The Mazda3 has been on the market for five years already, and yet it doesn't feel old. The S Touring sedan I drove recently could easily be mistaken for a newer entry. The S models have Mazda's 156-hp, 2.3-liter engine, which is a worthwhile upgrade over the 2.0-liter in the Mazda 3 i, even at a cost of a few MPGs. Tied to a five-speed automatic, it accelerates smartly, and sounds pleasant doing so, thanks in part to the presence of twin balance shafts. The cloth upholstery is more handsome than most-leather is an option-and the two-tone beige and black color scheme and gloss black trim is far nicer than the monochrome beige or gray in most small cars. At $21,330 (with a sunroof and satellite radio), the Mazda3 S Touring looks and drives like it costs more.
