Wow , I just ordered a 2021 Rubicon last week and had no idea really what the etorque option was until I read this. Should I be nervous or do most believe it works well and I'll be happy? I currently have a 2016 Sahara with the V6. Will I notice much difference?

I'm very happy with every feature in the system.
Auto start is less noticeable than any other vehicle I've been in.
The torque push you get @ takeoff is worth it just for that reason alone.
I'm currently getting around 18.4 MPG in my JLU V6 e. with stock everything.

Jeep Wrangler eTorque Mild Hybrid Technology
The 2019 and 2020 Jeep Wrangler sports two engine options featuring their new eTorque Mild Hybrid Technology, which offers better fuel economy and improved towing capacity.
What is Jeep Wrangler's eTorque Mild Hybrid Technology?
New 2019 and 2020 Jeep Wrangler has an innovative eTorque Mild Hybrid system that has improved fuel economy without sacrificing power, torque, or capability. It requires no additional effort by the driver and is part of both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine.
The new Jeep eTorque mild hybrid system is a replacement for the traditional alternator. It sports a belt-driven motor generator unit that executes several different functions.
How Does Jeep Wrangler's eTorque Mild Hybrid Technology Work?
A 48-volt battery pack works with the motor generator to create:

• a seamless start/stop function;
• a short-duration torque addition to the engine crankshaft in particular driving conditions; and,
• brake energy regeneration to increase efficiency and responsiveness.

When the engine is running, eTorque's motor generator unit delivers 48-volt current to a 430 watt-hour lithium-ion Nickel Manganese Cobalt (NMC)-Graphite battery. The battery pack includes a 3-kilowatt DC-to-DC converter. This holds the battery's charge and converts 48 volts to 12 volts so that power can be use to power Jeep Wrangler's accessories and charge its conventional 12-volt lead-acid battery.
About the size of a small suitcase, the air-cooled battery pack is mounted to the interior rear wall of Jeep Wrangler's cabin. The battery pack's case is insulated to hush the noise generate by the dual cooling fans. Cooling air is then drawn from the vehicle interior and released through the built-in cabin exhausters.
Because of its greater efficiency in extreme temperatures, both the 3.6L Pentastar V6 engine and the Turbocharged 2.0L I4 engine with Jeep eTorque technology will keep a traditional 12-volt starter motor, which is ideal for cold starts and the initial start of the day.
Beyond spinning the engine for restarts, the Jeep eTorque also recaptures energy during deceleration and braking to recharge the battery pack. Further, eTorque also bolsters the driving experience of the 2019 and 2020 Jeep Wrangler with additional torque to the crankshaft during gear changes, which minimizes noise, vibration, and harshness (NVH).
Both engines sport a liquid-cooled Jeep eTorque unit mounted on the front of the engine, which uses a pair of belt tensioners to ensure that the 8-rib drive belt stays tight when the unit is generating electricity or adding torque to the crankshaft.
With the eTorque Mild Hybrid system, the 3.6L Pentastar V6 engine boasts 285 horsepower and 260 pound-feet of torque. Maximum torque arrives later in the rev range, at 4,800 rpm. The Turbocharged 2.0L I4 engine generates best-in-class 270 horsepower, 295 pound-feet of torque.

This is something that can't be turned off by a button on the dash correct? It just works all the time right?

I would respectfully disagree on the eTorque generator being air cooled on the 3.6

My 2020 has 3 coolant reservoirs. The forward most one, in front of the windshield wiper fluid, has a line that goes directly to the front casing of the eTorque generator.

Agree - pretty sure eTorque units on 2.0t and 3.6 are liquid cooled. The eTorque in Hemi is air cooled.

You are clearly someone who doesn’t spend much time sweating reliability issues. And good for you. That’s probably the best way to live. I’m not being sarcastic here. I mean that.

Aside from the 4Runner, there’s not a proper 4x4 you can order right now that makes me particularly comfortable from a long term reliability standpoint. The Bronco has DI and turbos on both engines. Jeep has a DI turbo, an Italian diesel, a brand new 4xe, an eTorque V6, or an under-developed manual transmission. Choose the form of your destructor!

And let’s not even start on the new Defender.

I own a CJ-7 too, so that should tell you how important reliability is to me.

Just kidding. I think a lot of ppl are ignorant of just how reliable modern vehicles actually are. It's laughable how many people are experts in things that they have no clue about, and have never owned or driven.

