SUT exceptional fuel economy and uncompromising capability.
