What Our Members Are Saying about the Real Gas Mileage of the Infiniti M

Infiniti M Real Gas Mileage: Pros
YearBody/PowertrainComment
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.
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.
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.

2012 4dr Sedan 330-horsepower 3.7L V6

I get around 17 city/25 highway. Not impressive but this is not why you buy a car like this.
2011 4dr Sedan 420-horsepower 5.6L V8
7-speed shiftable automatic AWD
Fairly poor.
2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic RWD
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.
2008 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic AWD
Gas mileage stinks.
2008 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic RWD
average 21 hwy
2008 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic RWD
needs a 6th gear, since there is too much revving in 5th gear while cruising. they put a 6th gear in the 2009 version
2007 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic AWD
Large cars get poor milage. 18-20 mpg would like an option to trade some performance for added MPG.
2007 4dr Sedan 325-horsepower 4.5L V8
5-speed shiftable automatic RWD
Averages about 18.5 mpg in mixed suburban/urban/freeway driving. Can get thirsty when you get on the gas, but duh...
2007 4dr Sedan 325-horsepower 4.5L V8
5-speed shiftable automatic RWD
16.9 in city traffice 18.nothing on the highway...blah!
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.
