How is 250 enough. On roadtrips I can easily go 500 miles in a day. With 900 miles you could go on trip and return home before you need to charge your battery again. With this sort of range it might actually make EV pickups useful. You can now probably tow an RV 400-500 miles in cold weather with this. If this is legit, it’s going to revolutionize everything.

Or could you add extra capacity like drop tanks for fighters in WWII. Use built in 259 mile range normally. Rent a 900 mile range extender pack for your cross country trips.

Who is going to move a 500 lb battery?

It is 1500 km translated for US readers.

It's interesting that HN discussions overwhelmingly use Imperial/English/American/whatever - to the point where people sometimes don't consider that metric is common in the real world. There's a fairly international and highly technical population here.

In this case, I think it has more to do with an overly cynical tendency on HN to assume everyone else is a bad engineer.

932 “must” come from a lazy performance calculation because they came in assuming it is wrong and that is the first error they think of

…why? I get range anxiety is a thing. But no one needs that kind of range in a car. Why not make it 400mi/650km and save a ton of weight? The battery here gives double the range of an Accord. Who needs that? Less battery is less weight. That’s better for tires, roads, charge times, brakes, accidents, acceleration, drivability, cost, and probably more. 250mi is plenty. For most even less. But there’s a psychological f…

Aren't batteries kept in best condition under 80% and above 20-30%? That high capacity number might be for a taxi and they'd have a lower more standard one for normal commuters.

It's still quite meaningful. It's the distance you could allegedly drive without recharging.

Drive what though

The car.

Lexus is Toyota. In Japan, they are branded as Toyota, hood symbol and all. They just market them differently in the West. The same thing goes for the Acura / Honda distinction.

Below I'll use "Lexus" to mean those cars that get branded that way when marketed is the West and "Toyota" to mean to the ones that get branded "Toyota" in the West. I'll use "the company" when referring to Toyota the company rather than non-Lexus cars the company makes. I'm curious if there is any difference within the company other than branding. Are they built at the same factories, or are there separate factories…

Anecdote:

Friend of my had a Lexus IS220 (in Europe). His rear bumper got torn off.

Next day he arrive at work. We all go and look at the damage. And indeed, no bumper. You could see the frame rails.

And what was stamped on the frame rails? That's right. Toyota.

How often are you driving 1800 miles in a day.

Truly autonomous cars could drive you cross country while you work, eat, sleep and consume entertainment all within the car. With those kinds of efficiencies it's pretty attractive regardless, but very short charging breaks would be even more attractive.

A fully autonomous car charging robot would be a solution for that now.

Fall asleep in your van, car recharges every 300 miles via robot, 3 days later you are on the other coast.

> EV buyers may want to consider a used EV until new tech comes out, since old or current tech is not always worth paying new prices for. Sounds like exactly what Toyota is hoping for with regular press releases like this. Shutting down competitors electric sales while consumers wait for this someday-tech would be fantastic for Toyota. Until you can buy it, it's meaningless at best.

See links above. I don't disagree Toyota drags their feet updating their existing cars, let alone new ones. One big move is they did sign that deal with Tesla to adopt the supercharging standard for electric. Hopefully that speeds things up.

Toyota is running ads explaining why a battery vehicle isn't the best choice. Right now.
