As someone who lives in a mountainous region, battery charge mode on long downhills has virtually no penalty and makes a ton of charge. It’s very useful, to the point where I fault the engineers for not making hybrid mode toggle battery charge on and off based on inclinometer data.

More often than not, if Iam using esave it’s because I over pushed it and the engine has started. Now that the ICE is running, I want to get the oil temp up to at least 195° to help evaporate off fuel that might get into the oil. Since it tends to be a bit cooler where I live, I will use battery charge to make the ICE work a little bit harder and reach that temp. Otherwise, I charge at home and at work. My commute is around 24mi round trip. With such a short commute, Iam probably using more battery power than most. I generally stay in electric mode, and only switch to hybrid when Iam going on a longer trip that will exceed the range. It made sense for me when I bought the vehicle in January, because I knew I would be saving a ton on gas, while still having the benefits of a Jeep.

We have a cabin in the mountains. When driving down, max regen is a game changer in our 2024 Willys 4xe. We can go for about 37 miles down without touching the brake pedal unless there is a hiker or animal crossing.

I agree with everything everyone said. I use Max Regen more as a convenience feature. On Highways it is definitely OFF, Mountains - ON, For coasting (also, Highways) - OFF. But, I do use it often to drive around the neighborhood and around town, because after a while you know how much it reacts to get the car to slow down. I think "Max Regen off" is probably more efficient and it seems to give me 1-3 KW when I am coasting, without me having to accelerate if misjudged. Great video.

Thanks for the great video! As stated, Max Regen is nice for downhills, but it's also nice to push on exit ramps. I look at it as braking assist with benefits! Also, I like to use the electric mode for accelerating to highway speeds (gracefully) before going to gas-mode (e-save) for cruising. Puts less torque/wear on the engine. Your worse MPG is usually during acceleration. Of course, the aerodynamic of a Jeep do not help much @ 70MPH

The battery charge mode is for when you have the power pack plug and you are using it to run appliances. In Max charge mode, if you watch the regen meter, light gas peddle is the same as coasting, you are not using electricity, its just not charging as hard.

I run electric exclusively for my local travel and usually run at least 150 plus a week on electric. As far as FORM, I haven't had that appear yet, but probably will at some point, I don't know. I have accelerated hard many times, but it has not switched over to gas when I do that, it just gets up and goes. I can say I haven't bought gas for over a month, so for us it works as we thought it would. A road trip will be a different story. Your video is good info to know, however. Thanks.

❤you are on point with all the information that you have provided and making it easy to understand I have been renting a 4xe jeep wrangler Sahara hoe to buy one soon Keep the content coming ❤

Great video! For me and my driving I find Max Regen gives me less battery miles and worse MPG. I run Max Regen off most, if not all the time. My 2024 latches on Hybrid and Electric but not on E-Save. Would be nice it it did all 3.

Thank you for the explanation on that. I have now subscribed you.

For me e-save button is a blessing , while i use it for charging my battery. Let me explain why, i drove 94 miles daily and I don't need to charge my phev for this journey too. I start my car and drive about 27 miles on ev and then when the battery is low it shifts itself to hybrid but i purposely shifts it to e-save to charge my battery while I'm cruising on highway where my car already gives me a good mpg then before arriving to my destination i engaged my ev again when it's fully charged so that the last 10 miles i have in city not highway i save fule and use electric which i generated while cruising on highway. This makes my life easy and i never needed to charge my phev.

Awesome vid, Awesome info.

I could see using E-save mode to save electrons for quiet time at the campground, arriving at your house at odd hours so your family doesn't wake up, or maybe run the Wrangler's inverter through the night while camping. (I'm sort of spitballing here) Do you thing Max-Regen would be handy while trailing or driving in the mountains? Can you recharge the pack some by toggling Max-Regen on/off?

For me the regen is useless,as someone said iff i lived on a steep mountain then maybe
