The automotive world is watching a place called Makuhari Messe today. It’s the home of the biennial Tokyo Motor Show, which is the home show of the Japanese auto industry. And it’s where companies like Nissan, Honda and Toyota roll out their most significant new products. There’ll be everything from microminis to supercars on display. Toyota will show that expensive can also be environmentally friendly, with a gasoline-electric luxury sedan concept dubbed the LF-S. Between them, the various Japanese makers are likely to show as many as 50 or more concept and production vehicles. But underscoring the significance of the Tokyo Motor Show, European and American makers will have a high-profile presence, too. Mercedes calls its F500 a research vehicle. It’s heavy on high-tech, as well as interior space. The trans-Atlantic automaker’s U.S. arm will show up with the 3-seat, fuel cell-powered Treo. Tokyo’s known for wild designs. But expect to see many of the show’s products work their way into production.
