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.

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.

The rear brake rotors on my Yaris hybrid are basically always rusty because they get used so little. After some time you just know when to start braking so you only use regen instead of the brakes.

It does. My Volvo XC60 T8 PHEV is a 400bhp 2.2 tonne SUV and after over 5 years of ownership the pads are about 20% worn. And I don't drive like a granny either. The car just does most of its braking with the EV motor.

And manual transmission cars kinda, though the energy is still wasted of course
cloverich · 1h ago
Surprisingly you can get nearly same effect in automatics. I put around 60k miles on my first automatic (after120k+ on my first two cars, manual transmissions) and when i got my brakes checked at 63k they noted my brakes were still "brand new". I do gamify reading traffic to try and brake as little as possible (to help pass time etc), but was still surprised how far this takes you given i do plenty of stop and go traffic driving. This was a v6 sedan so lighter than an suv / truck. I expected it to not work in automatics but it does to at least some extent. I swapped for an EV before taking it the usual distance and curious if anyones pushed further and how far.

No reason for it not to work, even more so if you think to downshift. It’s more common with manual as downshifting is a lot more natural but not fundamentally different.

It’s just trivially easy with electric thanks to regen braking.

Though with modern cars getting heavier if you have a small ICE these days you have almost no engine brake which makes some cases more difficult (unless it’s a mild hybrid with an electric kers like some of the small engined fords). SUVs tend to have giant engines and pretty high rolling resistance, which I’d think would somewhat compensated for their higher inertia.

It’s all about learning your car’s behaviour and planning for it.

dotancohen · 25m ago
I don't know about today's engines, but some early fuel injected engines would actually use more fuel when engine braking. In those early designs spark could not be cut off, so if this extra fuel were not added then the mixture would run very hot and risk pre-ignition and damage. I don't know about carbureted vehicles.
MindSpunk · 50m ago
It's not "nearly". It's exactly the same effect. Compression braking. Even if you're not on the throttle the engine is still rotating as it's connected to the wheels. If the engine is rotating it is compressing air. If it's compressing air but not igniting fuel (throttle closed) then it will suck energy out of the wheels to compress the air.

You can do it in an automatic, you just have to force it to select a lower gear using the gear number options (1, 2, 3, 4) or using the tiptronic mode. The lower gear means the engine will displace more air in the same amount of time, increasing the rate it pulls energy from the wheels.

People think you can't do it in automatics because they try very hard to keep engine RPM low where the effect is diminished.

OptionOfT · 1h ago
Depends on how you drive. I never engine braked on my manual. Brakes are easy to replace. Clutches are not.
MindSpunk · 1h ago
You don't engine brake with the clutch, you engine brake by downshifting and using the higher engine RPM in lower gears to brake the car via wasted compression.
dotancohen · 23m ago
And that downshifting involves a clutch operation, moving the engine into a higher RPM. That most certainly wears down the clutch, talking as someone who's replaced quite a few of them.
throwawaysoxjje · 8m ago
Are you really shifting so much that your clutch slip in the middle of the shift effects clutch lifetime?
eptcyka · 1h ago
You need not burn your clutch to engine break.
hassaanr · 1h ago
engine braking does not have any effect on the clutch, other than while downshifting, which if you're blipping/rev-matching has practically no effect
ajross · 2h ago
To some extent, but not really. Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop. My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the car at the end.

> Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop.

This seems a bit exaggerated. Staying regenerative-only does require sticking to about half or so of how fast I could stop, but so far that seems to work fine unless a light turns right in front of me or traffic acts up. Usually it says it gets high 90's or 100%, and it didn't go below 50% even when a stoplight did turn at exactly the wrong time. (2022 Ford Escape non-plug-in hybrid, recently bought used.)

CraigJPerry · 53m ago
100% of possible system capacity to accept regenerative charge on a smaller battery system will be a smaller absolute number than 100% of possible on a larger battery. If you assume everything else is constant, motor, inverter, battery C-rating etc.
tbrownaw · 42m ago
The manual says it's energy recovered (ie, not something relative to system capacity), and this seems consistent with the other indicator that shows instantaneous braking power with a distinction between what the regenerative system is doing vs what (if anything) the traditional brakes are doing.
dotancohen · 20m ago
If your Model Y is like my Model 3, then it seamlessly switches to friction breaking below 20 kph. That said, I'm at 110,000 km and the brakes look like new.
Swizec · 2h ago
> My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the car at the end.

My manual car could do this 20 years ago. My fully ICE motorcycle can do it today.

