This is true for me, I have an S.
I’ll also never buy another tesla again but I’ll drive this until the wheels fall off. It’s 5 years old now.
There is no Moore's law of batteries. BEVs are always going to be fairly expensive compared to other types of cars.
Not to mention BEVs are old technology. They literally pre-date internal combustion cars.
@Hypx There's no Moore's Law for batteries because they're a different technology. Transistors today are still fundamentally the same as the first transistor, made in 1947. Batteries, on the other hand, are constantly evolving. The first LiPo battery wasn't invented until 1997, and there are multiple new battery technologies currently being studied, like solid state batteries.
Are you seriously joking? A transistor today is much smaller and faster than what existed in 1947. That is what is driving Moore's law.
Batteries evolve only very slowly, and run into hard physical limits at every step. As a result, BEVs are very expensive and have major downsides like weight, long recharge times, etc.
@Hypx Yes transistors are smaller and faster, that's the literal definition of Moore's Law. But a transistor today is a smaller, faster version of the exact same technology as the first transistor, applying a small signal to pass current between doped semiconductor junctions, the only major difference being changing the semiconductor from germanium to silicon.
Batteries, however, are fundamentally different from when they were first invented. Yes, it's still storing electrical energy as chemical energy, but the chemistry has changed so much since the first batteries. The word "polymer" wouldn't even exist for another 20 odd years. And new technology is constantly being discovered, such as solid state batteries or supercapacitors.
And if you want to talk about physical limits, Moore's Law is essentially dead. We're nearing a point where you'd have to split atoms to make a smaller transistor. Batteries are limited by their chemical makeup, transistors are limited by the laws of physics.
That’s ridiculous. You basically admitted that we switched from germanium to silicon, but that this apparently doesn’t count as a difference.
Not to mention that this is massively off-topic. The point is that batteries do not improve as fast as transistors did in the 1990s. Hence why an analogy is wrong.
And if you are aware that Moore’s law is (more or less) dead today, then you should understand the problem that batteries are facing. They too are hitting hard physical limits. You talk of solid state batteries but they are nowhere to be found right now. Clearly, this is a hard problem and future batteries will not magically be far superior.
But ultimately, there are other green ideas not called the BEV. Including other types of EVs. This is why I try to make it clear that I am talking about BEVs specific. Not EVs in general. Once other people become aware of this fact, it will become much clearer that the BEV is a fad. It is an expensive and very limited idea. It is arguably an idea stuck in the mid-2000s, and its advocates have simply failed to move on.
I would say that's pretty unlikely there will be a 10x improvement in battery chemistry. At some point, we will have to deal with the fundamental limitations of the technology. That will likely imply a different kind of EV. Other conversations in this thread have brought up the FCEV, which is honestly the mostly likely guess for what comes after the BEV. In other words, the solution is to move beyond batteries, not pretend we can just improve batteries ad absurdum.
Also, this is basically the point of the book The Innovator's Dilemma. Technology does not improve linearly exclusively. At some point, major shifts in the market will have to happen. If you think about this problem honestly, you probably have to conclude that the limitations of the BEV must be solved by a big leap forward, not incremental improvements in batteries. And if you can reach that conclusion, then you must realize that the BEV has to be a transitional technology. Perhaps, even a fad.
If we're talking approaching fundamental limits, Hydrogen fuel cell is not a great comparison. A high pressure tank can only get so light, even with linerless ultra high strength carbon fiber pressure vessels, the mass of the vessel is maybe 6-10x the mass of the hydrogen it carries. To increase specific energy there you need to go to cryogenics which is a whole technology leap and has its own set of challenges.
Battery tech has been improving more than you have seen, clearly. Since '08, lithium batteries have increased energy density by 8x (https://www.energy.gov/eere/vehicles/articles/fotw-1234-april-18-2022-volumetric-energy-density-lithium-ion-batteries). The best LiPo batteries are around 0.9MJ/kg right now, but there's no fundamental reason a battery couldn't achieve 9MJ/kg. Lithium-air batteries could theoretically achieve way higher energy density than that even (https://en.m.wikipedia.org/wiki/Lithium%E2%80%93air_battery), and have already been demonstrated in a lab to achieve more than 5x what current commercial automotive batteries are doing.
Except those fundamentally limits are far higher. The fact is that hydrogen stores energy at 120 MJ/kg. Even at 5% weight efficiency, that's 6 MJ/kg. Or 1,666 Wh/kg. Far beyond any battery.
Your link is seriously lying. 8x is the gap between lead-acid and li-ion batteries. The claims are simply impossible. The author must be unknowingly comparing lead-acid battery powered cars to li-ion battery powered cars. I cannot see any other way his claim is true.
A lithium-air battery is literally a fuel cell. In fact, what did you think hydrogen fuel cells were this entire time?
Are you talking about FCEVs? You can also include directly electrified vehicles, but that is mostly mass transit.
And yes, electrification as a whole will succeed. But BEVs probably are not. I call them fads because they are just toys for the rich and they are unlikely to be affordable for most people.
There's plenty of BEVs that are competitively priced to any other new car: https://www.caranddriver.com/features/g32463239/new-ev-models-us/
They might not be the car you choose to take on a road trip, but most days, I only need to drive less than 20 miles anyway.

So you just have a hydrogen full cell manufacturer's name as your username and post extensively in https://kbin.social/m/Hydrogen for fun or do you think you maybe have a conflict of interest here and are being disingenuous?
Because I want to tell the truth, not swallow marketing propaganda from Tesla. In reality, BEVs are a fad and no amount of wishful thinking will change that.
The name is a coincidence. I've used this name for a long time (from elsewhere to be clear).
Overall, not surprised.
Couple of points I noticed were missing:
These are their most affordable models, so I’m reading this article in terms of the Model X & Model S, and not every owner. The data did say that the Model 3 was predominantly male-owned, and I expected nothing less from a car marketed as a sports car.
A state that was once identified as “Camry California”, the Model Y exceeding Camry sales in the state is a big enough deal to include that data to qualify an article that describes all Tesla owners.
“Six figures.”
Can we retire this phrase? A lot of these people are earning multi-hundred-thousand dollar salaries. And many of them live in expensive areas where $100k is not some magic number that means you’re rich.
It’s just such a cringey phrase. Not specific enough to be useful, and loaded with economic misconceptions.
The use of “six figures” as a measure of affluence goes back to at least the 60’s… if we use 1970 as a baseline, a salary of $100,000 then is $800,000 today, accounting for inflation.
Inflation isn’t the whole picture , but helps to demonstrate how dated the phrase is.
I just want an EV that is:
-Reasonably priced.
-User repairable/modifiable.
-No stupid luxury gimmicks (fake “self driving” or “self parking”, 360° cameras for outside view, electronic locks that will most likely fail in a couple years, etc…)
-NO FUCKING SUBSCRIPTION SERVICES like those stupid heated seats!!
-User repairable/modifiable.
It’ll have to run on a couple of AAA-batteries then.
If I were rich I would like an EV based on the fact that I hate gasoline.
But I dont trust my road safety on a billionaire crybaby who gets triggered by the word “cisgender”
Lots of better options out now. And in 5 years, Tesla may be the worst of them, given how bad their quality control is.
I just wish it wasn’t their charging network that manufacturers were moving to, but I have to admit that it is better than the alternatives. And we do need a single standard like gas.
