I drive it on the highway at a constant speed of about 78 with the cruise control on, for my daily commute . Very little traffic on my commute, and speed limit is 70. I get about 33 mpg, or 380 miles per tank. I've found that long-range runs of an hour or more seems to burn out the gunk, and I have better fuel economy for the next week or two. I figure driving near 80 is killing the advertised 39 mpg with the Skyactiv engine.

While reviews are mixed, the Skyactiv engine delivers as promised for me. With over 70% city/suburb driving, I've yet to average under 30mpg (odo/pump). Set the cruise control at 65-70 and > 40mpg is easy on a flat highway.

This car does very well.. I drive mostly highway during the week, but a lot of rush hour driving means lots of stop and go. Even with that and the around town driving I do on the weekends, I am still averaging 38.1 MPG!

Hard to beat 40 mpg in a car that drives as well and has the performance of the Mazda3. Most ZOOM ZOOM for the price of any car I test drove.

It sucks (literally). Slightly better than 25 mpg overall (I am driving one with a bigger engine). The 3 i variant would do better without much sacrafaces. But the rating is still below Civics and Corollas of the world.

Fuel economy in the VW GTI is slightly better than the Mazda 3, but it requires premium fuel. In the end, it's about even.
