Sure many commented that people should not expect good FC from D-Segment cars, but with GDi engine I'd think the you can at least expect around 10-11km/ltr for a 2.5ltr version, because that's what I'm able to get as well with my old 2008 car (which is should be even ancient technology compared to this new Mazda 6).
Btw for that size of car with 2.0 engine, I believe it would give worse FC due to underpowered engine pushing a heavy car.

have to agree with the post above... shouldnt the FC of the skyactiv engine be better than average? anyways, will the octane level (RON95 vs RON97) affect the FC for an engine with such high compression ratio? (and it seems the examples given by TS are isolated cases and not everyone have the same issue?)
