What Our Members Are Saying about the Real Gas Mileage of the 2008 Infiniti EX

2008 Infiniti EX Real Gas Mileage: Cons
YearBody/PowertrainComment
2009 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 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
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic RWD		 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
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 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
