A community for discussing events around the World
Rule 1: posts have the following requirements:
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

People in this comment section are obtuse as fuck, I don't know if willingly or not.
Thanks for posting the study, they're completely missing the point, and it was an enlightening revelation to me
My 2003 petrol car gets 6 litres per 100km. Even if the PHEVs are running like a normal hybrid 100% of the time, that economy is trash.
My 2006 diesel swallows 5.1L/100km, and it fits 7 people inside. New cars are mastodontic for no fucking reason
The article is horribly unclear: it seems to say that PHEVs are no good, but "the main reason for the higher-than-stated fuel usage was ...that the PHEVs use two different modes, the electric engine and the combustion engine". Well, so do non-plugin hybrids. I doubt they're saying that plug-in hybrids are worse than non-plugin, but you might guess that from the title.
The article states that Porsche PHEVs used 7 liters per 100 miles (33.6mpg), but Kia/Toyota/Ford/Renault used "85% less" (1.05L/100k or 223mpg... maybe about right if driven 75% from plug-in energy).
Porsche mentioned "different usage patterns". I can buy that a typical Prius owner is plugging-in every night, filling low-rolling-resistance tires to 54psi and driving like grandma, and a typical Porsche owner... isn't. If you want apples-to-apples, then compare a gas Corolla vs a Prius vs a Plug-in Prius, where the cars are from the same city/suburb, and similar owners (e.g.: no ubers, no regional sales reps).
This "study" is evaluating real-world use of one class of vehicles, and not other vehicle types; then using the dismal ways some people drive to imply that this particular class of vehicles is the problem.
I think the point is that PHEVs do not achieve the real world emissions promised by the manufacturers, which would call into doubt reliance on them to save the climate as well as tax reliefs. Particularly, company cars are historically subsidized too much, and they get even more subsidies if they are hybrids, only to then never charge them.
So I own one of these vehicles and I was thinking there's no way this can be because I can see my fuel consumption and it is very low. But according to the article it varies greatly by model, and mine was mentioned as being on the low end.
For me at least, I can hear when the engine turns on and it does not do so until the battery range is used up, so there should be no fuel usage during short trips. It seems quite strange that some vehicles would work otherwise.
Until now it has been claimed by manufacturers that the vehicles used only a little or almost no fuel when in the electric mode.
I have a PHEV and the gas engine shuts off completely when in electric mode. I don't see how it could be using gas when it's not running. Are they confusing the hybrid mode with electric mode?
Misleading article. Someone reading this may think that a PHEV will have higher fuel consumption than claimed. When it reality it should be clarified that fuel efficiency is based on roughly 75% electric drive share.
I see the point where they should adjust that down based on real.world usage.
But... if you are expected to drive 75% electric based on battery range and your usage, you will hit the manufacturers claims, give or take
While most hybrids are said to use one to two litres of fuel per 100km, a study claims they need six litres on average
I can say from personal experience that my Chevy Volt gets around 40-60mpg when it kicks over to gas. That said, it rarely does, because my daily commute comfortably inside the battery's range.
Until now it has been claimed by manufacturers that the vehicles used only a little or almost no fuel when in the electric mode. The studies showed that this was not in fact the case.
Again, I've got a tank of fuel from... several months ago? Barely 7 gallons and it hasn't run out. Like, I almost never visit the gas station anymore. So, idk. Maybe the Volt was just built better.
You were charging it. The PHEV drivers are not charging at all, they were told the cars were self charging. Many use street parking and can't charge. They should be driving hybrids, not plugins they never plug in.
You have to work at a car service center to truly appreciate how stupid some people are, and they are not rare.
