IBM no longer has fabs (spun off as Globalfoundries and later sold), and no longer manufactures PCs (sold to Lenovo?), but it does make mainframes I guess?

I thought GlobalFoundries was AMD's fab division spun off.

Yes, more specifically IBM -> AMD -> spin off.

I'm having a Seal delivered next week, really looking forward to it. My friend went from a M3 to a Seal. She does a lot of miles. She says they trade blows, there's things that felt better in the Tesla and things she prefers in the BYD.

I've got a friend whos a master tech/trainer with our state automotive body, and is HV certified etc for dealing with these cars. He's currently got a BYD Shark strewn across his workshop for an autopsy. I have to say I'm super impressed with how heavy duty everything is. The control arms, subframes, etc all look good and don't fit the 'chinese car bad' narrative you always hear. The powertrain components all look to…

In the last few years Chinese manufacturing has reached a very high-level. The reason most people still believe that Chinese-made stuff is poor quality is because they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills. While I reckon some other countries still have specialist manufacturing in key areas that surpasses China, most “common” parts can be…

>The reason most people still believe that Chinese-made stuff is poor quality is

I think most people just buy trash at WalMart and Amazon and it's 99% Chinese disposable junk. That doesn't mean that China is incapable of producing high quality goods, but just that the average interaction that people have with Chinese goods are low quality.

It's the manufacturing equivalent of "How could the government be efficient? Haven't you ever been to the DMV?" (set aside that fact that many DMVs seem to be quite efficient these days)

EU has ASML, Airbus and their suppliers left.

the key component of ASML is invented and manufactured by the US, that is how the US can force ASML not to export its EUV machine to China. it is an American tech. Airbus is not the result of high tech manufacturing, it is the result of setting up regulations to stop others to join the competition. The entire EU is not capable of building any 5th gen fighter jet on its own, that is the best proof that its aerospace i…

I LOL'ed.

Saab is, but there has been no need to develop 5th gen fighters if there are reliable international partners that can provide them. Recent development made it clear the US is no longer a reliable partner and the European aerospace industry is working on reducing the dependence on US equipment.

Considering decent portions of the F35 are built by BAE, Leonardo, Rolls-Royce and Martin-Baker - all of which are working on a 6th generation fighter which is due to be flight tested next year - this doesn't really ring true.

>This simplifies vehicles considerably. On the contrary, this much integration makes repairs nearly impossible, meaning you might have to swap the whole unit(for a lot of $$$) when something small inside it inevitably breaks. Check out the articles published by EVclinic that cover such cases. Aftermarket EV repairs are already big business due to how difficult and expensive the OEMs make it.

I don't have so much knowledge about EV repairs, but I got burnt by this on ICE cars already - had a car fail a regular fitness test on suspension bushes, they weren't replaceable without replacing the whole arm(s). What should've been a $40 part was being quoted as more than the cars value. (I'm not sure if there was a way around this, there may well have been but I had other things going on and sold for scrap)

That particular example is a labor arbitrage issue - it's a better value to have a $500 assembly with $250 labor than a $50 part with $600 labor. If you have the know-how, BYO labor is the magical way to save on this sort of thing.

The worst practices with cars is when they make it too tight or engineered to work on. Ford was kind of notorious for this - some dealers would do cab lifts for routine-ish work to save labor hours. I had a 90s Cadillac that required un-mounting and tipping the engine to change the rear spark plugs, unless you bought a really expensive tool.

Cars only show if they're well made after like a decade? These are not washing machines or something. Sadly that's also why it's hard to buy a new car, you only know what's a quality car years down the line. First impression matters though.

The point is that you can't tell anymore just by looking underneath and counting the wtfs. I have a friend who's a big Honda fan, amateur racer, a true "petrolhead" but with an intact brain. Runs his own shop. Naturally there was a barrage of jokes when I rolled up in my new Chinese EV, but then we put it up on a lift and there wasn't really much to joke about. The platform looks boring and mature. Things are where y…

From what I've seen of youtube teardowns by mechanics, Chinese cars often have the air of modernity and future tech about them, but under the hood, they like to use technical solutions that were abandoned by European manufacturers a decade ago or more, leading to the cars not being competitive in driving dynamics to what you would get from an euro manufacturer for perhaps slightly more money.

Be thankful you didn't buy Beko. I had a horrible uphill battle trying to get them to honour a 2 year warranty in Ireland after about a years usage. After they finally engaged with the warranty, they had someone come out to 'fix' it once every couple weeks until I gave up and just bought a different brand washer/dryer. I'm now sworn off Beko, and will happily tell everyone I can about my terrible service :)

That's also a bit 'you get what you pay for'? Especially with large electronics/cars typically it pays off to go for the more expensive ones. Miele here as well and well past a decade And there are still parts too

Not anymore. I bought a brand-spanking new high-end Electrolux dishwasher and discovered it had a flimsier construction than the 20 year old one my mom has at home, that was an absolute bargain bin purchase.

Imagine glazing the country where a dozen companies were caught mixing melamine into baby formula, hospitalizing 50,000 and killing 6. This happened in 2008 by the way. https://en.wikipedia.org/wiki/2008_Chinese_milk_scandal

Wow you're literally seething haha. Kidney stones flaring up again?

Don't forget to put flowers on the tiny graves.

I have a Chinese EV too, an MG4 built by SAIC. It’s a really cheap car, significantly cheaper than its non-Chinese counterparts like the VW ID.3 or (roughly) a Hyundai Kona. The factory rust protection was maybe a bit on the lighter side, but everything else on it looks completely normal. The drivetrain is simple (no heat exchange mechanism between battery coolant and motor coolant, a slightly whiny motor), but also…

> VW ID.3 VW ID.3 is designed by a Chinese team in China, built in Shanghai backed entirely by the Chinese ecosystem. You need to be totally blind to consider vw being able to design & produce such a car on its own. let's be straight - the software in the car is not something Germany can build on its own. That 20 years gap won't be filled overnight.

This is false, the ID.3 was designed primarily in Germany but they sell a model customised to the Chinese market. They're two different cars from different production facilities.

All the control modules for the German model at least are manufactured by Bosch and Valeo in France and Germany - where the software is also produced.

As an aside, Bosch produces control modules and the underlying software for just about every western car manufacturer. 80%+ cars sold worldwide use their traction control system for example so I'm not sure where this so-called gap is.
