I guess… Aptera’s vehicle is much more innovative and much closer to production. What makes this car interesting? I can’t find the specs but it looks like a regular vehicle with solar on the roof which I don’t think is a very practical idea.
About 80% of all effort for the Lightyear cars is in efficiency.
You have the obvious, like weight and aerodynamics. But also things like in-wheel motors, which are much more efficient than normal electrical engines, since there are almost no mechanical losses. Or the rear-view camera's, which save a lot of energy on air-resistance.
Interesting. I hope it works out but I’m a bit skeptical that the conventional car chassis is practical for solar power barring some big improvements in technology. It just doesn’t have enough surface area compared to its weight and drag profile. If they pull it off that would be great but I’m skeptical they can build such a car at that price point.
