Comparing Tesla, Ford, & VW's Electrical Architectures
Why Hacker News recommends it
HN recommends it as a fair, technical comparison and cites it when discussing why legacy automakers have more boxes and complexity than Tesla.
What it is
Sandy Munro sits down with engineers from 3IS to compare the electrical architectures of the Tesla Model Y, Ford Mach-E and VW ID.4. They discuss ECU counts, bus architectures and what the differences mean for cost and integration.

I'm not a Tesla fanboy but I didn't think it was biased. E.g.: Right off the bat he talks about the number of ECU[1] of Tesla compared to others. He points out that this will result in inferior quality due to the number of connections. A no-brainer with cascading effects which has many other advantages for Tesla[2]. Spelling this out will upset a lot of people because it's a valid attack that also knocks the other designs into a corner that makes one wonder what's the point of even continuing. (at least if one expects a ranking on quality etc - then there is no recovering from that). The missing CAN-FD[3] bus-speed info on Tesla is interesting. It seems Tesla is doing it's own thing here wit

I think it's the same with everything like agile software development etc. There are some ideas with some good parts, but the way people end up applying them can cause a lot of problems. People should understand the domain, do risk analysis, change management etc. For example car companies are suffering from chip shortages. Maybe they should have stockpiled more? But on the other hand, the "parts bin" is the worst obstacle preventing innovation and integration in established manufacturers. Why do new companies like Tesla have way less electronic parts while legacy manufacturers have lots of separate boxes and wiring, all reducing reliability, increasing cost, space and mass. Because for a le

* >and was quite a bit cheaper* There are reasons why your ID.4 is cheaper than the others (and it always boils down to quality of the parts). Take a look at this Tesla, Ford, & VW's Electrical Architectures for instance. There are other tear-downs that can confirm [this video]
