Inspired by the American Super Chief railroad trains of the nation’s past, the bold Ford F-250 Super Chief concept truck came equipped with a supercharged V-10. Engineered to run for 500 miles between fill-ups, the Super Chief power plant could operate on hydrogen, E85 ethanol or gasoline. The F-250 Super Chief's locomotive-inspired front appearance and imposing grille set the tone for the exterior styling. Overhead, the entire roof was glass, bisected by a leather-wrapped grid of American walnut and the leather in the cabin was Spinneybeck, aniline-dyed in a rich brown. Public reaction to the Super Chief during the Chicago show allowed Ford to gauge future trends for stylish and rugged high-end trucks.
