The average people don't buy BMW or Tesla, they buy Honda CR-V. And they'll appreciate 500mi range far more than being able to take turns fast

Zero people drive 500 miles in a straight line on a daily basis though, so cornering ability is more important than 500 miles of range, especially when most gasoline cars (several diesels do) don't get that much range in a single tank. The biggest change for EVs is the ability to charge the car at home, though, so you wake up every morning with a full tank of "gas". An EV with only 50 miles of range would do great fo…

Not even driving through Norway's or Switzerland's mountain roads has made me ever factor the cornering ability of a mass produced car into the equation. It doesn't matter outside of places you are putting a car's dynamics to its limits, the only place I know you should be doing that is on a race track.

But don't forget to make it app only, because we don't want to build charging network which would be actually useful.

The UI should be: you plug in and it gives you power and your credit card pays automatically. Done. You never need to touch or see your credit card or phone at any time before, during, or after the charging process. Guess what kind of EVs work this way already.

But I need to put this credit card info into a car which I don't really own and then my "butt" starts randomly buying FSD. No thanks.

Haha ok. My car doesn’t have my credit card info and never has, but to be fair it is in an associated account, so your point still applies.

I completely agree that chargers need to have simple payment methods, but doesn't the largest public network (Electrify America) already work this way? Yes they have an app, and you can get cheaper prices if you pay their subscription, but you don't need to use it. You can just pay with no account using the card swiper on every charge point, I'm pretty sure.

I’d rather not swipe a card or use an app.

As opposed to what? Paying with cash?

If your concern is trackability, then I'm pretty sure you can buy pre-loaded credit cards that are as anonymous as cash.

If you are concerned about convenience, it sure seems to me that swiping a card is easier than buying gas with cash is.

-edit- Oh you mean the Tesla thing. That's a nah from me dawg. I don't mind having the option, but having that as the _only_ method of payment is _incredibly_ anti-user.

I dunno. Honda doesn’t offer an electric CR-V, but they’re coming out with the Prologue, which is slightly cheaper than the comparable Passport. Passport: $43k Prologue: $48k - $7.5k tax credit.

Tax credit shouldn’t be included as it is inconsistently hard to get, and not available across all markets. Checking Honda dealership near me, g there are configured CRVs that can be driven off the lot for $35k, without even considering that you can almost always haggle for good dealer markdowns on ICE cars but not EVs.

Ignoring tax credits, EVs were cheaper to comparable ICE vehicles when I did my calculation earlier this year after factoring fuel savings. But that is, admittedly, going to depend on the individual person's driving habits and fuel prices in their area, as well as their electricity prices. We drive a decent amount, our fuel prices are high, and our electricity prices are low, so we were close to the perfect combination of factors for EV. That is likely not the case everywhere.

For me, that ended up being ~$100/month which was decidedly more than the increase in monthly payment. And that's ignoring that the savings continue beyond the end of the payments.

It's also ignoring used vehicle prices. When I looked, and again, in my area, the difference in price between used vehicles was larger than in new.

This. I've done 4 3000km road trips in an EV. I never went more than 200 miles between charging sessions because my family and I need to eat, sleep and toilet. So more range wouldn't have made the trip any quicker. Faster charging would have. Add a bit of margin and I believe that 300 miles is the point at which charging speed becomes more important than range.

But if you’re at something like 600 miles that’s basically the maximum most anyone is willing to (or should ) drive in a day (10 hours at 60mph average), so that means you can use destination AC charging instead of DC fast charging because you now have 8+ hours of sleeping time instead of wanting to keep your break time under 20-30 minutes or so. This is why I want my first EV to have a range like that. I’ll be able…

This increases the stakes that your destination charger is available too, right? I can see having a large range is good for anxiety, if and only if you keep it in reserve.

I.e. plan to charge with 50% or more remaining, and have a low probability option to skip a charge and drive to the next destination. Then, your plan has to adapt as you may have to stay there longer than intended to wait for this much larger charge deficit to be recovered.

If this large capacity battery didn't have charge speed limitations, perhaps the mitigation could be to take a detour to a fast charging station and then return to your planned route.

Mercedes achieved a 1000km range with a regular 100kWh battery by making an extremely efficient car with a drag coefficient of only 0.17 [1] [1] https://en.wikipedia.org/wiki/Mercedes-Benz_Vision_EQXX

The unfortunate thing with the whole drag-coefficient game is it ultimately results in fish-shaped cars and zero unique designs. Between EVs and crossovers we're suffocating in this current era of uninspired automotive design where it seems like mfgrs take a single car model, open it in Photoshop, resize by 50/70/110/130%, slap on new badge and call it a day. Audi & Subaru are some of the worst modern offenders here.

> fish-shaped cars and zero unique designs

While the EQXX and the Aptera EV [1] may both be fish shaped, they show quite a range of design variation.

This seems like cool technology, but I can't help but to believe that people are concentrating on the wrong problem. Range is important up to a point, but the more important problems to solve are 1) a recharging infrastructure that makes it so that EVs don't need such huge batteries in the first place and 2) recharge speed needs to be at the level of plug-in, use the bathroom, un-plug and go.

Recharge speed is there already. 20 mins is enough to get 2 - 3 hours worth of driving. We just need more of these fast chargers rather than lots of slow ones.

Considering I charge at home I actually save time overall vs filling up my old diesel in daily driving so stopping every 2 - 3 hours is fine for occasional long trips. Also I spend about 1/5th per mile too.

Most people coming from an ICE get hung up on the range however. They think they need something that does what they have already.

A 1000km EV range is not news. Aptera is winning the 'range war' with a 1000 mile (1600 km) EV. And recent battery news should be taken as 'new ice cream flavor discovered' announcements. What is the actual interesting bit of news here? Their proprietary BMS doing DC to DC seems somewhat trivial.

Aptera hasn't delivered a car yet.

Neither has Our Next Energy. There is no news here.
