Ford Motor Co. opened a new 155-acre manufacturing campus in Chicago for 12 Ford automotive suppliers. The state of Illinois gave Ford $5.7 million in tax breaks to expand the 80-year-old operation. The $250 million suppliers' campus will create more than 1,400 new jobs. Ford also will add workers at its Chicago Assembly Plant, where the 2004 Ford Five Hundred, Ford Freestyle and Mercury Montego will be built on a single platform. The plant can build eight models based on two platforms and will save $50 in freight and transportation for each vehicle built. The suppliers will share 1.5 million square feet of manufacturing and office space in four multi-tenant buildings located one-half mile from the assembly plant.
