What happens when you take an entry level five-door hatchback and stuff it with a turbocharged four-cylinder? If you guessed Audi A3 or VW SportWagen, you'd be right, but on the wrong continent. Being a list of the Japanese sort, it would mean the Mazdaspeed3. Don't let wagon-esque family disposition fool you, the 'Speed3 is capable of 3G speeds beyond that of AT&T, with a 13.8-second quarter-mile time and 5.3-second 0-60 mph time.
