Etorque usage info

[ParisJeep]

Hello,
I've been trying to wrap my head around this etorque system on my 22 rubicon and was hoping for some people to talk things out with.

It sounds like etorque is sometimes called a mild hybrid system and as such can punch the wheels with some high torque off the line similar to the 4xe. Most of the people who have mentioned this say it only works for half a rotation of the wheels or something like this but why not more, especially in an off-road situation like climbing an obstacle or recovering a vehicle? Is there any way to control this like do i need to go pedal to the metal to get all 130ft lbs of torque on takeoff? Does this system only activate after ess has activated (so turning it off means no etorque components are in play)


Another feature I've heard of is regenerative braking. I get the impression that this is actively slowing the jeep down during braking and may even be activating while coasting. It would be nice to know when this is activating and when not. Do I need to keep my foot on the gas just to keep etorque from activating the regenerative braking system.

Because the etorque system is discharging and charging by collecting wasted energy from some other systems, using it to the fullest extent on takeoff should be a way to improve mpg usage in city driving and disabling it during long highway cruising could also potentially help improve mpg but aside from some marketing bs on the window sticker this system is completely undocumented.

It seems like if you could bring up a gauge for the etorque battery level you could see some indication of discharge / recharge cycles and learn a few things from that. It would be great to have some controls to request more / less torque generation if that's actually a thing with this system.

If you want to geek out over the etorque system here you go

It add 90lbs torque from a stop, it has a double belt system. You can disable etorque like you would with ESS. You can browse to the cluster and look at messages and the system will show you if it's charging, you can do this at a stop light etc. Off-road pages will show you the main battery. From a stop my JL launches and wicked fun

"Maligned when first introduced to the public, engine stop-start systems save fuel by turning off the engine when it would otherwise be idling and using fuel, such as when waiting at stoplights and in bumper-to-bumper traffic. The first systems were not well-liked because they were often clumsy and slow. But in the eTorque system with 48-volt power, engine stop-start operation is smooth and almost undetectable."

"The reason it works so well is its added power versus that of a typical starting battery. For engine restarts, eTorque sends up to 90 lb.-ft. of supplemental torque to the engine crankshaft to fire up the engine again. Torque to the wheels travels within 400 milliseconds, more than twice as fast as in the typical engine stop-start systems that use a conventional starter battery."

"The battery pack array includes a 3-kilowatt direct current-to-direct current (DC-to-DC) converter that changes 48-volt current to 12 volts. This enables it to power the vehicle's accessories, which run on a typical automotive 12-volt current. Also, it allows it to charge the vehicle's conventional 12-volt lead-acid battery."

The battery packs can't handle much more than that, I reckon.

Etorque makes ESS almost seamless. Other than that, just forget about it. You can’t do anything to make it work differently. About the only other use I have heard of is tapping into the battery to get 48 volt power to aftermarket accessories.

There’s videos on YouTube. It might be Ram videos. And iirc, I think the 2.0 is 90 ft lbs and the V6 130? It’s been almost 4 years since I dug into this here and shared some info I found.

I can not tell virtually any difference in off the line torque when driving similar equipped wranglers (one with eTorque and one without). It last for 1/2 tire rotation? Is that even noticeable?

If you disable the ESS, it is about the same as a regular 3.6 without the extra weight.

Interesting video. He says it can’t be shut off completely or permanently. He obviously doesn’t have a Tazer from Z Automotive. LOL.

eTorque also makes for smother shifts, as the BSG motor keeps the engine speed optimal during shifting. Our 5.7 Wagoneer has it, and it's a very smooth operating system.

The eTorque BSG motor is mounted on the engine in place of the alternator. There is no supplemental electric engine/torque converter like the 4Xe.

Since the stop/start is powered by the BSG and the 48v battery, there is no need to disable it like the aux 12v battery ESS models. The aux 12v battery has become quite an issue with those, and the reason so many want to eliminate it. The eTorque's BSG starts the engine more quickly and smoothly than the ESS system. the eTorue only uses it's conventional starter when the engine is first started, and then uses the BSG for stop/start events.

I owned both versions of the 3.6 in a 2018 JL and a 2021 JL (each for about 40K miles) and have noticed a big difference off the line, much smoother shifting, and seamless ESS with the eTorque version.

I have a 2021 JLUR bone stock with factory Falken MT's. In the 3 years I've had it and the 18K miles I've driven it, 99% city/suburban driving and 99% same old boring route, my over all MPG is 17. And it's the same average whether I've used auto stop/E-Torque or not. Mileage isn't affected in my experience. A year of never turning off auto stop and a year of always turning off auto stop and the rest was whatever the system does on its own, as designed. Currently I just don't think about it anymore.

What I hope is happening somewhere is someone is designing a deletion kit for the E-Torque system. So in about 5-10yrs when warranties are up and the system ages and possibly has issues, us owners can start deleting it back to a conventional alternating system.

Engine braking from it too. Hopefully saves some brake life.

Yeah, but pretty sure that there is no regenerative braking system like a 4Xe or other hybrids. The BSG just slows the engine in certain situations when the foot is off the throttle or on the brakes.

I can, I have a 2d so perhaps its more noticeable. I test drove all 3 in a 2D, and decided on the 3.6w eTorque . I dont do diesels so have no reference on those.

There is brake regeneration in this system. It's somewhere in the owners manual too on that regen
