Electric motors can last a really long time, assuming no defects, they should outlast the battery by a Longshot.

That leaves the battery, and an LFP battery should also last a hell of a long time, probably a decent way into a million km before you have degraded to about 80%.

If you got those key items lasting, then it just depends on how well the rest of the car holds up, but replacing small parts while the motors and battery works is probably always going to be more cost effective.

The problem is the battery is a wildcard still.

We know how long those LFP batteries should last in a car, but they're also pretty are in cars and we don't have that real world data yet.

I also fear that OEMs will still gouge us on replacement batteries 15 - 20 years from now when costs are even lower and replacing the battery shouldn't be so expensive.

There's an old expression: Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands.

If a car has a warranty of 10 years, it will last 11 years.

If the government regulates them*

I think people need to start being educated about how their climate influences how they can use the electric car. Many people know if they live by the sea or where roads are salted that corrosion is an issue. But people might not be aware that with some EVs, they should leave it plugged in if they're in an extreme climate, so the car can air condition or heat the battery. I caused some battery degradation to my Volt because I wasn't able to leave it plugged in living in Tucson.

Obviously they wont "let" them. Why would they ever do that? They have to be made to do it. But I hope i'm wrong, we will see.

Which was also true of ICE cars. The Model T Ford had a major design flaw: everyone could work on it easily, parts were plentiful, and there was no reason to buy a replacement once you had it. In fact, there's enough of them still running, with an associated parts market, that you could still daily one if you wanted to.

“Unlike gas-powered engines—which are made up of thousands of parts that shift against one other—a typical EV has only a few dozen moving parts. That means lessdamage and maintenance, making it easier and cheaper to keep a car on the road well past the approximately 200,000-mile average lifespan of a gas-powered vehicle. And EVs are only getting better. “There are certain technologies that are coming down the pipeline that will get us toward that million-mile EV,” Scott Moura, a civil and environmental engineer at UC Berkeley, told me. That many miles would cover the average American driver for 74 years. The first EV you buy could be the last car you ever need to purchase.“

No way a car would last me and my family 74 years. First year I owned my car I put on almost 35k. Was driving 100 miles back and forth to work at that time. We typically take a road trip from colorado to near Vermont every year for a vacation.

A lot of midwesterns will drive 14 hours to get some where

Sure, there's always going to be outliers. Most people live and work in the same metropolitan area though - they're not driving 50,000km+ a year. Besides, having a vehicle with 5 times the effective lifetime is going to be a big win regardless of how much you drive it.

At best case 60 miles an hour... Your commute was more than 90 mins? Ugh. That's awful.

You weren't clear if that was round trip or not, so possibly more than 180 mins? How did you find time to sleep!?

It would be wonder if they last forever and easly could be repaired. Making it better to keep the car then buy a new one. It just need to be upgradedable to the latest standards that might be more safe, efficient and agree with current law.

But I am pretty that would never exist - too hard.

Wear and tear doesn't kill a car; rust does.

[–] [email protected] 6 points 5 months ago (3 children)

Back in the day you could buy whole (but small) parts, cut away the rusy one and solder in the new one (paint with anti rust paint). Did it on my cheap ass volvo 142 :-)

Maybe you can't do that any more because of complex crumple zones, but I bet we can do better. A car shouldn't just have a life span of 6-10 years.

A car shouldn't just have a life span of 6-10 years.

They don't.

My current daily driver is 18 years old. I expect at least another 10 barring an accident, maybe 30 more years as a spare vehicle. It got a new transmission at 200,000 miles. Engine seems like it'll make it to at least 400k. A replacement is $1500, far less than a new car.

Most cars in my family (approximately 30 cars) are between ten and thirty years old.

I've had 3 cars since 1996, all bought used, and I traveled for work with one. One car I sold to a family member, and it's still being driven.

It's people that choose to not drive cars this long.
