Can anyone actually tell the difference i power between the 5.7 and 5.7 with Etorque? Please post.

[Kramersp]

Just curious.

 

[Jus Cruisin]

I bought mine for the, in theory, fuel economy and the added torque for getting my car trailer rolling. It's not a supercharger. I doubt there's much difference in 0 - 60 times. Neither will be very fast.....

I drove both today. The E torque was a big horn Quad cab. The standard Hemi was a Laramie crew cab. The only difference I could feel was when coming to a stop. The E torque engine presented a slight bit of resistance without applying the brake. Starting from a dead stop presented no difference. Passing other vehicles on the interstate presented no difference. The E torque is either very smooth or does not add very much power. Just my opinion.

I test drove both. I should have checked the gearing on each to make sure they were the same. I didn’t. The newness of the etorque concerns me. The fuel savings amount to about $250 a year based on current mid grade prices driving 10000 city miles per year. You decide if that is worth the price. Lastly the battery in the cab sounds like a bad idea. All that being said I ordered an etorque. I felt there was a noticable increase in torque and throttle response off the line. I know others say not but it just felt like a better experience to me. Maybe the gears were different and I feel dumb for not checking that. It also seemed to eliminate MDS cylinder activation bog which happened twice in a 10 minute non hybrid drive. While non etorque does not have auto start stop the etorque made it the smoothest I have ever experienced. My friends f150 is jarring the way it shakes the whole truck when it starts. Etorque does not do that. I expect to save a bit more cause I have a heavy foot off the line. I feel this gets you going for almost free but who knows. It would be nice to have someone do a zero to 30 test and see.

So just to be clear, eTourqe is an assist for the start/stop function ONLY. There are no HP or bottom end gains to be had, there are little economy benefits to cash in on either.

I find start/stop tech to be a silly way for people that like the power of a gasoline engine to feel like they're contributing to the ecological efforts of the granola crunching leftist tree huggers. Makes my head spin. F-you David Suzuki!

But I digress, it IS all about start/stop. Maybe you'll save a few pennies a year in fuel. But if saving money on fuel is your honest goal... wow, what a foolish way to waste $60k. You should've bought a Prius.

Actually VadarRebel, it is mostly used to smooth out the start/stop but there are other benefits to it as listed in the below article I posted in another thread:

Forbes article - a lot of nice detail on the smaller benefits of eTorque besides just the smooth start and stop:
https://www.forbes.com/sites/samabu...orque-getting-mildly-hybridized/#31a4b96847e1
- Helps the engine stay in 4 cylinder mode longer
- Another interesting detail comes during shifting. During the brief intervals between gears on an upshift when the engine speed needs to be reduced, the BSG is used to slow the engine. The result is smoother, faster shifts while also capturing some energy. Conversely, when the engine needs to speed up on a downshift, the BSG can be used to accelerate it without using added gas.
- The battery helps with the power load on some of the electronics
- During deceleration, fuel flow to the engine is shut off more aggressively and for longer periods than it normally is on a 12V system because the BSG has enough torque to assist in turning the engine during transients when the vehicle might transition back to acceleration.
- With the limited size of the battery, when driving in stop and go traffic or down a longer grade, it can easily reach its charge capacity from regenerative braking. Rather than wasting the energy that can’t be stored, it is redirected to speed up the cooling fan and super-cool the radiator. Thus when the truck comes to a stop in hotter weather, it can act as a heat sink for the engine when it isn’t running, enabling longer shutdowns and better fuel efficiency.

If you have it's great - if you don't have it - its a waste of money. Just like any other option - on any car forum. Tech package, 4wd, sunroof, and on and on and on.

Agreed. I read a bunch of the eTorque reviews and articles - I get the feeling that RAM purposely started out real conservative with this mild hybrid tech. I think there are some regulatory hurdles if it was more then a 48v system. But with that being said I swear hearing one of the engineers at RAM mention in a video that this lays the ground work for more revolutionary benefits in the second or third year versions of eTorque.

