Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,
