It's the latest in engine technology, all thanks to several top engineers and designers at Mazda. The new Skyactiv-G engine is the first of its kind. SKYACTIV is the official name for the powertrain packages that will improve fuel economy and emissions without having to resort to hybridization or related battery-based technologies. Not only will these new engines create increased fuel efficiency, they will also harness more power than ever before. Currently, around 70 percent of the energy contained in fuel is lost within a vehicle's powertrain and fails to be transferred as motive power to its wheels. SKYACTIV is Mazda’s attempt to produce more miles per gallon than conventional gasoline and diesel engines, without resorting to costly hybrid technology. The Skyactiv engines have a world-beating compression ratio of 14.0:1, the highest ever achieved in a petrol engine. According to Mazda, the new SKYACTIV gasonline engine is more efficient, with a 15% increase in torque and 15% reduction in fuel consumption compared to the current 2.0-liter gas engine. The SKYACTIV strategy will also lead to lighter-weight vehicles and engines that produce less friction. Both of these changes will also help the automaker build a new crossover that’s sporty but sips fuel.
The 2012 Mazda3 will receive the first application of Mazda's SKYACTIV technology. This 2.0-liter four-cylinder direct-injection engine makes 155 horsepower and mates to either a 6-speed manual or 6-speed automatic transmission. Available on both the sedan and hatchback models, the engine could produce up to 28 mpg city/40 mpg highway when paired with the automatic, according to Mazda.
Mazda continues to win awards for developing fuel-saving, environmentally-friendly technologies for its cars. Two Mazda engineers were presented with the Outstanding Technical Paper award at the 61st annual Society of Automotive Engineers of Japan (JSAE) presentation. Mazda took home three awards for research that will be used in Mazda's next-generation Skyactiv vehicles Mazda's unique start-stop system, i-stop, and its single-nano technology catalyst and for groundbreaking research into the properties of sound insulation material. Mazda also won the Innovation Award at this year's Fleet World Honours in London.
Together, Mazda promises that SKYACTIV will not only improve the efficiency of gasoline and diesel engines, but it will also uphold the performance and driving dynamics expected in Mazda models.
