Like every automaker thats worth its salt, Toyotas bottom line is the most important thing the company has to take care of. And, with the U.S. car market experiencing a shift in demand the likes of which we havent seen in a long time, the Japanese automaker is in the process of reviewing its entire U.S. lineup with the possibility of dumping nameplates or models that have become sales anchors on the market. A final decision isnt expected to happen soon, but with the U.S. auto market getting dominated by SUVs and pickup trucks, Toyotas model lineup could experience a dramatic shake-up in the near future.
