    Perhaps this has been covered already, but what's the difference between the MPG displayed on the dash vs. the one displayed when I open the app on my phone? My dash says something like 97 MPG, but in the phone app it says it is more like 200 MPG. I'm assuming they are calculated differently, but I don't know how.

    Phone app is a daily mpg whereas the default of the dash display is the mpg for the last ignition on to off.

    Hmmm, I can see that the "Fuel Consumption" number in the "Last Drive" section of the app is the MPG from the "last drive." How is the "Fuel Consumption" number in the "Summary" section calculated?

    So, what is the MPG listed on the dash? Is that the cumulative data for the entire driving life of the car?

    When you cycle through the TRIP button, you'll see a lot of different MPGs listed. Some are for this trip, some are for the entire driving life of the car, some are over the mileage on the trip odometers. Chances are, you aren't comparing apples to apples. I believe the app shows daily MPG.

    Available on the Advanced trim only, as that is the only trim that has the Safety Connect cell phone that provides the info from the car to the Entune servers.
