Mazda 3 Sedan
Face-lifted with an even more refined exterior and interior, the 2012 Mazda3 also is the first application in North America of Mazda's innovative SKYACTIV fuel-saving and performance-oriented technologies, achieving 40 mpg on the highway. The Mazda3 model is Mazda's best-selling vehicle worldwide and accounts for nearly half of all Mazda sales in the United States, making the vehicle a prime candidate for introducing SKYACTIV to consumers looking for dynamic performance coupled with high fuel efficiency.
"SKYACTIV is not just an engine; it is the next generation of advanced vehicle performance and efficiency," said Jim O'Sullivan, President and CEO, Mazda North American Operations (MNAO). "SKYACTIV embodies Mazda's philosophy of engineering only vehicles that are fun to drive, satisfying to own and environmentally responsible; and there is no better vehicle to start with than the Mazda3, one of the most exciting sport compact cars on the road."
Redesigned for the 2010 model year, the refreshed 2012 Mazda3 is Mazda's first application of SKYACTIV technologies in North America, receiving an all-new SKYACTIV-G gasoline engine as well as the all-new SKYACTIV-Drive six-speed automatic transmission and all-new SKYACTIV-MT six-speed manual transmission. It also features improved sporty driving dynamics, responsive handling and a comfortable cabin space. The exterior design also has been refined to express a bolder stance, alongside new interior appointments creating additional functionality without sacrificing the touch-and-feel quality. Additional safety features complete the package.
In addition to the Mazda3'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).
The 2012 Mazda3 achieves a high compression ratio of 12.0:1 and delivers 155 horsepower at 6,000 rpm and 148 lb-ft of torque at 4,100 rpm. (The PZEV version of this engine sold in California and other states produces 154 hp at 6,000 rpm and 148 lb-ft of torque at 4,100 rpm).
Compared to the current Mazda3 MZR 2.0-liter engine, the maximum power of the SKYACTIV-equipped 2012 Mazda3 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, Mazda3s with SKYACTIV technology excel in dynamic response, further maintaining the Zoom-Zoom idea of oneness between the car and driver.
