GMC Denali XT Concept saves 50 percent at the pumps

GMC unveiled a new concept version of their Denali pickup truck today at the Chicago Auto Show. Boasting a 50 percent increase in fuel economy over a comparable machine, the Denali XT Hybrid concept delivers all the usability of a GMC truck while helping owners to visit the fuel pumps less frequently. The muscularly styled concept is labeled by GMC as a hybrid Sport Utility Truck (SUT).
