Infiniti EX Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2013	4dr SUV 325-horsepower 3.7L V6 7-speed shiftable automatic AWD	Could be better by today's standards see full Infiniti EX review
2010	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	love the V6 power but the EPA MPG is worrisome see full Infiniti EX review
2010	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic RWD	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
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	Uses premium fuel. 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
2008	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	Slightly low if driving mostly city. see full Infiniti EX review

Nissan Quest Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2014	4dr Minivan, ext. 260-horsepower 3.5L V6 CVT FWD	I was hoping for slightly better fuel economy, but for a 4500 lbs vehicle, I really shouldn't be complaining. In predominantly hilly suburban driving, I'm averaging a couple miles below the estimated city fuel economy number. On 100% hilly highway miles, I'm right about at or maybe 1 mpg above the estimated fuel economy. It would be nice to acheive better highway mpg, but I suppose that's the trade-off for having a torquey engine. You would think the CVT would improve things, and maybe in fact it is helping the poor fuel economy of the aging VQ engine design, but I also think the CVT transmission is a cost-cutting measure by Nissan. It would be nicer to have one of the 7 speed transmissions found in the Infiniti lineup. see full Nissan Quest review
2007	4dr Minivan, ext. 235-horsepower 3.5L V6 5-speed automatic FWD	It is great for going on long trips see full Nissan Quest review
2006	4dr Minivan, ext. 240-horsepower 3.5L V6 5-speed automatic FWD	Rated best in class 3.5L Engine see full Nissan Quest review

2008	4dr Minivan, ext. 235-horsepower 3.5L V6 5-speed automatic FWD	All vans have pitiful fuel economy. The Quest is about average for the class. see full Nissan Quest review
2008	4dr Minivan, ext. 235-horsepower 3.5L V6 5-speed automatic FWD	Averaging ~20mpg. I wish any minivan could get 25+mpg fuel economy. see full Nissan Quest review
