Nissan Motor Co. is in talks with U.S. auto-parts maker Delphi Automotive Systems Corp. for a possible deal to sell Nissan's stake in its affiliate supplier Calsonic Kansei Corp., Nissan President Carlos Ghosn said Friday. The Japanese automaker is selling off its suppliers in an effort to cut costs. Under a "revival plan" led by Ghosn, Nissan has been trying to halve its suppliers from about 1,100 companies to less than 600 by fiscal 2002.
