The designers were required to make an outfit made entirely out of the spare parts and raw materials from a Saturn hybrid car. They were told to walk to 142 West 31st Street in Manhattan. After taking an elevator to the roof of the building, they were instructed to collect as much of the recycled car parts from within the parked Saturn vehicles. They had four minutes to collect the materials and one day to complete their outfits. The winner received immunity for the next challenge.
