AUTOS

Bad News Due From GM: General Motors Chairman Robert Stempel is expected to address his company’s 390,000 employees today and deliver more details about cutbacks and losses at the nation’s No. 1 auto maker. On Dec. 18, when Stempel spoke by satellite to GM’s 390,000 employees, he said 74,000 jobs would be cut and 21 plants shut down by 1995. Analysts now say that Stempel is going to reappear with the specifics: $3 billion in losses last year and, possibly, a list of doomed plants. In his earlier speech, Stempel did not specify which plants would be closed. But among them, he said, would be either an Arlington, Tex., factory or the Willow Run assembly plant outside Ypsilanti, Mich. Combined with reports earlier this month from Ford Motor Co. and Chrysler Corp., the Big Three auto makers will have 1991 losses approaching $7 billion, easily their worst year in history.
