2007 Infiniti G Real Gas Mileage: Pros
YearBody/PowertrainComment
2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 My average for the life of the car is 21MPG. Not too bad for a car with this power and my lead foot. see full Infiniti G review
2007 Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 burns too much fuel, I would like another 6 mpg even if power were cut see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 With all that power available its hard not to use it. Expect in city driving to deliver less than 20mpg. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 5th gear is short and really infringes on getting decent mileage (15-17 in mixed and 22-23 hwy). Accurate EPA figures but the new 7 speed AT for 2009 really helps. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 The car is just not about fuel economy. You pay for performance. I get ~18 in suburb style driving and ~23 on highway but that maybe just me. see full Infiniti G review
2008 2dr Coupe 330-horsepower 3.7L V6
5-speed shiftable automatic RWD		 With both highway and city driving, I would only average 19 mpg with moderate gas pedal use vs 24 mpg in the c300, which is AWD. One month of strictly city driving with heavy gas pedal use I average only 13mpg... Yikes! see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Not too great. My average is 19 - 20 mpg, mostly city. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Takes a lot of fuel... 14L/100km about. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
6-speed manual RWD		 While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 To high! see full Infiniti G review
2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Fuel economy leaves much to be desired, but with proper management of acceleration, can be somewhat decent. see full Infiniti G review
