Super Truck
Even James Bond might take notice. The SmarTruck, developed for the U.S. Army by the National Automotive Center and the Integrated Concepts and Research Corporation, serves as a vehicle for testing cutting-edge technologies. The current model incorporates a sophisticated information system, an adjustable air suspension system for varied terrain, and a slanted body style that […]
