Real-world CO2 emissions of cars are 20% higher than indicated. For plug-in hybrids they are 250% higher.

EDIT clarifications:

  • the article is from the European Commission. This thing comes from a serious study based on hard facts and data.
  • Check this comment by @wooster, who reported the data.
  • Note that plugin hybrids are still better than pure ice, but they were expected to be much better.

It’s not a typo: plug-in hybrids are used, in real word cases, with ICE much more than anticipated.

In the EU, fuel consumption monitoring devices are required on new cars. They studied over 10% of all cars sold in 2021 and turns out they use way more fuel, and generate way more CO2, than anybody thought.

The gap means that CO2 emissions reduction objectives from transport will be more difficult to reach.

Thruth is, we need less cars, not “better” cars.

FireRetardant,

Regardless of how it is powered, bringing thousands of pounds of steel and plastic everywhere you go to get to work, grocceries or other daily needs, is ineffecient.

But most importantly, it spends about 95% of its life parked. Such as waste of resources and space. I hope actual automatic cars in the future will allow people not connected to public transportation to avoid needing an individual car.

FireRetardant,

Often parked on prime real estate, or in a sea of wasted spaces that are rarely ever at capacity, sometimes both.

lath,

8 billion people. Everything product made creates emissions. So the question here isn’t whether fewer cars will lower emissions, but whether whatever replaces them will cover the needs of 8 billion people without increasing emissions as much as cars do or more.

FireRetardant,

We created that thing already. Its called actvive transport and transit. Walking and cycling are nearly emissions free. Transit is still far more effecient than private cars. We just need to build a society that prioritizes these as much or more than cars.

lath,

The change has helped the areas in which it was implemented. However, in part, it has also shifted the traffic into other areas instead. It does work, but not fully. To change society and pursue it wholeheartedly, profit must be removed as an incentive or at least make it inconsequential. Otherwise this consumption/production treadmill will never stop speeding up until it breaks.

anguo,

I own a plug-in hybrid, and wouldn’t really recommend one over full electric. That said, I average around 2.1L/100km.

RememberTheApollo_,

Really? We have one and love it. What doesn’t work for you with yours?

anguo,

I don’t have anything that I dislike in particular, I just feel that by trying to be two things, it does both poorly. My main criticism is the massive weight, which is inefficient. You’re either lugging a heavy (quickly emptied) battery around, or a heavy motor and tank of gas that you’re not using (I keep mine at a quarter full for that reason). I’m not saying don’t buy a plug-in hybrid, I’m just saying that I’d recommend going fully electric instead.

RememberTheApollo_,

That’s kinda the compromise of the PHEV. It’s the best of both worlds…sorta. Yeah, lugging dead weight around compounds ICE fuel usage over the life of the car, but most people do all of their driving within a few miles of home, so even if your “E” part of the PHEV is lugging around a dead gas engine for these trips it’s still far better than running ICE for all these shorter runs. Earlier PHEV had awful battery life, 10-15 miles, but the newer ones are doing much better with ~20 miles or so. That’s way more reasonable. We’ve gone weeks without filling our car with gas, so FWIW over the life of the vehicle I think that makes up for extra battery weight when running gas.

I absolutely agree that PHEV weight, or even regular EV weight, is a serious concern. Disregarding efficiency issues the power output of some EVs is crazy, the mass and torque could be dangerous and potentially deadly.

If one can manage the infrastructure issues with EV charging, and the high price to buy in to a decent one, yeah, pure EV is the way to go.

anguo,

I agree. The main advantage over an ICE is for small trips. Small trips is also the reason my gas consumption is so low. It’s also the reason I’m about to replace the car completely for a cargo e-bike and public transit ;)

I went looking for this a year or so back and I couldn’t find any big study that looked at the lifetime emissions of motorcycles compared to cars, but the road emissions by themselves are generally about as bad because while there are fewer emissions from motorcycles, the emissions that exist are worse because the smaller engine doesn’t burn the fuel as completely. The thing is a huge chunk of a car’s lifetime emissions come from manufacturing, which I suspect makes motorcycles better, but again I never found that comprehensive study.

