Mazda website clearly mentions 135.1 cuft and it really feels smaller than the Sorento. A bummer really. How did they manage to come up with the smallest interior with the largest exterior?
First post guys... I have been following this thread for a while as I am considering the CX-9 and other 3-row crossovers/SUVs. I decided to post as I just recently rented a new V6 Sorento this past week on vacation.
I get what you are saying about the Sorento. It sounds like the Kia ticks your most important boxes. It is a good vehicle. It is quiet, comfortable, roomy, and has an engine with adequate power for every-day driving. The infotainment system is simple and efficient. That's about all I liked. The exterior styling is inoffensive but boring. My biggest gripe is that it drove like an absolute boat, especially on the highway. The space and interior utilization is impressive, but that isn't the most important factor (for me). If you need every millimeter of space, buy that Kia.
The reason that I prefer the CX-9 (on first drive) over the Sorento/highlander/pilot is that it drives better than all 3 and gives me enough space. The CX-9 is also the most attractive from a styling perspective to me. The Kia is dead last in that race in my opinion.
Ultimately, I think the Mazda was designed to compromise a bit of interior space to maximize the exterior style's impact. I also think that they intentionally made some design decisions to make the interior feel more car-like which reduced that space. Some, like yourself, would probably call this bad design. I would disagree.
It all comes down to what the most important factors are for the car-buyer. There is no car on this planet that ticks all of my boxes. At this point in my life, the CX-9 checks off a lot of them.
-Dynamic styling
-Good balance of torque and gas mileage.
-Adequate space. (this is the only place that the Kia easily wins)
-Top of class ride and handling
-Interior material quality
-Comfortable and quiet cabin
-Safety
-Bang-for-the-buck
-Adequate reliability and resale (this is where I lean to the pilot and highlander)
I really wish the CX-9 had ventilated seats though!
