It isn't that it is "so important", it's that I consider it false advertising.

This mazda pure and simple doesn't deliver what it's said to deliver. Its good yes. I'm pleased with it yes. But it won't do what mazda thinks it will in my world regarding mileage. Not like jeep,ford,nissan,infiniti,chevrolet,pontiac would. I am a bit frustrated with that. Had I known the numbers were inflated so grossly, I would have considered other vehicles that this edged out on account of its superior epa ratings. Forester,GLK350, etc
I actually was a little disappointed on CX-5's gas mileage like you do. But in reality the SkyActiv Technology had made great improvement on engine performance and fuel efficiency for Mazda which probably saved them since Ford left. I guess the best way to put it, SkyActiv doesn't do the greatest things Mazda advertised, but it still performed very well comparing to other automakers who use more traditional approach, such as adding turbo charger and using CVT, to achieve the goal of engine performance and fuel economy. At least I'm hoping the SkyActiv Technology should hold up well in longevity due to its simpler design architecture and less add-on device. If you look at the table I created recently between our Mazda CX-5 and Ford Escape, the overall gas mileage on CX-5 from Fuelly is not that far off from EPA ratings. Data from many car magazines and Fuelly have shown as long as the overall real-world MPG is falling a tad above EPA city estimate, that's on par with almost everybody else for the real-world fuel economy! One thing I can't understand was why there are few people getting far worse MPG than average on CX-5 which makes me thinking SA-G engines are having wide swing inconsistency on fuel efficiency.
