Don't know of too many gas burners that would still be running after 400,000 miles on an engine. So all this talk about evs not having good resale value because of battery degradation ofter 100k needs to be put to rest. I only use the fast charger once every 6 months or so, the rest of the time I charge at home, which is like a trickle charger and doesn't harm the battery. So we'll see what happens when I reach 400,000 miles. If I live that long.

Where was this test done?  Every state/Providence has different weather.  In a perfect state it would not degrade the battery.  When you have 90 degree weather one minute and snow the next how does the battery hold up.

Your Chevy volt, and most EVs, have quite complex cooling systems for the entire battery system that work regardless of passenger cooling.

Different EVs have different charging curves. What would have been actually useful would have been to compare this high mileage model S with a much lower mileage model S of the same year and specs. It Could've proven how a high mileage battery Changes its charged curve and charging speeds.

Didn't need that because it had the baseline to compare to, and the range loss was so minimal (<10%) compared to the vast mileage(430K+), that any further comparison was unnecessary.   What will be interesting is to see more models with these 400K+ miles/kilometers tested to see how they fare, but I'm thinking they'll do even better the later the model year.

I think we're well beyond the myth that EVs won't outlive any ICE in terms of longevity, and the potential is there far less maintenance.  To replace a tranny on an ICE starts at ~$6K for the most reliable affordable cars released 8 years ago...

Now: to work on the skyrocketing insurance rates...

I too questioned the use of a completely different EV for this test.  It did however prove one thing.  The Model S with 430000 miles is still a capable vehicle.  Enough said

> Just like the battery lost some of its range, the car registered a slump when it comes to acceleration (still under 5 seconds)

It wasn't though, it was 5.5 seconds, which is not under 5 seconds and a whole 1.1 seconds off of its numbers at launch.  That's 25% longer than new, not some small change.
