420-450 per tank. Putting in about 15 gallons.
Unless you are going down hill, you will find it difficult to go into EV mode over 63mph.
Whether it's a hybrid or not, a speed of 80 will greatly diminish one's efficiency. From what I've read, as speed increases arithmetically, the efficiency decreases geometrically. (For those who are math-challenged, arithmetically means by addition, and geometrically means by multiplication). The EPA, from what I understand, uses 60-65 mph to figure highway mileage.
Actually, if remember correctly the EPA uses a slower speed than that on the new tests. I posted a link on another forum with the details on how the MPG figures are calculated (and why they are so skewed) on another forum. I'll see if I can find it and post it here.

It's the 70% city driving that is pushing your overall mileage down I would guess. I'm thinking that you must have a lot of lights etc. or other stop and go with few low speed crusing miles where EV mode could kick in and increase MPG's.
Since the onset of colder weather (Washington DC area - Maryland) my mileage has dropped quite a bit. I'm averaging about 25MPG in mostly city driving (85% City / 15% highway). Was getting around 28MPG during the fall. I don't have that far to drive to/from work (6 miles) so I don't think the vehicle gets fully warmed during my daily commute which I think affects the % of time it is in electric mode. Also wish the MPG gauge was more accurate. It consistently reports about 10% better mileage than I am actually getting.
I drive mostly city and little highway to work and back. I usually get an average of 27. I think this is mostly start and stop from traffic lights which uses lots of power.
Agreed. The winter weather has certainly affected my mileage as well. Mine will barely go into EV mode for the first 15 minutes of my drive, until the engine warms up. It was easy to get 32+ mpg (on the gauge) the actual mpg is about 30, but now I'm hard pressed to get 27mpg, which is about 25mpg actual on my Q50S Hybrid......
Most hybrids tend to get better or equal mileage in the city versus highway, so this still doesn't add up (2013 Prius is rated at 51 city / 48 hwy). Not sure why the Infiniti hybrid system is so weak in the city. I have an AWD gasser and I drive about 50/50 split and average about 21mpgs.
Uh, considering that the Prius has a 1.8L engine, and the Q50 has one twice the displacement, and the Q50 is so much heavier than the Prius, it's no surprise that the Prius does better in the city, comparatively. On the highway, once you reach cruising speed, it takes less energy to keep going. I got the hybrid because I wanted much better mileage, but I still wanted a CAR, not an appliance.
I've made a lot of short trips lately, so my local mileage has suffered, having dropped to around 25. My highway trips have yielded the 34-36 mpg range, which is what I expected.That sounds like something is wrong.
I think in our area they increase the amount of ethanol in the gas to reduce emissions in the winter. I read an article on it once, and can't remember the details on the why's and how's, but this will decrease your gas mileage.
