2009 Infiniti G Real Gas Mileage: Pros

A downside if you are used to more fuel efficient cars--you pay for performance. NOte that I had a 2005 Chrysler PT Cruiser turbo convertilble (4 cyl.) before I bought the G. It got worse gas mileage.

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.

Fuel economy is poor - about 19 MPG average.

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.

average 18 in town 24 highway.

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.

As noted before, the G will get about 18 around town in stop and go, about 27-28 on the highway.
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD
Not too great. My average is 19 - 20 mpg, mostly city.

burns too much fuel, I would like another 6 mpg even if power were cut

With all that power available its hard not to use it. Expect in city driving to deliver less than 20mpg.

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.
