In this video at time 15:00, Nathan says they were experimenting with heated and cooled seats.
The idea is that less energy is used to heat and cool the body than cooling the entire vehicle interior.
He commented they had a weird feeling.
Aren’t these common today?
- MemberAugust 14, 2021 at 1:33 pm
As an investor and pre-order holder I’m anxiously awaiting production.
One of the key updates I’d like to know about is about the seating. Last I heard about this Aptera was looking to select a tier1 supplier for the seats, but I haven’t heard any news on this. The current pictures have the same units. Is there an update on this that I missed?
- ModeratorAugust 14, 2021 at 2:30 pm
None that I heard Bruce, but Sarah’s latest video talks about upcoming updates. ???? on content including seats
- MemberAugust 15, 2021 at 3:27 am
The front view and side view of pictures coast and codex are not matching. I still don’t know what coast and codex actually look like.
- MemberAugust 22, 2021 at 12:10 pm
I think I remember Chris or Steve talking about how the seats could be put in an upright position, yet all of the videos I have seen show the seat in a fairly reclined position. I personally have neck and back issues and do not want to be driving in a reclined position. Of course, the seat can be reclined for entry and exit, then put more upright for driving, but will there be adequate headroom for the 6’ driver that wants to drive in an upright position? Any thoughts on this?
- ModeratorAugust 22, 2021 at 3:30 pm
Seat controls should be no different that regular manual car seats with a fairly upright position possible.
- MemberAugust 22, 2021 at 3:37 pm
I’m sure the control will be easy. I’m just wondering what the head room will be in an upright position.
- MemberAugust 22, 2021 at 10:31 pm
In believe that, when they talk about interior headroom, they’re talking about measuring from the seat cushion to the roof liner – at a 90° angle to the seat. The alpha prototypes seem to fit someone 6’2″ while the betas are being designed to fit someone 6’8″ tall. But, as not all torsos are the same length (I have long legs but not a long torso and have a friend who is the exact oposite: We are both 6′ tall, but do not see eye-to-eye when seated across from each other.), such descriptions are relative.
- MemberAugust 23, 2021 at 11:44 am
It’s my recollection that every time they’ve talked about head room for a 6’ 8” person, they’ve never put it in the context of seat position. A 6’ 8” person sitting in a full upright vertical position? I don’t know. Seems unlikely. Given that the seat angle is an important factor in determining head room, I personally don’t think it should be left out of the discussion regarding the available space. You’re right about the varying torso lengths between individuals. Do we know the seat-to-ceiling length? That would be useful information.
- MemberAugust 24, 2021 at 3:55 am
The 6’8″ sounds great for me (6’2″). Anyone know if there will be vertical adjustability to the seat? I need to make sure my wife (5’0″) will be able to see over the steering wheel.
- MemberAugust 24, 2021 at 6:47 am
They’re achieving the increase by lowering the interior “floor” of the vehicle so, one would hope, this would make seat-height adjustment a possibility.
- ModeratorSeptember 15, 2021 at 5:01 am
My wife’s Lincoln MKC has it. It was a weird feeling for my backside but not so much for her’s
I assume she was use to it and I was not.
So like others things “ I will get use to it” and the use of it with with an insulated body (sandwiched foam composite) should be interesting.
No typical blowing fan? Quiet!
Our experience is living in an arid state ( AZ)
Humidity may give a different experience?
- MemberSeptember 15, 2021 at 6:21 am
The thing that would make the most difference in winter would be a heated windshield. Windshield fogging is the thing that forces me to turn the heat on. If you are dressed for winter you can be pretty comfortable without heat into the low 20s especially if you have a heated steering wheel and a heated seat. However the windshield fogs up long before you need heat for human comfort. A heated windshield that uses energy just to defog or deice the windshield without wasting it on cabin heat would make a big difference in winter energy use.
The other thing is a heat pump which will be even more important in an Aptera than in other EVs. Aptera’s have small batteries, with the exception of the 1000 mile variant, resistive heating consumes about 100Wh/mile, that will halve the range of an Aptera.
- MemberSeptember 15, 2021 at 7:58 am
The point is that they’re using a different technology to heat and cool the seats: Peltier modules. All other heated vehicle seats use resistance heating coils and/or forced heated or cooled ventilation via a blower. Sitting on a Peltier module in “cold” mode is rather like sitting on a piece of ice.
