Original title “The climate benefits of retiring a fully operational internal combustion engine vehicle” compressed to fit within title limits. A new lifecycle study in the journal Science concludes there are substantial climate benefits to swapping an internal combustion engine (ICE) vehicle for an electric vehicle (EV) even if the ICE or hybrid vehicle is brand new, if driven more than ~7,054 km/year (4,384 miles/year).

It looks like they have the BEV lasting just as long as ICE car without any battery replacement. Has it turned out that way? Seems like owning an electric car for 18 years really hasn’t been a thing since the model s was released in 2012, but is it projected to last that long.

The US Post Office was slated to use EVs as replacements for worn out mail delivery vehicles. For many areas, especially urban areas, those would have been perfect and cheaper in the long run. I know because I knew a lot of Mail cCarriers and I know how these are used. As a kid I was driven around a route one day with a relative. But Trump and the Postmaster General cancelled that and went to use gas guzzlers instead. I wonder how that is working out now.

Propaganda for "Scrap your old car now and buy new—now with AI driver spying features as mandated by Congress, and personal data sales to insurance companies!"

Can we not finally close all volcanos?

The fact of the matter is that the only thing that matters to most people is what makes economic sense to them. As for me, no way am I trading my 20 year old, fully paid for, cheap to insure, cheap to register ICE vehicle for a new EV with payments, higher insurance, and higher registration fees.

We replaced our 2010 Ford Transit (diesel) with a 2022 Ssangyong (LDV) eDeliver 9 (battery electric), and one of the benefits I didn’t expect was just how much quieter it is in the cab - a conversation with my partner when we’re driving is much easier/more pleasant. (It’s not due to better insulation - both these vehicles are basically steel frames on wheels) - I don’t see this mentioned much in articles comparing EVs and ICEVs.

I'd love a BEV but where do I charge it? If I use public chargers isn't that vastly more expensive?

There is an element I haven't seen in this conversation: as the number of combustion engine cars goes down the number of gas stations also goes down. At some point, combustion engine drivers will start feeling range anxiety. So when you get rid of your fossil-fuel-burner vehicle, you are pushing others to do so. The full calculus of CO2 emissions reduction should also include the reduction induced in others.

I would like to get rid of it in the next few years but all new cars have only touch screen and phone home. Are there "stupid" e-cars too? I don't need much.

Why not sell a fully operational car as a used car and buy a new electric vehicle? Then, when looking into all cars, the fleet will get one more electric vehicle, but at the same time fully operational cars are still used until the end.
