Mazda 3, SKYACTIV Reach New Heights
In addition to the Mazda 3's current MZR 2.0-liter dual-overhead-cam 16-valve four-cylinder engine is the all-new high-efficiency direct-injection SKYACTIV-G 2.0-liter gasoline engine. Mated to a standard SKYACTIV-MT six-speed manual transmission or optional SKYACTIV-Drive six-speed automatic transmission, SKYACTIV will be available in either the sedan or hatchback models. The MZR 2.0-liter engine will continue to be available with the current five-speed manual as standard equipment. MZR 2.0-liter-equipped models also will be available with the current five-speed automatic as an option.
Approximately 4.4 pounds lighter than the current MZR 2.0-liter engine, the SKYACTIV 2.0-liter adopts multi-hole injectors to enhance fuel spray characteristics, along with specially developed piston cavity shapes that ensure a shorter combustion time and suppresses the impact on power and torque from engine knocking. Pumping loss is also decreased by employing dual sequential valve timing (S-VT).
Compared to the current Mazda 3 MZR 2.0-liter engine, the maximum power of the SKYACTIV-equipped 2012 Mazda 3 is increased by approximately five percent (from 148 horsepower at 6,500 rpm) and torque is increased by approximately 10 percent (from 135 lb-ft at 4,500 rpm). With improved torque, coupled with a drive control system that utilizes coordinated controls of the engine and transmission, Mazda 3s with SKYACTIV technology excel in dynamic response, further maintaining the Zoom-Zoom idea of oneness between the car and driver. |
