"The 2012 MAZDA3 will have the Skyactiv-G 2.0-litre gasoline engine with the Skyactiv-Drive six-speed automatic transmission (or) the Skyactiv-MT six-speed manual transmission mounted onto a current vehicle platform in order to make Mazda's latest technologies available to customers as quickly as possible," this, according to Mazda PR rep Sandra Lemaitre, sets up the unveiling of brand new SkyActiv technology from the Japanese auto maker.¹

Coming soon to Liberty Mazda Suzuki - 1000 East Park Avenue in Libertyville, IL, Mazda's SkyActiv Technology will become the standard of all Mazda cars beginning in 2013.

Mazda has found that most of the energy loss in the 120 year old internal combustion engine model is primarily thermal: via exhaust, cooling system, engine and transmission surfaces. Mazda's SkyActive engine reduces combustion length, weight and internal engine friction. The auto maker also designed pistons with special crowns.

Those initiatives, together with a 4-2-1 exhaust manifold, help this new powerplant move hot gases away from the engine, increasing thermal efficiency. In the end, the driver receives greater torque and possible fuel economy improvements of up to 15%.
