2007 CX9 MPG by haymista
Feb 25, 2008 (5:50 pm)

I have an 07 FWD and 95% of my driving is short trips in city conditions. I got 16.7 mpg on my last tank, and I was pleased. I did not need to run the a/c or heat much so that probably helped as most tanks have been around 16.0. I have only had 1 highway trip and I got 20 mpg. I have somewhat of a heavy foot, although I don't punch it.

I am on my fourth tank now and it looks like it will be in the neighborhood of 15 MPG again. I got 16.4 and 15.4 on my last two tanks with about 40% highway. I give a little lenience to the fact that I live in hilly terrain, but I still expected better mileage than this. I gave up a V8 Explorer that was much quicker off the line and got nearly the same mileage as my CX-9. I really love this car, but the mileage could prevent me from getting another one when my lease is up in less than 26 months!

any hope for new diesel or a hybrid by jreddick

I am really looking at getting a mazda CX9 (or competing vehicle) in another year to 18 months. The familys growing and the utility factor is two appealing. However, obviously gas prices are a concern. I would really like to purchase a nicely loaded vehicle that was safe and reliable and drive it into the ground. However, at 15 or 16 mpg it might put me in the ground instead!
 
Anyone know if there are going to be any diesel or hybrid (or, praise be, diesel hybrids) coming down the pike in this or any of the competing vehicles? Maybe Im just being picky, but it doesn't seem that implausble to have these type vehicles average in the low to mid 20's... I could totally justify getting one then.

The CX-9 is rumored to be getting a direct injection engine, which should bump gas mpg by a couple of points. Haven't heard anything about a hybrid.
 
As far as competing vehicles, the Highlander has a hybrid, but doesn't really have the same 3rd row space and cargo. The thing will get about 24 mpg city and hwy, though. Also, the upcoming Chevy Traverse is getting a direct injection engine, and might have a hybrid, but probably not for a couple of years.
 
Unfortunately, I haven't found anything that gets decent mileage with AWD. I chose the CX-9 because of handling and ride, certainly not for 21 mpg hwy...

MPG at 1600 miles by kenmarc

Only 1600 miles so far, we are averaging 15.8 to 16.8, 90% city driving. For comparison, our 04 Pilot was always 18-19 in the same conditions, from day one.
 
We will be taking some road trips this summer, hoping I see 20+.

Diesels are looking less and less attractive. Granted they get better fuel mileage but the price of diesel is skyrocketing. In Houston, as of 3/13/08 we pay $3.10 for unleaded and diesel is $3.89. As you can see the main advantage (I know there are others) of diesel's fuel economy is shot down by the high prices. There are many reasons why diesel is high and will remain high. It stems from excess demand in Europe, AsiaPac and now even the U.S.
 
It is also now more expensive to refine since it is cleaner. Even Katrina has an effect on diesel since many plants were shutdown when they came back on line they focused on producing standard petroleum. Couple low stocks with high demand for diesel and you have the ludicrous prices we see! I wish it wasn't that way because I would go for a diesel CX-9 in a heartbeat!

Well, if you drive 60 or 65 on the highway (tops) you might get it in the CX-9. The one fault in almost everybody's assumption about highway mileage is that you can get 22 (or 21 AWD) if you drive at 75 MPH. This 10-15 MPH difference easily accounts for a 15-20 percent drop in highway mileage vs. the EPA.
 
15 percent drop from 22 MPG = 18.7 MPG
20 percent drop from 22 MPG = 17.6 MPG
 
Driving habits probably account for the rest.
 
So let's say somebody reports getting 15 MPG mixed mileage for a trip that is 60 highway/40 city. This is on par for city mileage, but it probably means that a heavy foot in town and an average highway speed of 75-80 MPH could easily account for the rest.
 
Wet roads make a big difference since the wide tires have so much contact area, and driving in windy conditions or hilly terrain are obviously factors too.

curious about this part
"Wet roads make a big difference since the wide tires have so much contact area, "
 
I live in a rainy neck of the woods and am wondering if I should go for 18"s if I buy a CX-9.
 
TIA

On CX-9, 18" and 20" tires have the same width at 245mm = 24.5cm.
20" wheel/tire combo is heavier than the 18" wheel/tire combo. That will cost you a bit of MPG (but way less than 1mpg)
 
EPA testing of mighway mileage varies speeds around 48mph (2007 and before). If one holds constant speed (say using cruise control), one can definite beat EPA highway mileage even at 65mph. I don't know about the new 2008 rating system since it has been updated.
