GM Reorganizes Car-Making Units: The shuffling will place Saturn under the same operating group as the rest of the General Motors Corp. small-car operations. The company’s mid-size cars will be aligned with its large luxury car segment. The company said the changes are evolutionary and designed to help the recovering auto maker lower costs further and develop new vehicles more quickly. For Saturn, the restructuring means future models may evolve from other GM divisions and that those vehicles could use many of the same parts used in GM’s other small cars. Company officials downplayed the potential effect on Saturn’s autonomy.
