We all know that battery capacity decreases and the tires will probably wear out faster (if I keep pushing them) but what about:

1. Battery Power output
2. Electric motor power per watt
3. Electric motor max power
4. Regeneration efficiency
5. Charging rate

Feel free to add other subsystems that might age that I have missed.

There have been articles about higher mileage Tesla vehicles (one used as a taxi IIRC) — that have fared amazingly well. The most recent articles I’ve seen studied/published indicate a 1% range loss every 20k miles. That is to say that a 300 mile range Tesla will still have 240 miles of range at 400k miles. Most indications of other components is that they will have life spans in the 1 million+ miles of life. With little to no degradation.

Now I’ll admit I am not an electrical engineer, or an EV specialist by any means. But from what I have gleaned, the item(s) you mentioned will endure longer then the rest of the car. Sure like any car, bushings/rubber parts will need replaced, shocks/suspension, brakes, tires, the usual. But the drivetrain stuff should be pretty close to 99% capability, save for the battery, which even that as noted has a minimal loss.

PS: If the same battery life expectancy is applied to our ~200 miles of range, then at 200,000 miles (which is FAR longer than the average gas car’s life) would still have 180 miles of range (EPA rated) which is pretty darn impressive.

I'd be interested to know what the battery replacement/refurbishment costs would be down the road if the capacity loss was enough to be an annoyance.

In one of the early reviews of the XC40 Recharge (maybe it was on arstechnica?) I remember reading that Volvo had had a hands-on role in assembling the batteries from LG components. The advantage of their design was that if individual cells had gone bad, they could be replaced rather than having to swap out the whole assemblage. But I only remember reading that once and then never heard any more about it.

ETA: This is one of the articles I remember reading about the battery packs, but it's not the one that mentioned the possibility of replacing individual cells... still can't remember what source that came from.
