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.
Can't wait to see a teardown of the Tesla Roaster, I heard Elon put it somewhere safe though.

I wonder if the secret is Musk not creating a huge layer of bureaucracy above engineering on top of a decent amount of funding, so they can really accomplish things.
Na, he just makes a randomly selected engineer ride up with every Falcon 9 first stage booster. Half of the engineers are hoping they get picked, the other half are scared shitless, but they all give 110%.
Statler and Waldorf have moved from their previous job of reviewing live shows https://www.youtube.com/watch?... to reviewing cars at Munro & Associates . .When reviewing the new Tesla Model 3 they "still cannot find the gas cap after 3 days" and hooking two jumper cables to 12V to open a trunk "more complicated than programming my VCR , I never figured that one out either".
Both found that the BMW I3 the "most advance ever" with a electric range of 114 Miles and a 2 cycle generator option for extra range that gives off enough smoke "so you know it is working"
Just claim it's for transporting "dreamers" and instead of throwing you in prison, CA will throw you a parade.
