Nice. Those are small parts, though. The interesting part is the E-axle. BYD builds a unit with an integrated motor, differential, axle, and wheel hubs. That, plus an electronics box and battery, is the power train. This simplifies vehicles considerably. There are E-axle teardown videos. There's no big secret about how to do this. Copying this is hard for Detroit, because they have a huge investment in "engine plants…

You have some false beliefs about Detroit’s product lines. Fords mustang mach e is unrelated to the gas one. Totally different platform. It was designed from the ground up as an electric platform. The electric F-150 was a shrewd bet that didn’t pay off, but a pretty defensible decision to try to electrify the most popular vehicle in North America without changing the outside look too much. Under the sheet metal it do…

True, the Mach E mostly just shares the name. The E-Transit really is the same van with a different power train. It ought to be taking over fleet sales, but it only sells about 12K units/year, vs. 162K for the fuel powered version. The Ford electric F-150 was overdesigned and overpriced.

Comments on the Bolt indicate it's being killed due to "changes in the political environment."

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…

Vertical integration matters. If BYD controls much of the chain from the mine to the ship, they’re not paying everyone else’s margin along the way. That can translate into more car for the money.

I own a BYD Tang, so I’m biased, but the value for money has been hard to beat.

Scale probably helps too. When you sell millions of cars using many of the same parts, availability is better and parts are more likely to stay affordable than on low-volume models with lots of redesigns.

And also the simplicity of the products. You don't need to design a different engine for each car, you just vary the number of cells and change the motors. Your battery division can keep pumping out batteries, regardless of what models you make. If you design a new model, you can keep using the existing lines. It's perfect for mass production.

It was suspected in the past that Lumafield used AI to write the descriptions of previous scans. It is possible they are still doing so.

If it's AI then I'm surprised to see it make this mistake: > None of these components is particularly extraordinary in isolation

Why is that a mistake?

This is interesting. Wasn't the idea in Europe (and maybe elsewhere, too, no idea) that outsourcing components would lead to economies of scale? After all, a Mercedes or BMW or VW seat is still roughly a seat?

It's interesting to me that we seem to switch back and forth between the two models, each time saying the new approach is "better".

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…

>they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills

It's more complicated than this. Historically, Chinese manufacturing has been notorious for quietly undermining the quality of the product to improve their margins over time, in a way that the commissioning brand doesn't notice. If a Chinese manufacturer quotes you a price too good to be true, they're probably quoting you at-cost and will build in their margin later, once the orders start flowing in.

VW, Mercedes and BMW also squeeze their suppliers very hard, and they operate with razor thin margins. So I agree and wouldn't say that doing everything in house is always going to be the cheaper way

>The control arms, subframes, etc all look good and don't fit the 'chinese car bad' narrative you always hear. While I think the "chinese quality bad" narrative still applies to many Chinese brands, this isn't as universal as it was in the past. I think my eyes were first opened when I bought myself a Huawei phone(before the Google ban). My first few smartphones had been Samsung, I've always felt the term "planned ob…

Oh man I miss my Huawei phones. I had an Oppo at one stage too.

As an aside the best phone I ever had was a HTC One X, another brand that I sorely miss.

I agree with the quality of some of the stuff coming out of China but when it comes to poisons and risking the lives of citizens, I have some bad news for you. That is how they undercut so heavily by foregoing those standards.

In China, they hang those that are responsible. In US, they get slap on their hand.

Or they get cabinet positions.
