It is between 25-29.2 on the highway depending on headwinds. It seems sensitive to wind, mileage-wise. In town is excellent. In 4k miles the worst tank has been 23.2 when it was brand new and very cold out. City mileage is understated in my opinion. see full Nissan Maxima review

Depends on a lot on your right foot. Driven like a Prius, 26 MPG city and 33 MPG highway. Driven normally with occasionally throttle bursts, 27 MPG highway, 21 MPG combined. The CVT ratio spread maxes out at 2200 RPM at 75; a little high for MPG. see full Nissan Maxima review

This car loves to suck gas especially when pushed. And not just any gas, the high compression VQ35DE engine requires premium. In my experiences anything less than 91 octane will yield poor performance and odd engine noises. I average 17-18 mpg at best. see full Nissan Maxima review

What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review

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

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

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
