Infiniti QX50 Mileage / MPG

Fuelly.com shows the average for the EX35 to be 20mpg

not that great. any EX owners have any data?

Compared to the competition 20mpg is a bit low. I wonder if the QX50 is any different. Probably not.. We are talking real world mileage here.

I wouldn't doubt if the mpg improved slightly for the next model just due to slight improvements in software. Will Infiniti be changing to the 9 speed auto transmission soon? Cause that improves mpg by a bit too.

Not only will ECU tuning help but changing some of the fuel and air components to something better, even internal engine parts. Sometimes from year to year car makers do a lot of changes under the hood that we don't notice until we really dig deep

Fuel economy has become a much bigger factor when buying a car than it used to be. So I think car companies are putting more emphasis on this when they create products. You've got to keep up with the competition at least.

maybe not on the refresh but very soon Infiniti, as well as all the other car companies, will switch to transmissions with more gears, and that will bring fuel economy ratings up across the board.

The fuel economy challenge is getting so bad that car makers will lie about the MPG numbers they get just to say they get more MPG's than all of the competition. It's on reason why I like to wait for real world numbers, nothing better than that.

Considering that any fuel efficiency test will be different from others based on how they set up the test, it makes sense that car manufacturers tend to choose the best data that makes their cars look most efficient. It's like in science class when you would do the experiment twice and choose the easier set of data to work with for your lab report. (At least that is what I did )

Fuelly is pretty unreliable for the QX50. There are no QX50s listed but thats to be expected still, for 2008 there are 4 EX35s listed and they're averaging 17.7 mpg over 24,000 miles. 2010 saw 1 car average 25 mpg over 1,238 miles and 2011 had the EX doing 17.9 average from 1 car over 3,176.

Not the widest sample but it should give you a hint or 2.

I think changing the transmission is the easiest way for Infiniti to get better mileage out of the car. At least in terms of cost.

a DCT is the way to go, up performance and MPG's.
other brands are holding back on DCT, might be time for Infiniti to do it and stand out from the rest.

I'm not entirely sure if a DCT is requried for a car like the qX50.

Just a 7 or 8 speed automatic would already improve acceleration and mileage

DCTs are expensive.
