OK This is NOT a car to buy if MPG is important although I am getting over 23 MPG avg. It is a POWERFUL car with a great drive train ready like a race horse at the gate to giddy up and it does when you need it on premium recommended fuel....in spades. I don't drive enough to care about fuel economy all that much. Not an econobox. see full Infiniti EX review

17MPG in the city is a little disappointing for a vehicle with such finesse and reputation. I would guess Infiniti would cater to the masses with styling, performance and a little more economy. Not asking for miracles but I'm sure they could squeeze out 3 or 4 more MPG with the same 3.5L V6 see full Infiniti EX review

I average about 20 miles per gallon on premium fuel - with a mix of street and highway driving. I typically get 16 mpg in the city and 24 on the highway. Some of this is attributable to the 5 speed transmission on the car, which favors acceleration to economy. I imagine the 7 speed transmission should help the car get better highway economy. see full Infiniti EX review

Expensive to keep fuelled given poor gas mileage and costs of premium fuel. Number 1 reason I am thinking of switching to another car. see full Infiniti EX review
