Now in its fifth year in production, the Mazda 3 continues to show that you don't have to pay a lot to own a sport sedan. Available in stylish hatchback and sedan body styles, the 3 brings a lot to the table in terms of driving excitement and available luxury features while also providing the roominess and thrift expected from today's economy cars. If a sporty drive and getting a lot for your hard-earned cash are top buying priorities, the Mazda 3 should be at the top of your test-drive list.There are two engines available with the 3, a 140-horsepower four-cylinder in i trim levels and a more powerful 156-hp version in s trim levels. The hatchback, or five-door, is available only with the larger power plant. Both of these engines are smooth and punchy and provide the 3 with plenty of giddy-up -- particularly with the larger 2.3-liter. Neither returns particularly good fuel economy, though, with the Honda Civic besting the Mazda in this regard by about 10 mpg both in the city and on the highway. Mileage is, however, on par with other sporty compact cars like the Subaru Impreza and Mitsubishi Lancer.
