Tesla Model 3 Torn Down, Hacked and Set On a Dynamometer, Exposing Unusual Tech Details (electrek.co)
Rei writes: With an estimated 8,670 Model 3s delivered, a race is on as competitors and owners work to figure out its limits and explore the tech behind it. Many-time Tesla teardown expert "Ingineerix" has posted a series of videos and discussed his findings on Reddit. Among them: what appears to be the industry's first switched reluctance motor, a massive "smuggling compartment" allocated for a future front-wheel motor, no physical fuses (all solid-state), significant wiring harness length reductions via the use of multiple body controllers, a swappable crash energy absorption system, a liquid-cooled compute unit, and redundant controllers for all safety-related systems. He followed up by posting a screenshot of the car tricked into "factory mode" to reveal its internal specs, including a 1200A max discharge current, 370kW max discharge power, and a 76 kWh pack with 72,5kWh usable. Meanwhile, Munro and Associates tore down a Model 3 for an undisclosed, "not Tesla" client, releasing a video criticizing its build quality and for difficulty in accessing the HV cables in the event of an accident (Munroe's claims were dismissed by Ingineerix). Meanwhile, engineers from German automakers were extremely impressed by what they found during their teardown -- particularly the power electronics system, which they described as "compact, expandable, fully integrated, modular, easily accessible, well-protected, reasonably priced and astonishingly clever in many details." Other owners have been putting their cars on dynamometers to measure their power. Drag Times suffered some skid and measured a conflicting 281 / 327.6 hp with 552 lb-ft torque. Contrarily, Tesla Repair Channel found consistent readings around 250hp when starting from 30mph, but consistently around 390 hp when starting from 10mph. The reason for the discrepancy is not yet clear.
The model 3 is merely superb tech because Musk duped a whole lot of good engineers into working for his hoax product line that is never going to take off.
Or something like that. I'm probably not the best at Musk bashing but hope that I got the spirit right.
Fanboys are funny.
I mean, really, it has a PMSRM, not just a simple SRM. You know how impressive that is? Let me tell you, VERY IMPRESSIVE. It also sculpts and enhances the field to increase torque density. How about THAT? Impressed yet?
Nah, it's just particularly egregious in this case. It is always amusing how Tesla drivers are invariably rich people who drive them to their 7,000 sqft homes and their equally large vacation homes. So much for saving the environment.
You are right. I don't, because I don't care to know. But think of this: what the difference does it make to YOU that an expensive car for the 1% (that you will never be able to afford), uses a PMSRM instead of a SPM? I mean really, who cares? How is it improving the human condition? There are many people out there who are really changing the way we live in a meaningful way. You guys are obsessed with the cult of his personality. It is you that cares about totally irrelevant things.
Reality check: if you are living in a 220k home you ARE part of the 1% in the world. That is a big problem with you guys: you have no context of what the world is like. You go on and on about things that don't matter.
The fact that you think that a 2200 sqft house is "modest" is very telling. There is nothing like the insular stupidity of suburban Americans.
The 1% loves Teslas because the whole Ferrari thing is old hat. They get to virtue signal that they are cool and hip and about the environment, and drive around in a relatively rare car (because Tesla can't get the production right). Oh, PLUS they have a couple of SUV in the garage too.
Here is another fact that is going to SHOCK you. Electric cars are not sustainable. No really, they aren't. Having a private car isn't sustainable. It is a luxury for the 1% in the world. I know, you are going to get really upset by that (but "mah freedom"). Nothing is wrong with having a private car, but to say it is "sustainable" is a joke. Having it cost $75k - $150k is just more of a joke.
