I’m gonna go out of the box here and say General Electric, mainly because they’re a huge corporation that has the wherewithal to see the project through (aka no vaporware), and they have a long history in providing solid electrical products.
Yes, there are the likes of Sony, Samsung, LG, etc., that are more modern giants in electronics, but they’ve already got their hands in the automotive business.
(Hey, at least I didn’t say Lucas Electronics)
The “too big to fail” mentality is often a risky one, but GE may actually be too big to fail at a project like this. Why not go for it, introduce the world to an EV free of modern accoutrement? Just bring this back.