I know engine braking is cool but it’s not some amazing new thing only EVs can do. Altho granted it only produces heat and noise in petrol vehicles. But it also makes your heart sing so that’s nice

We finally gave up our Prius after 12 years, and we never changed the brakes once. The brakes were just peeking into the yellow on its last service upgrade. I was really impressed with how well the "normal" hybrid could take advantage of regenerative breaking, honestly.
Helmut10001 · 1h ago
I first changed the brakes on my Mitsubishi Space Star (combustion) after 13 years. It is a small car, less than 1000kg, so there is little for the brakes to do. If we produced more percentage of small cars, many environmental risks would be reduced. And btw.: The tires are now 19 years old and still good (less weight, less abrasion!).

In normal driving hybrid regen is more than enough to do the job. Just look at the front wheels of any Prius. There are reasons all the Uber drivers choose the Prius.
cyberax · 1h ago
You can just waste energy on eddy currents, and then use the car's cooling system to conduct away the heat. After all, dynamic brakes on locomotives just dissipate the generated electricity using resistors.

Hybrid makers just don't really care about that.

bruce511 · 1h ago
I don't think this comment should be down-voted since it is indeed a real point of difference and it is worth discussing.

The key takeaway is that there are differences to driving an EV to driving an ICE vehicle. Equally those differences are in fact easy to adjust to given a bit of practice.

Of course cars have always had different control options. Automatic and Manual gearboxes spring to mind. When I first learned some cars had a gear selector as an arm on the steering column, and so on.

EVs like a somewhat gentler foot, because the torque is instant, so a heavy foot is likely to be a more uncomfortable ride.

So yes, different cars, different styles. But of course we adjust very quickly, and its not really difficult to drive anything- it just takes a bit of practice.

Many electric cars are also overpowered. For those with a more reasonable ~100kw, gentleness hardly matters.

> you have to constantly ride the gas pedal.

Are you not? Do you drive by blipping the gas every few seconds?

I've had Uber drivers do this and it is annoying bordering on nauseating as a passenger. It is probably pretty bad for mileage and transmission wear as well (constantly taking up and releasing the backlash in the gears).

rgmerk · 1h ago
Firstly, most EVs that have strong regenerative braking ("one-pedal") setups allow you to adjust the strength or turn it off. Tesla, as usual, is the outlier in this respect.

Secondly, I rented an EV for a week and by the end of it actually preferred the strong regen setting. It was convenient in stop-start traffic, and on a twisty road, you could use it to tighten the nose as you entered the corner.

NewJazz · 1h ago
As another data point, I've owned PHEVs and EVs for gosh 6 years now and I still prefer the "weak" regen with the Chevy paddle brake to modulate. Sometimes when I have a clear path, e.g. a down hill on a highway, I just throw it in neutral for a pure coast and shift back into drive when I need to.
cloverich · 1h ago
To be constructive, took me a little over a week to get used to. Also i test drove four, and absolutely hated 2 of them. One felt very similar to my ICE car (VW ID4). Eventually settled on ioniq and after a week, it quickly became my favorite driving car ever (which coming from sporty manual transmissions, is not at all what i expected or why i bought it).

All to say, check out a few to be sure, im still shocked how much i love driving this thing (and how criminally fast it is, totally absurd).

An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.
ghushn3 · 3h ago
What are you doing to your tires that they only last 10k miles? I think that might be a driver error issue, because my EV (a heavier sedan) basically never needed tire replacement barring me running over a screw or something.
brtkwr · 2h ago
Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer
HPsquared · 2h ago
Some tyre compounds wear a lot faster than others (though often with better grip). I wonder if that's contributing.

The other thing is poor alignment (especially toe settings) which cause the tyres to fight each other constantly. It can be a very small difference, almost imperceptible but still accelerate the wear.

10k miles is very short for a tyre.

Often you can tell a lot from the tyre temperature after a drive: if they're getting very warm, it can indicate problems, e.g. if one axle has much warmer tyres than the other (hard to give an objective standard on that, though, so many factors)

thedougd · 2h ago
Aren’t higher speed rated tires softer? Maybe try swapping for a lower speed rating unless they plan on driving it at extreme speeds.

foepys · 2h ago
Are you driving fast(er than with a ICE vehicle) in corners? Since EVs have a very low center of mass, drivers tend to take corners a lot faster than they would in ICE vehicles which is very hard on the tires.

A friend got hit by this as well and since readjusting his driving style (read: not flying through corners for the fun of it) he gets more (but still not equal) miles on his EV's tires before he needs new ones.

