This was stated about the key: "Folded into the base is a mechanical backup key, a flat metal blade in a hinged housing." I own a BYD: this is not true. The key is not hinged; rather, the entire mechanical key pulls out when a small clip is unlatched near the top of the assembly (you can see it in the CT). I assume the circular hinge-looking mechanism in the CT is just a by product of the plastic/metal weld process.…

I wasn’t surprised by the backup key, but rather by how empty it was. I really wish key fobs were smaller. They are quite bulky in a pocket and bigger than all my actual keys combined.

If you own a 3D printer, there are oftentimes STLs people publish online to shrink the size of the fob.

Made my keys much less bulky

FWIW, this has been my experience since 2003 when I had to get suspension work done. Doesn’t matter if it’s a BMW or Honda, dealership or indie repair shop, the story I have heard consistently is that the bushing is part of the arm for structural integrity, stability, . Bushings typically fail faster than the arm does, and this repair is expensive ($1000+ for performance cars, not that much cheaper for Civics). The “…

> repair is expensive ($1000+ for performance cars, not that much cheaper for Civics) I can almost guarantee the lion's share of this is shop labor, not parts, and pressing a bushing out and back in would be more expensive after accounting for that labor than just swapping the suspension arms. This is often the piece that gets missed in these discussions of "why am I replacing this huge assembly for a tiny part", if…

I’ve moved in to doing my own plumbing, electric, HVAC. Tend to keep new enough cars that they don’t need much, knock on wood. But it’s not uncommon in “making” $500 an hour or more doing electric or HVAC.

I assumed this was referring to the early days of the Ford assembly line

Yes, Ford claimed up to 90% in the 1930s when they were producing up to 1.4M cars and trucks per year. (Down to less than 400K in the worst of the depression.)

Still lower than farmers and their horses. :)

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…

not as much anymore. model s/x discontinued.

Most of those stories are 1/ crashes and 2/ hybrids. Again, with rare exception, manufacturers are just making gas cars with EV power trains. Tesla and BYD are making next gen transport. Are you old enough to remember when TVs broke so often that TV Repairman was a job? One day we will look back on car mechanics the same way. I do remember the visceral joy of trying to keep a supercharged Camaro on the track, but tho…

I own a Model 3 and I like driving it, but I scratch my head at everyone who claims there are no mechanical problems. I'm glad you didn't have any, but there are some repairs that are almost obscenely common. In the past year, the heater failed (PTC Heater had to be replaced), and the lateral link ball joint ball joint had to be replaced. That is about CAD5000$ worth of work. There is also an issue with a wire in the…

My Model Y headlight failed. Bought the ballast for like $125 on eBay. Had to take my dang front of the car apart, but Tesla had a really nice manual online. So it has pros and cons for sure!

> manufacturers are just making gas cars with EV power trains. Tesla and BYD are making next gen transport. From what I see online, Teslas, especially MS/MX, are actually quite like an EV-swapped Toyota than anything futuristic. A lot about their cars(exception being CT and Semi) are ICE-mass-market-car coded. They're car equivalents of ARM PCs in ATX form factor like NVIDIA's DGX Station, opposite to the likes of tr…

MS/MX have been discontinued. Their basic design was ~ 20 years old (2007)

I think model 3/y were more clean slate designs.

Now that’s an idea… I found one for my car, but kind of hate it.

I don’t have a 3D printer currently. I did help my cousin’s kid by one and they told me if I ever wanted to print something to let them know, but I have a feeling I’ll need to design my own with some trial and error.

I’ve hesitated buying one, because the idea of having a machine to melt plastic in my house seems like a bad idea when it comes to air quality.

>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.

On the other hand: If the assembly is reliable- enough , then repair isn't normally something that needs to be pursued in the first place. Like Honda engines on their myriad pedestrian cars. I'm sure there's exceptions, but the engines tend to be ridiculously reliable. The rest of the car often fails (due to age and/or rot and/or deferred maintenance and/or crash) and leaves a very good engine behind. Accordingly, ju…

That's an interesting turn of phrase ...

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.

I don’t think BYD would be a hit in the US as they are in Europe. It’s an entirely different market. They may be relatively successful just not to the point of taking an important market share, they would probably be like Mazda. Many of the subsides for Chinese EV ended this year too, and they are now realizing price alone is not a differentiator. So even if BYD eventually makes it to the US, they will be priced clos…

> It’s an entirely different market One without cheap cars or EV's, even though that's what people want and need now.