Most people believe that it functions as intended when its new. The argument is that its a problem waiting to happen. Its a complicated system, controlled by a computer, that provides minimal to no benefit other than lower federal emissions and will almost certainly fail as the vehicle gets older. Jeep people want a simple, rugged, reliable vehicle that is easy to self maintain. The eTorque system is the exact opposite of that. It has no business being installed on a Wrangler.

The Jeep you're speaking of has not existed in 50 years.

The EV market will grow, and service all those with short commutes who aren't worried about road trips, and who can afford the chargers, etc. But then it will slow significantly, because there are many who want to be able to drive for more than one "tank" and only have to stop for 10 mins or less to "refuel". When EV's can stand on their own merits against ICE's, there won't need to be tax incentives to do so or laws trying to ban ICE's.

This is the real place for EVs in our lifetime. There are a lot of multi-car families in this country, and pretty much all of them have at least one vehicle that is a "commuter"...a perfect place for an EV to fit. Something that does 30-70 miles each day, then can be parked in a garage and charged slowly overnight. That's the most attractive case for an EV because it would offer the best fuel savings and have almost no downsides at all. Said family would still have another gas vehicle or two to use for longer range trips.

One short term solution I've heard is standardizing battery packs. You drive into a station, your low battery is swapped for a full one and off you go. But that still takes a lot of development and logistics to even figure out how to do. Not to mention once battery tech changes the standard battery size or charging might change and now you have to tear all that up.

It would take as long to standardize EV architecture as it would to upgrade the US electrical grid. Add to that the fact that all those stations swapping out batteries would still need to charge them and you basically have all the same problems. You're really only solving the charging time issue.

I agree that a commuter car is the perfect place for EVs and hybrids. I will make every effort to avoid buying an eTorque Jeep. On the other hand, if I could get the full EV Magneto with the 6 speed for a cummeter vehicle that would be an EV worth drooling over. There is a simple beauty to that machine.

Good comment about the stations needing to charge all those batteries they need to swap. How many cars go through a gas station on an hourly basis? Now multiply that by 10-12 hours for estimated charging time. Thats going to require a large building to store all those batteries. Thats a lot of overhead. They would also have to build into the cost of their service the fee to dispose of and replace dead batteries as people drive in with defective batteries. On top of that they will likely require their own 'techs' to swap them out. So now you can add another service fee on top the cost of the fresh battery. My guess is that you wouldn't be able to swap out a battery for less than $200 per stop in todays dollars. I would also expect waits to be approximately 1/2 hour up to 2 hours depending on how busy the charging station is.

The more I think about a battery swapping system the more drawbacks I see. It starts to look easier to build an entire new infrastructure and find a way to get enough current to a battery so it can take a full charge in 1/2 hour. I don't think that is physically possible.

How many years has eTorque been offered?

Since 2018 for the Wrangler.

eTorque is just the brand name for a 'Belted Alternator Starter' which was first offered in 2007 according to Wikipedia. Mild hybrids were first offered in 2005.

The 2.0's intercooler is smaller in physical size due to liquid cooling. Turbochargers require cooling of the bearing and shaft assembly that sits in between its exhaust and intake turbine housings. This is traditionally done with the same motor oil that also lubricates it. The one hitch in the giddy up with that, is the high potential of oil "coking" on the bearing which leads to abrasive carbon buildup. Motor oil cooled turbos should always be allowed to idle before shutdown, especially right after a spirited drive, so that the oil continues to flow and cool down the turbo bearing. I'm rambling enough as is, so I won't go into the different affects of fossil vs synthetic oil. I'll just finally wrap up with that the antifreeze-cooled turbo avoids "coking" and coolant is more efficient than motor oil when it comes to heat absorption.

So much good information in your post. I learned how modern engineering avoids the carbon build up with antifreeze cool turbos. And how more cooling lines keep these hot engines cooler. Thank God for modern engineering otherwise we would be still driving the original v6 3.8 mini-van engine.

Also anyone who is driving any version of the JL is driving a computer with complicated electronics. So when I read "I want a simple Jeep to fix"... I laugh & because unless you are a computer programmer you ain't fixing these modern Jeeps with your wrench... most of the problems with the new JL are with the electronics and computer systems not the mechanical parts. So if you want "a simple jeep" then don't buy a JL. And stop lying to yourself... The most basic Jeep (wrangler) worth buying is still the 4.0L TJ and older. Everything else is complicated.

If you got a computer screen in your Jeep then its complicated.

And I will respectfully accept that straightening out. My 2.0 etorque generator also has the same coolant lines that you described. I'm comforted to know that the unit is liquid cooled, which will shed heat more efficiently and stand a better chance against time. Thanks buddy!
