Sky Tech Improves Economy/Emissions by ANOTHER 30%
Mazda - Mazda tips further fuel savings | GoAuto
MAZDA has set a target of another 30 per cent drop in fuel use and emissions within five years under its SkyActiv technology program.
The company’s vice-president of European research and development, Ichiro Hirose, told Australian media including GoAuto at last week’s Paris motor show it was possible to achieve this improvement.
“Next generation technologies should deliver an additional 30 per cent improvement,” he said.
“Our target is approximately five years or so, maybe quicker than that.”

I'm guessing they are figuring out quite a bit with their super capacitor tech. Maybe they have found a way to get piston engines up to 18:1 CR or something, but I think 'hybrid' type of technology is more likely here.

I fear we will soon find ourselves in a place where emissions and mpg become the focal point of all cars and the zoom zoom is but a distant memory.

or actually more the case is that the two engines are optimized differently. the diesel is low compression with a carefully managed combustion so it can be lighter (aluminum block) without sacrificing HP.
with the gas engine they found that reducing the "internal" egr effect (like they did with the Renesis) lets them run higher compression and have higher efficiency.
its very good out of the box thinking and optimization of the designs.

I would like to see the compression ratio for the new SkyA's for the NA market, as we have inferior fuel (hence our lower 13:1 SkyA-G's).
Until this day, I have been trying to figure out the dynamic compression ratio of the current SkyA engines. Everything given is static CR, unfortunately it changes as the engines are running an Atkinson cycle. There is a way to calculate the DCR, but not enough valve lift info is given.

It would be stupid for Mazda to build boring econoboxes because zoom-zoom is what separates them from everyone else.
