Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
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. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating 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 10/19
-
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.

Battery prices are now close to $100 per kWh and are predicted to keep dropping.
https://www.goldmansachs.com/intelligence/pages/electric-vehicle-battery-prices-falling.html
That's $7k for the 60-70kWh battery we see in lots of cars. That's offset against an engine that has multiple hundreds of moving parts, also worth several thousand.
The engine has hundreds of parts but really only a couple of them are moving. That's the beauty of electric motors.
They're comparing against the price of an ICE engine and the fact that they don't contain one to offset the cost.
But they do have an expensive electric motor instead of the ICE, plus an expensive battery.
Electric motors are substantially cheaper (and simpler, and lighter) than internal combustion. Hell, the typical ICE has two electric motors already in it! (starter, alternator)
Not really. There is a lot of metal - wires - in the electric motor. Retail prices on motors is a lot higher than the retail price on an ICE. https://www.grainger.com/product/WEG-IEEE-841-Motor-250-HP-15G092 is a 250 horse power motor for $30k. https://www.jegs.com/i/Chevrolet-Performance/809/19435110/10002/-1 is a 500 horsepower ICE (I think this is new, but the site also sells rebuilt engines) for $7k.
Of course with motors there are a number of different ways to built them at different costs. However they are not cheaper than an ICE and we shouldn't expect that they would be as there is a lot of metal in a motor.
Sure, but they are small, neither one is capable of moving your car down the road at full speed (the starter might do it for 10 seconds but then it will overheat)
You have whole (electric) cars for 30k, that price is laughable. Here you have 220kw (300HP) motor, inverter and differential for 3.5k euros: https://eveurope.eu/en/product/tesla-model-s-drive-train-220-kw-2/
The price difference between a single motor VS dual motor on most cars it's also around 5k, including extra cables, installation, etc.
I can't find any source for the type of motor used in electric cars - which presumably will be made in larger quantities bringing costs down.
A motor basically consists of copper wire and magnets neither of which are expensive materials.
An engine mostly consists of iron and aluminum which is much cheaper than copper. (cars makers are looking at if they can use aluminum wires in their motors - I'm not sure on status of that)
Yes with hundreds or thousands of parts that all need to be cast or machined to tolerances as tight as a few thousandths of an inch. Electric motors just need copper wire wrapped around in circles and a shaft with magnets attached to it. It's very basic. I get that you want to be right but you're not going to win the argument that electric motors are more expensive or costly to produce than an internal combustion engine.
An engine is not thousands of dollars. They mass produce them and so the incremental cost for each one is less than $100 each. There is a lot of engineering costs in an engine, and the cost to setup mass production is high, but that is amortized over all the cars they put that engine in. (there is a reason auto maters only have a few engines that they put in everything)
A battery is $7000, but the raw materials and labor to make it are a large part of that price (I don't have insight on what the price is) Of course auto makers know they need a lot of batteries and so are working on automation to bring the per battery cost down.
An engine would scrap for more than $100 you’ll have to cite that figure to make it believable.
Last I checked the whole car scrapped for $250, and there is a lot more metal in the rest of the car (transmission, drive train..) than the engine.
Engines are worth more than $100 if they are rebuild-able. However the incremental cost to the automaker is less than $100. Remember, incremental cost does not include the cost of engineering, setting up the assembly line, or profit margin (which are all very expensive and raise the actual cost) - just the raw materials and labor to run the line.
No citations and more outlandish claims. So I’ll put a little math here. From the first google results aluminum scraps around $0.44/lb and a smaller engine block is about 300lb which comes out to $132, not including heads manifolds, pistons etc.
Lmao if you can build a reliable car engine for $100 I'll give you a billion dollars for a car startup that will outcompete everyone else.
You fail to understand the difference between incremental costs and full costs. A modern car engine can be under $100 each for materials and assembly labor. However that does not count the costs of engineering, or building the assembly line, much less profit margin. Those costs are much higher in an EV.
