2010 Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
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
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
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
