I drove about 15 miles yesterday on electric from a cold start with the EV button pushed, so the ICE was never on. I got onto the highway and drove another 5 miles at 75 MPH, still on all electric. When the battery got to 12%, I pushed the hybrid button. At that point the tach jumped to 1800 RPM, a moment passed and the temperature gauge was at 40%, and I never really felt it happening. I want to think they are merging the ICE RPMs with the electric motor's RPMs where appropriate and keeping it disengaged while it does some warmup process, but I don't know for sure. I would love to read more about it if anyone has more details!Unless you’re teleporting your vehicle to the interstate, everything should be plenty warm by the time you get up to highway speed.
This is my understanding. That there is a merging that happens to allow a quick warmup. I don’t think it takes much. I’ve also read PHEV lube is very lightweight and moves like water at any temp.I want to think they are merging the ICE RPMs with the electric motor's RPMs where appropriate and keeping it disengaged while it does some warmup process, but I don't know for sure.
This is a great question, to be answered by people way smarter than me.Say you're driving on the highway and you run out of electricity. Will the engine get damaged since all the oil is at the bottom of the oil pan but the rpms are quite high? how does the engine lubricate itself fast enough?
Def the wrong kind of engineer to know this soI’m sure a brilliant engineer will be along shortly to break this all down for us. 🙂
Nice article… it’s just missing the fine print “because we can we did, don’t expect your local Jeep mechanics to have even read this article”… kidding it really is the best of both worlds… as long as I’m not the test subject for the water fordinggreat overview! Thanks! I also found this article, which explains how the forward clutch controls interactions between the ICE and the electric motor, and how the rear clutch controls interactions between the electric motor and the transmission. Working both clutches independently lets the system do all of those things you mentioned nearly seamlessly. I recall how much time it took for automakers to get automated manuals like BMW’s SMG working well with only one clutch, so we can hope this system will only get better as the software evolves.

Not sure. I think the electronics dump heat into the PTC and passes to the hearer core and eventually the radiator and engine.How does it transfer heat, is it running fluid through heat syncs or something below the batteries? The inside of my car now looks like a gaming computer? I feel like it needs neon blue ground affects now.
I was watching the engine, coolant, oil pressure, and oil temps from the offroad pages while driving around the other day when the ambient temp was in the mid 80's. All the gauges showed ambient temp with zero oil pressure when the engine was running. However, when I eventually forced an engine start by moderate acceleration the temps climbed quickly, but normally.The 4xe appears to have the ability to transfer waste heat from the electrified drivetrain into the ICE coolant system. Have you ever noticed the engine temp increasing while driving in EV mode even though the ICE hasn't been run?
My suspicion is just waste heat might be transferred. Probably not running the PTC heater as that is a pretty big energy draw.I was watching the engine, coolant, oil pressure, and oil temps from the offroad pages while driving around the other day when the ambient temp was in the mid 80's.

I was expecting like you mentioned, @SnB4xe , that things would electronically heat up but wasnt seeing it. I wonder if that occurs when it is colder outside? Any thoughts on that?