Some EVs have low rolling resistance tires to increase the range. I think they will wear out faster, especially if cornering sharply.
slt2021 · 1h ago
remember, your regenerative braking comes at cost of tire life.

If driving Tesla, you can reduce the regenerative breaking from Maximum setting to Medium.

this will reduce regeneration and will increase the "breaking distance" when you just let go of accelerator pedal.

but it will increase your tire life significantly.

also make sure to buy the "commuter tire" models - tires with high mileage warranty (50k miles+) and harder compound. Even if it wears out faster, tire manufacturer's warranty will make up for it by giving you discount for the replacement tire purchase

mikestew · 1h ago

No, it doesn’t. The tires don’t care if it’s the car’s motor slowing things down, or some friction material grabbing a disc.

NewJazz · 59m ago
I guess they are saying that the sharper braking curve that is default on Teslas is going to cause more wear than a slower braking curve. The logic makes sense, but I have some doubt's that sharp regen breaking is more to blame for tire wear vs. Sharp manual braking and acceleration.
avalys · 1h ago
Huh? What do you imagine is the tradeoff between regenerative braking and tire life? Are you suggesting that stopping the car with conventional iron brakes is somehow easier on the tires?
slt2021 · 1h ago
the level of regenerative braking directly impacts your accelerator pedal behavior.

by reducing regeneration, you will increase tire life by virtue of modifying your acceleration behavior. Its hard for me to explain, but I just suggest trying the medium regenerative setting and you will see it yourself.

You will feel it, because the most of the tire wear happens when car decelerates. On less regeneration your car will decelerate less and will wear out tires slower

djrj477dhsnv · 1h ago
That's a whole lot of assumptions based on what?

I could come up with a list of plausible sounding reasons why regenerative braking leads to less tire wear. Unless you have some actual measurements, I wouldn't trust either one.

tbrownaw · 50m ago
I'm reading it as referring to a setting where the car will brake some amount (instead of coasting) if you completely let go of the pedals, and as being a claim that the commenter can't maintain speed but gets stuck in a cycle of accelerating and then letting the car brake.
djrj477dhsnv · 41m ago
I've never driven an EV, only a hybrid a few times, but I thought for all cars with aggressive regenerative brake settings, you just kept the accelerator pedal slightly depressed to coast.
NewJazz · 58m ago

Is this generally true? I imagine it depends on the car/driver to a certain extent, but still I'd be curious what numbers are out there.

sockaddr · 2h ago
I'm sorry but I've got two EVs and I'm not seeing anything like what you're reporting. On my first set of tires for a model S I got 60k miles which is longer than I usually like to run tires but they were still in good shape. My driving pattern is about 80% grandpa-mode and 20% speeding to loud music.

I assure you. If your EV tires are only lasting 10K miles you have one of the following cases:

- You are driving VERY aggressively

- Your car has an alignment issue or some sort of torque vectoring problem

- Your tires are absolute shit

ljf · 30m ago
He (like me) is in the UK - unless you go for a brand name, many of the tyres people run here are low quality import tyres - while 10k is low, my ICE has occasionally only got 20k from a set, but that is mainly due to the tyres cracking from sun damage (still got over 4 year out of them before that happened).

Cheap tyres are often a bad investment, but I drive country lanes with a higher risk of punctures and I was burning through brand name tyres, a full set is worth more than my car!

jillesvangurp · 2h ago
Switch tire brand and type or get some advice. Whatever you are currently getting isn't the right tire for your car, obviously. You should be seeing much longer lives for your tires. Even with an EV. So, something is off.

And tires of course aren't created equally. There are many different types of tires and they are optimized for different circumstances. If you mismatch your tires to e.g. weather conditions, you are going to have issues. Not just with EVs, but with any car.

lokar · 2h ago
There are three things at play here:

- evs have a reputation for fast acceleration, and many drivers use it. More wear.

- evs are heavy due to large batteries trying to match ICE range. More wear.

- evs often come with low friction tires to improve range, they wear faster

The second two issues should gradually go away as battery (and charging) tech improves.

> low friction tires to improve range, they wear faster

Some of the lowest rolling resistance tires also last 80k+ miles. It's not a tradeoff in the way you're claiming.

pengaru · 2h ago
> Low friction tires wear slower, not faster, on account of being ... Low friction. Friction is what wears tires.

They're not low friction tires, they're low rolling resistance tires.

