Can I see my MPG on a new trip as I am driving

[harwax]

Hi All,

I have 2015 Genesis tech package 3.8. If I set trip "A" or trip "B" to zero and start driving, can I see my actual MPG as the trip progresses, or do I have to wait until I turn off engine for it to display MPG.

Thanks

You have to toggle to the fuel economy screen. However, you also have to reset that if you want to see the mileage for that particular trip. As far as I can tell, there is no trip-based MPG other than the one that briefly appears when you turn the car off (not always - if you leave a window open, etc... when you turn the car off, you get a warning instead).

That's what I was afraid of. I don't want to reset (lose) my "long term mileage" at the expense of a "short term" trip. Don't understand why they chose MPH over MPG for your every day daily travel.

Agree entirely - Honda does this nicely. I believe you can set the mileage to automatically reset with each fill-up which is not useful in my opinion.

I love the feature that resets automatically when I fill up. There is alway an option to turn that off on the two cars I have had that do it.

The displayed mileage is only an estimate; however, I find that my 2015 displayed mileage is fairly close to the pump measurement while my 2009 displayed mileage (V8) was rather optimistic. The closer 2015 displayed mileage may stem from Hyundai's faux pas in overstating mileage a few years ago and getting into trouble. My wife gets a rebate on her Tucson every so often.

How do I get to the option to automatically reset MPG when filling up & what happens if I only add a few gallons and not fill up, will it automatically reset because it thought I filled up the tank.

Agreed the displayed mileage on this car is very close.

It should just calculate off of what is in the tank. Most tanks nowadays have a sensor and will compute from what is actually in the tank. Our Honda does it so I would be surprised if the new Genesis didn't do it.

If it calculates off the tank, then it doesn't know when I get gas, so then it can't reset everytime I go and fill up (which is what some earlier posts indicated).

MPG does not calculate from what is remaining in the tank. MPG is miles driven divided by fuel used. Miles to empty does use the tank level multiplied by MPG.

Since MPG resets when gas is added to the tank, it appears to me that some fixed number is used to initially calculate miles to empty when filling up rather than using the previous MPG. I have noticed that a full tank seems to yield the same number each time.

Mine varies 1-2 mpg higher than actual. The computer reading always gives me false hope that I'm getting more than 15 mpg.

My actual is almost always 1.4 to 1.6 mpg lower than the display indicates. That being said I'm still pretty happy with 26 to 27 mpg actual consistently on the highway just driving normal and 80-ish on a car with AWD.

I also hate to read the manual.
However, the trip MPG and tank refuel MPG is explained on pages 3-89 through 3-92 of your 2015 Genesis Owner's Manual.

Of course, the accuracy of the readout is somewhat suspect, since the fuel consumption is dependent on the accuracy of the fuel tank measuring instrumentation. If you have selected auto reset, the MPG resets only when more than 1.6 Gallons has been added to the tank. The readout also assumes that the vehicle is on level ground. If you deselect auto reset, you can reset the milage by pressing and holding OK when viewing the MPG.

The best way the check milage is the old fashioned way: fill the tank and record the milage. Divide the driven milage by the number of gallons added to the tank at the second fill up.

I have a 3.8 2015, too, AWD. The car says I'm getting 20 to 21 MPG. I haven't done the manual thing yet. I only have about 2200 miles so far.

The strange thing about the two Trip Odometers is that you are given miles, time and speed. Who cares about average speed. They could just as well have stuck in MPG for the trip instead.
