The figures quoted here are old, since EV sales have gotten a massive boost from spiking oil prices. The actual figures aren't out yet but anecdotal evidence at least in Australia suggests sales in March (across all brands, not just Tesla) doubled from February.

That said, for Tesla this is only a bandaid, since they have absolutely nothing in the consumer pipeline beyond the current increasingly uncompetitive offerings. Chinese brands like BYD, on the other hand, are laughing all the way to the bank.

It was always about first mover advantage and never about building a sustaining car manufacturer. It was about moving an industry.
DiscourseFan•1h ago
Obviously the oil spike, while not a relatively massive price hike historically, is clearly accelerating the pace of electrification, similarly to how COVID accelerated the use of zoom and other remote work platforms. But also similarly, it will probably be the case that gas is still used for some needs, just not nearly as many as today. People still do prefer their gas ranges, and its not as if natural gas is a great pollutant. But electricity is easier to manage than ever now, given battery capacity.
girvo•1h ago
Induction is better than gas in basically any way you can care to slice it, and natural gas in your home is actually quite bad for air quality.

Ekaros•1h ago
Could be. People are not very logical and schools don't teach math anymore.

It is somewhat complex subject. Taking in account actual use, cost of fuel and maintenance and then comparing it to purchase price and depreciation is bit of a work. And I don't think too many people do that when they should.

gambiting•29m ago
Well, it's being reported as a surge in interest, whether that is followed by increased sales or not will be seen in the next month or two once these cars are delivered. But anecdotally, second hand EVs which were flooding car lots everywhere have substantially thinned out. There are still some, but a lot less than a month ago.

https://www.regit.cars/car-news/uk-fuel-price-hike-sparks-36...

Also lol, you're funny implying that ICE cars aren't overpriced tablets on wheels either. It's all cars nowadays. And UK's cheapest car right now happens to be a pretty decent EV anyway, a Dacia Spring.

Didn't BYD just lay off 100k people?
defrost•30m ago
Just reported, yes, that's globally and throughout the past 12 months so that's a 10% work force reduction overall.

In the same period they're posting record sales, it's possible that's mostly a reduction in bleeding edge sales promotion staff, influencers, etc now they have better recognition.

Two press takes on likely the same company press release material.

* https://carnewschina.com/2026/03/31/byd-cuts-100000-jobs-wor...

That infomation lags current events, perhaps they are taking staff on now EV demand has spiked following oil shock.

ivewonyoung•25m ago

This says that sales are actually down. Where are you getting record sales from?

defrost•19m ago
> Where are you getting record sales from?

I posted two links that both say that, of course both appear to mirror the same primary source.

You'd have to drill into both cleantechnica and the BYD presser for the exact details and caveats that come with all such reporting.

  Revenue and deliveries reach new highs

  BYD reported 8039.6 billion yuan (1,123 billion USD) in revenue for 2025, alongside 4.60 million vehicle deliveries, according to the NBD. Overseas deliveries reached approximately 1.05 million units, according to Sina reporting, marking the first time the company surpassed the 1-million-unit mark in exports.

  BYD slashes 100,000 jobs yet posts record sales. Inside the cost cuts, profit squeeze, and why it’s still leading the global EV race.

bombcar•23m ago
Mostly unrelated (my surprise that BYD had nearly a million employees) - but a fun vibe coded game would be to give a company, maybe some stats about it, and then you try to guess the number of employees.
ivewonyoung•28m ago

This is all so frustrating. Tesla could have easily been an American auto maker generational success story. Instead they’re working hard to undermine their own success, turn their brand toxic, and even design vehicles that are unappealing to key purchasing demographics (Cybertruck).
throwaway290•1h ago
no worries, when things go hard and stock goes down they can count on Trump for a convenient war and oil crisis.
rvnx•1h ago
This war is going to push oil prices up, which means more EV sales. On top of that, make sure to sprinkle a bit of tariffs in order to block BYD.

Mhhh, makes sense.

freedomben•1h ago
The oil prices is a short term thing, and Trump is all about "Drill baby drill" so no, it doesn't make sense.

The tariffs though is a great point. Definitely a boon for Tesla from good old Papa Trump. It's grotesque.

What changed is he took the mask off. He was always the sleaze that he is today, but a lot of us were fooled into believing he wanted to do something good.
freedomben•1h ago
I don't agree after reading Walter Isaacson's excellent biography of Elon. It's deeply unfortunate that the book is already a few years old, I'd love and buy the hell out of a 2nd edition that is updated with the last few years.

Obviously it's always been latent in Elon, but he was a pretty bog standard lightly-if-apolitical silicon valley startup guy for most of his adult life. The free speech erosion under the Biden admin is what really started to "red pill" him and eventually led him off the cliff. It's a sad story really, but an important one because I think there are a lot of people in the same boat, and understandign them is important if we want to correct the trajectory of our country's ship. It's a damn hard problem though.

rjtavares•1h ago

stingraycharles•1h ago
I think the vast majority of people that operate at that level of success have a similar mask, but they’re more successful in managing it.

