Blended Hybrid (M8) vs. Regular Hybrid (plus bonus content) 

I got the upgrade and insurance for it . They will replace it free ….

Now that’s awesome. Having a charger at work doubles the range.

You're right around the distance where the 4XE is still a logical choice. If you could charge during the day at work, that would make a huge difference. Even if it's just level 1 charging.

So, I have a 105 miles commute everyday, in flat highway on central Florida, on my 2019 mazda3 I get 27-28mpg, I’m thinking on a 4xe wrangler, in your experience, what average can I expect?

@@joegonz1983 Can you charge in the middle? For about the first 60+ miles, it gets around 30+ MPG. Now that’s a bit of a sketchy number because MPG alone isn’t accounting for the electrical energy used. After that initial 60+ miles, it drops down to around 21-24MPG. So if you can charge in the middle of that 105 miles, that would be alright. But the 4XE really does better for shorter commutes.

@@Wrangler4XEFans thank you. I think there is a charge station around work. I think it might work. Your channel is very informative, thank you!!!

Drives me nuts when gas stations use green boots on the regular pumps. I still think they should be diesel only.

I’ve often questioned that grill insert. I keep thinking about putting the stock stuff back for a month or two to see what it would do…but my laziness has prevented that. I’ve had it in pretty much from the beginning.

@@Wrangler4XEFans I'm putting one in this week. I'll let you know if my mileage changes lol

It won't charge up to or hold at 100% in Esave. It drops to 95%. As a side note, there's never a time when the 4XE runs in a gas mode. It's always a hybrid. And eSave is less efficient than the other modes. It burns more gas to try to charge or hold the battery. I have some other videos where I've done experiments with eSave and it always uses more gas.

@@Wrangler4XEFans The reverse of what SN is suggesting could work though. You could top off the gas and use electric only mode to get to the charger afterwards. That way you can be at 100% fuel and battery at the start of the future tests.

YES!!! All of that, YES!

Fortunately, gas has taken a nice drop in price. Just filled up for $2.99/gallon today in Yukon, OK. I believe Yukon currently has the lowest gas prices in the nation.

Esave is a mode you can select on the left side of the steering wheel. Esave either holds the charge in the battery where it is or charges the battery. Both modes come at the cost of using more gas. M8 is when you pull the shifter to the left and shift manually. In hybrid mode, it blends both the electric motors and the gas engine. People use M8 when the battery is charged to make the battery last longer. From an energy perspective, it isn’t any better than using up the electric range then going in to hybrid mode. But a lot of people have come to believe it’s better because the MPG calculator on the dash says it is. But if you calculate the electrical energy used and the gas used, it all comes out about the same. But in the winter, you can use the shifter to keep the engine from shutting off when you come up to stop signs and such. This prevents oil dilution from short engine runs. Putting it in eSave+charge will keep the engine on too but eSave uses more gas.

Mine very seldom gets to 100%. When it does, it jumps to 99% by the time I back out of the driveway. That percentage is a software anyway. The 4XE has a 17.5kWh battery but we only use 17.3kWh. So that 100% state isn’t really 100%.

@@Wrangler4XEFans thanks for the feedback. Just noticed it after about 4k miles and I wondered if charging it too frequently caused the issue. Also, I only plug it in if it’s under 60% since I’ve heard that charging above that puts more strain on the battery. Is this true?

@@EvilRubberBiscuit There is no documentation about that on the 4XE. Some people will apply knowledge to other platforms to the 4XE.

I let it click off once, let it sit for a few seconds and do one more click off while listening to make sure I can hear the liquid sound in the filler neck. I worked to make that consistent to make sure it was at the same level.

Me too.

Good idea.

@@Wrangler4XEFans thanks! I was looking to add pod lights and a lightbar but unfamiliar with how the 4xe electrical system is wired with the batteries

You’re going to make me do another experiment.

That would be an awesome video! (Sorry) I’ve found much over 70 mph kills gas mileage. But a good six hour video should be able to explain all that. 😀

@@steve337 Yeah, the consumption rate gets real non-linear above 70.

