I think you'll be pretty close with the hp rating. I'm hoping for 340 or higher, with 380 or higher torque. But we'll see what Mazda does. I'm actually more concerned with how its going to look lol.
I'm thinking that they'll start phasing out the CX-9 shortly after the CX-90 is released, and it will be retired completely once the CX-70 is announced. The CX-9 has been around since 2006 I believe, so after 16 years it's earned it's retirement. I don't think the CX-70 will have 3 rows, but I'm thinking that it'll have about the same cargo capability as the current CX-9.
I'm REALLY hoping they can pull all of this off!! I want Mazda to succeed.
