Hybrid mode useless.

[Bmeister]

...The nice thing is, in one of my conversations with Dan Fry in the Ask The Expert series I did on YouTube, he said he and his team were really intrigued with how many people would like to see a blended mode made available in future models. The information they are gathering from the Jeep 4XE Fans group on Facebook is making it back to the design conversations. So a blended hybrid option might just be on the white board of a future design session.

That is great news, Chris, thank you. Every time I hear engineer feedback I am more impressed by the Jeep engineering team. It should be a simple flash/download update I'd think.

The blended mode will be ideal for people like me who know we have a 60-80 mile round trip ahead and don't want the ICE coming on cold while on the highway. It would also be beneficial to the ICE longevity to be able to run blended in the frigid winters when the engine needs to run anyway; I'd just like it to stay on until fully warmed up which it did not always do without my intervention.

The thread began with a question about the hybrid mode vs. other available modes, not "How do I get the most electric miles/best gas mileage?' etc...

By forcing the PHEV to perform in electric mode as much as possible (as has been suggested) (and thereby likening such performance to a pure EV, in my example a Tesla, but pick any EV you want), you are denying the system to use the ICE periodically to circulate/evaporate/consume the fuel contaminates that build up without use. (see FORM). Also denying the ability to extend the vehicles range, to assist uphill or in the cold, with the HVAC system, etc. etc.

In reality, it is what it was designed to be...a PHEV that co-ordinates the use of electric only propulsion, gasoline propulsion, and, for the majority of its use, a combination of the two poewer modes.

I don't see in his words where he made a comparison to a Tesla. He merely stated that the way to make the most of the hybrid system is to plug in as often as you can. @bjm00se said.

You might re-read his complete statement....the part about running as much as possible with the engine off. That is not what a PHEV is designed or intended to do.....

No more untrue statement has ever been posted here.....

Perhaps you should talk to the engineers who designed this Jeep PHEV to run as much as possible with the engine off. That is exactly what it does in Hybrid mode, which is the default mode the vehicle always starts in.

You cannot deny the 4xe from doing it's ICE maintenance, that maintenance is based on the algorithm, and the maintenance will be performed as needed.

However if you do not charge the battery, then you cannot maximize the benefit of the electric motors.

Yeah, it's a weird, dirty MPG number. I have yet to figure out the math. If you manually figure your MPG using only the miles driven when the engine is running, it doesn't equate to the MPG on screen 5. If you calculate all miles driven and fuel used, it still doesn't add up. I've reset both trip odometers and reset screen 5 at a fill up then driven out a tank and just can't figure out how it's coming up with that number on screen 5.

Hey Chris - here's the math if anyone is interested:

What year is your Jeep? We have a 2021 and I thought the same thing as you. We went in for service and they did a bunch of recall stuff. Now, the max regen button remembers the last setting when you turn it off and on again, AND the hybrid mode is COMPLETELY different. I think the calibration on the early models was jacked up and they did a reprogram to fix it.

I thought that @Chris Hall had the first 4xe customer delivered in the US. I got some gloves if you guys wanna settle this real quick…??

Delivered 3/30/21!! But ya never made a YouTube video??

What you are describing would be exactly right in a standard hybrid or HEV. But the idea of a PHEV is to give it electric only range. Like some others have said, you can force a blended hybrid mode by pulling the shifter over. It will spread the battery use across around 70 miles.

Ya glad to know it’s working normally, definitely agree a more hybrid blend is needed for the 3 modes as ev and hybrid aren’t THAT different!

It's actually weirder than that. The 4xe seems to apply some sort of gas equivalent value to miles driven under electric only, like the opposite of how mpge is done, for the mpg number in the dash. But 100% agreed that it's a largely useless number.

Ive hade the PacHy for years (same hybrid setup) and its true. The mpg meter on the dash is ridiculous. However, I have a working hypothesis that does well enough. Its giving you efficiency in mpg AND mpge, taking in to account the gas used and the "energy" that you used. The energy is based on how much energy it THINKS is equivalent to gas and while I recognize that this is the definition of mpge, its NOT the typical 33.7 kwh/ gallon. It seems like its doing something like 20kwh/gallon. That is definitely weird.
