Mazda3 TurboIf you're looking for refinement in a compact sedan or hatchback, that's the Mazda3's bread and butter. The Mazda3 feels more expensive and more upscale than its price would suggest by using impressive interior materials, sleek exterior styling, and smooth power delivery regardless of engine selection. The standard engine for the Mazda3 is a naturally-aspirated 2.5-liter four-cylinder that only makes 191 horsepower. Not much when you compare it to the Type R. The optional engine, however, is a turbocharged 2.5-liter four-cylinder. It puts out 250 horsepower and 320 lb-ft of torque on 93 octane fuel, or 227 hp and 310 lb-ft of torque on 87 octane fuel.On top of being more powerful than standard models, Mazda3 Turbo models also offer all-wheel drive as standard and interior upgrades like a large 10.25-inch infotainment screen. There's also a Turbo Premium Plus model that adds a rear spoiler, leather seats, a Bose 12-speaker stereo and all sorts of driver safety aids like parking sensors and traffic sign recognition. In hatchback form, the Mazda3 Carbon Turbo is priced at $34,435 (including $1,185 destination fee) while the Turbo Premium Plus starts at just $38,135 (including destination) for the hatchback. No matter what trim you get it in, the Mazda3 Turbo isn't as performance oriented as the Civic Type R, but the Mazda is still a joy to drive. It's comfortable, quiet, and feels luxurious despite its competitive pricing.
