The 3-door or 5-door Yaris Liftback, formerly known as the Yaris, takes a little old-school approach to the compact hatchback with enough power, medium fuel economy and decent yet not excellent driving comfort.The Prius C’s key point of sale is the fuel economy of 46 mpg. With the 1.5 liter four-cylinder and electric engines, which combine for 99 hp, the Prius C is neither fast nor enjoyable to ride (unless you want the best fuel efficiency). The front seat is comfortable enough and the cargo area has lots of space.