- MemberSeptember 15, 2021 at 9:00 am
Been curious about the cooled seats. Never experienced it. Is it a air flow through the seats?
Makes sense from a energy stance. In my ’13 Leaf I often use the heating steering wheel & seats instead of air heater.
side note: aptera faq does say there is a heated steering wheel.
- MemberSeptember 15, 2021 at 9:58 pm
No, it’s not air-flow. Peltier modules are “solid-state heat pumps”: You run electricity into them and one side gets hot while the other gets cold. Reverse the polarity of the electricity and the heating and cooling changes sides.
So, as I said, sitting on one that’s cooling feels exactly like sitting on a piece of ice.
My Cuisinart Yogurt Maker has one: It keeps the cultured milk at the optimum temperature for bacteria growth for twelve hours and then shifts to “cold” mode and chills the completed yogurt to stop the process. While it’s cooling, the “back” of the module radiates heat – there’s a fan in the yogurt maker that blows the heat out through a vent.
- MemberSeptember 16, 2021 at 8:34 am
How can a Peltier device be used as a seat cooler? How would you vent the heat that it produces. As a seat heater it could be fine, the excess heat would end up in the cabin where you want it in the winter. But as a cooler it can’t work unless you have a means of moving the heat outside of the cabin. If you have air ducts connected to the seat why wouldn’t you just use the cooled air from the AC. Peltier devices are less efficient than compressors, doesn’t make any sense to use them for seat cooling.
- MemberNovember 4, 2021 at 12:07 pm
Any info on seat width and height?
- MemberNovember 4, 2021 at 2:12 pm
They did mention a few details but not raw dimensions. The current alpha seats are basically for show and not very comfortable (no lumbar support). The interview with the woman from Transport Evolved discussed this. I think they also said the headrest wouldn’t be adjustable at one point.
- ModeratorNovember 4, 2021 at 4:51 pm
Nazhi, I hope they make the seats comfortable for all of us. I think Volvo makes seats that are above and beyond just about anyone’s so I’d be delighted if they used these as a benchmark for the Aptera seats.
- MemberNovember 6, 2021 at 7:57 pm
theres always aftermarket cushions and lumbar support. i said aptera should do advertising deal with aftermarket product that enhances the car by advertising their stuff as options in order configurator. they test it for approval and forum can share their experience or find such product. that way, people dont choose another car b/c they werent aware of certain aftermarket fixes, for ex. if standard seats dont help them do they prefer a another car with built in seats better for their wants. tinted dislay HUD can help as less attention shifting, more intutive, spedometer. chargers and hoem batteries, solar roof etc could be a big deal
- MemberNovember 7, 2021 at 8:56 am
I’m 6’2″ and weigh 220 lbs. I get fidgety even in good seats. Hope that Aptera goes for good quality highly adjustable seats even if the added weight reduces range some. Won’t do any good to have an efficient vehicle that i can’t drive without pain in the @$$.
- MemberNovember 7, 2021 at 10:05 am
I hope that they use power seats with profiles for both the driver and the passenger. Tesla does it for the driver only in the 3, there are no profiles for the passenger which sucks. The other thing they need to do is have adjustable seat belt heights. I’m exactly the size of the standard crash test dummy so most things fit me but my girlfriend is only 5’2. Tesla has fixed seat belt anchors which are are real problem for her, the belt cuts across her neck. We dealt with the problem by buying a seat belt clamp that changes the angle of the belt but I really don’t know how that will perform in an accident. My old Volt had a slider on the pillar for the seat belt anchor which worked great, they should do that.
I’d be happy to pay extra for better seats, it’s an option that’s well worth paying for.
- MemberNovember 7, 2021 at 10:28 am
I’m quite sure they said they would be manual seats. I think this is mostly about weight / cost savings. Aptera has really focused on cost and efficiency optimization. Hopefully the stock seats will be adequate for most and the right to repair approach will allow for replacement. This wouldn’t address things like automatic profiles but better seats and belt height could be swapped in.
PS: Optional powered seats with profiles would be a good use case for a feature discussed in other threads were “plugin apps” could be added to the infotainment. This feature is in no way confirmed by Aptera and in my opinion would be a future OTA feature added.
- MemberNovember 8, 2021 at 3:40 pm
I currently drive a Subaru Forester and like the seat height. It makes it easy to get in and out of. After a weekend in a lower rental car, I suddenly realized how important entry height is in cars. Any idea of what the seat height is in the Aptera? The ground clearance looks decent, so I assume it’s up there, but does anyone have an actual measurement?
