At first glance, the Aptera looks like the typical sci-fi concept car that gets paraded at car expos by the likes of Mercedes and BMW. But the design is the result of relentless optimization to make the most efficient EV possible. It came down to improving three elements: shape, weight, and charging features.
The shape is inspired by how sharks and other fish reshape their bodies when swimming close to the ocean floor to reduce their drag and conserve energy. After testing it in NASA’s wind tunnels, the Aptera turned out to have less drag than one side-view mirror on a pickup truck (according to the company). The EV also weighs 65% less because of the switch to carbon fibre materials and removing one of the wheels. And finally, the exterior is covered in solar panels that can recharge up to 40mi/60km per day.
I’m a big fan of the “less is more” approach here. It’s definitely not the perfect vehicle for every use case, but I can see this becoming an ideal commuter vehicle. Hopefully they can go from prototypes to large-scale production successfully and not run out of money. Apparently, they plan on making their first deliveries in the next few months.

Nope, F1 cars are upside down planes. They have wings to push the car into the road creating downforce to corner faster.

The most common EV barrier is price. If this thing is over $25k none of that optimization matters in the market.

Well depending on how technical you want to get… DRS is a change in the car’s shape which certainly helps it “cut” through the air faster. Also the current generation largely relies on ground effect to produce downforce rather than wings, but that’s neither here nor there. Ultimately, the cars are aerodynamically optimized insofar as any drag they do produce is going towards the production of downforce.

Looks very much like Elio motors attempt. They wanted to do a 3 wheel gasoline powered car, took tons of deposits, but never got farther than a prototype. They are now trying to do a 3 wheeled EV. I'm a skeptic until the company starts shipping actual vehicles.

Somebody asked about price. Elio is targeting $14,900 but if I remember the target for the gasoline powered version was about $7,000 and they just never got to production.

Cool design. Looks like a two seater with little or no luggage space. Range with electric cars is always an issue. Anyone know the range when fully charged? Small batteries seem to imply limited range.

1LizardWizard t1_iycwqwy wrote

Oh 100%, just splitting hairs. I agree with you, and think generally any comparison of an economy vehicle against a high performance vehicle will fail. Cars traveling at high speed need to produce some downforce, to remain stable, even where minimizing drag is their aim. I think a VW XL1 would be an even better comparison to that end, but that’s way less sexy of a comparison than F1, or the speedtail.

DazedWithCoffee t1_iycwscf wrote

Assuming you’ll need about 2KW of power for this size (e bike kits usually go up to 1kW) and those solar panels can provide about 150W (curved panels are dogshit) you’ll probably get 100miles out of this thing tops. You could probably expect to gain a mile of range per hour with full sun. This thing is another solarpunk pipe dream.

How to tell me you know nothing about vehicle dynamics without saying you know nothing about vehicle dynamics.

Putting batteries in wheels does nothing for stability, except thrashing suspension response due to unsprung weight.

The joker who wrote the article clearly doesn't know what they are talking about.

No. They are not pairing with one. They have to put the car together, manufacture them. Widget 1 connected to widget 2 is manufacturing a product. Partnering with someone to make widget 1 and building widget 2 in house makes no difference to you having to manufacture the final product.

You can go to the reservation site and the base model is $25,900. With the add on of all the solar panels (only the hood panels are included in base price) you can have a car that goes 250 miles on a single charge with the addition of up to 40 miles from the solar panels (depending on the day, location, and time if year) for $26,800.

I’m not sure that price is a real barrier, or there would be unsold EVs on car lots. I think that when supply catches up to demand, car companies will have to be competitive again at the low end. Some foreign EVs are already there but they’re hard to import. If they’re clever, car companies will use their current EV profit margins to make their future cars cheaper to build so that they can compete at the $20k level.

goodsam2 t1_iydjrhx wrote

I still think we should focus more on getting away from the car while moving towards EVs. EVs aren't as good at longer commutes and such but decreasing vehicle miles driven is key.

It's also automated electric busses are the real killer thing here. A lot of the problems with automated vehicles are because they aren't mapped or they have things in their path. This would make it a lot simpler.

Cities are wildly more efficient and people are willing to pay the premium, we should just build more and not subsidize the suburbs as much.

But cars need to do more than transport 2 people from point A to point B, and there are reasons why they're shaped the way they are:

  1. Families. They need to carry more than 2 passengers

  2. Cargo. The modern car is a workhorse, used for transporting bulky items, and large quantities of things like groceries and gardening supplies.

  3. Safety. They need to protect the passengers from injury during collisions.

  4. Durability. After a couple of bumper taps, it should only require minor repairs.

Researchers frequently make experimental cars that get tremendous efficiency from only being solar powered, and this example appears to be just a little more usable than those.

