Having now watched this video and the two Jason Cammisa videos, I am so impressed with the engineering that went into Cybertruck. Incredible work that the Tesla team should be very proud of. It's unfortunate that the engineering accomplishments have been overshadowed to an extent by people fixating on the look of the truck and the Elon noise; I hope the engineers get the respect they deserve from the broader public in due time.
Bravo.
Just to build on this, for folks that don't have the time to watch, these were the highlights to me from the newest Sandy Munro video that I hadn't heard elsewhere yet:
1) They succeeded in reducing the front-casting machine size from 9000 tons to 6500 tons.
2) They engineered a solution to make jump-starting the Cybertruck backwards-compatible with 12V jump systems.
3) The higher bandwidth of the CAN system will allow for better performance of the active noise-cancellation system, among other benefits.
4) Tesla makes their casting dies in-house, and enjoys benefits from close coordination between vehicle engineers and die-makers (this enabled the reduction in casting machine size for the front casting, and allows them to make Cybertruck front casts on Model Y casting machines).
5) The regenerative braking system will utilize towing mass to improve range / reduce brake wear.
6) They mounted one of the controllers on the firewall in a way that it spans the wet and dry side of the firewall, reducing the need for drilling through the firewall.
7) Discussion of the major improvements to the power control system that enable bi-directional charging.
8) The steer by wire motors operate at ~50% power capacity which enables redundancy should one motor go out for some reason.
9) The HEPA filter is designed for easy removal by hand as a simple plug-and-play.
