Mazdaspeed6

The 274-horsepower, 280 lb-ft of torque, all-wheel drive MAZDASPEED6 is expected to add additional customer and media accolades to the MAZDA6 family's already impressive collection. Power from the direct-injection turbocharged 2.3-liter engine is chanelled to an all-new Active Torque Split All-Wheel Drive system for traction and handling in all conditions.The performance attitude of the MAZDASPEED6 stems from its powerplant. By introducing direct injection to a turbo application, Mazda circumvented the usual drawback of turbocharging poor low- and mid-range torque - while meeting strict exhaust regulations. Both fuel mixture loading efficiency and torque are increased by injecting fuel directly into the combustion chamber. As a result, the turbocharger delivers much of its 15.6 psi of boost from approximately 2500 rpm.
