Nice find! Clearly set up for future add-ons.
Thank you for watching!
I am really hoping that we see the developed Elaphe 50kW hub motor used when Aptera brings back the AWD feature. Potentially, a tiny 6-7HP motor could get superior range. But if they are going that way, I would prefer having the options of either the tiny eco-motor, or an additional 60HP to give buyers the option of more range, or more performance, in addition to the enhanced the safety and control of AWD.
I think we will see the Elaphe motors return in an Aptera 2.0 or larger version. If my guess is right maybe they could have a higher HP rear motor to fit in that location. Thank you for watching!
Any analysis of the Aptera is always welcome, I've seen a comparison video of the motors but not too much of a deep dive.
An idea to consider, Thank you for watching!
I think the rear motor idea outlined has some interesting potential, especially if it is set up to function as described. I’ve hypothesized numerous times if that is something that could be retrofitted to the LE fwd Aptera as an OEM kit. Lots of possibilities!
A mild rear motor would be fine.
I hope this is the solution, lighter weight, better efficiency, and the AWD benefit when you need it.
Wow great observation, makes sense and agree!
Thank you for watching!
Besides an extra powered wheel for very low traction scenarios, the main advantage to a rear motor is traction for acceleration and a high torque low horsepower motor could add a lot of low-speed traction. Anyway the battery will probably be a limiting factor on maximum power and thus acceleration at higher speeds, and the low drag aerodynamic design will allow great acceleration and high speeds, with tires and safety limiting maximum speed.
When I get my Aptera, it would make a great video to have a tire comparison test between the factory LRR (lLow Rolling Resistance) tires and a set of performance tires. To see the impact to range and acceleration. Thank you for watching!
Interesting observation, you may be on to something there!
I hope I am, it would give the best of both worlds. Better efficacy, and AWD control when needed. Thank you for watching!
I think that this rear drive will be optimized for efficient cruising at highway speeds. It can of course also add some torque and traction at start up and lower speeds, too.
I would think so, the best of both. Thank you for watching!
Very acute observation. The other option I see is what is used in just a handful of motorcycles. CanAm just came out with a new electric motorcycle (the Origin) borrowing technology from their electric go-cart and snowmobile technologies. A single sided swingarm which houses an enclosed chain/lube system with the motor mounted on the pivot point of the swingarm to the frame, the location reducing 93% of the "squat" (rear end squats down on rear suspension when you give it the beans) most motorcycles have. This takes the weight of the electric motor away from the unsprung weight while the sealed chain inside the swingarm reduces maintenance. The anti-squat feature helps to put the torque to ground, which is more important than lots of HP as you have mentioned in those low traction situations, it would also help from transferring too much weight away from the front wheels. The chain is probably more efficient but it could also be belt or shaft drive which other motorcycle manufacturers have use. The picture of the Aptera, although not too clear may indicate a parallelogram type of suspension as you've indicated which has also been used on motorcycles (i.e. BMW, Yamaha, Ducati, etc.). But to me, this is the placeholder for for all wheel drive and improves suspension for the front wheel drive. See Fort Nine's excellent coverage of the Origin here: ua-cam.com/video/--lGOPT0kZM/v-deo.htmlsi=9pcmz8w7PGrMaQjs
Thank you for the comment, I was unaware that CanAm had come out with an electric motorcycle. I will definitely watch Fort Nine's on the Origin. Thank you for watching!
good analysis. seems like you could be onto something.
although i don't care about all-wheel-drive personally and rather have vehicle that's cheaper.
Also, something about your microphone situation is making audio comes through not the best, kind of muffled and bit hard to understand.
I think this could give the best of both worlds, increased efficiency and lighter weight for those who want AWD. Thank you for the feed back on the audio, it is a problem we are trying to solve.
I am still wanting to see a flat change…don’t think it’s going to be easy!
When I get my Aptera I will make a video covering that concern. Thank you for watching!
One of the Aptera videos showed the 'cartoon version' of a rear flat tyre change. In theory it seems easy. In brief, the rear wheel fairing comes off, and then the lug nuts and the flat can be removed
OK! This writer likes your theory and hence you have a new subscriber. The "Solo' three wheel EV had the motorcycle rear suspension, and the thing hopped like a scalded rabbit{see the Out of Spec. review of this EV}. A sheer layman's view of the new suspension is ; its possible. There is no place in the chassis/body to place a third electrick motor and run a chain/bevel gearing or? out to the wheels. Another review/thoughts on the new chassis is welcomed. Its a fine diversion of the mind till we see the REAL THING basking in the sun of our driveways- we hope in 2025 and not 2525!
Thank you for subscribing to the channel! I have seen the Out of Spec. review of the Solo and I think his video is the best to show the issue with a rear swing arm. I was lucky enough and had a chance and drove a Solo and it was very Rabbit like. I hope to pick up my Aptera in 2025, it will be a Suna day!
I look at that same casting and see the bolt-in location for the bevel gears housing of a shaft drive unit to join to a chassis mounted motor. I like your idea better, since bevel gears are hugely inefficient.
I see what you are saying, like a shaft drive system on a motorcycle.
Tho bevel gears are less efficient wouldn’t they’d allow for a less bulky, thus more aerodynamic rear wheel housing?
@@gr8dvd And have less weight on the lone rear wheel?
@@harriettanthony7352 True but the center-rear placement of battery pack should make for a stable ride. In contrast my 2nd car was a (moded) 1969? Corvair, rear-engine… always carried a case (or 2) of oil in the front trunk for stability.
Interesting "find"! Would love to hear how the 7 (or whatever) hp motor mounted inside (or adjacent to?) the rear wheel would power the wheel. Would it be fixed to the stationary arm with a (very short) axle to the wheel? Would it be small enough to fit inside the rear wheel skirt without modification to the skirt?
