Quieter -- but no less lively -- is this turbocharged four-banger from Mazda's race and street car tuners. The Mazdaspeed3's relatively tiny engine produces 263 hp and gets the car to 60 mph in 5.6 seconds, but it doesn't scream "conspicuous consumption." Fuel usage is rated at 18 mpg city/25 mpg highway, while the price of admission is only $24,000.
