Wow. I already have a 2016 Mazda 3 that gets around 40MPG (even though it's not a hybrid) and it's already pretty peppy.

Probably the best car I've owned, and I've owned several nice sports sedans. Getting 40MPG is too convenient when you make longer commutes, not to mention the thing cost ~20k at 0% APR. Blows any hybrid out of the water for total COO.

Are those imperial gallons or US gallons?

Mazda is one of those companies just don't stop revolutionizing. First they got rotary to be actually usable. Now this.

Did they get the rotary to be usable? I thought even at its best, it was finicky and temperamental. I have never owned or driven one, just doing some idle reading online, so asking this as a serious question.

OK, so honest question: I have a 2012 Mazda 3 which, presumably, gets 40mpg. But I can't realistically get anything above 29mpg on average. Am I just an aggressive driver? :)

[edit] I agree, by the way, that the cars are incredibly fun to drive, for being "fuel efficient."

I can get 40MPG (US) highway with a 2015 Mazda3 and a somewhat aggressive driving style. City is usually low 30s.

The manual transmission is also one of the nicest I've ever driven.

These are great cars.

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 think you are misreading that. The increase of 10-30 percent is in torque, not MPG.
