The Mazdaspeed3 is a true "hot-hatch", featuring a 263-hp, turbocharged, 2.3-liter four-cylinder engine. To keep all that power under control, it's standard with a new six-speed manual transmission, limited-slip differential, a torque management system, electronic stability and traction control, 18-inch wheels and tires and sport-tuned suspension. Safety features include six airbags, four-wheel anti-lock brakes with brake assist, active anti-whiplash front head restraints and an engine immobilizer system. For those needing more creature comforts, an optional tech package includes a 6-disc BOSE audio system, navigation, satellite radio, advanced keyless entry with push button start and a perimeter alarm. For 2011, the Tech Package adds rain-sensing wipers, LED rear lights and bi-xenon auto on/off headlights with auto leveling and pivoting adaptive system.
