While at the Jeep Academy I went to last week, the corporate reps were talking to me about my Gladiator (one of them claimed Snazberry is his favorite color - that's how we got to talking) and asked if I was interested in the EV coming out next year. I pretty much told them NO because of how much driving I do for work - up to 300 miles a day. Plus, if someone goes out in the mountains or another area that is "in the middle of nowhere" for a day or so to hit some trails, where are they going to charge up at? They both looked at each other, then at me, and said yeah, I wouldn't recommend you get one.
That's why when i get into EV talk - I try to preface it all with
an EV is ideal for some, a disaster for others;
a PHEV is ideal for some, not so much for others (although you simply put gas in it and it's a hybrid, no worry about charging stations - like our trip to FL and back to IA)
for others, a plan hybrid is great, but others aren't interested,
there's also the eTorque and other mild hybrids, where a diesel is actually pretty suitable
and for some, gas or diesel is perfect, don't even bother thinking about any of the above (except maybe the eTorque)

There's no one size fits all since the PHEV, EV and Hybrids have come out.

For my wife - a PHEV is actually perfect, an excellent fit. And it works for longer trips just like any other Jeep might - although not as high a mpg factor as a plain 2.0 or 3.6 might be in the same brick or toaster.

So I don't know why the big fuss sometimes - as long as there's still ICE powered vehicles, or at least mild hybrids around, we'll all be fine.

Again - if the 4xe Gladiator can haul the same payload, tow the same trailer weight and do all of the same things the current versions can do - I'll be bugging the heck out of my dealer to let me look at one (buy - that's a matter of money, but like a pretty girl to a married guy - you can still look and admire - just not too closely.......)

EVs, PHEVs, and HEVs all are heavier than their closest counterparts. It takes MORE energy to move MORE mass. Basically we are increasing our energy needs no matter how we get said energy. You might as well draw a straight line from energy required to pollution no matter what source you’re getting that energy from.
You are missing one critical component here: efficiency. If your weight is 50% more but efficiency is 4x (ICE have around 20% efficiency, EVs have around 80% efficiency) then the EV consumes only 37.5% of the energy of the lighter but equivalent ICE vehicle.

The engine alone has a thermal efficiency of about 50% but in a street legal car, it's down to an average of 30%
An EV is 60% efficient as far as "from the grid to powering the vehicle."

So yeah, the EV is twice as efficient in that respect.

Math checks out, I go 21 miles on half a gallon of gas worth of electricity, compared to a bit over a full gallon to do the same on gas, so at least twice as efficient probably a just a bit more.

Can you please explain your math? You used 1/2 gallon of gas and went 21 miles with the assistance of another (battery/electric) source of energy? so you used 1/2 gallon of gas PLUS how much electricity? I’m not trying to be difficult just trying to understand what you are explaining.

He's saying the amount of electricity used to go 21 miles was the equivalent cost of a half gallon of gas.

He's saying in the ENERGY EQUIVALENT to 1/2 gallon of gas worth of electricity, he went 21 miles. But on gasoline, it took a gallon to go the 21 miles.
You figure the energy equivalent to gasoline in electrical energy.

Not going to try to explain the math - that dude knows what he's talking about.

1/2 a gallon of gas worth of electricity which is 16.5kwh of electricity. So I did 21 miles on what would be the energy equivalent of 1/2 a gallon of gas if it was utilized at 100% efficiency. Meanwhile on gas engine I get 18-19 mpg at best so it's a little less than half as efficient as the electric motors are at utilizing energy.

Edit: I'm playing a little loose as the 4xe really only uses 14kwh of its 17kwh battery but there is some Regen in there too so I just made the math easier by saying half a gallon (16.5kwh) instead of .4ish

Bill this is what most sane people would say.

We are fortunate to have four different vehicles, one of which is a Tesla. I bought it somewhat as an experiment to see how usable it is and I’ve been surprised at how versatile it is. We’ve taken several multi hundred mile trips without issue. BUT I will say that it can’t do everything and that’s why we have other vehicles.

I read that the revised CAFE standards just came out that will require OEM’s to achieve 50.4 mpg by 2030 or so..and that’s insane so some sort of electrification is coming BUT I hope that ICE vehicles will still be available for the significant amount of people that will still need them.

I watched an interesting video yesterday that said Tim Kiskisis was fired/ resigned after getting into a beef with Tovaris over his refusing to buy energy credits from Tesla which would allow Dodge to keep building their hemi monsters…

I really appreciate you breaking that down for me. As we move solidly into the hybrid only future, I want to compare apples to apples and not have differing math and expectations.

random question…Does diesel also equate to 16.5kwh?

Diesel is about 37 kwh per gallon, this is actually part of why diesels get more mpg (also diesels are typically about 5% more efficient than gas)

like bleda2002 said - they retain the heat and use it more for power than gas engines.
Gasoline is figured at xxx BTU per gallon - you likely know that's heat units as a simplistic answer. The more of that heat energy that can be used and not lost out the radiator and exhaust, the more efficient it is. You can figure the BTUs of energy per kWh of electrical power as well. Gas is about 114,500 BTU summer blend, depending on the blend, ethanol and so on, I think the EPA uses 115,000.
Winter blend is around 112,000-113,000 I think.

Diesel is slightly higher, I believe closer to 130,000, plus there's less heat loss in a diesel - more of those BTUs are used.

Diesels are excellent engines for lowering heat rejection - meaning they retain more heat and get more BTUs out of the fuel for propelling the vehicle.
Diesel engine heat rejection - look those up if you want some really deep reading! Get your glasses on and get a couple beers by you and dig in.

Gas engines can be made to handle more heat - less heat rejection means more of that energy propels the car, but it's really limited.
I suspect this is one reason FCA has made the 3.6 run in the higher end of the old normal. Still very very normal, nothing to freak out about, but the higher temperature really make some people cringe and gripe about the engine running TOO hot. It's not. It's a new normal.

There's a ton of information out there on how to figure all of it, but that's more time than I've got and I'm trying to work myself out of these forums because people hate facts and math and scientific studies and hate someone actually knowing stuff LOL
Just not worth the hassle.

So this past week, popping in for the easy stuff........... toss in my response and leave.

You've asked valid questions, wanting to know. That's worth getting some decent answers.

"Bill" and "sane" in the same sentence. Thanks LOL.
With the severe ADHD and hyperactivity, flitting around doing things at 150 miles/hour, sane is not what most would say..........
But all messing around aside, I'm just against those who have no real experience, jump on the "IHATEEVS.COM" sites and spew the hate. As with many things, it's not black, it's not white, the truth is somewhere in the middle. We are in the early stages of this revolution. There will be alternatives coming out as the auto companies beef up their R&D and get out of their "this is the way we've always done it" bit.
I have to give Toyota much credit - like me, going ahead with a PHEV in part out of curiosity, Toyota bought Teslas, and their engineers dismantled them to figure out "how in the !@#$ did they do that"??
Other companies sat back on their laurels and are floundering - Toyota spent time and money to learn.

I'll never - ever - have a hybrid or electric car/truck/Jeep. Thank God I have a 2020 and I intend to keep it.
