What Our Members Are Saying about the Real Gas Mileage of the 2009 Infiniti G

2009 Infiniti G Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD	To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD	Fuel economy is poor - about 19 MPG average. see full Infiniti G review
2009	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD	With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review
2009	2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	average 18 in town 24 highway. see full Infiniti G review
2009	2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic RWD	You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. 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
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
