It's a turbocharged 4 cylinder. Very peppy. Plenty of info/road tests/ etc. etc.

Running on 4 cylinders
I currently have a 2014 V8 GC Overland and love it, but it's getting old. I'm very interested in getting the 4xe next year, however, I have one serious concern about it that I hope someone can shed light on. My question is how well does it drive when the battery runs out and all you have is a 4-cylinder engine? The GC is bad enough with the V6, and I can't imagine any 4-cylinder in the world capable of moving such a large vehicle. Does anyone know how this is going to work? 0-60 in... next week?

Even with dash showing less than 1% charge, in reality vehicle always runs as hybrid so the ICE will keep battery charge available for full access to power and torque.
Wow, bossboy, I come here for advice and that's your response? Very mature. Maybe you can help me with this "big word": uncouth.
Anyway, I've done plenty of Googling for an answer to this over the last few months, and I've watched almost every YouTube video out there. Nobody, and I mean nobody ever talks about what happens when the battery runs out. I've seen posts about what happens when the gas runs out, but not the battery. Seems the press cars always have plenty of juice, and Jeep is sure to keep test drives short so it never happens.
Hybrid3.0, are you sure it's always running as a hybrid? My old Fisker Karma did that, but that was an EV powertrain where the gas engine did not directly supply any power - it only charged the battery. I thought the 4xe was a hybrid powertrain with gas supplying HP and electric supplying HP, no?

Corrrect! You’ll always have access to that extra power whenever you need it.Even with dash showing less than 1% charge, in reality vehicle always runs as hybrid so the ICE will keep battery charge available for full access to power and torque.

Your words.
When the battery runs out, it becomes a turbo-4 gas driven wrangler. Should be fairly obvious. Acceleration will continue to be aided by the e-torque electric assist. Also fairly obvious.
To answer your question, the 4-cylinder turbocharged engine with e-torque (for which there are many, many reviews) performs quite well.
0-60 in much less then.....a week.

I run out of battery daily and then run solely on the ICE engine only. It drives great. Plenty of power. I feel it’s not lacking anything for a nice daily driver without any battery power.
Well, bossboy, I don’t know why you feel the need to be so obnoxious and rude, but there is nothing obvious about it. That’s why I asked the question in the first place. The way Jeep describes the vehicle it has two separate power trains that are combined, so there’s no obvious answer to what happens when one of those power trains runs out of its energy source. There is no mention in the literature about the gas engine being able to regenerate the battery, or supply any power whatsoever to the EV system.
OK, so when the battery dies it really is only running on gas, right? The gas engine is no longer providing any charge to the electrical system? I’m kind of getting both answers here so I’m not sure which is correct.I run out of battery daily and then run solely on the ICE engine only. It drives great. Plenty of power. I feel it’s not lacking anything for a nice daily driver without any battery power.
When the battery shows 0% on the dash gauge, there is still 15% of battery capacity remaining. The 4XE system then runs in a traditional "hybrid" mode constantly sharing the drivetrain load between the electric motors and the ICE. The 4XE system will maintain the battery around 15% actual (although 0% will be shown on the gauges). Its a little confusing to discuss and further confused when you add in the 3 4XE driving modes of HYBRID, ELECTRIC and E-SAVE. All of these modes include hybrid operation.OK, so when the battery dies it really is only running on gas, right? The gas engine is no longer providing any charge to the electrical system?

We recently made two 650 mile trips (mostly interstate) with only a charge at the start of the trip. Once the battery shows <1% it prioritizes the ICE. However, the battery will continue to charge through regenerative braking and at times you will notice the battery level increasing.OK, so when the battery dies it really is only running on gas, right?

