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. Denali XT's 4.9-liter version of GM's small-block V-8 features fuel-saving technologies such as direct-injection technology and Active Fuel Management. The vehicle combines GM's two-mode hybrid system with an E85 ethanol-capable engine.
