EPA ratings of 17/24, but I've averaged barely 18 overall in my first 1200 miles...hoping for a slight improvement after break-in. UPDATE- as of 02/11/2013, I am averaging 20-21mpg overall with 4200 miles on the clock. On a recent 380-mile interstate trip, I managed 22.8mpg with the cruise set at 80mph. see full Mazda CX-9 review

The AWD feature does use more gas than a FWD vehicle. Averages about 17-18 city and about 20 highway. see full Mazda CX-9 review

Have a V8, so I should have expected, but mpg is averaging about 16 around town. With the current gas prices, I dread going to the pump. $90 to fill up the huge tank. see full Mercedes-Benz M-Class review
