What's Your Average Fuel Economy (HYBRID ONLY)?

I think average fuel economy is limited to 99 based on the artificial ceiling set by Chrysler. Also not sure if it can be reset or resets with the trip odometer.
And yes I need to clean my instrument panel.

Summer - city/short trip driving - ~60-65MPGe.
Winter - city/short trip driving - ~35-40MPGe.
Highway - ~30MPG

My calculations are at the pump, not what the cluster says.
How do you do that though if you are also plugging the vehicle in?
I use an app like Drivvo to keep tabs on mileage and fuel usage, like you would for a normal car.

I don't keep tabs on electricity usage, I can only estimate that since my evse doesn't record kwh.
Thanks, but that doesn't really answer the question. So your numbers posted earlier are based on ignoring the electric contribution to the economy? Kind of a worthless exercise, no?
1200mpg on electric means you didn't buy 40 gallons of gas at $5per gallon.
40g x $5= $200.
(I inflated gas and deflated mpg to 30 so we have numbers skewed in electrics favor)

How many months does the 1200 miles represent?

If it's 2 months, you saved $100 per month.(it can't be 2 months. 30 mile limit x 30 days is 900...but we're skewing toward electric. We know it's 4 months based on reality, 3 months if regen is maxed+)
I haven't the foggiest notion of the electric cost(let's not contaminate the convo with talk of 'free at work').

Someone post their cost per mile for their home electric, then we can carry on.

So far, no home electric factored, it looks like the break even, at a fantastic 1200mpg for 5 years straight, is 5 years. THEN for the NEXT 5 years you save $50 per month.

break even is not a profit. The NEXT time-factor is a 50% return on investment.

(My math is often off by a factor of 10 to encourage others to punch in their own, real, numbers)
I'm not sure why you hang around in the hybrid forum, but let's use some real-world numbers.

We drive our Pacifica ~20,000 miles/year. This is heavily weighted towards short trips. We have had a series of other vehicles similar in size/weight/power to a gas Pacifica, and 20mpg average is being generous. 20,000 miles at 20mpg is 1000 gallons of gas. At $4/gallon, that's $4,000/year for fuel.

With the hybrid we get 30mpg on gas. I figure we do about 6,000 miles/year on hybrid/gas. That's 200 gallons or $800/year for fuel.

On electric we use ~400wH/mile. Our electric rate, all in, is .15/kwH. We do about 14,000 miles/year on electric. That's 5,600kwH/year at a cost of $840.

Total fuel costs for 20,000 miles/year with the hybrid is $1,640/year, versus $4,000 for a gas model. We save $2,360/year.

Further, when we purchased our Hybrid, the out the door price was within $2,000 of the gas model, but we received $7,500 in federal tax rebates. After 5 years of ownership I estimate our total savings will be over $15,000, even accounting for variable gas prices. Not to mention the hybrid version is simply better to drive.

Edit - and for something more on topic for this thread. As I said earlier in the thread, our average economy from the on-board computer is ~60MPGe on electric, ~30MPG on gas. With our 70/30 split of electric to gas usage that equates to a weighted average of 51MPG combined. 20,000 miles/year at 51MPG combined is 392 gallons of gasoline (or equivalent). At $4/gallon that's an annual fuel cost of $1,568...within 5% of the number I calculated above.

When asked why I seek real truths, not esoterics from electric folks;
This scenario is why.
A tainted view based on slightness and that post purchase view wanting to manifest as superiority.

It's not a bad thing.
Not even close to a bad thing.
It is sure nothing to base a purchase on.

People who haven't yet purchased read these posts.
They need to know real, not realities perceived in a way to justify prior purchase.

Miles vs cost seems to be beyond ability because, we're now deep into this thread, and it can't be found as a standard.
Butt feel is asked to be accepted as real.
Gages are asked to be ignored.
Hills are asked to be excused.
Rebates, that used buyers won't get are asked as an offset.
Eventual battery replacement? Like breathing on Mars,...
Do you have any facts to contribute to this conversation or are you content just trolling?

Cvt is fine.
I've had them.
I've had a powerglide and it was nice too.
No problem. Cvt is nice, I'd have one without qualms.
Cvt is not a contributor to cost vs miles not being produced in this thread as a standard.

Mileage is the question, not ride.

The individual misrepresentations, and even the misrepresenters recognizing ANY standard are why I ask;
How much per mile does it cost to drive your electric?

The screen shot of the dash is just too much proof?
I've given you an extensive analysis based on our own, real-world numbers. To which you had no actual reply.

The calculations are quite simple and people can perform them for themselves based on their own situation. However I've also demonstrated that simply using the computer-calculated MPG number gets you pretty darn close and makes the comparison extremely easy.

I know from the dash that we get about 60MPGe on electric. At $4/gallon gas that is .067/mile energy cost. If I instead figure it out from the electric usage, 12kwH of electric into the battery gets us 30 miles. That's 400wH/mile as I stated earlier. At .15/kWH that is also .06/mile energy cost.

If we were driving a gas Pacifica in the same way, it'd average about 20 MPG. That's .20/mile fuel cost.

Do the calculation the easy or the hard way. They both come out about the same.

It should know the difference, otherwise the EV mode consumption readings are useless.
I am failing to see how this is true. The fact that hybrid/electric vehicles can recover some of the energy that would otherwise be discarded as waste heat is one of the prime reasons for their efficiency. Energy recovered from the descent after climbing a hill should absolutely be counted in any MPGe calculation.
You're right, that the best way to calculate MPG is straight fuel/over distance. Since Chrysler combines gas MPG with the electric MPG, it is relatively easy to separate the gas MPG by using the trip odometer and documenting mileage and fuel consumption per fill up.

I did 83 highway miles and based purely on the gas gauge it showed I used exactly 1/8th of a tank, resulting in an average of 40MPG for gas only. The problem with trying to calculate an MPG for electric only is that while the EVSE can provide a rough amount of kWh we don't how much of that is set aside for reserve.
This is not even a remotely accurate way of calculating MPG. As stated multiple times in this thread, the only way to calculate gas MPG is to start and end your calculation with a dead HV battery and no charging. Then divide total miles driven by total amount of fuel used. The 'gas' miles on the trip odometer are not in any way meaningful for anything except for tracking total miles on the gas engine for oil changes, service intervals, etc.

It's very easy to know how much electric the vehicle uses. The 'reserve' is built into the battery and not used. Miles driven divided by energy used gives a very accurate electric efficiency metric. In the case of the Pacifica Hybrid, that's typically ~30 miles for 12.8 kWh of electric, or 2.34 miles/kWh.
