What are your best practices for maximizing MPG?

What are best practices for getting the best MPG?

I was on a long road trip last week and flipping through the UConnect Apps. I found the Hybrid Electric app and noticed the button for eSave. When I selected the eSave button there was 2 options. I selected “charge battery while driving” and then my battery charge level started increasing (about 18% an hour). Before this my battery never charged more than 1% while driving.

After getting the charge up to 80% I decided to select Electric mode until it ran down to 5% then into Hybrid mode for a while. The MPG between the Hybrid mode and the eSave mode seemed to be about the same, but I was able to add a few MPG when I ran on electric.

So does it make sense to run on eSave for a long road trip and then use the Electric mode?

Another question is how does Max Regen on (or off) affect MPG?

Lastly, I read the 4xe addendum manual and I didn’t see any information about how to optimize these modes and settings. Jeep should update it with some tips to optimize MPG.

For long trips just drive in hybrid. If you really want to maximize, use esave hold and save battery for traffic, then switch out once you are moving again. You get more range in low speed driving vs higher speed. But thats maybe a difference of a few miles versus hundreds total on long road trips. E save charge uses the engine to charge the battery so you are inefficiently burning more gas than needed, and what gets added back in charge. Like you posted above its also slow at highway speeds. It's worked best for me between 45 and 50 mph, but that was to have some battery when I got to my destination, not to save gas. Max regen is all about feel. Its great while doing city driving when you have electric range. At highway speeds, if you dont get the pedal feel right, you can brake more than needed and actually use more energy just getting back up to speed than if you just coasted and let the engine shut off. Typically I just use max regen when I have charge for city type driving and turn it off for highway drives. My best advice for maximizing mpg in general, is just do all of your low speed around town driving in electric. The less the engine turns on the better.

Jeep will never post about best tips. The lawyers will never let that happen. Too may people already wanting to sue over stupid stuff.

My esave charge doesn’t work for s.h.i.t. I get 2-4% over an hour of driving on flat land at 55-70 mph. I don’t even try anymore. For <50 mile trips mostly highway I just use hybrid. For >50 mile trips lots of highway I switch between hybrid and esave using mostly electric at low speeds. My use also changes between hot and cold weather cause climate control spends a lot of battery so I maximize when I can get help from the engine efficiently

Precisely this. There are inefficiencies in using e-save charge to charge up the battery just to then use the battery at highway speeds. I use e-save charge now and then toward the end of a larger trip so I have a little battery for around-town stuff, but it's absolutely not worth doing on a longer or higher-speed drive. Charging the battery with your engine is the least-efficient thing you can do.

Thanks for the response.
