How long do electric car batteries last?

The Model 3 Performance is so much quicker than the vast majority of vehicles on the road that I doubt you'll find yourself using the full acceleration very often. It's literally supercar fast. I haven't driven the refresh, but even the prior model was uncomfortably fast and the new one is even quicker. My wife's I-Pace ran did 60 in around 4.4 seconds and the 1/4 mile in 12.6. You couldn't punch it without warning passengers. The M3P is under 3s to 60 and 11s 1/4 mile. That's stupid quick for a daily driver.
If I show people the M3P acceleration I tell them to brace their heads against the headrest and grab the seat or whatever.
Otherwise it will snap your head back and hurt. Don't ask me how I know; wifey showed me that day we got the car. Seriously.

The 1st M3P pulled hard to about 90 MPH, but that was about it. The '24 refresh is another story; it pulls hard to at least 130. Literally 10 second 60-130. That's fast.

 
My guess is, you will come to love your M3P. How ya gonna charge?
One thing; tires don't last.

**** I am hooked! Picked up my car Wed. Enjoyed driving around car buddies that night. Did a supercharger test Friday before road trip to visit family. A 20min supercharger to get me home to have some extra juice….used it to shame a LT1 Camaro that gave up right away.

The power on demand is like cheating. I remember the days in the 300ZXTT and my routine. Turn off radio, kill AC, turn on vent, tap high boost on boost controller, choose gear and go. Now it’s 2 clicks to make sure you are in Insane mode…. punch it. LOL

I will say FSD is nuts, freaking psychopath on busy highway traffic. It’ll change lanes all over without giving it anything so it’s over two then back…couldn’t do that stupid ****. Just drive pass traffic because people like to bundle together for some reason then it’s find. Or chill but that is hard for me….I enjoy moving. But I also noticed on tollway at 85 that it seems to spike throttle and release it tons a times a second. You can see the power bar just jumping up and down like crazy. Thought it was wind so I tried myself….kept it nice and smooth with about a 1mph fluctuation. Weird how it can’t be smooth or I have a really sensitive ass that can feel that. Along with the on center wondering. Had steering in heavy and standard but both felt the same. Again maybe I’m sensitive but don’t feel that in both the 2000 S2000 and 2006 Civic Si EPS. Curious but I’m going to look into the suspension, curious if any caster can be added to help. Or maybe she has too much toe out? Anyone else notice these things?
 
There is a setting where it will try to keep the car centered in the lane. Make sure that is tuned off. I'm not talking about autopilot. I don't remember what it's called.
If it is turned on, it will feel like the wind is buffeting you.

Good point. I remember the setting but think I left it on. Will have to test. Thanks for the tip.

I haven't seen that setting, but I will say the wandering does come up in heavy wind trying to compensate for the wind. It happens driving normally in any car, but it's different when you're compensating yourself as a driver.
 
When I got my model Y in January of 2025 the steering driving down the interstate would wander between the lines. I thought there was a problem with the alignment and was thinking I needed to take the car to the service center to be checked out. Then while scrolling through the touch screen I found a button that said something to the effect of "assist keeping the car between the lines". I disabled that and the car has been great since that time.

But, now I'm feeling both baffled and foolish. I just went out to the car and looked for that button. The closest thing I found was under auto pilot, called lane departure. Labeled "Assist". And it is on. I believe this is what I turned off last year. How it got turned on and why I no longer have the wandering on the interstate is a mystery to me.
 
Good tests, then real use, should make the tests almost seem like sand -bagging. Silly analogy, but rigorous testing should be the norm. Anyway, good easy reading article.
The comments in the article regarding discharge depth mirror the comments I saw made by Jeff Dan of Dalhousie University in a recent Youtube video. To wit, 80 -> 50 -> 80 is better than 80 -> 20 -> 80 because it reduces the expansion and contraction of the cell internals.

Sure, there's plenty of bias.... From skeptics who hate the idea of hybrids or full-on EVs. You know, the ones that insist they ALL fail in less than 10 years, cost 4x the value of the car for a battery replacement, and so on. All false, but spread as if fact.

My wife has a Toyota hybrid and Toyota warranties everything in the hybrid system, including the main batteries, for 10 years or 150k miles. Seems to me they have confidence. I thought I read that even Honda is partnering with Toyota for their batteries because of how well theirs are.

I am a fan of hybrids and I'd love to buy one as my next vehicle. I've been looking and I'm not ready for the add'l $$ premium though. I'm not ready for a full-on EV yet myself, though it would work for me. For longer trips, we would almost always take my wife's SUV anyway.
I like the idea of hybrids but I find myself questioning potential battery issues. How does the warranty work on batteries? Does the battery have to completely fail to be covered because as we know, they can continue to hold "some" charge for a long time. Let's say in 8 or 9 years capacity is 50% or lower would is that low enough to trigger warranty coverage? Are there magic numbers that have to be met to instigate warranty replacement/coverage? A regular hybrid has pretty limited range as it is. I think I'd be pretty upset if they told me that I would have to accept even less range waiting for an arbitrary threshold to be met for warranty coverage.
 
You're confusing hybrids with EVs. A hybrid has NO range restriction other than running out of gas.
My SIL has a Rav4. I encouraged her to look at a hybrid because I was familiar with her driving habits. She can drive to her daughters house about two miles away at residential speeds mostly on battery power. She does this every school day to pick up her grandkids at the school bus stop. She's absolutely giddy about her fuel savings. The battery power is also a major factor in getting the vehicle moving which further accounts for its efficiency. Losing the ability to do either pretty much defeats the purpose of a hybrid. If at some point the battery cannot retain an adequate charge doesn't that compromise a hybrid vehicle?

Hybrids will switch between (full) EV and gas mode as they need to. Yes, with some models you can keep it in EV mode quite a bit but it will switch to gas and recharge no matter what the driver does. Have her force EV mode (with the button) and see how far she can make it. It won't be far, in fact, I'll bet she can't make that 2-mile drive without a warning about the battery popping up. I tried this overseas with a Toyota Corolla hybrid and it was less than a mile before it warned about it.

I've always been curious about that. Thanks!
