The engineers call this space "the 80-by-120;" it's the largest wind tunnel on the planet, 80 feet tall and 120 feet wide, big enough to hold a Boeing 737, the star of the National Full-Scale Aerodynamics Complex in Mountain View, California. The truck is Navistar's "Catalist," a concept built to cut drag and boost fuel efficiency. The 80-by-120 is one of the few places that can really put the new design to the test.
