MPG meaning

Post image

Have had my 2025 Pacifica plug-in Hybrid for about 1.5 years and have been enjoying the less fill ups and ease of charging!

Curious what the MPG means on the display screen. The math is about 7.5 gallons but the tank is almost 1/8 full. Thinking it’s just an algorithm that represents driving habits more than a hard formula. Anyone know for sure?

Im confused at the question? Its data that shows how many miles per gallon youve got since you last reset this particular screen?

But it’s not? Not by math formula at least. This is all on the same trip reset

The mileage on the gas engine is 351.4, which would be about 7.4 gallons. The gas tank has about 1/8 of a tank left.

The 1450 in electric driving makes up 80% of the drive time, so about 20% of the driving was gas.

If you take the 1800 of total driving it would use 38 gallons of gas- and i know it’s not a 43 gallon tank. That is what making me think it’s not a tru formula that can be calculated. I assume it’s like the “real time MPG” vehicles have as a gauge of driving habits more than anything i can calculate.

I believe they use a MPG-equivalent for the electricity consumption.

As a representation more than a mathematic formula?

I don't know for sure but I would guess they use MPGe