FiniteBanjo,

The headline sounds like an astroturf trying to convince stupid people that hybrids are worse. Perhaps the author would live a happier and more beneficial life if they were to lose two fingers as a reminder of their mistake.

set_secret,

It should be noted it’s comparing the claim vs the cars actual co2 output, which for PHEV is laughably incorrect in real world use. I’m amazed a class action hasn’t been made againts these car companies. They knew what they were doing and its nothing short of environmental terrorism levels of deceit.

That said, Plug in hybrids are still ‘better’ than petrol or diesil cars for overall emissions. The title makes out they’re worse. Which is untrue.

ddkman,

The reason a class action hasn’t been filed, is because it is not their fault. The emissions are measured in a certain way, and that is kinda favorable for PHEV-s. Of course this is besides the point. The ORIGINAL reason hybrid cars are popular, is because they are cheap to maintain, but pretty good on fuel. The fact that they kinda cheat these newer emission tests, is more of a side effect.

lgsp, (edited )

A title is a title. I added a clarification at the top post. I have mo intention to deceive anyone

Anamnesis,

Wouldn’t plug in hybrids largely depend on use? If I only use gas with it twice a year, it’s got to be better than if I’m commuting long enough to need the gas motor five times a week, right?

dillekant,

A key issue with many PHEVs is that the “P” is in name only. Their batteries are generally too weak to work without the ICE engine at least some of the time (eg high speed up a hill or when partially discharged). In my view this is quite deceptive, as many people would think (and many PHEVs allow) that you could effectively use the PHEV as a “pure” EV for the majority use case.

LovesTha,
@LovesTha@floss.social avatar

@dillekant @Anamnesis There is also too many PHEV's that are given to people as work vehicles when they have no option to plug in. Ideal, the right user and real world can all be very different scenarios.

Don't take any numbers at face value, actually understand what is being measured.

Hydrogen makes no sense in personal transportation. It’s too dangerous and inefficient.

Already exists. Extracting hydrogen is (currently) incredibly energy intensive.

ProgrammingSocks,

Stop this. There is no car that will fix it. We need to stop depending on cars entirely. They are inherently MASSIVELY inefficient by their very nature. You cannot magic away the inherent inefficiency of literal tons of metal being used to move 1 person.

ProgrammingSocks,

You’re missing the point. The issue is that fundamentally, 2-7 ton metal boxes take up too much space to ever be able to efficiently transport people inside a city, and cost so much money that people almost always go into debt to even be able to get one. Car dependency is the issue. Not the particulars of how that car works.

@LovesTha@floss.social avatar

2-7kg personal vehicles are optimal efficiency, 20-70kg personal vehicles allow for everyone to do anything (okay some of the larger electric wheelchairs blow past 70kg pretty easily, but allow me some artistic licence).

Even busses aren't amazing on vehicle weight per person: 16,000kg for 50 people is 320kg per person. Good suburban trains bring that back down to 230kg per person.

So for cars to be viable your 5 seater needs to be 1600kg max. And one needs to actually use those seats.

ProgrammingSocks,

Maybe, but even after that there is a human component, people make mistakes and need time to react and need traffic lights and such. That’s why buses are still more efficient, you only need 1 human driving and reacting which controls the whole bus rather than 10 (50 / 5) who all need to individually react.

LovesTha,
@LovesTha@floss.social avatar

I was intending it as an indication that individual cars are hard to justify.

Additionally cars have inefficiencies around parking (time/energy spent doing it, space required) that PT doesn't.

They are only a good solution when ignoring/socialising so many of the costs and prioritising things that are really not important (or from a lack of imagination of what else is possible)

fruitycoder,

I remember being so disappointed in “plug in hybrids” when I saw the range on electric they had. For me my work commute I’d almost get noth8ng from the electric side of.

D61,

Well… the hybrid car thing makes sense. How many places are built to have charging stations everywhere you’d park your hybrid car?

If you mange to afford buying/leasing/renting a hybrid car, that doesn’t mean you can afford to build out a charging station at your own home. Hell, you may not even be allowed to modify your existing property even if you could afford it.

So you wind up driving an electric car that is kept charged by a lawnmower engine burning gas instead of driving an electric car, charged from the power grid, with an emergency gas powered generator to increase your range or compensate for when the batteries’ capacity degrades.

WalrusDragonOnABike,

that doesn’t mean you can afford to build out a charging station at your own home.

