    Many have asked about Aptera Motors, a car that's seeking maximum efficiency and using solar for added range (this EQXX also has solar, though only good for about ~2kWh per day, or about 25 km). I have a video on the Aptera solar math, seeing if it checks out! Here's the link: ua-cam.com/video/7L1_zvqg73Q/v-deo.html

      We can see the problem though. It does not, as you put it, 'look like a car.' There's no point making a more efficient car if it isn't going to sell, and not many people are going to buy a car that makes them look like a weirdo.

    • @Speeder84XL

      I would say it's still quite slow - just 90-120 km/h for "highway driving" (not even 130, as the speed limit in big part of Europe). The test run in the example, also had an average speed of just 83 km/h on what mostly looks like highways. But, at least it was a normal car and not some specially build thing on bicycle wheels travelling at 40 km/h. It was at least tested and optimized at speeds where the aerodynamics comes to play. So that gives an idea how it would perform at higher speeds as well. But still, it would be nice to see some autobahn driving as well (which have been done with Tesla) - to show that it can keep good efficiency even at higher power outputs and that there isn't any issues with the batteries not get enough cooling, as some cars have.

      @@martini380 Yes I do.
      Of course average speeds is highly dependent on traffic conditions and which roads there are are along the route. If it's country roads with lots of traffic where it passes thru cities at several places, 83 km/h average might be very good (almost unreachable)
      - but since this seemed to be mostly about highway driving, that was what I referred to.
      During low traffic conditions and mostly highway, I often get average speeds of of 125-140, even with a slow cars that top out at no more than 160-180 (and more with quicker cars)
      With more traffic and slow drivers in the passing lane, it get's harder to get good average speed of course, but the traffic need to be quite bad to not being able to get at least 110.
      Yes, "normal conditions" can be heavy traffic as well, but that will also introduce a huge amount of random variation. The 90-120 km/h marked on the graph, wouldn't be at all relevant in those conditions anyway
      - because the speed will vary widely as traffic congestions come and go. Especially for drivers like me, who like to push it when the passing lane do get free (even if it is just for short stretches), haha
      A huge amount of test would need to be done and averaged out to make that a meaningful test.
      The easiest is to do this, is when the disturbance from other traffic is low - so the driving can be done in a resonable predictable manner. If that was the case, an average of 83 is like crawling (for me at least), haha

And in the Hot summer with the AC drawing power, you risk battery thermal problems. I'm sure the car will just shut down if the batteries get close to thermal runaway temps which will leave you stranded on the side of the road... That passive cooling is a very bad idea.

Also I know what ozone damage is and you resolve that by using improved tyre compounds but that is an atmospheric issue. Unless the tyre would be contacting the surface of the side cover creating static build up from the friction, but that is just incompetence and something you would not see on production cars and you don't on the rare occasions they cover wheels at all.
      as for the floating mass, unless its a panels with just a few flimsy fitting points this is a non issue unless you use a bad design of course but most just integrate it into the body as non removable. From what I can tell all these problems are a by product of carelessness, Covering wheels is nothing new and has been done plenty so unless you can give me real word example where this is actually a problem that has no straight forward solutions you just doing a what aboutism.

      It kind of goes against the whole purpose of building an efficient car though since your charging speed is extremely limited. People want lots of range for long trips, but if it takes 2 or 3 times longer to charge it, then the entire trip ends up taking more time. They built this car to be the most efficient as possible on a single charge, but in the real world the battery would likely overheat extremely quickly under high acceleration and deceleration.

    It'll be cool to see more cars like this. The Aptera although not something in mass production would be cool to see a comparison at highway speeds. Obviously, that really doesn't look like a car and has in wheel motors 🤔.13 drag coefficient though.

      Aptera is a motorcycle, not a car. So it does not make any sense to compare it to a real car.
