PHEV vs full EV, which is right for you?

[ZeeOSix]

Nothing is exact without perfect knowledge.
50 + 50 = 100, right? Not always...

If you add 50 mL of water to 50 mL of water you get 100 mL of water. Similarly, if you add 50 mL of ethanol (alcohol) to 50 mL of ethanol you get 100 mL of ethanol. But, if you mix 50 mL of water and 50 mL of ethanol you get approximately 96 mL of liquid, not 100 mL.

But science tells you exactly why you get 96 mL of liquid, and not 100 mL.

Exactly.

50 + 50 = 100 always. If you add ml it becomes something different. As you show.

But it changes. We are taught that science is exact but as time goes on we find out that it changes as it understands things better. I don’t call that exact.

Pluto was a planet. I learned that in grade school. Then suddenly it’s not.

That's not science, that's politics, just like how do you define whether it is a language or a dialect.

I'm sorry, but that's just not true. Please be careful with absolutes,
50 + 50 = 84 in base 12.

My point is, without context, how do you know?

The facts don’t change, but the models explaining the mechanism behind the facts, and how we should react to the facts and models, do change. As more facts come into existence (or are realized, or measured, or otherwise quantified).

Pluto’s classification change did not change anything about Pluto, nor what it is or isn’t doing. It will be the same as it ever was.

You were counting ml in base 10. 50 does not equal 50 ml, that's why it can come out to 96 ml. 50 is a number, 50 ml is a number times the volume unit. I don't see why you want to start with what about base 12, that isn't the base you were talking about in the example. Your example doesn't show 50 + 50 is not = 100. "We need to be careful."

You wrote "50 + 50 = 100 always." in post #43. That's what I was referring to. Apologies if that is not what you meant.

Guess not everyone understands the science (not voodoo) behind why mixing 50 mL of water and 50 mL of ethanol results in approximately 96 mL of liquid, not 100 mL. That was the main point of his example.

This gentleman owned a Jaguar iPace (pure EV) for about a year (and he bought that after also spending a great deal of seat time in a Model 3, he doesn't say why he went with the iPace instead in this video) and has decided to swap it out for a BMW X5 45e, which BMW has lent him on a long term loan for the testing. He considered the Land Rover PHEV, which he's also tested, but the electric range is less than half of the X5, and it's more expensive.

What he found with the full EV is what many people are afraid will happen, particularly with the less mature non-tesla charging network. You find yourself concerned about where you are going to charge on longer trips and then you just take the gas vehicle instead because you don't want the hassle. Then the EV ends up becoming a local errand tool, at which point, why spend that massive amount of money?

This is his initial review, with about 1,600 miles behind the wheel:


This is his subsequent review with just under 10,000 miles behind the wheel:


Second video he shows the HUD and more stuff he's learned about the vehicle over his ownership. Both are well worth the watch.

Its a concern, for sure but it really depends where you live and how many charging stations there are. Also, theyre adding more charging stations all the time, so Im not sure how concerned Id really be about it.
For me personally, I drive 100 miles a day and could charge my car in the garage every night, so its not a huge concern for me. If I go on a long road trip where charging stations are questionable, Id just rent a PHEV or straight gas car.
IMO, reviews like this are just naysayers who fear change.

Prius Prime, lmao? That really amps up that candyass vehicle doesn't it? Every Prius I've seen deserves a pipe bomb...

What the **** is wrong with you

No more than *** is wrong with the Prius design, lmao. Butt ugly POS litter the roadways and are a joke to be stuck behind in areas where passing is impossible.

No, I apologize more for not recognizing immediately there are other numbering systems that exist, and it's all my error for assuming base 10 was being used in the example of alcohol mixing with water. Sorry sorry, you are so correct.

As for plug ins I see Bentley has a doozie, saw it on the recent episode of Motorweek, and how about the VW ID. 4 full EV, or whatever it is, tested out nice on the same episode.

Every powertrain has its pro and con, but force/nudge people in every way to pick a specific one create a problem.
I will choose PHEV just because I like Hybrid technology. Watching 919 hybrid/R18 hybrid/Ts050 singing 24hr in Le mans is a joy. Watching FE race cars squeezing each other in street circuit is painful.

I was thinking about choosing Emerald Green.

For anyone planning on owning a car past the warranty period I would not advise a PHEV. The two combined systems can create some eye watering repair bills. For me personally it’s either ICE or BEV, pick one or the other.

Yes, I'm thinking extended warranty might be a good idea.

What PHEV do you own, the Q5?

I don’t own one. I’m a Audi HVE so I see what goes wrong with the different models and while the PHEV is reliable I would not want one. I‘m waiting a couple more years before I buy a BEV which will be either a BMW or Audi.

A plug in Prius would be cheaper than a Hyundai with bad engine design or a Nissan Leaf with bad battery design. It is all about how it is build and how much you pay for it.
