Mazda was projecting 90,000 sales for the CX-90 and 30,000 for the CX-70. Mazda never positioned the CX-70 as a volume seller.I believe Mazda's decision on the CX-70 was based on projected sales volume. There isn't enough sales volume in this segment to justify the cost of any significant changes in the platform.
Honda sells nearly three times as many Pilots (3-row -- about 110,000 units/year) than Passports (2-row -- about 40,000 units). We don't have enough data yet on CX-90 sales, but if you look back at historic Mazda three-row SUV sales (the CX-9), Mazda usually sold around 30,000 units. That would predict that Mazda might sell about 10,000 CX-70's per year. Mazda couldn't justify any significant development costs for a vehicle that will only produce 10k sales/year. OK, maybe we should adjust those numbers upwards somewhat, maybe they'll sell more CX-90's than the old CX-9, but I still think the best-case scenario for the CX-70 is less than 15,000 units/year. That's why it's simply a CX-90 with 3rd row seat delete and some trim changes. They couldn't even justify the cost of shrinking the wheelbase & overall length of the same platform.
