“Battery EV” vs “Hydrogen Fuel cell EV”
SiliconWizard:
We may or may not agree on the minute details, but one thing I'm almost sure of is that EVs are not going to be as scalable a solution as ICEVs anytime soon. And I do not think this is the intent either, as it looks like general politics tend to get us towards a world with a lot LESS private transportation anyway. Just saying. So if someone is ever dreaming, it's probably mainly about that point: EVs replacing ICEVs exactly, by similar numbers and use cases. Yeah right. :)

It's a Volvo 740, 2.3L SOHC turbocharged 4 cylinder gasoline engine. It's over 30 years old so not really "modern" I guess but it's not ancient either. The one I had with 330k on it was another 740 with the same engine.
We also have a slightly more modern 2002 Toyota Prius, it only has 140k on it but shows no signs of engine wear. I don't know if they're still using those but Microsoft had a whole fleet of Prius shuttles back when I last worked there, they had some with over 300k on them.

OMG, stop, just stop! I'm sorry but you are so full of shit, every one of these threads you come in and start making these absolutely absurd arguments, completely un-encumbered by reality. Most of what you keep saying is simply not true, you're making mountains out of problems that were solved years ago, claiming things can't be done that are already being done by millions of people, inventing new problems that never existed and it's just getting ridiculous. You don't like EVs, we get it, that has been made abundantly clear, so don't buy one and that problem is solved. Meanwhile the rest of the world is getting on with things, and large numbers of people are finding them perfectly suitable, enough so that some of the best selling cars in the world are EVs. Yet you continue to argue endlessly from some alternate reality where none of this has happened yet, continuously inventing problems that don't exist or making up data that is wildly exaggerated. It's just ridiculous.

No, you just keep living the pipe dream. In an older thread I brought up the fact that putting an extension cord over the side walk is not a good idea because of liability issues due to tripping danger and likely to be banned. I was the forum's idiot for even bringing it up. Fast forward to today: in the city I live in you get a fine of 259 euro if you charge your EV using an extension cord over the sidewalk. The reason behind it --drum roll-- : liability due to tripping danger.
Sure it is easy to solve all the problems in the world sitting from an comfy armchair but the reality is much thougher than you like to think.

There is no requirement to charge outside your home. Most cars will soon deliver 500 km or more this is more then most people drive in a week. They’ll charge at commercial
fast chargers as and when they require. House charger is a temporary thing , BEV batteries will soon be bigger then the capacity of a house feed to charge then in a reasonable time.

That makes no sense at all. House charging is the single biggest benefit of an EV, you just plug it in at home and trickle charge overnight, you never have to go looking for fuel, it's just full every morning. Charging stations are for people who cannot charge at home but still want an EV, and to alleviate range anxiety and allow for the occasional longer trip. Even Tesla has stated that their intent is for most charging to occur at home, that's the whole plan. I get that not everyone can charge at home, my dad was in that category and he made use of Superchargers and destination charging to charge his Tesla but everyone I currently know who has one plugs it in at home. Home charging is an absolutely huge feature, it's fantastic, it's something that every EV owner I know loves about their car.
Seriously, I love my old gas car, but if it were possible for me to trickle fuel into it overnight in my driveway or garage and have a full tank every time I go out somewhere, I would gladly give up the ability to fill up quickly at a gas station. I absolutely hate having to go get gas, it's always some inopportune time when I realize I need it, seems like it's always either cold and windy or roasting hot out, it's always out of my way, I hate the smell of gas stations, it's probably my least favorite aspect of car ownership.

Today is common to have a 1.0 turbo with an even higher power, in the car this size
Plus oil change interval is set mostly for 40,000km (25,000 miles) to lower maintenance, it is proven to damage engine, but fleet customers want it as they don't keep cars that long and for example, in Europe, it is a big part of the market, a big portion of people here have the car as an employment benefit
