Mazda will be coming out with a range of fuel-efficient vehicles in 2011. The Japanese manufacturer aims to improve fuel efficiency across its product lineup by as much as 30% by 2015.
Mazda is reportedly focusing on four-cylinder and rotary engines. However, Mazda has not revealed which models would be powered by improved powertrains.
While previous reports speculate that the redesigned MX-5 convertible and Mazda5 will receive the greener engine, Seita Kanai, head of Mazda Motor Corp.'s R&D division, counters that the entire range would be provided new engines by 2015.
The 2.0-liter four-cylinder engine offers a mileage increase of 10 mpg to 32 mpg in city conditions. Highway fuel consumption will go as high as 42 mpg, compared to 32 at this time, when mated to a six-speed automatic transmission.
Expected to bring fuel efficiency up by 30% are rotary engines that also contribute to lowering the final weight of the vehicle. Mazda shares its plan on how to achieve its fuel efficiency improvement ratings. First, the company will develop improved gasoline and diesel engines.
Second, it will focus on more fuel-efficient transmissions, which when connected to upgraded engines, are capable of reducing fuel consumption and CO2 emissions.
Third, Mazda will produce a series of idle-stop and regenerating braking systems that would automatically idle the car when it's not in motion.
