My CX-9 is 2WD and I've had it for 8 months and put almost 8000 miles on it. I'd estimate that my driving is about 60% highway and 40% city driving most of the time with very few hills. For the first few thousand miles I averaged around 18 to 19mpg. It seems to be a little higher now when I check it, usually between 19 and 20mpg. The worst mileage I ever got was 16 (lots of stop and go when it only had about 2000 on the odo), and the best was 23 (mostly interstate)...

You did good! I purchased a CX9 Sport also. I assume you are ordering one with all the goodies installed or are you going to have those items installed?

Is it just my CX-9? by sigepruss

So I leased a 2008 CX-9 Grand Touring AWD about a month ago. I now have a little over 1000 miles on the car and have gone through 6 tanks of gas! Given most of my miles are city driving, lots of stop and go, but my average MPG is 12 and my best ever, a tank with mostly highway miles was 14. The car drives great, I totally love it, but having the fuel light go on every 200 miles is annoying as heck. Do I bring it in to the dealer?

Heavy stop and go traffic with a 5000lb. vehicle does equal about 12 MPG. Mostly highway should be better than 14 though. I would book an appointment.

First let me say that I love my new 2008 AWD GT CX-9. It is an awesome car to drive! Great appointments for the money. My budget was less than $40k so when I brought the car home for the first time I had to emphasize to my wife that the car was cheaper than it really looks. This being said.....
 
The gas mileage is extremely disappointing. I have filled up three times so far and have been getting a little less than 11mpg in city driving and about 14 highway! Although I knew that my actual mpg would differ from the estimated 15/21 mpg I did not expect this huge gap especially with the highway. Gas milage was one reason (albeit not the main reason) why I stayed away from looking at SUV's with V-8 but I might as well be driving a V-8 with this poor milage. I hope that the poor mileage is a result of some defect that will hopefully be fixed with a recall.

Maybe it has to do with the larger size engine you have in your 2008. I sure don't miss the extra power, and as you can see, I get a fairly decent gas milage (if I don't drive like the Germans). The worst milage I got was 14MPG, the best was 24MPG. Since it's Winter time already over here & I'm not crazy, I will wait for better road conditions before I do the real world Maximum Speed Test. The fastest I had the Mazda was 115MPH the beginning of September. With speed like this, forget about 6th Gear....

I've had my 2007 CX-9 w/FWD with the 3.5 since last February and am about to hit the 10k mark. So far the worst mileage I've had (in stop and go city) has been 15mpg, and the best I've got on freeway driving is 23mpg. The last few tanks, with combined city/highway, have been between 19 and 20...

Initial Mileage - 2008 CX-9 by pulleydog

I picked up my car today from the dealer and drove home - 100 miles. The tank was filled by the dealership before I took delivery. I did approximately 85% highway driving against 20~40 MPH winds. I couldn't quite squeeze 5 gallons into it when I filled up at home. 20 mpg on a new car, fighting a head wind, isn't too shabby. Granted, it's only 1 instance, but I was starting to get nervous about the mileage I might expect in the 2008 after reading these other posts. I just wanted to let others know that those getting poor fuel economy might be the exception, rather than the rule. I was very relieved when the pump shut off at 4.7 gals. I drive about 700 miles per week (on average) so I will check back with more updates in a week or two.