What really should be happening is improvements in urban design, not to mention changing our car-based lifestyle, to move away from reliance on cars.

Cool, I'll drive that when everyone around me decided to also drive much smaller cars with legal bumper heights. Until then I'm not going to risk Chad killing me with his rented full SUV or Tucker with his modded truck that puts his "bumper" at the level of my windshield.

There are safer EVs out there, it's time to upgrade the grid and infrastructure to accommodate these vehicles. Vote, and start writing to your officials that you want green infrastructure.

With how bad the market is right now I expect those 37k reservations to get cut really quickly. It cost billions of dollars in investment to get cars out of the door. Rivian lost $1.72b last quarter, Lucid lost half a billion dollars.

Does Aptera even has the cash flow to last through 2023?

There will certainly be a limit to the solar wattage. But if it's also energy-efficient to drive, you could stretch "how far" that electricity would go. Nothing is a perfect solution, but I think it's an interesting option, at least.

The Honda Civic price 2022 in October 2022 ranges from 23-29k

Toyota Corolla starts at less than 23k

Of the most popular vehicles sold 2022 , the vast majority are truck / suv / Tesla.

But yes the fact remains the average new car price for October 2022 is close to 50k

Nah, Americans just love big unnecessary trucks whilst complaining about gas prices. 🤷‍♂️

Anyways my point is $27.5k for a small electric SUV isn't high, especially since there are federal and state rebates.

Why? In North America, there are significantly more Tesla plugs around. There are significant advantages to how quickly it can charge, how easy it is to use, packaging, and price.

The legacy manufacturers literally came together to try to tank Tesla while also trying to tank EVs.

kdavis37 t1_iyeb8v7 wrote

They're claiming 10 miles per kWh. So 40 miles is 4kWh.

The version you don't have to charge is COVERED in solar panels. 700W on sunny days is the claim.

Their claims are perfectly reasonable for all 15 summer days you can park directly in the sun from 9-5 with no interruptions.

DazedWithCoffee t1_iyed3i3 wrote

The claim can be whatever it wants. The fact of the matter is that your available capacity on anything other than motorized tracking panels is going to be about 30% of ideal while sill having a reasonable hope of being aerodynamic. The realities of the application at hand are at odds with the claim. Also worth noting is that the kind of days that would provide this level of solar performance (assuming everything else works by magic) would also necessitate climate control for the benefit of battery pack and driver. The solar car concept has fundamental issues; I worked on a solar car competition in college and it was only possible with future solar panels, future energy storage, future efficiency gains, and zero utility for the user. Like much of what gets posted on this sub, it’s CGI wishful thinking

Cost to enter is obviously an issue, but EVs don't have to be cheaper than ICE vehicles to be more appealing. Different people place different values on future money vs current money, but only the extremely stupid/incompetent place zero value on future money. If a car saves you $20k over it's lifetime you might only be willing to pay an extra $10k for that. If you are particularly short sighted you might only pay $5k. People who don't qualify for a ~$30k car loan are probably shouldn't buy a new car anyway.

Ptomb t1_iyeh7n6 wrote

I’ve been following the Aptera for a decade and the things that are keeping it from being a reality are:

  1. The lack of a physical side mirror. California requires analog mirrors for any vehicle to be treated as a car. The onboard cameras and screens are great, but in the event of a power failure or device malfunction, there are no backup mirrors.

  2. It floats very easily. In road tests, a standing puddle with two or more inches of water can divert an Aptera’s trajectory at speeds as low as 20mph (30kph). Running water presents an even higher risk.

  3. Crosswind stability. An uplifting wind, like what you get when driving along a cliff or hillside, can significantly alter the direction of the Aptera.

If these three issues could be resolved in an economic manner, we may see them everywhere (especially in my garage).

kdavis37 t1_iyehlaj wrote

I have literally talked directly with the founder of Aptera and told him exactly the same thing. Just the weight of the panels mean they could have increased the range by more than the 40 miles they could get in their ideal scenario.

phatelectribe t1_iyekgoz wrote

They don’t need to be cheaper, just the same price or even slightly more given the running costs and maintenance are far far lower (no filter changes, no oil changes, no timing or fan belts, etc etc). People will spend more upfront because over the life of the car they spend far less. That why prius became so popular - they were $10k more than the same ICE car but you saved $20k in gas over the 5-10 years you owned it.

The Ford F150 Lightning and Rivian R1T each can go about 2 miles per kwh. The Aptera can go 5 times as far on the same energy. You could fit maybe 50% more solar panels on a large truck (the Lightning is 30% longer, the R1T is 22.6% longer) so with the extra panels it could maybe go 12 miles per day in full sun. That could still be useful.
