Mazda 3

A light freshening for 2012 includes powertrain tweaks to improve the Mazda3's fuel economy to an impressive 32-mpg overall. This vaulted its road test score to near the top of our small car rankings for the model year. Further, Mazda's SkyActiv 2.0-liter four-cylinder engine delivers smooth and ample performance. An available 2.5-liter four cylinder provides more power, but is less frugal with fuel. Other attributes include agile handling, a supple ride and a well-designed interior with good materials and comfortable seats. On the downside, rear-seat room is tight and road noise is pronounced.
