Japanese truckmaker Isuzu Motor announced Oct. 25 it plans to withdraw from a joint venture making sport utility vehicles for North America as part of its broader effort to improve its profitability, according to an Associated Press report. Isuzu, which is 48.5 percent owned by U.S. automaker General Motors Corp., said it will sell its entire 49 percent stake in the SUV-making joint venture, Subaru-Isuzu Automotive Inc., to its partner Fuji Heavy Industries, also a GM affiliate. According to AP, the changes are expected to leave Isuzu with a smaller presence in North America, the world's biggest auto market.