You you suggesting its normal for people to not have outlets at their house but own electric cars? Haven’t outlets been standard for decades in homes?

D61,

How many feet of extension cord will a home owners association let be seen drug out on the front lawn?

What if there are no exterior outlets? You going to leave a window open with an extension cord fed through it? Maybe fine if you live somewhere without neighbors… probably a good way to get robbed otherwise.

What is the exterior outlets were shittily installed and are aren’t rated for whatever your particular flavor of electric vehicle you purchased?

Live in an apartment complex? Not on the ground floor? You gonna bust out somebody’s window to get to their outlet?

WalrusDragonOnABike,

How many feet of extension cord will a home owners association let be seen drug out on the front lawn? PVC pipe and a small shovel are cheap. Easily fixed in an afternoon. Not exactly fun and assumes the person is physically able to do that.

What if there are no exterior outlets? Most homes do, at least where I’m at. If they’re in the back, that might not be practical still. Depending on the situation, adding a outlet could be less than $100. Which, if you can afford an electric car and gasoline, should be pretty affordable. But adding a dedicated circuit would certainly add more expense.

You going to leave a window open with an extension cord fed through it? Maybe fine if you live somewhere without neighbors… probably a good way to get robbed otherwise.

People put entire AC’s in their windows. There’s ways to ways to lock windows that are partially open 100% of the time.

What is the exterior outlets were shittily installed and are aren’t rated for whatever your particular flavor of electric vehicle you purchased?

If its just the outlets, fix it. A GCFI is like $20? So just replace them if they aren’t already GCFI. Bigger issue is amps in the circuit. Unless it happens to be on a 20amp+ circuit, there’s not really room for other things to run at the same time I think and it would probably be better off on its own. Also, if you have a lot of people there and have two vehicles you want to charge overnight, each would need its own circuit.

Live in an apartment complex? Then its not your home to be building a charging station at. A lot of apartments in the last couple years around here have been adding charging stations (including the one I’m at).

Of course situations vary. So, its not always practical or cheap. But you don’t need a fancy level 2 charging station to charge a plug-in hybrid.

daq,

I don’t think your assumption is right at all. Me, and I sure fucking hope 99% of other people who bought a PHEV, charge at home. Because if not, why the fuck did you massively overpay for a car when you could’ve gotten the ICE version?

My car is basically full electric for 99% of the time because 50 miles of electric range I get is plenty for daily driving in city traffic.

I just don’t want to waste money on full electric because somehow they are still treated and priced like luxury cars despite most of them being equivalent to cheap cars in build quality and materials.

I also want to avoid the hassle of spending too much time at charging stations during long trips because I have kids and just want to get places. And please don’t tell me there are a ton of charging stations without wait. I constantly see and hear from my friends who own electric cars how much of a pain it is especially during holidays. And I live in CA, easily one the states most prepared for electric cars.

PatFussy,

This is an odd article. I remember my old college buddies who worked in car emissions told me how they test. They drive different cars around taking samples along hundreds of miles. The article kept iterating that the values are different from what is collected in a lab which I don’t think is true. I also have a feeling there’s a bit of sample bias here but fuck if I know.

If all is true from the data it just shows that Europeans are not charging their cars appropriately. Could it be that there is no charging infrastructure there? I have a hybrid and I can go months without putting gas in the car…

gayhitler420,

Shot: the plug in hybrids are still lower in tailpipe emissions in concrete terms than than the ice vehicles.

Chaser: the plug in hybrids have real world tailpipe emissions that are almost exactly what the ice vehicles are rated at

Morning after: this study doesn’t include the emissions from production of a new car

ByGourou, (edited )

Wow I knew hybrids were not that great and WLTP would be off, but 250% off how is that even possible? There’s practically no difference between plug-in hybrids and standard cars.

Edit : So people are buying plug-in hybrids and just not charging it- why ?

lgsp,

Edit : So people are buying plug-in hybrids and just not charging it- why ?

Why is the open point. Maybe the range is not enough for the majority of owners, maybe they are too lazy or maybe gas prices are too low to justify the charge?