The extra torque of the battery drivetrain was always available for acceleration if needed.
Our previous Jeep was a 2019 GC Trailhawk and I feel the Sahara 4xe has better acceleration.
I'm not sure that the battery could ever totally become discharged.
Not running in electric mode is not the same thing as running on ICE only. If you watch your hybrid pages, it should show you consuming electricity when the throttle demands it.I run out of battery daily and then run solely on the ICE engine only.
Let's end this discussion. Here's video proof that when the battery is depleted (showing <1% SOC), the vehicle still delivers electric power to supplement the ICE:
When the bettery drops to 0 a small door opens under your feet and the Jeep enter "Fred Flintston" mode so you can power the Jeep yourself. 
That video finally answers my question perfectly, thanks!

Didn't watch the video yet and I think your questions have been answered, but still wanted to chime in:
The 4xe can operate as a parallel or series hybrid. The ICE and electric motors can power the drivetrain simultaneously, or the ICE can charge the battery with only the electric motors powering the drivetrain. The ICE can run the drivetrain, charge the battery, or do both at the same time.
Your Karma was a series hybrid, so only the electric motor was connected to the drivetrain. The ICE's sole purpose was to run a generator charging the battery.
In the Jeep even with the battery showing zero, you have some charge left plus the ability to run parallel, so you are rarely running just ICE for any extended period. It's always a combination.
I drive 100+ miles per day in my Jeep so my battery is on <1% all the time. It still has plenty of power. The gearing helps but the turbo 4 is a great motor, and even better with the little bit of hybrid power it still gets when the main charge is depleted.
I traded in a c7 corvette for this Jeep and I was fully prepared to give up the "spirited" driving. I've been pleasantly surprised with the power in this thing and having a blast ripping around town in it.
Agree @Horse_Power, low cg, 20 inch wheels/tires, high torque and short wheelbase make this a fun tossable vehicle to drive.

The 2.0T is a GREAT motor by itself. 270hp and 295tq. I currently have it in my 2019 Cherokee Trailhawk and chose it over the V6 option. It makes better power and by my estimations in talking with V6 folks, better fuel mileage as well. I was incredibly psyched to hear that not only was the 4xe coming out, but the ICE was the 2.0T? Awesome.
I use my Cherokee to tow a race car in an enclosed trailer.
If you told me that I could buy a 2022 Grand Cherokee, but there was no 4xe option, only 2.0T, V6, or V8, I would buy a GC with the 2.0T.

I've taken my 4xe into the Colorado mountains multiple times now - so think in terms of those long climbs and descents (well... sometimes the descents are faster than just "slow") and this is my experience:
1. I blow through the battery super fast headed into the mountain due to the topography.
2. Upon reaching the top of the passes, I am usually letting the Max Regen take over to control speed (this is on I-70 so moving down the road 50-60 MPH).
3. The ICE is working pretty good going up passes and when going down it shuts off and it takes a long time for the battery to begin registering more than just <1% - I take this as a sign that the "15%" reserve was being replenished and only when it is does it begin to register additional battery charge.
Why am I saying this? Because it seems to me that the jeep does in fact assist with electric the whole time I'm traveling from Denver to Avon. I've made about 5 trips like this and its the same every time. On occasion I do notice the engine running a little harder and I attribute that to full depletion of the battery. I've had this happen just a few times, though.
BTW, even with my mountain driving, my avg MPG is still between 32 and 36.

I plugged in some variables to a 0-60 calculator and was getting estimates of 6-7 seconds.
This seems to be further validated by the Automobile Catalog as they state:
When I asked the dealer about the Wrangler 4xe's speed, he said most people say it runs faster than the regular engine. I ordered a GC SR 4xe last week. Excited to see how it performs. I wonder if the combination of the electric and ICE power provides the best acceleration at low and high speeds.

I currently drive a 2014 Jeep Grand Cherokee Summit that I bought brand new and I take good care of it. It has the 5.7L engine and it struggles on the highway to speed past people. I was able to test drive a Jeep Grand Cherokee L limited with the V6 and it honestly felt even faster than my V8.According to the ProfessCars™ estimation this Jeep would accelerate 0-60 mph in 6.2 sec, 0-100 km/h in 6.6 sec, 0-200 km/h in 30.1 sec and quarter mile time is 14.7 sec.
