Subaru on Friday officially launched production of the rear-drive BRZ sports coupe in its Gunma Main Plant factory in Japan. The plant also builds the Toyota version--which will be sold as the Scion FR-S in the United States--as the Toyota 86 in Japan and as the Toyota GT-86 in Europe. We expect the Subaru BRZ and the Scion FR-S to be in U.S. showrooms by May. The Gunma plant used to build minicars for the Japan market. Subaru plans to add the Impreza to the assembly line next year.
