I bet the extra cog helps significantly.
Next generation Mazda5 needs:
1. 2.5L Skyactiv engine
2. 6-speed Skyactiv AT
3. 3 more inches of front leg room AND 3 more inches of cargo space behind 3rd row
4. SAT-NAV Infotainment option
and I think it would be one of the best cars for its intended purpose...a great people mover that's not big and bulky with decent power and great fuel economy.
That would put it closer to $30k and it wouldn't sell, probably the same reason why Ford cancelled the Grand C-MAX.
