Mazda originally performance: The EPA estimates fuel economy at 21 mpg city/30 highway and 24 mpg in combined driving for the four-cylinder engine running through the five-speed automatic. Models with the manual transmission are expected to achieve 1 mpg less overall. These figures are competitive among midsize sedans, but opting for the V6 will yield only 17 mpg city/25 highway and 20 combined, which is at the low end for this segment.
