Thoughts on ETorque long-term?

[four low]

Also, there undoubtedly will be " E Torque Delete" kits available by then, to convert to ESS type, or all electric motor install kits

Does anyone know why FCA removed the eTorque system from the 2.0 and put it on the 3.6?

No one knows. Could be many many, many reasons that we haven’t even considered.

Possibly the 3.6 makes a little less low end torque than the 2.0t

I highly doubt this. At idle (actually with the engine stopped), the turbo hasn't spooled, and the 2.0 will act as though it's naturally aspirated 2.0.

Think about it, it doesn't take 90ft.lbs of torque to turn over a healthy 3.6. I can turn over a 3.6 with a 1/" drive ratchet .

I should have clarified this earlier: Obviously the torque is used for more than just starting the engine, as it wouldn't be able to be considered a hybrid if it were just a second starter motor. The BSG is not just starting the engine... it is also accelerating it to idle speed in a fraction of a second. This is why the ESS in the eTorque is smooth vs. the non eTorque.

Turning over an engine at 2 RPM by hand takes a lot less torque than the starter cranking the motor at ~200 RPM, which also takes a lot less torque than accelerating everything to ~1000 RPM in less than 1 second. Yes, the tune allows for less than a full rotation before starting, but you still have to rotate at least through one compression cycle. The larger rotating mass or one with more friction (cylinders/camshafts/compression/etc.) is going to be harder to get spinning quickly for a smooth start.

Add me to the list of those who wanted to avoid e-torque at all costs and are now very happy with it.

Now I'm even more curious on why Jeep decided to put a 3.6 eTorque engine in the JL, but not offer it in the JT. For the 2021 model year.

Several of us speculated on this a while back. We concluded its to create more space between the “hybrids” with the e-torque system and the actual PHEV 4xe.

E torque does not have a small aux battery. Yours is not an e torque system if you have that.

Really? Not trying to be contrary, but everything I've seen/read suggests otherwise, including this Chrysler article, which states "A 48-volt battery pack works with the motor generator...":

Now I'm confused, but not curious enough (yet) to actually pull my fender off and just check for myself.

You are confusing the terms. The “small aux battery” for non e torque systems are located behind the glovebox. Its like a small motorcycle battery.
The 48v e torque battery is located underneath the jeep in the rear. Its much bigger, liquid cooled, and encased, so calling it a small aux battery would be inappropriate. Hope this helps.

LOL...thanks, and appreciate the clarification! I assume the battery location is the same for 3.6L on a 2-door?

It's probably mostly a balance of CAFE fines, cost of production, and selling price.

^^^ this.

Plus FCA, especially under Marchionne, liked to live on the edge of what is legal and illegal.

Also to clarify.

If you got the non-etorque, be ready for a set of bloody knuckles to replace that $&#$^!@^%&@#^%POS small battery under the fuse box.

Luckily, I ordered etorque but still haven't laid eyes on it yet, as my JL won't arrive until next week (fingers crossed).

No one with etorque has actually looked under the fuse box to see if it’s just empty space or if they used the space to put something else related to eTorque, but as the poster after you said, we can guarantee you will not find a small auxiliary battery there, or the eTorque battery for that matter, because the eTorque Lithium battery is next to the gas tank on the drivers side and it has its own liquid cooling and skid plate.

Here is a schematic of where the battery is located, the battery being number 3, with #1 being the Motor/Generator Unit and #2 being the orange 48v positive and negative cables going between the PPU and the MGU:

Here is a photo of it under the jeep:

Here is the battery (called a Power Pack Unit) out of the Jeep:

The PPU includes a 3kW DC to DC converter used to power all accessories during a Start/Stop event and to charge the conventional Lead Acid battery whenever the engine is running.

And finally, here is a photo of the undercarriage of a Jeep without eTorque, where you can see the empty space beside the gas tank where Jeep engineers chose to place the PPU on eTorque Jeeps:

I hope this helps!