@@steve337 That’s the problem with some of these experiment…they are just time consuming.

@@Wrangler4XEFans engine rpm makes an absolute HUGE difference in fuel economy. Case and point, I had an 18 Silverado 5.3 and during commutes to work I would get 15-15.5 average mpg (lifted with off road wheels and tires) however when I towed my boat my average went up to 18.3-18.5 consistently. Even with the extra weight, the difference in rpm from 55mph(towing) to 75mph(commute) was enough to see a major difference in mpg. I believe it was close to 600rpm difference.

In M8 mode, it will still use battery power if it’s in Hybrid mode. It’s really the only way to force a blended hybrid mode in the Wrangler 4XE.

When using the blended hybrid function that M3 creates, you’ll get a little over 30 MPG for the first 60 miles. After that, it will drop down to 21-24 MPG.

Esave+charge will push the MPGs down hard. Like 17-18 MPG. The MPG calculator on the dash won’t show that it’s going that low but a real world calculation at the pump will. Esave + hold is less efficient than just running in hybrid mode at

@@Wrangler4XEFans Thank you so much, My question is whether when it is less than 1% in M8 the battery is completely drained or it goes to "normal" hybrid mode, as if it were not in M8, to preserve that minimum of 15%

@@JuanManuel-kj8rz The battery is never completely drained. It’s a 17.5 kWh battery. The top .2 kWh never gets used at all. The bottom (approximately) 2.45 kWh gets reserved for hybrid use. That’s always there.

Several people in the 4XE fans group on Facebook make those.

@@Wrangler4XEFans I have the Rubicon not the high output so they come on high output

@@patrickhealy4425 No, all 3 trim levels come black.

@@Wrangler4XEFans How did you get the emblem on on on the door where you charge it with a E yeah with the with the blue that’s how I wanna know how that came about I have a Wrangler for via E 2021 and it’s a Rubicon it did not come with that badging on the charging door like yours is blue

Also what are you referring to as Actual MPG? Is it miles driven divided by gallons of gasoline - ignoring electric energy in the calculation? If that is the case I get 66.7/2.321 = 28.7 MPG for the Blended Hybrid Mode case and 66.5/1.957 = 34.0 MPG for the standard Hybrid Mode. If it is based on gasoline only miles / gallons of gasoline I get 65.8/2.321=28.3 MPG for M8 and 45.6/1.957 = 34.0 MPG for standard Hybrid Mode. If I use the gasoline equivalent of the electric used (33.7 kWh/gallon) I get 28.5 MPG and 30.5 MPG respectively. In any case I agree with your conclusion that standard Hybrid Mode seems to be about 7% more efficient.

I’ve heard that you can.

@@Wrangler4XEFans I like to know for sure I don't want to destroy for travel use

@@jamieeisenhower1560 Personally, I would buy one made for it. It’s still going to be a slow charge even at 240 since it’s still going to be current limited.

@@Wrangler4XEFans I'm just wanting to enhance the one I got if it can be

Both manuals recommend 87 but say premium can be used for performance or towing. I’ve tried high octane on trips and haven’t seen any difference in mileage.

Thanks. Good to know. I haven’t taken delivery of my 4xe yet, but I was under the impression that premium was a must.

@@davesteele1042 A lot of people will say that since it has a turbo. A lot of dealers have told people that. A lot of service people will say that. I have a video series where I got the chance to have a conversation with Dan Fry from Jeep called “ask the expert”. That was one of the questions I asked and he confirmed that 87 is fine.

That would be about .001% of a percent of total weight.

Dang it, I didn’t break it down that way. Of course, gas varied by as much as .20 cents a gallon from place to place.

Ha, that’s a first. A lot of people say Letterman.

@@Wrangler4XEFans I could see that. Great video. I want a jeep 4xe. But wife and I cannot agree bc of no rear airbags for tye 2 young ones
