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.

Yes.

Certainly not the case for hybrids like Priuses. The battery system lasts 10-15 years and 150k-200k miles. Any ICE car on the market now should be expected to last a lot longer than that; I drive cars that are 25+ years old and really don't need much significant in the way of repairs.

As a data point: I’m at year 8 of Model X 100kWh with basically 0% capacity loss. If it exists at all, it’s less than 1-2%, so less than what I can reasonably measure with just the odometer and battery indicator.

Nissan Leaf gave BEV a bad name because it had much worse battery tech. Battery longevity is not a problem for modern, or even decade old cars.

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.

Still happening.

https://news.usps.com/2025/12/01/usps-is-delivering-its-new-...

> The Postal Service’s $9.6 billion upgrade of its delivery fleet is proceeding apace.

The organization plans to roll out 106,000 new vehicles by 2028, including 45,000 battery-electric next-generation delivery vehicles and 21,000 commercial-off-the-shelf battery-electric vehicles.

> Additionally, USPS is upgrading infrastructure at its facilities with the addition of charging stations for the zero-emission electric vehicles, of which over 14,000 have already been purchased.

> So far, more than 35,000 new vehicles are on the road.

> “The new fleet rollout is proceeding well, aligned with our plan,” said Justin Glass, the Postal Service’s fleet management senior director.

(USPS spends ~$500M/year for fossil fuels, so it’s a no brainer to electrify)

Wow, a small glimmer of good news. I almost want to hide this comment over fear of drawing attention to this thing that got away from the powers that be.

"But Trump and the Postmaster General cancelled that and went to use gas guzzlers instead. I wonder how that is working out now."

What makes you say that? The biggest impediment to the rollout was that the company that was supposed to build them repeatedly failed to do so, and finally had their contract pulled in 2021 and it was given to a defence contractor who seems to be on track to actually deliver the things.

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!"
trollbridge•6m ago
The "get rid of a working car" is particularly suspect, and reminds me of the "cash for clunkers" scheme which was basically a giant sop to the auto industry. Why not just have EVs replace ICE vehicles when they break down and aren't worth repairing?