I really hope there will be a follow-up study trying to answer this point

ByGourou,

I have both a full EV that can be charged on any standard power plug and a classic gas car. I barely ever use the gas, and only use the EV because of how much cheaper it is. I would’ve expected everyone to do the same, but maybe as you said gas is not expensive enough for most people so they don’t care.

delirious_owl,
@delirious_owl@discuss.online avatar

There is a difference. Hybrids pollute less. See the articles sources.

It pollutes less, 20% less than classic cars on average in real life use. That’s barely anything.

That’s apparently when the user doesn’t charge the damn thing. That’s a problem with the user.

Alcatorda,

At least where I live in Europe you (used to?) get subsidies for buying hybrid cars or EVs. So people would buy them for the discount and then never actually charge them 🤷🏼‍♀️

grue,

Edit : So people are buying plug-in hybrids and just not charging it- why ?

One possible reason could be that they picked a plug-in hybrid over a pure EV in the first place because they had nowhere to charge it.

Moonrise2473,

In my country all the electric charge companies made a cartel and they’re selling the electricity at 1000% markup.

Nobody charges at 1 euro per kWh

Showroom7561,

how is that even possible?

Several reasons I can think of.

  • the lab tests are highly flawed.
  • the marketing is downright misleading.
  • people aren’t charging them.
  • people are using them in ways that don’t take advantage of the battery.

Hybrids are really only “green” when you use them for very short trips at low speed. In that context, any other form of transportation will be better, in my opinion.

ByGourou,

Yes, I think EVs in general (and especially hybrids) are a way to justify not investing in alternative modes of transportation for cities.

As for users you feel good about being “clean”, but in reality you are still polluting 10x as much as with public transportation.

Bytemeister,

PHEVs should be able to charge off of regenerative braking. You don’t need to plug them in to get benefits from the hybrid system. The stated fuel economy for the vehicles assumes that there will be a certain amount of electric-only travel. The article doesn’t say it, but most PHEVs advertise that you can use the battery for most of your day to day travel, and only use the ICE when you are making longer trips. So the takeaway from this article shoud not be “hybrids are bad, just keep making gas cars” but instead should be “testing and assumptions about the fuel use of these vehicles needs to be changed to more accurately reflect reality.”

hobovision,

Plug in hybrids usually do worse in mpg when in hybrid mode compared to standard hybrids, so if someone buys a plug in but doesn’t charge it, it’s actually worse than buying a standard hybrid. Regen braking is awesome but it won’t charge a plug in’s battery. The energy you get from braking 45-0mph would likely only get you back up to 15 to 30mph due to all the efficiency losses, plus you still need more energy to maintain speed.

Bytemeister,

As long as the system offsets it’s additional mass, it is a net benefit to the total economy of the car. Consider that an equally sized ICE vehicle loses 100% of that braking energy, and still has to accelerate that same 15-30 mph. You’re also leaving out that electric motors are much more efficient at accelerating a vehicle at low speeds than an ICE.

hobovision,

I’m just comparing a plug in that never gets charged to a standard hybrid. If you aren’t going to charge it regularly, you’re better off with a non-plug-in. Both are better than a non-hybrid, but if only the last 5% of battery capacity is being used that all the resources that go into the other 95% of the battery are wasted.

Bytemeister,

Makes sense to me. Not much point in hauling around more battery than you are going to use.

And that’s just tail-pipe emissions. PHEVs have much greater production emissions due to their batteries too.

hemko,

Because you buy one thinking you’d charge it more often. Maybe it’s slower to charge at home than you anticipated, or maybe it’s just more convenient to go to closest gas station than charging station - also WAY faster.

It’s like when you buy a box of chocolate thinking you’d just eat few pieces

BastingChemina,

I don’t think it make sense to go to a charging station to charge a PHEV with a 30-80km range.

It’s like going to the gas station to only put 3 liters in the tank.

hemko,

Yeah maybe not, unless if you can go shop or something while the car is charging

DacoTaco,
@DacoTaco@lemmy.world avatar

Just my personal 2 cents of owning a plug in hybrid : i sometimes drive with an empty battery because the range is 50km max, and my landlord refuses to allow me to install the infrastructure to charge at home, even if i’d pay 50% of the costs. There are also people parking in electric parking spots without charging OR being an electric car, denying me of charging publically. Its a whole mess…

That said, 40% of all km i drive are full electric.

