They’re already heavily taxed. But why vilified?

There's a huge overlap between people who seek out such experiences and those who drive recklessly and modify their exhausts.

Or maybe you're not particularly interested in cars or the people who are interested in cars and you can't tell the difference / assume all of "those" people are the same,

I think many of people here live in US and assume that it everywhere things look similar. in my European country electric infrastructure is not ready for electric cars and with current energy prices this makes no financial sense. I own plug in hybrid and I live in apartment meaning I have no possibility to charge at home. near me (about 10 min of walking there is public single phase allow charger with 2 plugs machine…

If I may disagree: I live in a flat with a fully electric vehicle. It's just a matter of planning around charging a bit. Once you think ahead (and it's not dramatic), you don't notice anymore. I find plug in hybrids make no sense: electrification is the future.

Those of us living in the present prefer to be more flexible and have the best of both worlds (electric commute, ICE for long trips)

Presumably as Porsche is not about efficient transportation; it is about emotion, driving as an experience, making a statement, etc. Chances are there will be - or, at least, Porsche appears to bet there will be - a sufficient number of well-heeled enthusiasts who prefer the sound, smell and vibration of an ICE to the quiet performance of an electric motor. I am really curious to see how this pans out in a generation…

If you're into that exotic hobby long after ICE cars are obsolete, you'll need to purchase synthetic fuel for it or purchase the equivalent amount of CO2 direct air capture. Sounds okay to me.

Really, just a bit of “planning around charging”? The less predictable your life is the less this is an option. The most extreme example of this is Hertz having to walk away from billions invested in 100,000 Teslas. Short term renters simply don’t tolerate the uncertainties that EVs bring.

> Why waste R&D on a dead end? "There were an estimated 20 million horses in March 1915 in the United States" [1]. In 2023? Almost 7 million. Internal combustion engines will be around for a long time, in part because they're beautiful. [1] https://en.wikipedia.org/wiki/Horses_in_the_United_States#St... [2] https://www.ppfas.com/pdf-docs/b-finance/cigar-butt.pdf

Were horses ever actively restricted by governments around the world or did we move away from them because better solutions were available?

They were causing environmental problems, cities were clogged up with horse shit. I don't know whether that influenced the transition though.

Which ICE performance car? I went from an SRT8 back in 2012 to a Tesla Model 3 performance + mods and now most recently went back to ICE via an AMG GT63. I can confidently say that the GT63 is leagues more fun than the Tesla ever was. Sure the Tesla was quick off the line, but outside of that it felt sterile and the ride was quite uninspired.

Model 3's didn't exist in 2012. Did you mean something else? I've driven an M3P for 5 years, and I wouldn't call it sterile. I haven't been cross shopping it with vehicles that cost 3x as much and get only 15% of the mileage, so maybe I'm missing something? But weighing 10% more and taking 20% longer to reach 60 doesn't seem particularly compelling.

If it's the only car you've driven for five years of course it doesn't feel sterile, it's a wonderful car, and nothing against it, but it is not a fun car / "enthusiast" car insofar as enthusiast refers to the thin slice of all automotive enthusiasts that are primarily interested in handling that is dynamic and communicative

Honestly, i can’t get my head around how many folks actually think that it is an either or situation. There’s zero chance we will be able to electrify all personal mobility let alone the elephants in the room being construction equipment, planes of all sorts and above all marine vessels that ship our goods globally. EVs are well suited for a couple use cases but far from a monolithic solution. It is beyond me how a g…

I wonder what three degrees of warming will be like.

Lol, I really want to see a 150-year old EURO6 200kw diesel engine coupled with a 150-year old 9-speed automatic dual-clutch allowing me to drive on the 150-year old roads for 4 liters per 100 km at German highway speeds. BTW, electric cars are older technology than ICE cars.

The main innovation in modern electric cars isn't just about swapping fuel with electricity, but eliminating all junk in between that wasted power only to overcome ICE inherent flaws. More simple electronics aside, clutch, gearbox, then driveshaft are all gone, and they contributed to a huge waste of power, which burned a lot of fuel for nothing. This is so bad that where possible and economically feasible (trains an…

> clutch, gearbox, then driveshaft are all gone, and they contributed to a huge waste of power which burned a lot of fuel for nothing.

Practically, they are replaced by even more "junk" in the form of literal tons of batteries weighing more than the part they replaced, the electric motor having to expend more energy to carry this extra weight around..

> what makes it a better option also for cars required modern development, especially in batteries and rare earth magnets which would have been unthinkable only a few decades ago.

Is it, though? I'd like hard facts on that. From what I can find, battery chemistry hasn't seen any breakthrough, only their cost has steadily decreased, in large parts thanks to economies of scale and an oversight for externalities mostly in the extraction and refining supply chain. Similarly, high efficiency electric motors have been a solved problem for a century. I think the whole charger infrastructure and finally getting to the end of the chicken and egg conundrum has more to do with EVs becoming a thing than some new tech having enabled it.

I assume you live in the US.

Because in almost every other country there is a real lack of decent charging infrastructure.

Especially outside of densely populated areas.
