I hadn't noticed that they were using the hub motors, thanks for pointing this up.  I will be a bit more cautious before I consider getting one, though I'll still keep open the possibility.  On top of the other risks they seem to be asking from their pioneer first customers, that one seems like

Wheel motors have a lot of issues, but one of the biggest is the unsprung mass ratio problem, which is especially bad on a lightweight car like the Aptera. On Sun, Jul 9, 2023 at 7:10 PM Ryan Fulcher via EV wrote: > Of course, Aptera is also "breaking the mold" with their hub motors. > Yes, Time

Of course, Aptera is also "breaking the mold" with their hub motors. Yes, Time will tell of course. And I hope that we start to see them hitting the road by the end of this year. -- next part -- An HTML attachment was scrubbed... URL:

I'm not an expert or engineer, but I suspect that we're about at the stage where it would be possible to build an EV capable of a few dozen miles of daily travel, using solely sunlight from its own PV. It might even be a bit more civilized and comfortable than the solar challenge racers. In

That is sort of impressive, however at 18mph there is basically no aerodynamic drag. And yes, a century old baker electric was already very efficient. It's easy to tell because the waste heat produced was very low even back then. The Aptera remains efficient at freeway speeds, and the differentia

I believe the Aptera should be somewhat more safe than a motorcycle. I think they have crash test data and their passenger shell is very strong. It is more efficient than a motorcycle as well. I didn't intend to get into the weeds regarding the engineering trade offs... I just thought the Aptera

An RV is a totally different case, especially one that's a trailer, as you want power for the house loads while it's parked. Keep in mind a few kWh in an RV goes a long way, but in an EV, even an Aptera, it's not all that much energy. Also, you've already "paid the devil" to move the RV with its

PV on an EV will help a little, but it is far better to put the PV on your house. We have a 1.5kW Solar option for our vans which have a large flat roof, and there is little aero penalty, and it gets only about 15 miles a day peak. We also sell a refrigerated option that's all electric, and this c
