I would too, but from Mazda's POV it's about what they can sell, not what they can make. Sedan sales across the boards are cratering, so they wouldn't gain much jumping into a losing market.
Even this RWD (will these be available in RWD only?) SUV push is dubious. Most of the stuff in these things' classes are FWD and sell fine. The CX-9's biggest problem was packaging... seems like Mazda thought, "lets change the platforms to justify the bad packaging" vs "lets just fix the bad packaging"
We'll see how it all shakes out... I'm legit curious about the CX-90 PHEV, but only because it's a 3 row PHEV with balls and hopefully decent space, not because it's RWD. The whole thing is so bizarre in a way only Mazda can do.... they never offered the 6 with AWD but they're making RWD crossovers..... headscratching ****.
