2015 Prius said to have even better fuel economy

The next Toyota Prius will get “significantly better fuel economy in a more compact package that is lighter weight and lower cost,” according to Satoshi Ogiso, the Prius program's chief engineer.

He said Toyota is looking at improving miles per gallon to 55, compared with today's 50 mpg and that the next-generation Prius electric motors will be smaller and more powerful; in addition, its gasoline engine will be among the world's most efficient.