 

[VaderRebel]

@BostonBlueRam , I know I over simplified the system, only to drive home the point that it's a very passive system. You're obviously more detail orientated than I am, but just wanted to dispel the myth that it adds horsepower or torque to the overall power of the truck. I agree Ram is playing it very safe with its first attempt at a mild hybrid system, which is why I had no interest.
Forgive my granola cruncher analogies, but admittedly I do find great humor in people trying to argue fuel economy numbers on a 400hp truck.

I will now back away slowly from a conversation I have no stake in.

 

[2019REBEL]

My brothers and sisters from the Fire Dept thank FCA that it's only 48 volts. Anything higher than that it gets nasty trying to fight it in a fire aspect and its a ***** trying to disconnect them.

 

[VectorZ]

My truck has the eTorque and it's in the shop right now for some some damage repair that was on the truck when I bought it. I have a 2019 Tradesman with the Hemi 3.92 as a loaner.

To me the non eTorque engine feels much stronger than my eTorque combo. It could be my Limited is larded up with a lot more weight with the bells and whistles, but I doubt it would make any real difference. As was pointed out I also have a harder time being smooth with the eTorque with the regenerative brakes. It's not jerky by any stretch, but I would go with the non eTorque if I were to do it again. But I do actually like the stop/start...

 

[Douglas31]

I agree with everyone else. My truck feels quicker than my 2014 Sport but I attribute that to the higher gear ratio on my 19 not the etorque. It does improve the stop start function significantly compared to my 2018 Grand Cherokee but the regenerative braking does sometimes annoy me when I am in stop and go traffic and I am worried about someone rear ending me when it slows down quicker than what I have control over.

According to my cluster, my truck (about 3500 miles) has spent 100 hours driving and 20 hours at idle. That's 15% of the time the engine didn't "need" to be running. That is a pretty dramatic figure. I didn't buy the etorque because I didn't want to deal with first gen problems, but there's no reason to think that this kind of system couldn't do a lot of good.

 

[3960]

I have the etorque and notice when getting on it fairly hard, it almost has a turbo like "kick" where it pulls hard right before it shifts gears. This may be a Hemi thing across the board (my first Hemi), but I did not notice this with the first non etorque Hemi I drove. Either way, the truck runs great and is closer to my 6.2 Denali than I initially thought. Could not be happier!

 

[Avid6eek]

I drove both and noticed no real difference. I live in Virginia Beach where 6 months of the year I have the AC on in the truck. Running the AC disables the stop/start feature, which is the primary method for increasing fuel economy. I doubt I'd ever recoup the $1600 expense of the eTorque and I'd have to deal with any potential problems it may bring. I ordered my '19 Limited w/o eTorque.

For those with e-torque, can you override the stop/start function, and does that 'setting' stay in memory so you don't have to continually turn off stop/start? For example, you get in the truck, start it up, turn off 'start-stop'....when you shut it down and then start it back up, do you have to turn off the auto start-stop again if you don't want it?

Yes you can override it, you just push the button when you don't wan't it to function. Once you shut the engine off, you'll need to push it again the next time you start the truck. I believe that ALL other systems from other manufacturers operates the same way.

 

[Rammit]

I’ve had mine for a few days now so it’s too early to tell. The truck seems a bit peppier thank my 2010 but not by much. I do notice a bit of assist during breaking, which I assume is the regenerative brake charging. The biggest difference is with the stop start function. I’ve driven cars that I cannot stand to use it on. This gets rid of all the shuddering and shaking that you feel with most systems. The stop start is almost unnoticeable. The real reason I got it though was for towing. I tow a 22’ enclosed car trailer from time to time. My current truck does a great job towing it but you do hear and feel it working at times. I have not used this truck to tow yet, but I am hoping the torque boost helps out.

 

[Biga]

I don't notice a big difference. I do feel a little more torque right off the line as the truck wants to learch forward for about a split second before I even give it much gas. Also I do notice some regenative breaking which should help with less wear on the brakes.

My wife has a 2019 Big Horn with non eTorque and 3.21 and I have a 19 Laramie with eTorque and 3.92.
Honestly, hers feels so smooth and light compared to mine. Although hers has almost 2000 miles already and mine is at 100. I’ll let it break in more and we will see.

Not too much of a fan of the regenerative braking. Makes the truck feel “heavy.”
