savagegeese's CX-30 review showed some presentation slides from Mazda. If you look at the slide at 19:10, Mazda plans for the CX-30 to basically take a decent chunk from the Mazda 3, Mazda 6, AND CX-3. While the Mazda 6 was suppose to have a sizable overlap with young families, the Mazda 6 in their new strategy is basically only for a single/couple with few or no kids of higher socio-economic class who still want a large sedan. Mazda 3 is planned to take the biggest hit. Small crossovers are what Mazda is banking on.
