Don’t they heavily compress the hydrogen with special tanks and compressors? Making it really cold, for example, makes it easier to compress.

BMW tried that. You weren't allowed to park the car in a garage, because it had to vent the hydrogen as it thawed. https://www.youtube.com/watch?v=AouW9_jyZck

I see way too many Toyota battery articles for a company that can barely put out an EV. They're all promises... in the future, they swear they'll beat everyone, but they just released a Lexus EV at $60k with 196mi range and 5sec 0-60.

Overcompensating from their statements that EVs were a fad and hydrogen was the way to go?

1000 km battery, 10 minute charge? I'm suspicious for many reasons. If they can't build their prime hybrids — or even supply gas Siennas in Canada — I'm not very confident about their manufacturing in the mid-term. I hope I'm wrong.

For a 150 kWh battery, 10 minute charge to go from 10% to 80% SoC means charging at 600 kW or so. It would be pretty insane.

It is but it's not orders of magnitude away from current chargers. The fastest I know of are 350kW currently.

Not feasible on even 240 Volt AC at all, would have to be high voltage all the way to the charger as the cabling is unworkable. Its completely impractical otherwise and its going to require big changes to the grid.

DC fast chargers are already 400V or 800V, so we’ve long since crossed the limits of AC charging at home.

Most of Europe is connected to 400V 3-phase grid.

When limited at a pretty common 40A, this delivers up to 16kW.

Tesla Superchargers routinely charge at 150kW.

I'd say they are well above 800V.

Toyota is one of the top innovators in the world when it comes to manufacturing. The reason Tesla is able to produce millions of Model 3 is partly because they are applying the lessons learned from the Toyota production system (TPS). Toyota have a lot of experience of electrification, they just have not produced a lot of vehicles with a charging plug. Toyota will deliver EVs that good enough to compete with all other manufacturers and their EVs will come with the hallmark Toyota reliability. The reason that their current EVs have so low range is pure conservatism from their side. The batteries are over provisioned and the current iterations of EVs are more of a Prime without the gas engine than a pure EV platform. They are the tortoise. Be wary of betting against them.

I wouldn't hold my breath for something called a "Corolla". Their roadmap is a big gaping hole for the next 3 years. However, this exists, and kind of looks like a tall Corolla: https://www.toyota.com/bz4x/

What's the model called? I think someone accidentally base64 encoded it.

> Why do you feel it needs to be faster? Because there's nothing I hate more than a car that doesn't respond when I try to accelerate.

The amount of torque you get and how fast you get it is what you care about then, not 0-60 times. They're not really related. There are cars with good 0-60 times that have terrible fast-secondary/highway acceleration; cars with big turbos, for example, and overly aggressive throttle-input smoothing (for mileage.)

I don't get it. The faster a car accelerates from 0 to whatever speed, the higher acceleration it has. How could it not be related?

Depends on the year, it used to be around 11s, latest models brought it down to 8-7 seconds. Normal ICE cars are in the 12-18s range, sometimes 5s is ridiculously fast and that kind of acceleration should _never_ be used in the middle of traffic or city roads.

You might want to check your facts. The 2022 Honda Odyssey minivan (not a small vehicle) has 0-60 of 6.5s.

I looked it up and that car has a 3.4 V6 engine with 280HP. Hardly a “normal” car, at least outside the US, this is entering sports car territory.

This very much depends on how low your gas prices are subsidized to, and as you admitted the lower maintenance costs are quite helpful. One catalytic concert theft will add a couple of years to that schedule, too.

Gas is usually heavily taxed. Maintenance costs are absurdly exaggerated (especially when compared to the long-term cost of battery replacement) and catalytic convertor theft is covered by insurance.

Gas taxes are about half of what they’re supposed to be to find road maintenance. The rest is subsidized out of general fund revenues.

Re: maintenance costs every reputable analyst says that EVs are significantly cheaper throughout the entire lifetime of the vehicle, even when you factor in the higher tire wear and tear. That doesn’t factor in the disruption cost of having to get service, either, which adds up with every extra visit unless you live next to the repair shop.

Finally, yes, insurance covers some costs but you’re paying money into that pool. Everyone I know has been complaining about premiums going up due to thefts disproportionately affecting ICE vehicles and a lot of people have been paying money out of pocket trying to harden popular targets like Priuses because parts were in short supply.

>Note established driving range includes aerodynamic and vehicle weight improvements. While some of these improvements rely on a switch to electric, I would love to see as many of these implemented in a much shorter term.

Yeah, as an American these things are always surreal - I grew up in the 80s when vehicles were getting heavily optimized for air resistance and weight so it’s weird seeing it as an improvement for vehicles to get … lower MPG than the car my dad bought when I was in elementary school and the most popular models are basically “what if we took a brick and added macho decorations along with a 40% markup?”
