My background - I used to have 1st Gen Mazda 3 2008 sedan (very comfortable ride comparing to the competition even after several years), added 1st Gen Mazda Cx5 to the family (surprisingly less comfortable ride mostly due to noise but more space for growing family), recently replaced my 14 years old M3 with Mazda Cx9 GT 2022 (wow, what a change - comfort, features, engine responsiveness and silence). I was very curious about upcoming new Mazda SUVs - especially Cx 70 but obviously Cx 90 as well at least to compare to current Cx9.
A few things I have noticed from these early videos. The new CX90 is wider - the benefit is probably more room in the front (this is were CX9 lacks although for me, being 6' 1'' it has never been a problem. I can sit in the front just fine with plenty of room for my legs and I can sit behind my sitting position in the 2nd row perfectly fine) and wider trunk space.
Trunk space looks bigger but: looks like the floor is very high and surprisingly there is practically no storage space under the floor - a little compartment and the rest is taken by the tools. Also there is no extra space in the trunk behind the right wheel and no hidden compartment. So I am actually curious from practical perspective how much bigger the trunk space is comparing to the current CX9 (for me personally the trunk space is more than adequate - much easier to pack our camping gear comparing to CX5 - did not lose my rear view this year).
I also noticed that European reviews of CX60 show limited leg room in the 2nd row and unfortunately it seems like there is a similar issue with CX90 - the space for legs does not look much bigger than in the CX9. On the other hand there is more space in the 3rd row but not by much judging from the fact how the reviewers were having hard time to fit their feet behind the 2nd row.
So overall it looks like the car is bigger with more usable space but it does not seem that much bigger than current CX9. Obviously there is a new engine and the new transmission. I don't care for panoramic sunroof, bigger media screen and full digital cluster and majority of the features look similar to the current CX9. I am also not a big fan of this oversized rear end. I like the front but in my opinion CX9 has a nicer profile. I guess Mazda had to make some sacrifices/choices to accommodate more trunk space and more room in the 3rd row for American market.
Now I am eagerly waiting for CX 70 to see if that might be my next future vehicle replacing aging CX 5.
