Thank you, great explanations and now I understand 🙏can it really go nearly 25 miles on electric only

The hybrid does a lot better with varying speeds and lack of NEED to run the Atkinson... i.e. if you aren't using AC or heater when it's cold.
Rolling hills are great - power up, recharge down.

About the only time I've seen the engine vs motor equation result to be very engine heavy is with sustained high speed interstate travel with a set speed cruise control.

As was noted, electric only is limited in range to a mile or so without any regeneration putting power back into the drive battery.

The way you drive the hybrid makes a huge difference. After using the hybrid coach, I'm hitting 100% recovery 95% of the time. It makes a big difference over the course of a tank.

I can't say for sure if it's accurate cuz I don't have a hybrid, but you went 28 miles and got 14 on electric which is about 50% and if you look at his numbers he went 50 and got about 25 which is 50%. So at least as far as that goes it makes sense.

But I am also curious as to what the answer would be.

Well, that seems a bit much but maaaybe in a perfect situation where you're speeding up and slowing down gently like in rush hour traffic on an urban freeway. I experienced something like that once coming home from a conference in Chicago and when I parked I was shocked at how good the milage was, perhaps almost a third electric for 40 miles. The Mav never got a chance to fully warm up because the ICE wasn't on that much.

Yeah. When I'm trying to get 100% I'm surprised at the drivers behind me trying to race up to the red light.

Weight, aerodynamics and engine.

It's a shame the 4xe has turned out to be such a turd. It's a strong idea and if they'd pulled it off better, the phev Gladiator would probably be out by now. And then we'd be off to the p(ickup)hev races!

I believe I heard Jeep was discontinuing the 4xe

 

[Deleted User 24227]

Yes it's possible and you're looking at it. The battery will regen as you go and provide electric propulsion whenever possible. That includes pure battery power and electric assist to the ICE, which reduces fuel consumption. A fully charged HV battery will get you 1-2 miles before depleting enough to start the ICE engine.

I can believe the mpg on such a short drive but it's the longer ones that make me go hmm lol

Maybe they were in the Army where they were trained to "hurry up and wait".
In a city, people always seem to be in a hurry.
I don't miss that at all.

Like I said: turd.

You can get those great mileages on the longer ones because 10-20% of your drive might be at 100MPG and the highway part of it is at 35MPG+ if you don't have a lead foot. The bottom picture is half local roads and half interstate.

Just in case it hasn't been made clear:

The hybrid is not doing those electric miles continuously. That's the big difference between it and a PHEV. The original image says that out of the 50 miles travelled, 25 of those miles have been with the gas engine off. Some of that is going to be during braking. Other times it might be cruising at steady speeds. If you're gentle on the go pedal, it'll certainly be when you're taking off from a stop, provided the battery is juiced up.

I've got just around 650 miles on my 26 Mav AWD hyrbid (picked it up about 3 weeks ago), and my trip 2, which I reset to zero when I drove off the lot, shows about 45% of my miles are electric. Most of my driving is city, although there's a few longer 40-50 mile highway stretches in there too.

You are correct that the hybrid doesn't have as much of a benefit in a pure highway / steady speed scenario.

Jeep 4XE gets ~20 miles EV only. Maverick gets ~2 miles EV only.

As stated, a full trip has many on/off instances with the battery being recharged between use. If Jeeps have a trip report have someone screenshot it for you. Probably will show similar if not better numbers.

 

[HeyBales]

You seem to be thinking in PHEV stats.

As above post states - not all at once.
That 25 miles EV was 500 feet here, 200 there, another 100 ft coasting down, in traffic so another 25 ft accelerating.
Each distance separated by the ICE turning on and providing power and some recharge.

That's a combined total - not EV used up first, with gas used second.
It doesn't work that way.

My 28 miles yesterday were about 20 hwy, 5 in traffic

i have a similar commute. 24 miles round trip with 16 hwy 8 city and i average 50%. i took this pic just as trip 1 rolled over to zero at the 10k mark.

 

[Mavster Mechanic]

The image isn't mine I just saw it on the forum but I was questioning the accuracy of the display yesterday on my Mav after driving 28 miles and 14 of those showed as electric? I know I'm missing something, the Jeep E plug in gets about 20 miles on a charge, this isn't a plug in and it's getting more??

So did you get your answer?
Stay below 55 MPH and you can go 1 mile on gas 1 mile on electricity only, 1 mile on gas, 1 mile on electricity only.

Repeat indefinitely.
Now why would you want to?
Thermodynamic efficiency is why.
If the gas engine is running full time your engine quickly reaches 180°F then extra heat is wasted. Waste heat is pumped to the radiator and dumped into the atmosphere.

By doing the 1 mile on / 1 mile off my engine might stay 170°F and the radiator fan (electric) may never come on in an hour of driving. Less waste heat. Less waste.

This works well when at low demands.
During the 1 mile of engine on, it propels the vehicle AND recharges the battery at the same time; in a highly efficient power band.

No free lunches here.
Just better efficiency here.
Less waste here.
My best commute was today.

Not a fluke. I can do this any day, on almost any road. Note 521 miles and my tank is still one-third full.

Days with no heater or air conditioner needed helps. A lot in fact.

This person was likely driving in lower speeds in either stop and go traffic or steady low speeds that allow the engine to maximize hybrid mode. I suspect he was remaining in hybrid mode for 1 mile + stretches where the engine was only needed to to charge the battery periodically.

 

[sprubs]

I would basically look at that number as "reclaimed miles" that were used. My rav4 prime on the other hand actually has EV range. if it wasn't bad to not run the ICE for long periods of time I'd be able to EV only in that thing 90+% of the time because I'm often only driving ~20 miles round trip and the EV range is generally over 40 miles, sometimes 50.
