2012 had half Skyactiv and half .. non-Skyactiv. The expected MPG on the non is around 30. You'd have a badge on the rear of the car (if sold in US, at least) that would indicate Skyactiv.
I had the 2012 for a few years. When I was driving 80%+ highway, I would struggle to get below 35MPG or above 42MPG.
On a 50%-50% split, I would be in the mid 30s, usually 36MPG or 37MPG.
When I was 80% city, I would be around 32MPG on average.
That car does not have much low-end torque, so if you accelerate aggressively from stops you can definitely tank the MPG. I didn't see much impact from aggressive acceleration at highway speeds (e.g. going from 30MPH to 70MPH on an on-ramp, or pulling around a slow group of cars going from 45MPH-70+MPH). I did see a lot of impact from flooring it 0-30.