Wooster,
@Wooster@startrek.website avatar

I feel like this is a large portion of the missing puzzle pieces. The difference between real world and advertised ICE stats are somewhat padded, but not significantly. You’d expect the hybrids to have a similar degree of discrepancy, but it’s wildly out of range of expectations. It may simply be that the manufacturers are giving idealized stats, since while testing they would have access to their personal charger in a laboratory environment. But in the real world, owners cannot guarantee working/accessable chargers or even that they can charge at home, which would dramatically impact the results of this study.

Or at least, I’d assume that’s the case in the US. I don’t know what EU’s charging infrastructure is like, where the study was preformed.

DacoTaco,
@DacoTaco@lemmy.world avatar

At least in my country public charging is popping up everywhere, but slowly. Not enough resources is poured into it because they think charging is not a thing yet. Thats bullshit ofc, and there is a reason i have my hybrid car. Also, you can charge at home from a regular power plug, and hybrid cars shouldnt need more than that to charge overnight or over 5h time. However, if you live in an apartment like me, you are royally screwed if the owner doesnt comply. Same with solar panels, but thats a different discussion for a different time haha

Forbo,
@Forbo@lemmy.ml avatar

Last place I was at completely screwed me over when it came to charging my electric car. I was leasing a Leaf and had been running it entirely off of the 120 charger. Lived at this place for a year and had no problem. Then someone on their HOA got a wild hair up their ass and said I couldn’t do that any more. They began by making up bullshit excuses, trying to say that it was a hazard to the landscapers. Except my roommate was the landscaper, and he didn’t give a shit. Blatant fucking lie from the HOA. Then they tried to pivot and say it was the insurance company that was prohibiting it. I offered multiple solutions including expanding the electrical for the covered parking, running power to the curb, or even getting an entirely new line run from the city. Emailed all this to them and hear fuck all for eight months. Then they send me a registered letter with a cease and desist. Had to early terminate the lease on my car.

Landlords and HOAs are some of the biggest inhibitors of EV adoption, and they can all go fuck themselves.

Be careful, not all landlords are pieces of shit. If i was one i’d do it, and im sure im not alone :)

cynar,

I’m guessing a lot of people don’t use them optimally. They used them how they originally used a ICE car. Unfortunately, that means they are lugging a large battery around for no significant reason.

I would also query how the hybrids are being designed however. There should still be a saving due to efficiency gains, since the engine can run at optimal RPM most of the time. The values scream that the manufacturers have over optimised for performance, rather than efficiency.

poVoq,
@poVoq@slrpnk.net avatar

Looking at the above data, these hybrids do reduce fuel consumption. About as much as you would expect from a non-plugin hybrid.

It is rather that the WLTP figure vastly underestimates the fuel consumption.

Monument,

There are a lot of possible avenues to cheat.
Obviously, every local law will be different, and What I’m saying below may not apply to certain areas. If auto manufactures are allowed to use labs of their choice for emissions testing, they may be able to engage in lab shopping to find a lab that will give them more favorable test results. If auto makers are required to use a government laboratory, it’s possible that in the process of developing the laws for testing, they’ve managed to work with lawmakers or regulators to ensure the tests are conducted in such a way that they get more favorable results than they would see in a real world scenario.

words_number,

In germany we had subsidies for hybrid company cars, so companies bought hybrids. But: If employees would charge these in their home garage, they would pay for the electricity. If they get gas, the company pays. So they are practically just regular cars with a ton (probably literally) of extra weight. Unfortunately there’s barely a single law related to cars in germany that makes any sense (apart from just randomly gifting tax payer money to car companies). It’s like gun laws in the US. The area-wide corruption is immense.

vividspecter,

Seems to be a repeat of the misleading (and outright cheating) scam that diesel emissions turned out to be, although presumably not quite as egregious as what VW did. Although perhaps part of the hybrid problem is that people aren’t actually charging them electrically most of the time, but that is also why hybrids are such a pointless half measure (even more than electric cars are a half measure compared to reducing car dependency).

