eTorque Description

[silverooby]

In case I'm not the only one that never paid attention to what eTorque is, here's an explanation. I bought my JLUR in 2022. I noticed on the feature list that it had eTorque, but never got around to investigating what it was. Since then, I've seen posts with people complaining about the 3.6L being underpowered. It never computed to me because I've always had plenty of uphill passing power and great acceleration. Then one day, I tried to pass two cars at a time and a little ways past the first one, I noticed a significant loss of power and barely made it around the 2nd one in time.
Long story short, I discovered that the eTorque is a mini hybrid system that stores energy in its own battery and provides up to 100 lb/ft of torque through an electric motor belted to the crank. But, the extra torque only lasts for about 8 seconds, which is enough to blast past one car, but not two. So, if you have eTorque and weren't aware of how it worked (like me), be careful.

Here's an explanation.
Who are you people that buy stuff and don't know what they purchased?

Not quite the same since it's the RAM engine, so there is extra stuff in the CPU for towing and cylinder shutoff. The JL 3.6L e torque doesn't do those things.

You primarily feel the extra torque during initial acceleration and slow speed manuevers (off road). But you do feel it if you are on the highway and slam on the gas to get around someone. Even in the video, the guy didn't say you WOULDN'T feel it, just said not as much benefit as other areas.

I feel it when I have to MOAB bump something off road. It's awesome.

IMO..just another expensive item, to satisfy the Feds. Fuel economy being their main goal!

I agree that was the main driver behind developing this, but this is one of the rare times I think there is a desirable bi-product: extra torque when you want it most.

I love my e-torque. Having said that, are you sure you didn't hit the speed limiter? I can hit 98 mph in no time and it feels just like you described.

I am pretty sure no etorque additive except first half a wheel turn from a stop or crawling slow speed. You dont get a kick from it while doing 65. From other readings, it only adds torque to the amount the engine could provide it at a higher rpm, but you will never see full engine torque plus full etorque add. It blends in and fades out as engine accelerates.

That's what I understood as well, and was confused by what @silverooby was claiming.

I've been driving this Jeep for almost 3 years putting over 60K miles on it. I can testify that I do consistently get a huge kick out of it going 65. I'm never afraid to pass a car going uphill. What I posted is what I read about it, but I'll do some more research. I don't think I hit a rev limiter. I would have expected a surging action if that happened.

If you look at the torque curve and information from the engineers that designed this, you will find that the torque increase is only at initial take off from a stop for about half a wheel turn. I have the 3.6 etorque. Something else is causing the sensation you’re attributing to the etorque system.

OK, this video settled things for me.
Seems that the information I got beforehand was bogus. Verified that etorque only works at low RPMs. I see a lot of comments on this board about the 3.6L being short on power. I seem to get all the power I need, so I don't understand that part. Anyway, sorry for the bogus post.

That’s why we’re all here…to learn. Many people wouldn’t handle posting mistaken information as well as you did, so good on you.

Thanks for the info. I've been intrigued by the e-torque ever since I was "introduced" to it by a few members here. Some on this thread are claiming torque assist for only a half-turn of the wheels or so, but I have to believe it's at least a few more seconds. Even the dead start effects of my 4.88 gears and low 1st gear last longer than half a turn of the wheel. I need to learn more.

I bought my '25 JL last Feb 28th with a build plan already laid out. That involves eventually dropping in another LS V8. I sure wished I knew more about the e-torque before finalizing my plans. Maybe next time.

That’s the same video I shared in ‘19. The thread is buried here somewhere. That and another drive-along with an engineer.

Not the *rev* limiter, the *speed* limiter. 98 mph is the maximum speed our Jeeps can go. They don't sputter at the speed limiter, they just stop going any faster.
