TOKYO — Recent tough financial situations for U.S. top carmakers have resulted from their failures to focus on what consumers truly want, the head of German automaker BMW said Tuesday. Chairman Helmut Panke said that now is not the time when carmakers can survive only by concentrating on their products, without serving users' likes and interests. "A consumer wants to be basically sure that he or she gets a right product," Panke said in a luncheon at the Foreign Correspondents' Club of Japan in Tokyo. He also said some German and Japanese carmakers have successfully increased their shares in the U.S. market by bringing in difference, quality, reliability and lower prices than those set by the U.S. Big Three auto giants.
