2013 4dr SUV turbocharged 240hp 3.0L V6 Diesel
7-speed shiftable automatic AWD		 Upper 20's on highway and mid-20's in suburbia from a vehicle that weighs 5K lbs. see full Mercedes-Benz M-Class review
2009 4dr SUV turbocharged 210hp 3.0L V6 Diesel
7-speed shiftable automatic AWD		 Other luxury cars/SUVs require premium gas. Diesel could be same or even cheaper than regular gas and with immense torque and a somewhat light foot I get almost 25Mpg see full Mercedes-Benz M-Class review
2007 4dr SUV turbocharged 215hp 3.0L V6 Diesel
7-speed shiftable automatic AWD		 5000 lbs vehicle. Gets 32 mpg on highway up to 75 mph, faster than that mpg drops. 23 to 24 mpg around town see full Mercedes-Benz M-Class review

2007 4dr SUV 302-horsepower 5.0L V8
7-speed shiftable automatic AWD		 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

6-speed automatic FWD		 Has been very good and getting better see full Mercury Mariner review
2009 4dr SUV 240-horsepower 3.0L V6
6-speed automatic FWD		 Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review
2007 4dr SUV 200-horsepower 3.0L V6
4-speed automatic AWD		 For the first almost three years after we got the car, it gave 21+ mpg in town & 24+ mpg on the road. see full Mercury Mariner review
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

YearBody/PowertrainComment
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