I would think, or how I would accomplish adding the motor would be that the motor would bolt to the arm with the 4 mentioned bolts. The output shaft of the motor would have a splined end and engage a hub bearing like what you would find on a FWD car. I would think that the bearing would be the same for all configurations to reduce part count, cost and warehousing. The motor would need to be an induction motor so it can "free wheel" to reduce drag, this is the same type of motor Toyota uses in there rear AWD system.
I would think this motor would fit without a need to have a unique rear wheel skirt. Because of the cost of the tooling to make a different skirt side for maybe only 25% of owners wanting AWD. I am getting that percentage number from Toyota's estimates of their AWD system demand.
@@ApteraAccessories Thanks for the "hypothesis". From this naive eye (er, ear), it sounds like it could work (and fit). Yes, I would think that it would have to fit in the FWD skirt (i.e., the same skirt for all configurations) for the resasons you mention regarding the bearing.
I didnt follow. Are you saying the rear motor would be mounted in the chassis, rather than the rear hub? How would it drive the wheel? What kind of mechanical linkage?
From what I am seeing I think the motor would be mounted inside the rear suspension arm on the left side and connect to the hub bearing on the right side of the Arm to drive the wheel. Thank you for watching!
I thought it was a mount for a rear facing articulating machine gun attachment.
I'm still not gonna buy until they have in wheel motors
I see the benefits if the hub motors but I would rather have an Aptera in my driveway and upgrade when they make a 2.0 version with the hub motors. Also at that time it would be fun to compare the 2 side by side. Thank you for watching!
When the lower body and frame were being made they knew about the motor swap and had them built accordingly. This wasn’t very transparent to those $10k investors knowing they wouldn’t get the three in hub motors all along. What they should s let those who wanted the hub motors wait until Alaphe are ready to build them yet number them as the early release vehicles.
True but man they really need to just get something on the road. Aptera is still very very under the radar, and like 90% of the time I make someone aware of aptera and their mission they want one too. From what I've seen they plan to do fwd later on. As long as it doesn't flop again thats all that matters
I like that idea. I would also be interested in just a rear Elaphe motor if the product rate is the limiting factor
With the accelerator program you have the option to defer your delivery until the AWD option is available if you want. I think the Elapha motors will be seen in a 2.0 or larger version of the Aptera. Personally I would prefer to have AWD but I am not upset with the change. And if the solution is to have a mild system like I hypostasize in the video I think its a better solution. AWD control when needed and better efficiency. Thank you for watching!
For a 3-wheeled car it is not the best solution to have the single wheel being powdered to drive down the road. I will be covering this in an upcoming video. Thank you for watching!
the rear went a redesign because the open wheel differential afforded by the new motor adversely affects driving dynamics. Normally in FWD cars equipped as such the rear end has an antiroll bar to handle most of the load balance but Aptera does not so their rear suspension is going to have to do a lot more work. to be honest their "four point" rear is not special or innovative.
I think there is more to the redesign, I have never seen an anti-roll bar on a single wheel. The purposed of a anti-roll bar s to control/ reduce lateral tilt of the car from side-to-side. Thank you for watching!
It is becoming very disappointing how Aptera is deleting key items of interest.
That's because the whole thing is vaporware 😂
@@paul9156c If all they has were renderings, you might have a point. They have a lot more than that, and you don't have a point... except perhaps on top of your brain-box.
Everything that's change has had very good reasons. The hub motors weren't going to be produced in time or to the right quantities as elaphe (however you spell it) lost a lot of their other contracts for making those motors.
If you were on the list to get one of the Accelerator Aptera with the change to FWD you have the option to defer your car until the AWD system is available. Personally I would like to see if they system could be added after purchase. Thank you for watching!
If only aptera was transparent
I think they are very transparent for a startup, but we don't have to agree.
@@ApteraAccessories- Aptera is transparent because they keep repeating that they are. Thus most of the transparency are fluff stories. Yet when I’ve been asking them for a year about the frame, they just talked about the bink. When people asked them about the 20k motors they needed to order (as per their SEC filing) they went silent. Yet instead they had a big surprise that they were not going to use them.
So, when you crowdfund, you are required to show progress even though it’s pretty much just to show that as opposed to what you actually are going to sell.
@@billsmith5960I've been around tech startups, did one myself, and change is something you can count on. That's my experience.
@@ronfarnsworth7074 @billsmith5960 So selfish. There must be a Committee for Understanding Normal Transparency Standards and you, billsmith5960 should be the head commissioner.
@@billsmith5960 me me me
If they were planning on a rear motor, why did they announce all 3WD orders were now being filled by FWD-only silly trikes?
Because that have decided to not launch with the Elaphe hub motors and changed to the FWD Vitesco EMR3 drive axel. I think having a Mild AWD system with a similar solution to what Toyota uses is a future plan once production starts and they have more capital to develop it. Also have a rear mounted induction motor that is only powered when needed would increase efficiency.
And if its possible to retro fit the parts onto a LE (Launch Edition) I will show you how I do it on this channel!
The troll-boy from down under doth whinge too much, methinks.
@@GullWingInnMoclips Convince people you think at all first. How does one whinge with a question? Riddle me that.
@@aussieideasman8498 You have made your online presence based solely on whinge-bitchery over Aptera as far as I can tell...... so see any of your posts or videos for the answer to your disingenuous bleating question.
@@aussieideasman8498 Your channel has the feel of someone whose girlfriend was stolen 20 years ago and never got over it. Did one of the founders slight you, you poor thing?
Earned a subscriber. Adding a motor to a rear wheel is not a difficult thing. The AOC discord unfortunately has a moderator bias that prohibits discussions like this video.
Thank you, I think the discussion is positive!
