Nissan to Cut Back on Parts Use: Japan’s second-largest auto maker said it will save on labor costs by reducing the amount of parts needed in its cars by 30% over the next three to five years. The company said it will design a new model that can be produced with fewer parts. It said it will also try to use the same parts as much as possible in different models. The company declined to say how much the plan was expected to save.
