Short version: WTF is "DataRay"? (from here) Long version: I listened to the recent earnings call, and something caught my attention. At one point Mr. Musk was speaking about the Model Y and how it would not be built using the same platform at the 3. That alone was quite shocking to me, but a detail slipped out that was even more interesting to me professionally. He went on to half-mumble a few sentences on that point. He clearly said that the Model S has 3km of wiring, the 3 will have 1km and then the Model Y should have around 100m of wiring. To do that, he mused, you'd have to change the system bus. Whether or not they'll be allowed to do that I'm not sure (in the US and Europe, there are certain regulations regarding this but I'm sure he's more up to speed than I am), but I'd be more interested in HOW. He said that CAN bus (current system) doesn't have the bandwidth (which isn't completely correct, but it is if he wants to get down to 100m). Now... that's all I heard. There was something else inaudible that I didn't catch. Apparently some media source did (or did they?). I saw this article where they say: Wait, what now?!?! Where'd they get that from? And what is that? I immediately googled it, and other than a couple other references to that same Tesla earnings call (and probably all reporting off each other) I see NOTHING in terms of a data bus called "DataRay". There are various other unrelated things by that name. I consider myself relatively in touch with this sort of thing. I've worked on several automotive parts projects and I'm familiar with CAN and its ubiquitous use in the automotive field (again, due to regulations - as well as it being a reliable, robust and proven topology). I'm aware of a few potential future candidates for a CAN successor, but I have never heard of DataRay. Was this an ignorant reporter's typo? Or did I somehow miss something in my own field and my GoogleFu is not powerful enough? Anyone have any leads for me? If "DataRay" exists and Tesla is considering using it, I'd like to get out ahead of this. ps. From the name alone, I'm wondering if the author meant FlexRay. If so, that's by no means revolutionary or new. It has advantages and disadvantages vs. CAN and I don't really see it helping Mr. Musk reach a 100m goal. But the name is similar in form?
