Actual mpg after 6000 miles

I’ve crested 6000 miles in a little more than six months of ownership. My computer has figured around 36 mpg, but I calculated miles against how many gallons I actually used. The result is 68 mpg! I’m one of those fortunate folks that the 4xe Jeep is perfect for: lots of shorter trips and occasional long one. Additionally we have relatively cheap electricity. I’m always plugged in at home with a level 2 I added for less than $300. It seems it will save a lot on gas, but I realize it will never cover the premium price for the Summit 4xe. But I get to drive in a much nicer, much better performance car for around the same as a less expensive model. At a minimum the 4xe allows you to better rationalize the splurge😎.

My parents had a Ford Fusion PHEV. They used around town and got gas 3-4 times per year.

I wouldn't say that.

Have you considered the potential tax-break if you're eligible and even if not, compared the current residual value of your 4xe to the regular one? I would bet that the latter is clearly higher than the one of the ICE-version.

I decided to lease my vehicles and the monthly payment is lower than the regular models from day 1 due to the tax incentives being applied right away.

I qualified for almost $5000 in tax refund (all I owed) so that definitely helped. I’m not sure on residual values relative to ICE SUVs. I wonder if electric will go down faster, but I’m not sure. In any event, I meant going for a PHEV (which I wanted because I could make use of it on my short drives) but one that had 4x4 off road capability ( because I do go to the high country in Colorado, Montana and Idaho), of which the GC4xe is it, versus just getting a good 4x4 SUV, which I could have gotten for $50,000. It’s the $20,000 differential (including tax rebate) that I meant I wasn’t sure I’d recover by gas savings. Still, I’m very happy with it even if gas savings don’t really justify the price difference. If I’ve figured wrong and can better match up prices, then I’ll be extra happy with the gas savings. It also really zooms when you want it to.

It will be interesting to see how this plays out...

I owned a diesel pickup for hauling trailers (horse, flatbed, etc), and had a discussion several times on the value of the extra cost of a diesel vs. gas pickup.
My thought was the savings on the amount of fuel used (accounting for the now higher diesel cost) could be marginal, depending on the percentage of time actually used hauling.
But I figured if two identical trucks (with the exception of the engines) with >150k miles were for sale side by side the diesel would hold more value.
Hoping the PHEV's see the same results.

For my, and all, our sake's I hope you are right.

I owned an '03 diesel and that school of thought was common then, but the truck guys I know now lean more towards gassers, unless a high percentage of the time is heavy towing. Apparently all the new emissions control stuff that has been phased in dropped fuel economy and reliability for diesels.
Think I am going to deliberately do a 70 mile round trip to burn some gas off today. First month plus of ownership I have 400 miles and still above 3/4 of tank of dealer gas. Keep Fuel Oil Refresh from happening.

your 68 compared to dash reading of 36, you just have to give up trying to figure it out, it has some formula based on national average of electric and gasoline cost and its extremely random in how it calculates. Enjoy what you got, it took me a solid 6 months to accept you cant make sense out of it, in my 6k of mile I only burned 49 gallons of gas, that does not mean I got 122 MPG, it means I used alot of electricity in my efforts.

Ironically you said your in dash came in at 36, because at my 6k I crunched numbers, placed a value on electricity to equate out to gasoline used, and my 6000 mile reading came in at 36 MPG.

My in dash reads 54.8 as a max, I can go another two weeks on E only and it will read 54.8, another oddity is, a three minute stint of running out of E and onto ICE to get home will result in a instant drop to 48, and will spend next two weeks attempting to build back to 54.8
On my Summit Reserve, the last two fill-ups:

System: 32.8 MPG, Actual: 46.25 MPG
System: 33.1 MPG, Actual: 48.99 MPG

Trailhawk (more miles driven outside its electric range):

System: 27.8 MPG, Actual: 32.78 MPG
System: 27.3 MPG, Actual: 31.99 MPG

Which charger, please? And that's not including the electrician, right?

big controversy on here when you start chatting brands, and remember your vehicle has the charger and controls draw and such, what you need is a EVSE and a 240 outlet in the garage. EVSE is just a glorified power strip really.

Got it, thanks!

Except for all the safety circuitry required that some of the cheap brands neglect to use, resulting in lots of vehicle damage.

Sure because the fault is the charger more than crappy Chinese batteries.

The circuits are built into the Jeep. The charger should not need to do more than provide power.

As for the concept that the PHEV will hold more value than other ICE or Diesel trucks, I doubt it highly. Once they figure out the battery replacement/recycling etc, maybe they will be more valuable. I forecast in the next 3-4 years we shift from EV to Hydrogen. I hate the idea, but there is little Electric infra yet and the power grid will be the next week link. Hydrogen can be maintained mostly with the current Petrol distribution network. Let's see.

There two main issues with the crappy Chinese evses, other than general workmanship issues, are some are missing the ccid circuitry and many have way undersized wires/components for the load they're carrying.

The ones missing ccid circuitry cause lots of damage to evs, regardless of the brand of the vehicle. This isn't a "well jeeps have bad onboard chargers and that's the actual problem" situation.

Undersized wiring and components results in parts overheating, fires etc. Again, nothing the vehicle has to do with this.

play nice those are not crappy Chinese batteries they are somewhat less crappy Korean batteries

Awesome info. Once we get past 1500 miles or so, I plan on running our GC In Electric mode all the time. Right now we are using hybrid mode to use more gas and we still took 3 weeks for the first tank of gas charging on the regular. Compared to $100/week for my old GL450, the Jeep is basically free. :)

You can actually keep your vehicle running in Hybrid. When fully charged, running of the electric system will be highly prioritized in Hybrid mode as well. Also, when you are trying to "always" run in electric mode, the system probably won't let you and force you to run on gas at one point.

Yes, I just meant that we will run in EV mode as much as possible for daily use. I have a level 2 charger, so even mid day recharging is easy now (that level 1 was killing my soul).
