48V and steer by wire already exist in other cars.

Audi, Porsche, Mercedes, Renault, Kia, Hyundai all have 48V cars. Some of those are several years old.

The Toyota bZ4X and Lexus RZ 450e are fully steer by wire.. and Silverado EV and Hummer EV use it for the rear steering. All of those are on the market.. The bZ4X is from 2022.

Edit: I looked up the data can bus changes for the cybertruck... that's not new either. Look up "Automotive Ethernet"

Those all still have a 12V system as well.

2025 models, not current models.

Model 3 and Model Y and Model S and Model X still have a 12V system as well, lol

Model 3/Y/X are only 12V. Cybertruck is only 48V. Audi has cars with both 48V and 12V. You're not going to get the cost savings benefits of switching to 48V by having both 48V & 12V.

Please tell me another car that uses 48V for the whole electric system. Indeed there are other hybrid cars that use a 48V but only for the hybrid part. The actual benefit of Cybertruck's 48V system is that it lowered the amount of copper needed and simplified the whole system.

Then look again at steer by wire. Indeed, RZ450e seemed to have it last year in reviews as an optional packaged but now if I look on their website, there's nowhere to be found. Also, Toyota bZ4x stil doesn't have it, the plan is by the end of 2024. So yeah, not from 2022 like you said... And of course for rear steering it was always used, but the novelty in Cybertruck is the front steer by wire.

I also did look Automotive Ethernet and there are indeed a lot of informations about it, but again, tell me which cars have it for the whole system. There are indeed some like Hyundai that use it only for Entertainment system or VW for the driver assist. The main advantage of Cybertruck is that it's being used for everything which translates to lower complexity and lower cost.
