Infiniti M Real Gas Mileage: Pros

2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic AWD
Fuel economy is abysmal around town. I guess that's the price you pay for going grocery shopping with over 300 HP. However, on the highway it's very possible to exceed the EPA mileage number. see full Infiniti M review
2006 4dr Sedan 335-horsepower 4.5L V8
5-speed shiftable automatic RWD
V8 power--it's a gas guzzler and could've used an extra 1 or 2 speeds more since it revs so high at highway speeds. see full Infiniti M review
2006 4dr Sedan 335-horsepower 4.5L V8
5-speed shiftable automatic RWD
78,000 miles primarily city driving and rarely use AC-16.9 mpg. 4.5 L V8 great power train with RWD-great fun to drive. see full Infiniti M review

2011 4dr Sedan 330-horsepower 3.7L V6

I get average about 22 MPG with 80% of highway driving, this is with baby footing of the car, in town and climbing the hill, the milage can drop to 18-19. see full Infiniti M review

Large cars get poor milage. 18-20 mpg would like an option to trade some performance for added MPG. see full Infiniti M review
2006 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic RWD
Often avergaed as low as 16mpg on a tank-full of gas. see full Infiniti M review

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

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
