Mitsubishi Motors Corp. is getting a new flagship luxury model that could--in Japan at least--be a successor to the Diamante sedan that was killed off in 2004. Under an agreement announced Sept. 22, Mitsubishi will start selling a rebadged version of the Nissan Fuga sedan--known in the United States as the Infiniti M--in Japan next summer. Mitsubishi said it is not considering selling the vehicle overseas. It also declined to say what the car would be called or what the company's sales target is. As part of the agreement, the two companies have also begun negotiations about Nissan receiving a version of Mitsubishi's Minicab-MiEV all-electric commercial minivan. The deal is just the latest between Mitsubishi and Nissan Motor Co.--the companies signed a cooperation agreement in December 2010. Nissan has already agreed to provide its NV200 Vanette compact van to Mitsubishi, and the two companies formed a joint venture to make mini vehicles for Japan's domestic market.