What caused Elon to lose his ability to manage it is subject for debate, I personally believe he discovered drugs in 2019 and the rest is history.

rvnx•59m ago
He brought good things due to high-conviction bold moves though, like democratizing EVs, reusable rockets, and most of all, actual internet in airplanes.
stingraycharles•56m ago
Yes, credit where credit is due, he achieved a lot, and was instrumental in both SpaceX and the whole EV transition.

He just took a wrong turn and seems hell bent on staying on it.

SirFatty•1h ago
What changed is that he doesn't have a publicist filtering his nonsense anymore.
masklinn•1h ago
2018 (tham luang cave rescue) is when the cracks really started showing up, so the trajectory was probably set a while earlier.

The tendency was probably always there given the serial lying about self driving started circa 2015, or the weird ego trip of ousting the founders and getting himself called co-founder, but if we’re looking for a point event the removal of his long time PA in 2014 still stands out to me.

jongjong•57m ago
What did he do specifically to crater his reputation?

Is it his politics? He seems to have reasonable beliefs there. It's not like he's been supporting Trump unconditionally. He doesn't always agree with Trump. Is it because of his stance in favor of free speech? How is that a bad thing? As someone who doesn't like any side of politics, I don't get it.

surgical_fire•8m ago
Dude did a Nazi salute and made a speech in support of the neonazi party in Gernany.

I think we got a few steps beyond "reasonable beliefs".

I mean, perhaps it is reasonable for you, but then we will find very little common ground.

No. For all practical purposes, Chinese cars are perfectly fine for most consumers. Since you cannot beat China on manufacturing costs, this war is already lost. Musk or no Musk.
adjejmxbdjdn•40m ago
There is no reason Chinese EVs couldn’t have been beaten on cost.

The labor/environmental costs of car manufacturing is relatively low and more than made up in the cost of shipping cars. One example of this was the number of foreign car manufacturers that were relocating manufacturing to the NAFTA region to serve the U.S. car market even before the tariff nonsense.

The area where China might have an edge is batteries cost. I’m not convinced that’s the case but even if we assume it is, it’s irrelevant because Chinese battery companies are largely not vertically integrated with the automakers and have been selling those batteries to non Chinese automakers at the same rates in an open market.

The reason Chinese EVs are cheaper is plain and simple competition. Some of those price advantages will disappear as Chinese companies need to start showing profits, but a lot of those won’t because they were the result of genuine innovation driven by the tremendously competitive market and the economies of scale that were rapidly created.

Keeping that in mind, while a lot of Tesla’s missed opportunities are self owns, the larger problem ultimately was the lack of govt support in developing a competitive ecosystem in the US.

whizzter•23m ago
Chineese phonemakers exist yet Apple pulls in a significant portion of profits due to their _halo_ allowing them to sell at a higher price point.

Tesla had that, all Musk had to do was refrain himself from waving his hand around in that certain fashion.

New registrations in Sweden for the past 3 years, Sweden alone would've probably absorbed about 14000 cars of that unsold stock.

  2023  20388  341835  0,0596428101276932  (5.96%)
  2024  21894  314485  0,0696185827622939  (6.96%)
  2025   7254  314426  0,0230706112089967  (2.31%)
  2026   2849   72525  0,0392830058600483  (3.93%)
(Sales in 2026 were low until March 2026, Musk probably gotta thank Trump for oil-prices jumping up enough to move the needle again)

The worst news for Tesla isn't the sales though, with "Texas-like" distances in Sweden (and Norway and Finland) there was a perception that only Tesla cars could properly handle the distances without getting too much battery angst.

When people started looking around they realized that the other carmakers were getting their shit together and could actually deliver cars that handled distances well enough.

amelius•13m ago
> Chineese phonemakers exist yet Apple pulls in a significant portion of profits due to their _halo_ allowing them to sell at a higher price point.

The difference is that most customers have the financial wiggle room to buy a more expensive phone. With cars this is an entirely different story because cars are the most expensive things people own (besides a house).

bulbar•13m ago
Buying a Tesla was already considered edgy in some demographics, but doing that famous fascist gesture because you feel powerful definitely crossed a line as far as Europeans are concerned.
tlogan•1h ago
I think Tesla as a company is doing the right moves. The management (excluding Elon) seems solid and smart.

The problem is that we often attach a company or a larger idea to a single person, even when it is much much bigger than that individual. People started boycotting Tesla because of Elon Musk, without considering that Tesla is actually thousands of engineers, workers, and managers. And majority of decisions are not done by Elons.

But people tend to think in terms of heroes and anti heroes. Cesar Chavez is another example of how this dynamic plays out.

Great things to have on balance sheets. With inflation their value can only go up. And as they are level 6 self-driving capable as is soon they can be sold for massively more money. Really they should stock pile hundreds of thousands more.

Their worth is tied to what people are prepared to pay for them. And right now most people aren’t prepared to pay for Teslas.
twic•40m ago
You're completely right. I've got an idea for an investment strategy. We start a company, and issue shares. We use the money to buy Teslas, and hold them as assets. As the value goes up, the value of the company will rise. Then we issue more shares, at a higher valuation, and use the money to buy more Teslas. Infinite money glitch. I call it a Drivable Asset Treasury company.

Tesla has an P/E Ratio of 332 (in comparison, Apple has 31.3) - the stock price is not based on measurable numbers so I don't think that the unsold EVs will have any consequences for the valuation.