Bytemeister,

You don’t have to charge a hybrid to get the benefits of the electric motor. It can charge from regenerative braking. That being said, plugging in a PHEV will maximize the benefits of the system vs relying on regenerative braking alone.

bobburger,

EVs only recover about 90% of the energy used I'm braking with regenerative braking. That means they don't even recover all of the energy needed to slow the car down, which certainly not enough to get the car back up to it's previous speed.

All this to say:

Regenerative braking doesn’t add significant miles to your driving range.

So relying solely on regenerative braking isn't going to have any meaningful impact on driving range.

Source

Bytemeister,

I think you should re-read your source. as it says this…

These small boosts in battery range can accumulate and improve efficiency over time when used regularly.

And your quote is out of context.

Regenerative braking doesn’t add significant miles to your driving range. Still, those gains in recaptured energy can really add up when used liberally and regularly.

Consider that most fuel economy is lost when the car is accelerating, having a system that captures 90% of the heat every lost to braking, which can then be used to get the car moving again, would be a huge benefit. That’s why regenerative braking can’t extend range, it instead reduces the impact stopping and starting have on the range of the vehicle.

bobburger,

You aren't getting the full benefits of a plugin hybrid electric motor if you're relying on regenerative braking. My source clearly explains this.

You get small efficiency gains that add up over time, but you certainly aren't seeing a meaningful extension in range over a single trip, and you certainly aren't seeing the benefits of a plug in electric motor if you rely on regenerative braking. In fact, this was one of the main points made in the OP; phev drivers rely on the ICE and thus don't achieve the emissions benefits that should come with a phev.

Bytemeister, (edited )

phev drivers rely on the ICE and thus don’t achieve the emissions benefits that should come with a phev.

This is true, but the assumption that this means that Hybrids are less efficient than their ICE-only counterparts and have detrimental effects on CO2 emissions is not. The article fails to put into plain numbers the expected CO2 emissions of each vehicle type, and their actual CO2 emissions. A lot of those PHEVs are advertised as having 0 emissions most of the time because you can use the electric only option. Even if people don’t take advantage of that by plugging in the vehicle, the hybrid system is still more efficient (except for some extreme long distance, non-stop scenarios) than a comparable ICE only car. The article does not tell us that hybrids are less efficient than ICE only cars, it tells us that our current methods for testing, advertising and accounting for C02 emissions for PHEVs are not matching real world data. This isn’t actually a new problem, discrepancies with lab data and real world driving data have existed ever since we started testing the fuel economy of cars.

Wooster,
@Wooster@startrek.website avatar

TBH, the most astonishing reveal from the study for me was that Hybrid owners weren’t charging their vehicles. Unfortunately, the why isn’t covered in the study since it seems to just be hard math and statistical analysis.

Are they just not plugging in at night?

Too frustrated with the battery draining too quickly?

Driving too far for the battery to meaningfully contribute between charges?

Is the extra hardware mass making the ICE that much less efficient?

Laziness from having to fill both the battery and the gas tank?

Pringles,

A lot of plug-in hybrid owners took the state support to buy an ICE with a smaller gas tank. And it also can drive electric, but nobody does that.

Semi_Hemi_Demigod,
@Semi_Hemi_Demigod@lemmy.world avatar

Considering the stories I’ve heard from mechanics about people having their car towed in because they ran out of gas I think people don’t realize they need to plug in their plug in hybrid.

poVoq, (edited )
@poVoq@slrpnk.net avatar

Plug-in hybrids are relatively new. At least in Europe most newly purchased cars are leasing and company provided cars. These companies probably thought it would be nice green-washing to buy hybrids. They probably also do not have sufficient charging infrastructure at their parking-lots and do not refund their employees for the electricity costs when they charge at home (or rather it is too bureaucratic for the employees to bother with asking for a refund). Which results that these cars are mostly used the same way as regular non-plugin hybrids, which only the relatively modest fuel savings these provide.

cron,

I think this is the real question. From the stats you posted, I’d say that at most 10% of Plugin hybrid owners charge their vehicles.

Which is such a waste of ressources. Why does someone buy a car with 10 kWh battery and never even use it (beyond what the car charges itself)?

sonori,

Especially given how much more expensive they are than conventional hybrids and the hoops you have to jump through to even grt one in my family’s experience.

The small battery capacity they have also means that any household outlet will charge them fine, so it would be really interesting to see why people are going through all the extra effort to buy one and then not use it.
