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

Fuel economy leaves much to be desired, but with proper management of acceleration, can be somewhat decent. see full Infiniti G review

I do a lot of short trips - MPG are around 16-17. Could be better but I knew this going in. see full Infiniti G review

avg 19.5 mpg. Yeah I could do better if I never got on the gas, but then what would be the point of owning a G? see full Infiniti G review

All wheel drive saps about 10% of fuel economy see full Infiniti G review

5-speed shiftable automatic RWD
The fuel economy and the premium fuel requirement are somewhat disappointing. I averaged generally about 16mpg per tank when I lived and worked in a large city. Now that I live and commute to school out in the sticks, I am seeing around 22mpg with the cruise control locked at 55-60 during my 32 mile commute. see full Infiniti G review

An average of 20 mpg (mixed city driving) could be much better, especially with high gas prices see full Infiniti G review