Friction relates to the grip, rolling resistance relates to the heat generated by the deformation of the tire. A less compliant, often narrower tire may wear faster than a more compliant wider one.

It depends.

"Tyres account for about a fifth of the energy required to power a car. They provide friction, so that the vehicle can grip the road, but some of the power supplied to the tyres is then lost as heat. Indeed, Michelin, a French tyremaker, estimates that this “rolling resistance” accounts for 4% of the world's carbon-dioxide emissions. Tyre designers have therefore sought to improve fuel economy by reducing rolling resistance. However, this not only reduces a tyre's ability to grip, making drivers take corners sideways, it also wears out the tyres more rapidly."

That’s very likely due to the tyres having less tread depth - a common trick with EV tyres to reduce rolling resistance. Michelins are the main culprit.

Of course the tyre companies love that little trick as they can pretend they are being green while selling more tyres.

Always check how much tyre you’re buying

Kirby64 · 1h ago
The biggest problem for new EV drivers, in my view, is that EVs generally have extremely good traction control systems that prevent chirping due to the ability to cut back power to the motors much more quickly than you can with a gas engine.

What this means is that you can push tires to the absolute limit and not chirp them (which, is best for traction anyways) which absolutely roasts them. Most people associate chirp = too fast, but with EVs you can never hear a chirp even when you stomp on the accelerator so they might think everything is ok.

Nobody should be shredding a set of tires in 10k miles in any EV unless they’re super low tread wear (poor tire choice, hard to do that bad), there’s an issue with the car suspension, or they’re just being idiots.

If the steam engine were to stop faster then it would put more wear on the tires. Imagine if it were floating through space. You hit the brakes. Did it help?

The tires are doing the stopping. As you said the engine is the part that doesn't matter. But if it increases the stopping power, it's doing that by increasing the load on the tires.

Brake pads are small parts that last for years. It is nothing compared to the number of tankfuls of gas that an ICE car goes through over the lifetime of its brakes.

Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.

>drastically removed brake dust

It will be very interesting to see the data for the same car that has many powertrain versions for example the Lexus UX with the UX 200 (ICE), UX 300h (hybrid) and UX 300e (EV) to test which one the best and the worst in term of brake dust residue.

My hypotheses is that for brake dust residue the best is hybrid, 2nd will be ICE and the 3rd will be EV. This is due to the fact that the EV version has at least several hundreds kg extra weight (about 400 kg extra), that makes the brake dust residue comparable to ICE if not worst based on the approximately 30% extra vehicle weight for the battery. The hybrid however only has approximately 5% more weight or extra 80 kg different compared to the ICE version.

I would love to switch to electric but at current charging times and absolutely horrendously incompetent grid deployments, there’s no way all of the thousand people in my building could, much less the million other renters in the city. (And certainly transit can’t cope with us either, given the continued homeowner hostility to paying taxes for such things.)

What city has charging available for an average of greater than one spot per five hundred multifamily-housing residents? What parking garages anywhere in the U.S. have 25 or more electric vehicle chargers per 100 daytime and/or overnight and/or reserved parking spots, in order to diffuse the grid cost through trickle charging? What funding model is proposed to ensure that’s built whether corporate garage owners like it or not? How will states who depend on fuel tax to keep roads in repair avoid cutting off city services to suburban outregions when their asphalt budgets crater?

Technology has downstream effects, and it’s not as simple as “buy a Prius” when you consider U.S. non-homeowners. (I assume the prospect for India electric conversions would be much worse, too.) “Ban combustion vehicles” is a lofty goal, but until the charging grid problem is solved, it’s an unattainable one.

Level 1 charging overnight on a standard 120V outlet, while not ideal, is surprisingly adequate. Granted, many people rely on street parking or otherwise don't have a parking spot that is right beside their dwelling, but for rented houses or complexes with private garages/parking areas the size of the lift isn't necessarily "get upgraded service and a bunch of 240V EVSE put in".

None of the apartments I've lived at had a 120V outlet near my parking spot that I could use.

I'll second this. We got a Chevy Bolt a couple of years ago, and I assumed we'd need to install a 240 V EVSE, but it turns out that regular 120 V 12 A charging is totally fine for us. I think there's been one time in the 2.5 years we've had it when we had to go to a nearby fast charger because the battery was getting low.

Of course if you're commuting 2 hours every day, things will be different. But for us, it's been great.

stouset · 2h ago
Public EV chargers are pretty widespread nowadays. Not as much as gas chargers obviously, but for most people in the country if you don't have a way to charge at home it's not fundamentally that different from not having a gas pump at your house.

