FWIW the numbers and information presented here really don't work for me. I have a 2010 Flex SEL AWD (I know, not the same segment, but bear with me) that can seat 6 of me (5'11" 215) comfortably for long trips without issue. And I still have room for 5-6 overnight bags behind the 3rd row. Works great for my wife and the family. Some people consider it big but, being angular, it looks much larger that it actually feels when driving. I would think that going down in size from the Flex to an Orlando would at least provide two benefits
1. Reduced price (not really, I paid $31k for the Flex, just under $29k for a similarly equipped Orlando)
2. Increase fuel economy (again, not really. In a 75/25 mix of city/highway driving I have averaged 10.8l/100km over 34 000k). That's actual usage, not based on the on-board computer and AWD to boot.
All this plus I can still tow 4200lbs when I need to. The Orlando (and the Mazda5, Rondo, and other compact 6-7 seaters) need to provide a much more significant price or fuel economy advantage to make up for the size and power shortcomings, since the quality and fun-to-drive factors aren't enough on their own. For most of these a small diesel would do that - but then would the purchase price be worth it?
Just my two cents.
