Yes; but that would not the be same as having 370HP and 470TQ "all the time" which is what has been said here numerous times and suggested on Jeep's website.

It may well be that I have an issue with mine (at least I hope that is the case), because otherwise, the GC is a large vehicle to have "only" a 2.0T powering it.

No ICE drivetrain is anywhere near it's rated peak power "all the time". The 2.0T makes peak hp at 5250rpm, so you'll only be at that 370hp number for a couple seconds before a shift. The torque curve is much flatter so you'll be close to the 470ftlbs from 2500-5k. The fact that you originally stated it only feels like it makes that power with a charge and in hybrid or electric only mode tells me you're expecting EV like power output at any rpms with 0 regard for the limited powerband of the gas engine and/or there's something wrong with your GC. In electric only mode you're nowhere near those numbers as the electric motors only produce ~134hp and 180ftlbs. It shouldn't feel anywhere near the power output of the 2.0t alone in electric only mode. Do you monitor your input power when charging? If so, like most you likely never see more than 15kWh to charge from <1% to 100%... in a 17.5kWh battery. Short of very specific driving conditions where there's 0 braking, 0 coasting, and 0 deceleration the battery will never get to 0% and you should always have the electric assist.

Well...there was something wrong with it. There is a national recall out for it, and I think it affects certain Wrangler models as well, where the hybrid system would shut off and go into limp mode because it "thinks" it was in a wreck. The 2.0T does not produce 375/470 by itself no matter what RPMs it is running, so the electric is adding to it to gain those numbers, else Stellantis is (gasp) falsely advertising its specifications.

With that said, what I have concluded is that the opinion stated here more than once, which is, with the 4xe "you have the full power all the time," is bovine scatology--in line with what you just said UNLESS there is a dramatic design difference between the GC and Wrangler 4xe systems. Even after the recall was done, it performs much better, but having had many vehicles with the stated HP/TQ (and even higher), it is likely closer to 300HP and 375TQ "all the time" which is respectable, but not what is stated.

Not sure where you pulled your numbers from, but are you saying the electric power is always available but only adding 30hp and 80ftlbs to the 2.0t? Is your GC quicker than your Bronco? How do you explain the 4xe beating the scat pack on the drag strip as even at Jeeps full rating the scat pack should have almost 100hp advantage while being lighter? The guys 8.8s 1/8th mile equates to an estimated 375hp in a 5k pound vehicle. Seems to track? My 4xe wrangler experience was only 2 weeks in a rental but I am hard on things to start and even worse in a rental. I felt no power difference between a full charge or <1% on the display. That tells me the electric motor was still contributing.

Wife's driving the 1st leg of this roadtrip so I had time to answer my own question. 2.7L Bronco 0-60 is 7.3s with 325hp and 400 ftlbs. The 4xe does it in 5.3s and a claimed 375hp and 470 ftlbs. Either the Ford is over rated or the Jeep is under rated by the performance in the real world.

Considering the 4xe gc blows the doors off the hemi gc, I'm more thinking your butt dyno is off. That said it does require the right combo to unlock full power, engine on, 4hi auto engaged, but if you're driving it in the right mode its definitely got more grunt than 300 HP and 375lb ft. Now if you are trying to compare it to a car thats not going to work as the 4xe are probably twice the weight, have more parasitic loss with transfer case, and usually are rolling on bigger heavier tires.

Which numbers? Jeeps or mine? It matters not, what am saying is IF it is actually producing 375/470 it's the weakest example I have seen/experienced.

Though I have not placed it on a dyno (and won't), I know what 355/433 feels like and this is not that so it could be the GC is not the same as the Wrangler.

Don't know and don't care at this point now that the hybrid system seems to be sorted--Stellantis just needs to pay for 53 days of rental car.

Everything from 1/8th mile time demonstrated in the real world to 0-60 that destroys the Bronco with only 50 less hp and 80 less ftlbs by 2 full seconds screams their numbers are accurate if not under reported. The 5.3s 0-60 is the time for the GC 4xe. Even the 5.7L gc took 6.1s 0-60 from its 360hp and 390ftlbs. Not sure what your 355/433 comparison is, but the 4xe gaps anything I can find with those power numbers.

There are numbers and reality...they don't always line up and definitely do not based upon my experience. All is irrelevant at this point...I have 27 months to go...before I walk away from Stellantis permanently...unless, of course, it eff's up again and then they can buy it back under the CO lemon law.

Go back the Bronco forums troll. 375/470 isn't going to feel as fast in a 5300lb luxury SUV. The issue for the recall doesn't just shut off the hybrid system, you lose all motive power when the fault occurs. My GC 4xe feels like it has all of that for how heavy it is, especially when overtaking

 

[morph860]

We have a GC 4xe and a Wrangler 4xe. The only real difference I've noticed is that the ICE kicks in "easier" in the GC than it does in the Wrangler and it's not as obvious or loud in the GC. The GC is a smoother ride as expected. Our previous vehicles were a 2.0T Wrangler and a 3.6L GC. The 4xe's both have substantially more power.

it does not feel like 470TQ except on full electric.

When you say "Full Electric" - do you mean only the battery running and the ICE is off? If so, you're not going to see anywhere near 470TQ like that.

Sport mode is the only thing that comes close. It does have good power in sport mode, but 375HP and 470TQ are not what I am feeling, and I have driven enough high HP/TQ vehicles in my time to know.

It's a nice vehicle, and while I know it is not a sports car, it just doesn't feel like it has the advertised power. So, unless there is some magical combination of settings that I have not discovered, and I think that I have tried them all, I am not seeing it.

Having had the recall performed, I can definitely say that you do not know what you are talking about. It ONLY affects the hybrid system--the engine will still run, and the car is still drivable.

Considering the contributions that I have made to this forum, I am hardly a troll--what have you contributed?

Well...since it has already qualified as being a lemon, maybe it is just that. It appears to be just my luck with Jeeps...

Have you driven high horsepower trucks and SUVs or just cars? I've had plenty of both and it makes a huge difference in the butt dyno since that seems to be what you're going off. Unless yours truly is broken (unlikely given the massive amount of sensors on these), you probably just expect car performance from a large SUV which just isn't going to match up at all. Simple things like sitting closer to the windshield and sitting lower as well as actual seating position all give a different impression of speed. The only real way to know if yours is a lemon is to get some accurate performance numbers and compare.
