With what the Mazda CX-4 has to offer right now and its retail price, there is really no spot left for the CX-4 here in the US but things might be different next year when the 2018 Mazda CX-5 arrives.
We know that the Mazda CX-5 will be coming in with an exterior and interior upgrade but what we do not know if it is going to come in with a bigger price tag. There are rumors saying that Mazda might be thinking about making the Mazda CX-5 into a premium model and if that is the case, the Mazda CX-5 will come with a bigger price tag.
That means there will be a bigger gap between the Mazda CX-5 and the Mazda CX-3. If the gap is big enough, Mazda might even fill it up with the Mazda CX-4 model.
There were also talks about the Mazda CX-5 getting an engine upgrade and that we might see the Mazda CX-9 engine under the hood of the CX-5 but we will have to wait until next year to see if any of these rumors are true.
