Just drove my Rubicon home and noticed the e Milage is not what I would have expected. After reading the manual, it says in hybrid mode the vehicle uses up the battery first then then switches to gas, which doesn’t sound like anything different than just running in battery mode and the jeep switching to gas when it’s gone. Anyone know what’s up with that?

In hybrid mode the battery/electric motor is basically used to get the 4xe going when accelerating, then the gas motor kicks in. While in electric mode everything is done by the electric motor.

my observations while driving in electric mode the ICE will not get engaged/started until the battery is at 1 to 0% or full throttle is applied for more than about 1 second.
In hybrid mode the 4xe prefers the battery but will start the ice above around 50% throttle and is more likely to engage/start the ICE as loads increase and even more so below 30% battery (for example a moderate hill with 60% battery hybrid mode does not start the ICE, but the same hill at the same speed at 25% battery ICE does start, and in my driving seems to stay on a little longer once loads / throttle is reduced before turning off, unlike electric which tries to turn of the ICE asap.

How do I tell how many engine miles I have? Breaking in to 300 miles could take awhile if it keeps running on battery. Maybe I should stop charging it during the first couple weeks.

As long as you don't drive in fully electric mode you should pretty much get 300 engine miles as you're driving from my understanding.

Hybrid used all the battery first. I know its not the same as the electric mode, but not different enough. Maybe I just need to start mashing the accelerator (once its broken in). Although, I'm only getting 20-21 mpg around town on gas.

It keeps getting more efficient as you break in the engine. My battery went down to zero about 8 miles from the dealership when I brought it home. It took about 2500 miles, but now my battery in hybrid mode lasts about 40 miles. I am getting avg 29mpg, charging only at night. I drive about 100 miles/day.

Completely agree, why even have a Hybrid button? I am currently getting 28 miles on electric but the moment I get on a highway I have to change to E-save. It is so frustrating that while doing 75 the battery just flies away and 20 minutes into the drive I hit traffic and am using gas for stop and go. The lesson is learned but I fear that when I continue to go back and forth from E-save to Hybrid as much as I do something is going to break. I would love for an update that once 40 or 45 mph is reached it goes into gas and if you don't want that you till have the electric button.

Why would changing modes break anything?

So in a nut shell the 4xE system is a joke
In a nut shell, people don't understand the 4xe system. They have misconceptions about how it is supposed to behave.


It's a series-parallel hybrid that is always a hybrid. When there is sufficient battery power, it behaves as a series hybrid, propelling first off the electric motor and augmenting with the ice as needed. When the battery state of charge lowers, it behaves as a parallel hybrid, augmenting the ice with the electric motor as needed. This is typical behavior of series-parallel phevs.

After 28 miles (or whatever you electric only range is), it is not dead, it just switches hybrid modes from series to parallel.

Well ... I wouldn't call it a joke. It depends on how you use it. If you're someone who drives to work say 70 miles, all highway and can't charge while at work then sure, you have 50 miles driving a beefy brick to work then 70 miles home. Once the battery empties out it's still there in the background like any other hybrid but pure highway driving, it won't help much if at all once you've used your initial charge. However, there are people who's gas goes stale before they could use it because they have a shorter trip and/or can top it off often.

To my understanding and from what I've experienced, as long as you are in 4wd auto you have access to the 375 HP and 470 TQ regardless if the battery is at 100% or less than 1%. The modes change the calibration of when the ICE or electric motor kick in/add power. In Hybrid mode with more than 1 % I can get to about half throttle before the ICE kicks in, Electric mode with more than 1% I can get to about 75% throttle before ICE kicks in, with more than 1% in E Save mode save or charge the ICE runs at most throttle positions. In all of these modes as well as when the battery is less than 1% you can/will get power from the electric motor as more power is requested. If you watch your Hybrid pages you can see that even at less than 1% battery the electric motor will add power when requested by throttle input.
