2005 4dr SUV 153-horsepower 2.3L I4
4-speed automatic AWD		 For an SUV with a 4cyl and 4wd I get avg of 22 MPG mixed city and highway. I usually get 23-26 on freeway only. This is good. see full Mercury Mariner review

2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
