Mazda sky engine

Is the sky engine going in the 2011 Mazda 3? And, if so, when will it be released?

No it is not. The engines for the 2011 Mazda 3 are the 2.0L for the base model, 2.5L for the “i” model, and the 2.3L Turbo for the Mazdaspeed model. There are diesels if you live in Europe and are a belt-and-suspenders kind of guy. The rumors are that the Miata will be the first car to get the sky engine. I don’t know if it’s happening though.
