Abandons NEW combustion engine development. They’re still developing their existing combustion engine platforms further and aren’t giving up on ICE.

You making a lot of assumptions that arent born out by current experience. Its not uncommon for 100 year old cars to be registered and driven on public roads today. I personally have registered “daily drivers” from the 1970s and 80s. I actually rebuilt my 1972 motorcycle using factory parts from the dealership. As cars get rare they tend to increase in value, which also increases the return on effort/money put in to…
I have one, too. Not really as a daily driver, gas mileage just sucks. When the daily driver is about to be replaced one day, it will certainly be by an EV. I think that the main issue will be maintenance of ICEs in the future. Like try to find a garage that is able to tube carburators these days. It will be a while until we reach that point so.
You dont need top of the line $1700 Haltech elite 2500 or Link G4X FuryX if you arent seriously racing.

A hundred years after EV's become commonplace, our descendants will learn about ICE in history class. They will be told that their great great grandparents' generation dug holes thousands of feet deep in the desert and under the sea to extract the liquid fossilised remains of plants that lived on Earth hundreds of megaannums prior. They took these liquid fossils, refined them in factories, transported them all over t…
EVs are not going to eliminate the oil&gas industry. We still need it for aerospace, military, maritime, mining, construction, plastics, chemical feedstocks. Some of those use cases we may find alternatives for over the coming decades, but I reckon in 100 years the oil&gas industry will be still around. Very likely it will be smaller than it is now, but I very much doubt it will be gone completely.
The plans for the Euro 7 standard are “technically a huge challenge with at the same time little benefit for the environment”. “This places extreme restrictions on the internal combustion engine,” Duesmann said. If the Euro 7 standard has little benefit for the environment, it should be stricter, because the cities are full of toxic gases.
They’re saying it has little benefit for the environment and yet they’ve stopped developing new ICEs in favour of electric. Seems like it’s working to me
ICE’s have over a century of development behind them now. I’m not going to miss them, but I wonder if there’s a way to ‘archive’ this kind of specialist mechanical engineering knowledge. It may come in handy one day. It’s depressing to read about engineers having to go to the Smithsonian to study the lunar lander to relearn some of the innovations and improvisations made at the time.
They will mostly disappear from cars, and (more slowly) even trucks, but they are still going to be around for a lot longer in other applications – backup generators, heavy construction and mining equipment, the military, locomotives, smaller aircraft, ships and boats, etc.
We may well start to lose some knowledge about how to design ICEs optimised for specific use cases, we aren't anywhere near forgetting how to design ICEs in the general case.

You can DIY mod carb engine to EFI using plethora of cheap user programmable ECU modules and oem/salvage yard parts, its almost Lego at this point in time with everything understood and tons of documentation in the open. Throttle body, MAF, Lambda sensor, one fuel injector, fuel pressure reg, fuel pump, crankshaft position sensor, ECU, laptop to program and tune the ECU, all in all https://kjetkillers.pl/en_US/c/EFI-…

But they're still iterating on current ICE engines, which you could call development. And in that case they're still developing ICE technology. It sounds like the only thing they're claiming is they will not come up with completely new designs.
The old product will get big fixes and some minor performance improvements (basically maintenance mode), but all the real R&D is happening on the new product.

Technology knowledge is extremely ephemeral and easily lost once you stop using it because so much of it is "tacit knowledge" that is only preserved by active use and passed by mentorship/apprenticeship.
We've lost many technologies this way. In some cases like FOGBANK and the recent B2 bomber heat exchange system, there was enough incentive to reconstruct it from scratch at great cost. For most lost technologies, that incentive will never exist. If you are very, very lucky, some other country will maintain it by continuing to manufacture it.
This is a major reason why "bringing manufacturing back to the US" is so hard. We literally lack the technology/knowledge context as a society to do that most of the time. It's like pondering a semiconductor fab project in Chad or Sudan!
Otherwise it becomes like pyramids and monoliths that some "moderns" can't imagine came from anything other than space aliens! "They couldn't have made anything like that back then because we can't do it today."

I don’t remember the lunar lander, but I do recall reading how each rocket engine on the Saturn V was one of a kind, because the engineers had to assemble each one by hand, and each acted slightly differently. So there’s no way to reproduce a specific Saturn V engine now, but there also never was back when the Saturn V was still flying.
Would we do any differently today? I think we gravitated towards smaller and more numerous engines (that are easier to construct to the same exact copies), but nobody since has built anything remotely as large as the Rocketdyne F1.
Duplicating the F1 would involve technology and knowledge of individual engineers who are dead and corporations that no longer exist. The TACIT knowledge and technologies required to go with the blueprints died with them.
