I heard last week they are looking into adding an optional, single “child seat” in the center behind the passengers. Nothing decided yet.

However, crash testing will come only after all the other testing. Only after they think they have a production ready design will they crash test them. Crash testing incomplete prototypes doesn’t prove anything.
Right now they are testing the 1st beta’s production intent suspension system, as they mentioned in the December update.
Another beta will be built to test the HVAC and innovative cooling systems. They got seat designs and other parts to test, too.

Got a “404: document not found” error when I clicked on that link. Looks like the forum software munged it to include the link twice. Maybe this will work?:

The charging circuits for DC fast chargers is a heavy piece of equipment in a steel cabinet in or around the DC charging station, never in the vehicle. For AC charging, the charger is part of the vehicle.

So Joshua, how far do you ordinarily drive on a trip between stops?
ModeratorMay 5, 2022 at 1:08 pm
Daniel, how do you figure that 25 KWH, 250 mile version is no good for any longer trips?
How long are your trips?
The way I figure it, you leave on your trip starting at 100% charge. After going 90% of range (up to 225 miles) fast charging back up from 10% to 80% will take 70% of 25 KWH, or 17.5 KWH (175 mile added range, not including the solar boost). At a 50 KW fast charger that takes about 17.5/50 = 0.35 hours = 21 minutes, after over 3 hours of driving — a nice rest stop.
The 400 mile version could take you that much further between charges, but then require longer to recharge to 80%.
My longest trips are almost never more than 4 hours of driving per day, about 250 miles, usually with over a half hour stop for a meal along the way.
Writing this, I’m talking myself out of the 600 mile version I reserved into the 400 mile version.

Account hacked by a “friend”?
Not a helpful post. April Fool’s Day was over 2 weeks ago.
Really, EV batteries are already being recycled. Aptera runs on the cleanest source of energy.

Have you noticed that quite a few cars made in smaller volumes have composite bodies (as Peter mentioned above last November)? However I’m guessing they are more like your boat body than Aptera’s.
What’s really new is Aptera’s use of 3d printed molds and UV cured foaming resins in the vacuum formed composite body molding process. My dentist uses a similar UV cured resin on my fillings. The basic UV curing technology has been around for over a decade in the epoxy/glue industry, but the cost has been high.
The UV curing speeds up the hardening process from hours to minutes, making an assembly line of 40 cars per day possible and economical. You won’t get 40 boats per day with traditional fiberglass epoxy methods. I understand Aptera has some patents pending on their process.

I agree if the category is “… in a 4 wheeled vehicle”. They would be legit records if the category was “… in an electric vehicle” or “… in a solar powered vehicle” or “… in a self powered vehicle”, even.
That last one is pretty open ended, however. Then Aptera would be competing with motorcycles, mopeds and e-bikes, too, as well as airplanes, boats and trains.

You a Physics major? Not too many folks think in “joules”.
The nice thing about KWH is that is the unit of energy everybody’s electricity bill uses, so we know what it is worth.
I pay about 12 cents for each one (includiing 5 cents delivery charge and taxes).
ModeratorFebruary 17, 2022 at 3:46 pm
Simple Physics and Newtons Law, F = ma, or Forcee = mass times acceleration.
Solving for acceleration we have a = F/m.
If you know the mass (they do) and the force (calculated from the known torque of their motors), they can calculate their acceleration. (Easy peasy.)
I read that Chris Anthony stated those accelerations apply to their heaviest 100 KWH battery Aptera. The others should be faster, as long as the tires don’t slip.

I’m an Electrical Engineer that has researched a bit about Lithium battery charging. Here is a bit of info on the subject. If you want to learn a lot I on the subject I suggest the free Battery University website, https://batteryuniversity.com .
When a battery company specs a number of recharge cycles, they mean from 0 to 100%. So if you are going from 75% to 25% and back to 75%, for example, that counts as half a cycle.
But it’s better than that, because the worst stress and aging of a battery is time spent near 0% and near 100%. By keeping your battery away from below 10% and only shortly above 90%, your battery will have a low stress, long life.
Keep it in the middle of itts charging range for the longest life, and keep it cool, by allowing it to run its climate management. For most EVs, that means keeping it plugged in when you can, especially if it is hot out, like over 85F. But then if it is not full, even getting hot won’t be much of a problem. Teslas automatically run their battery cooler when their batteries get warm, IF the battery has a higher charge. Hopefully Aptera will do the same.

When you click on “My Account” (in the upper right corner of this screen) and then scroll down, do you see a line labeled, “Review orders”?
What do you see when you click on it?
ModeratorFebruary 10, 2022 at 6:42 pm
Joshua, I think you’re really under selling the Aptera. Let’s do some math.
The Aptera is capable of powering 3, 50 KW motors. That means up to 150 KW, at least for a short burst of acceleration.
Perhaps a better measure is its top speed of over 100 mph. Burning through over 0.1 KWH per mile, that’s burning through over 100 * 0.1 KWH = 10 KWH in 1 hour, so that’s more than a steady 10 KW for an hour. At that rate, a full 100 KWH battery will last for 10 hours.
However, Steve Fambro has said the inverter power out will most likely be limited to much less than that, perhaps 1.5 KW = 1500 watts — more like what a normal US home 15 amp 120 volt outlet will do.
At that rate a full 100 KWH battery would last over 66 hours, more than 2.5 days.
ModeratorFebruary 9, 2022 at 10:49 am
But I got to ask,
How many places are you planning to go to that are more than 500 miles away from an electrical outlet?
A 110 volts outlet is all you need to get 150 miles overnight. (See the FAQ.) Stay less than 3 days to fully rechange from empty at that speed.
ModeratorFebruary 9, 2022 at 10:41 am
Don’t know where you got that “at least an hour to add 300 miles” from.
Take a look at this site’s FAQ page, under the Efficiency category. You’ll find under, “How quickly does Aptera charge?”,
“At roadside charging stations you’d likely get about 100 miles in 10 minutes.”
That works out to 600 miles per hour.
So 300 miles is added during a quick lunch or fast food break. Then you’re good for another 4 to 5 hours of highway driving.

If you hover your cursor to the right of your name on the post you’ll see 3 vertical dots. They bring up a little menu and one of the options there is “Trash”. Click on it to delete your the post.
I deleted one. I’ll leave the other for you to try to delete. Let me know if you have problems.

Nothing illegal about not meeting forward looking plans. If it were, most companies would be illegal.
With a Harvard JD, Mr. Anonymous Yale grad, I’d think you’d know the definition of legal terms and the importance of truth telling.
Aptera Motors Inc. (the previous version, now defunct) didn’t ever declare bankruptcy, leaving debts unpaid. Rather, they liquidated the company, paying off all outstanding debts in full, including paying back the deposits of all reservation holders. When the old company did that, it was after the founders Chris and Steve had already left the company over strategic plans after losing control to the management team brought in by the venture capitalists that invested in the company.
Reporting this post for violating this forum’s rules of behavior. Personal insults are not welcome here.

They already are connected with electrical cables and cooling hoses (and the suspension arms). We only need to make them reasonably strong and well connected. No way are Aptera wheels by themselves going rolling down the road.
