Like a loyal canine, a thrifty sedan can be your best friend
7th Place: Mazda 6 – $2,196
Mazda trims off a little "zoom" from the same 2.3-liter, four-cylinder engine used in the Fusion and ups the mileage. It's only 156 horsepower and 154 lb.-ft. of torque instead of the Ford's 160 and 156 respectively, but good for almost a $100 of gasoline a year. Double wishbone front and multilink rear suspension provide spirited handling. Mileage is the same with either transmission.
