( http://www.TFLcar.com ) The 2012 Toyota Prius C gets the highest MPG in the city in America of any vehicle on the road that does not have a plug. At 53 city MPG the smallest of the new Prius line sips fuel to make the most of every gallon. We recently had the chance to get to know the new Prius C to find out what makes it tick and just how it manages to get such high mileage in the city.
