The article contains a mistake about the mpg rating of the Fiesta. The author states that "Toyota Prius, with 51 miles/gallon fuel efficiency burns 196 gallons per 10,000 miles driven, while the Fiesta burns 250 gallons over the same distance."
However, if the Fiesta consumes 250 gallons over 10,000 miles, that is equivalent to 40 mpg (just divide 10,000 miles by 250 gallons).
The combined mpg rating of the Fiesta is 33mpg (automatic or manual transmission) as listed for instance at the government's official website fueleconomy.gov.
