With EVs, we might get some battery packs and drive trains actually lasting this long. Maybe not with nmc batteries. But some lfp batteries seem to have enough charge cycles on paper that they really could last that long. 5000 charge cycles at 300 miles per charge adds up to about 1.5M miles. Of course lots of other things might fail. But at least electrical motors are known to be pretty durable. That's not a common failure point on EVs as far as I know. But there's plenty of other stuff in EVs (electronics, cooling systems, suspension, etc.) that can break.

Of course, it will be a while before we'll see EVs that have driven that far as those type of batteries have only been on the market for a few years and even with 100K miles driven per year (which is a lot), it would take 12 years to get to 1.2M. This Toyota took quite a few decades to get there.

According to the article, this car actually wasn't particularly durable (the words 'rust buckets' were used). But if you just keep patching it up, of course it will run fine. And greasing up all the bits that would normally rust seems smart as well.

Because if you get chain timing issues on a 2010 BMW diesel, you ain't repairing that, it's more expensive than a new car.

https://en.wikipedia.org/wiki/Irv_Gordon had a Volvo with over 3.25 million miles (5.2Tm), although it's also had 3 engine rebuilds.

But they aren’t, not even close. Oil is massively subisidised by the military before the environmental costs. Brake particulates and tyres don’t cover the cost of microplastics and lung damage, heavy cars don’t pay anywhere near the damage they cause to the roads and bridges etc.

Due to this you can argue pretty much whatever you want by ignoring certain costs depending what you want to come out with.

My petrol car is 20 years old, it’s done 70,000 miles, it weighs about 1,000kg and burns through 300 litres of unleaded each year to do the 3,000 miles I do in it.

I suspect scrapping and replacing this with even a small electric car would not be globally environmentally worthwhile. There may be improvements to local air quality assuming regenerative breaking etc, that may be offset by increased tyre and road wear though, even ignoring the impact of the co2 to generate the 80kWh a year it would require.

As long as some enterprising pirate (probably a shady Russian forum) keeps hold of all the model-specific software.