- ModeratorNovember 8, 2021 at 7:03 pm
The designers are still experimenting with the seat design. I expect that to continue throughout beta testing. So no, the seat design, including height and height range is not yet fully defined.
- MemberNovember 8, 2021 at 7:25 pm
The door opening will be very favorable for entry, but center-of-gravity height is very important for stability in a three-wheeler, and with the two occupants making up 20% of the weight of the car, I expect the seats to be as low as is practical. Figure on 4 inches of ground clearance, 4 inches of battery module height, and 2 inches of seat padding under the driver’s bottom, and no higher.
I would expect a height-adjustable seat to be optional.
- MemberNovember 8, 2021 at 8:03 pm
The alpha prototypes have 7″ of ground clearance – we’ve heard that the beta design might have slightly less.
- MemberNovember 12, 2021 at 6:47 pm
For what it’s worth, I’ve sat in an alpha and found ingress and egress easier than my Miata. I’m 5′ 11″ and 64 years old.
- ModeratorNovember 13, 2021 at 5:36 am
One thing that hasn’t been mentioned in this thread is the configuration of vehicle’s door opening when the door is raised.
In a typical crossover like a Subaru Forester (BTW my wife loves her 2017 Crosstrek), the roof opening starts approximately even with the side of the vehicle. The Aptera’s door opening in cut into the roof by a few inches. So, in effect, the seat “comes out to greet you” more so than the typical vehicle. That plus the seat height plus how tall or wide the driver is should be part of the ease of egress equation.
- MemberNovember 15, 2021 at 11:46 am
Yes the seat height is important. We want it low for the best handling and high for the easiest entry and exit. So adjustable suspension is my preferred solution. Raise it up when going under 5 mph and lower when over 5 mph. Then include the option for free ????
- MemberNovember 15, 2021 at 11:52 am
I’d pay extra for air suspension – But the asymmilar front control arm lengths may cause alignment issues… I just want to go up to 12 inches of clearance to deal with rutted roads and rocks. But we can all dream. I think it would be a good aftermarket opportunity. Aptera air suspension kit or lift kit… Looks like they have coilovers on the betas.
- MemberDecember 7, 2021 at 5:53 pm
This is gonna be One of the Important Criteria for My Wife – Both Knees Rebuilt of Titanium and Teflon – We have Super Extra High “Thrones” In Our Home – Ahem, Seating Height of 21 Inches. Handicap Ones are Standard at 18 Inches. Bog Standard Thrones are 15 Inches. She just about Cannot get up from 15 Inches, and 18 Inches is Doable, but Uncomfortable Task to get Up.
Citroen (among others) has Solved this Problem with Their Version of Hydrodynamic Road Height.
Air Ride Shocks would Do, Wouldn’t You think? A Small Compressor, would also be useful for the Tire Pressure Maintenance.
- MemberDecember 8, 2021 at 10:31 am
Air shocks would be awesome because by setting it very high you could also potentially narrow the wheels for parking. Obviously the immediate need is getting the car out but hopefully either aptera or 3rd parties will come up with an option. Everything in the early days will be low volume but hopefully in a few years with 30+k cars made we will see interest in accessories from 3rd parties.
- MemberFebruary 3, 2022 at 1:34 pm
Wondering if this petroleum-free, plant sourced leather alternative made in the USA may be of interest for interiors and seats in the Aptera going forward. Not sure they can switch in the near term, but it would be attractive to many buyers, myself included.
PEORIA, ILL. (PRWEB) JULY 13, 2021 “…synthetic leather materials are estimated to be the largest segment of the automotive upholstery market. With its durability, quality, and tunability, Natural Fiber Welding, Inc. (NFW) and the company’s patented material MIRUM, are well-suited to displace both animal leather and synthetic leather alternatives with materials that are plastic-free and high-performance.”
“… Leveraging the strength and diversity of virgin and recycled plant matter, such as coconut husk, rice hulls, and cork, MIRUM requires no plastic binders or coating. The material is durable and luxurious, making it a well-suited leather alternative.
Through their partnerships, including BMW i Venture’s recent investment, NFW continues to disprove the assumption that in order to perform, textiles in industries like the automotive industry must include petroleum-based products. …”
