LAS VEGAS - Toyota last week told its dealers about plans to introduce two new Prius models by the end of 2012, the Associated Press reported. 

The automaker will expand the Prius brand by introducing a Prius station wagon starting next summer as either a 2011 or 2012 model, dealers told news reporters. A plug-in version of the Prius will also be introduced. 

Toyota discussed these plans at its annual dealers meeting in Las Vegas. However, the automaker has declined to make public any specific product plans.
