So, how long until the market sees these on lots?

5+ years if it ever comes to fruition. Toyota, along with many other companies, recently announced some headway in solid state batteries that would allow for much faster charging and better battery range, but there's a big difference between a small scale prototype showing promise in the lab and a scalable, production ready design. I wouldn't hold my breath on this showing up mass market anytime soon.

So, I recently upgraded from my 2018 Jeep JLU Sport S to a 2023 High Altitude Sahara 4xe. I didn't realize I needed to be a slueth to figure out the range specs. The 4xe is advertised as having 49 MPGe - or 49 Miles Per Gallon estimated. MPGe rating equates to 49 miles on 37.8 kWH of stored energy which is equivalent to 1 gallon of fuel. All the advertisements cite this as a metric for comparing it to other EV Hybrids. However, the Jeep 4xe only has a battery storage capacity of 17 kWH, which is less than 50% of the storage capacity needed to achieve the 49 MPGe. The actual electric range is 21 miles. I purchased the vehicle to save on fuel because my travel distance to work and back is approximately 11 miles round trip. I can easily achieve this, but any side trips do eat into the electric distance I have available for use.

I feel slightly misled by the advertisements. I enjoy the new vehicle and all its features; I am just disappointed that the truth about the actual range was hidden. I was expecting the ability to achieve 49 MPGe, but I did not expect it would be less than half. I paid less than sticker with taxes, title, tags and extended warranty, only having a range of 21 miles in all-electric mode does not in my mind justify the added expense to own this vehicle as a Hybrid. I would not have purchased the Hybrid had I known and understood the MPGe rating and what the vehicle could achieve.

The positive side is that the gas engine achieves approximately 25 mpg. I will post actual calculated MPG once I make my first fill-up.

So I just got my 4xe Willy’s
I’m very confused on the mileage. When I’m fully charged and fully gassed up I would think it should say 375 then obviously it will adjust down. I’m only showing total of 220 and then it goes down from there. They tell me it gets better the more I drive it. That does not make sense to me. How am I supposed to get up to 375 or even close???? Anyone have this issue????

Remember, you fill the tank with gas and the battery with energy, not miles. The predicted range on the 4xe, unlike what some brands do (looking at you Tesla) looks at your previous driving habits to make an estimate of what the range should be. When you first get the vehicle, it has spent much of it's life (and as such, the data points that the computer uses to predict range) doing short drives, longer idle times, and generally very inefficient uses. As such, the prediction is looking back at how efficient it has historically been and seeing nothing but data points of very poor economy. When it projects that forward, it shows very poor range.

The more you drive, the more data it has of actual efficiency in real world conditions to make estimates off of, making the listed range more accurate.

I wouldn't pay the slightest attention to the range value listed until you have at least a couple thousand miles on it.

You'll average somewhere around 19-24mpg (hybrid gas mode) depending on how you drive. You can inflate that number, like many do here, by using it for a lot of short electric only drives.

1. MPGe is mpg-equivalent, not estimated. So... 49 miles on 37.8 kW-hr of electricity is considered 49 mpg-e. Another way of saying this is that 37.8 kW-hr is considered equivalent to a gallon of gasoline. Electricity prices around the nation are generally in the 10-15cents/kW-hr range, making the price of 37.8 hW-hr of electricity range between $3.78 and $5.67, which is a bit high in my neighborhood, but in the realm of the price of a gallon of gasoline.

2. As others have said, the electric range is a completely separate stat from the mpg-e. Just like your gasoline car may get 25 mpg and have a 400 mile range, this vehicle (on electric only mode) gets 49 mpg-e and has a 22 mile (nominal) range. Those numbers are independent, like the length and width of your car are independent. No one (except your lack of knowledge) is hiding anything from you.

MPGe is a unit conceived of by the epa and required to be used on window stickers to describe the efficiency for electric use. All phevs and EVs have to show it in the US.

Yes, they don't dictate how it gets used in advertising materials, but they're responsible for the horrible unit in the first place.

MPG-equivalent is not a horrible unit. It is roughly the electric fuel economy put into a mpg-type number that people are used to seeing. They could put both the electric and gasoline fuel economy numbers in a $/100 miles number, and 99.9% of the people would have no idea how that compares to 25 mpg so... they're trying to spoon feed the public something that everyone can understand, but alas, they overestimated the common man.

 

[slowdave1]

Mpge maybe, but definitely not mpg.

I mean technically, it'd be infinite mpg, because you would go some number of miles with 0 gallons of gasoline, so n/0 = infinity mpg.

Real world depends on shady marketing! 1st off ther are NO consumer energy soirces that can deliver 100% thermal / mechanical / Kwhr eficiency! The wrangler only delivers a 30% gas to electric efficiency and your local electric company sells you kwhrs at $0.15/kwh averaged for all home electric consumers and charging station average $0.21/kwhr. This is the equivilent of $3/gal. The only exception is if you charge using your own solar at kwh. that is the only case where you will get > 30MPGe in the real world. and that group is < 12% of 4xe owners!!!! do the math & Keep it real. MPGE is a marketing slogan and like Logan's Run almost no one achives it!

Mpge is a measurement of electrical efficiency. It is of no relevance if the power used comes from solar, coal, nuclear, etc. The source doesn't matter, the cost of electricity doesn't matter, etc., when it comes to evaluating the mpge of the jeep.

It is simply a conversion of mpkWh where 1 mpkWh = 33.7 mpge. Mpge is a US mandated metric because focus groups performed by the gov determined that using mpkWh was too confusing for the average consumer.

By the way, I did set my friend up with a <$2K 3x500W solar on the roof of his jeep that is costing him <$0.10/Kwhr, and he is averaging 38MPGE on a very flat 12-mile daily commute here in SoCal.

It helps a lot that he has sunny parking spots at both work and home, where he is averaging 6 hours of full sun.

But I don't think you can still get those cheap $400 solar panels anymore.

I am retired and plan on buying a used 4xe with the same setup, as I will drive it <20 miles 4 times a week. And hey, the torque is awesome both on the road and on the Trail!

Is the wind drag from the panels causing that much extra drag to give him a 20%+ reduction in efficiency?

I'm a bit confused. How did you fit 3 - 6 foot x 3 foot panels on the roof of a Jeep. I'm also curious about the design of the electric system which allows charging of the 4XE.
