Former General Electric CEO Jack Welch, now a Fiat strategy consultant, has told Bloomberg Television that European carmakers are facing a "tough time." "The automotive business is tough in Europe right now," Welch said in the interview yesterday. Bloomberg News said his claim was supported by European Automobile Manufacturers Association data showing West European fourth-quarter new commercial-vehicle sales fell 3.1 percent from a year ago because a slowing economy cut demand for movement of goods.
