Was very concerned until I realized you were talking about kilometers and not miles. Otherwise, I'd hope the average driver would firce themselves to drive slower than 120mph out of some sense of fear, or at l…

Miles are bigger than kilometers so the guy doing 90 among traffic that wants to go 120 might actually be worse in miles because it's a larger speed differential.

...that...that was his point...

Do all Toyotas do that? I'm pretty sure that my dad's Corolla will rev the engine when I press the gas if the engine is already running. I'm also surprised for the first few minutes when I drive it how little "engine braking" it has (my habit is from riding a big motorbike).

I know for a fact you can neutral-drop a prius. I know it's not exactly the same, but I was a teenager and curious, and you can rev them and shift into drive with some heel-toe finesse. Not sure if this works on the newer ones, this one was an early 2010s model.

Thank you for performing the experiment I didn’t even know I wanted to know the results of before now.

Yes this is why EV brake pads last 2-3 times more miles. They aren’t being used due to the regen braking.

I wonder how does this compare with engine braking. Many people in the comment section are surprised that their EV's pads are lasting up to 4 years yet as someone who always drove manual cars and who leverages engine braking this sound like a normal length.

Not sure but very few cars are sold with manuals anymore especially in US. Most people here under 40 or even 50 don’t know how to drive one.

which is the whole point of hybrids Part of the point, not the whole point. Regenerative breaking is absolutely a win; but there can also be a significant benefit from allowing the ICE to remain in the RPM "sweet spot" rather than moving around a larger range.

This is the thing with good hybrids. The "gas pedal" becomes a "I want to go faster/slower" pedal, its position has zero impact on the RPM. As an anecdote: A security company I know only buys Toyota Hybrids for their guards just because of that. They have a habit of driving cars like they stole them and normal ICE cars break down from that kind of abuse. Hybrids won't let you abuse them, they pick the RPM and you dea…

The whole "pas pedal" becomes faster/slower (one pedal driving) is coming to an end. Its being banned as default in the world's largest EV market (and largest EV export country).

That same insight applies to regular hybrids, and yet Toyota’s hybrids are legendary for their durability. There’s a reason half the cabs where I live are Prius station wagons, and it’s not their efficiency, judging by how they’re driven.

Consumer reports found that HEV's were the most reliable, and PHEV"s the least reliable. That's nonsensical, there's little difference between the two. Toyota is the biggest seller of HEV's, Stellantis of PHEV. That's the difference. EV's on paper should be the most reliable, but Tesla is the biggest seller of those. If you want reliability, choose by brand rather than engine type.

I was comparing a Hyundai Ioniq EV with a Hyundai Ioniq PHEV and was surprised to find more problems reported by the owners of the Ioniq EV.

Mostly issues with 12V battery, it seemed like.

In the end I bought a Stellantis EV so I probably deserve everything I get - but they are cheap!

I suppose the same should apply to hybrid cars, which outnumber pure EVs significantly [1]. The effect comes from converting the kinetic energy back to the battery charge via generation instead of wasting it via friction, which is the whole point of hybrids. [1]: https://www.consumeraffairs.com/automotive/how-many-electric...

On both my Volvo PHEVs I often look at the brake discs and find them rusty from the amount of regen braking. it almost completely eliminates conventional braking unless it's for collision avoidance.

So your primary and emergency brake system elements are rusty and that is now somehow a good thing?

See the Ioniq 5 N. But those sounds are piped inside... not blasted to the neighbors...

Can it be disabled? I love quiet

There's probably a federal or local law requiring some sound. Like the Waymos that incessantly beep beep beep when backing up at the recharging station at 1 mph. You're about five years away from hearing beep beep beep everywhere you go due to the proliferation of driverless vehicles.

First of all don't forget the important 'Over the course of their driving lifetimes' before your quote; it changes everything. So yeah this MIT article says EV is 80% more CO2 expensive to build but makes up over it's lifetime not quite exatcly what you are saying. Also this article does not take into account recycling of batteries which is way dirty that recycling ICEs. And my initial remark was show me data, show m…

> it changes everything It changes nothing. People buy cars to drive them. > Also this article does not take into account recycling of batteries which is way dirty that recycling ICEs. I'm sorry you can't be bothered to read your own link. This is in the footnotes as a source for it: Erik Emilsson and Lisbeth Dahllöf. "Lithium-ion vehicle battery production: Status 2019 on energy use, CO2 emissions, use of metals, pr…

'People buy cars to drive them' : how long did you own your last EV car ? enough to pass the limit for the EV to become interesting ? You think all Tesla & BYD owners do that ? Don't think so ! So in the end your ownership (and 95% of the other) of an EV was more CO2 intensive than equivalent ICE because you don't keep it enough to become efficient. And don't talk about second hand use because this is clearly not the way our society is going; it's all about buying new stuff and changing cars every couple of years; huge hyprocrisy when you say that EVs need time to become more efficient than ICE.

'I'm sorry you can't be bothered to read your own link. This is in the footnotes as a source for it:' just click on the damn link, use google trad, find the paper and READ (not just troll as if I didn't) the recycling chapter by yourself ! It does not include real-world data, it's theoretical/research data IF batteries were recycled in EU/US with up to date processes. As of today 2025 all batteries are 'recycled' (joke..) in China/India by underqualified people with a CO2 cost WAY higher and this is NOT taken into account in the study. So yeah I'll say again : real recycling, the one we do right now IS NOT ACCOUNTED FOR !

Useless discussion anyway, you don't add any argument or source, just trolling on my words, nice !

It feels like we are still trying to convince ourselves that EVs are a good idea. Progress is too slow and too painful.

The best thing I saw was some Kia beating a Ferrari on a race test on instagram. What was great about it was the the commentary. The comments were all about how beautiful a ferrari was and no longer about its exceptional performance (which is the original raison d'etre) - and a lot of nostalgia complaining about how EVs are going to be the death of beautifully engineered cars.

Yes I know the KIA is only faster during acceleration and theres more to cars than acceleration/top speed that ... but the commentary was too funny. It made ferrari look like a car from the past.

For DIY EV conversions (I built some cars) you usually hook up the "regenerate braking" to the brakelight switch.

So as soon as you tap the brake pedal just a little, you start regenerating and see the amps flow back into the battery (I have a little display on my dashboard). Only when you press the pedal further, do you start engaging the friction brakes.

I have no statistics on brake pad differences because we didn't build enough cars/didn't cover enough mileage to measure, but it is obvious that you would cut down on brake pad usage.

Everything I know about EVs and the tech behind it I share on: youtube.com/@foxev-content