Plus, most people can charge at home with an extension cord. It's not particularly fast, but you should be able to get 4-5 miles an hour. In the worst case scenario where you can only charge at home and can only charge for 10 hours overnight, that's still 40 miles of driving which is enough for a lot of commuters. Even if it falls short—again—you can use public chargers.

Lastly, eliminating the sale of ICE cars will be a pretty rapid forcing function on the deployment of EV chargers. Still, I'd be all for locations that ban combustion engines mandating that landlords provide EV charging facilities.

It is the low temperature performance that make most EV impractical. A Tesla power pack heater means the charge will be completely depleted if left outdoors for more than a week in winter.

You could possibly have come to an arrangement about getting a 50 Amp (think dryer plug) hookup in the garage and provided your own charger. Also depending on your driving patterns a trickle charger in a 20 Amp socket may have worked for you as well. Mine takes about 48 hours for a full charge on the trickle charger.
jjayj · 1h ago
There's no garage, and the only driveway-facing outlet is at the front door - opposite where my parking spot is allocated (an extension cord would have to go under/through the landlord's cars.) I have to drive 60km to work every day.

Only laws (accommodate EVs and/or WFH) or spending time sitting at a gas station will help me here. No landlord is interested in accommodating an EV unless it's a net benefit to them (and thus a net negative to me, who already spends 40% income just to have a place to work.)

Why is your civic infrastructure so crippled? I'm not sure if I'd trust driving over bridges or drinking water in a municipality which is incapable of installing electric plugs.

With home charging, I'm almost never charging anywhere else. Maybe a few times a year when doing a longer trip. I just drive, and plug the charger in some times when I get home. I literally never think about range or having to drive a detour to fill it up.

But you have to do that probably weekly. And then also spend a lot of money while doing it. It seems you believe those driving EVs are "suckers", but do you realize you probably spend hours and hours more in a year going to the station and pump compared to most EV owners never having to do that in their daily life?

I don't think banning combustion engines is fighting the right battle, but incentivizing the alternatives (e..g lowering or removing sales tax) is a good idea.

I mean even campfires and smoking in public have negative externalities which cause cancer. The marginal cost of each is tiny and probably hard to price, but it has a price. Adding this price would slightly offset the cost but more importantly act as a disincentive for buying a polluting vehicle.

tsimionescu · 1h ago
While I think there is some merit to what you're saying, you're forgetting two major diferences between driving am ICE car and an EV charged on fossil fuel electricity.

First, EV engines are far, far more energy efficient than ICEs. Secondly, fossil fuel power plants are far more efficient at converting fossil fuels to energy than ICEs are (since the energy efficiency of a thermal engine is proportional to its volume).

The result is that the EV car mileage you'll get by burning 1t of oil in an oil power plant is much, much higher than the mileage you'll get from that same 1t of oil in ICE cars. I'm not 100% sure if this holds true for coal based power plants, but those should be getting relatively rarer.

Not to mention, fossil fuel power plants can have much better filters and some CO2/CH4 capture technologies, so the mileage you get per ton of greenhouse gas emissions is even better than the energy per ton of fossil fuels.

bruce511 · 1h ago
I'll add that Hawaii currently generates 20%+ of their electricity from non-fossil fuels. Plus they are actively reducing fossil generation with a view to removing it completely.

Changes on this scale take time. But to make the islands much less dependent on fossil fuels, a two-pronged strategy is in play. Reduce fossil fuel generation, but also reduce the dependence on fossil fuel in transport.

As a long-term strategy, reducing the cost of importing all that fuel, over vast distances, seems to be a huge win for the islands. In every way (politically, economically, socially, environmentally) generating their own energy is a win.

I don't agree with a ban, but burning crude oil (are you sure about that, it's usually refined at least a little?) can have centralised carbon capture and filtration, whereas cars pretty much just pump it straight out.

Yes, this, it depends. It has to be in the middle 100mm or so of the tyre, and not between the treads, otherwise they won’t plug it.

Annoyingly, plugs are not perfect either: after a tyre has been plugged I’m putting air in it like every 2 months, so anecdotally I guess the plugs leak really slowly.

Almost all tire wear comes from accelerating and decelerating. Some from turning and cornering. Basically anytime you are asking them to stick to the road when the car's velocity is changing. Just coasting in a straight line does not cause any significant wear, regardless of weight. (Unless the tires are grossly under-inflated.)

EVs eat tires when people drive them like they're on a race track, which is most of the time.
