2021 vs. 2024 MPG

[BXFXJeep]

Right, I understand. I just thought the 4xe claim to fame was some improved mpg like most hybrids. Is it only the short miles on battery power?

The 4xe is a PHEV, PHEVs are generally just a regular gas vehicle outfitted with an electric system to handle shorter low speed trips using electricity, PHEVs generally lack any efficiency tweaks, PHEVs are known to have a bit lower mpg on the highway. My highway is about 20+ mpg at around 65-70-80mph, I mostly sit at 70, and gun it for stretches at times. With the 3.6 I got about 22+ mpg, same type of driving.

The benefits of the the PHEV is the poor mpg of the in the city, is offset with the electric motor. The PHEV is not intended to be a regular highway runner, and the electric miles will significantly offset the odd highway miles.... however critics tend to look at highway mpg in isolation, completely discounting the city electric miles, you can decide why they choose to do that. The PHEV is usually a low mileage vehicle.

My driving has been consistent for 30 years getting 14-15mpg city driving with 6cyl Wranglers, the bulk of my driving is gas guzzling city stop and go.

My case is somewhat extreme because I live where is 8-10 cents per kWh, means 20 miles cost 13kWh x 8 cents= $1.30 and is $6 a gallon, means 20 miles cost $7+...all Canadian dollars.

Some like to claim the electric 20 miles can be covered with 1 gallon of gas, no it doesn't work that way, some people get 25+ electric miles, I get around 20+ electric miles. The 20 miles electric range is usually trips that would be 15mpg. So the 20 miles take more than 1 gallon.

In the past I went to the gas station every week, which was about $70 x 52 at the low end.

Now I go to the gas station about 5x a year, using gas mostly for heat on really cold days in the winter..

This is great info. How much did your electric bill increase?

So, I had one of the earlier 2021 4xe's. It was a fully optioned Sahara. I traded in for a 2024 High Altitude, which is basically a fully optioned Sahara with all-terrain tires. Both had the same axle ratio with the LSD and the same size wheels and tires ('24 Sahara's have more narrow tires for some reason)

With the '21 Sahara, I would consistently get 21-22 mpg cruising just under 75 on the highway. I could have it loaded up with 4 people and cargo with 4 bikes hanging off the back and even have eSave/regen mode on.

With the '24 High Altitude, I can barely sniff 20 cruising at 65. Just completed a 750 mile road trip on I-90 from Boston to Rochester NY and back. One passenger with a little bit of luggage, cruising just under 75 the whole way. I got 16mpg overall!

While I expected a hit from the General AT's vs the Continental All-seasons, can that big of a difference possibly be explained by tires alone?

It's sad, but the marketing is done by FCA for the 4XE is very misleading. Unfortunately far too many people find out after they've made a $50,000+ purchase.

If you're not driving under 20 mi between charges, there's really no point in purchasing a 4XE.

If you want the best mileage available on a Wrangler, and you do a fair amount of highway driving, the EcoDiesel is going to be your best option!

I ended up resetting my trip timer after driving driving through about 2/5 of a tank...

The big thing to keep in mind here is that my Jeep still thinks that it is driving on 32-in tires, when in fact I'm running 37s. So in actuality my MPGs are much better than what it shows on the dash, for I am covering a greater distance than the Jeep thinks I am. But still, 22 mpgs with 37s is unheard of with any other powertrain on the Jeep Wrangler JLU.

This is great info. How much did your electric bill increase?

I don't have charging at home, I use nearby public chargers a mixture of free to paid. If I use free for longer charge, and paid for top ups. All the chargers are a short walking distance, probably easier parking at the charger, than driving 2 levels down in the underground garage.

If I only use paid,

$1.30 = 20 miles at 8-10 cents a kWh vs $7+ at $6 a gallon, for me the city milage cost at least 5x less than gas.

If your per mile cost more than gas there's no savings.

City driving in full electric to me is a lot better than gas, performance wise.

Highway at a slightly lower mpg is also better with more power.

Fuel cost savings is just one benefit, some people are buying for additional power etc.

The 4xe or PHEV is not a direct replacement for a gas or even a BEV, individuals need to figure this out for themselves.

If the major benefit it's cost, the math is extremely simple, mpg should never be a factor with a PHEV, if mpg is a factor, it is simple you are making a mistake, cost per mile is more relevant.

There really isn't anything like mpg with a PHEV.

Last year I did, and if I paid for all my

7,761 miles @ 10c a kWh, 13kWh = 20 miles
1,359 miles at $6 a gallon at 20mpg

I've done 6 150 mile tests and o e c9mmon denominator I have found is the calculated mpg is inaccurate without a rhyme or reason. Today the faucet said 19.6 and after filling up I actually was at 22.1 mpg. Yesterday it said 21.2 mpg and actual was 20.14 mpg. The hybrid is good for short trips and then recharging but not much of an advantage since a full charge at a charge point station from, 15% to 98% cost me 2.68. Fill up of gas was 2.79 gallon so I guess I saved 11 cents. If gas was higher it would be better savings. I do think the overall getup and go I where it's worth it. The ice only is just enemic and sad
