    • Battery warranty: 8 year, 100,000 mile (120,000 mile with Long Range Battery)
    Press Kit | Tesla Canada

    No mention of drive units, so they must fall under the 4/50k warranty. I am guessing this is a cost cutting measure, but it also might speak to their confidence on battery longevity.

    I know battery replacements are not unheard of for S's and it will be interesting to see how that trend plays out as the cars start getting older than 8 years.

    I think it's just a matter of having 500,000 cars on the road, potentially millions soon, versus 200,000 high end cars we have now. From a business standpoint, even if you're very confident in your technology, it just doesn't make sense to bet the farm when nobody else in the industry comes close to that kind of coverage and you've already proven your technology as being superior. As the owner of an older S (I can't believe we can say that) I'm sure you'd be able to attest to it's impressive battery degradation. I know my A-pack 2013 charged to 257 miles with 47,000 miles on it and that was low for cars with similar miles. That represents 3% degradation on a 4 year old car with the first generation battery pack. Impressive by anyone's standards, especially compared to cars like the Leaf.

    I think the drive units reliability is the bigger concern here.

    Elon Musk: "If we truly believe that electric motors are fundamentally more reliable than gasoline engines, with far fewer moving parts and no oily residue or combustion byproducts to gum up the works, then our warranty policy should reflect that."

    While the announced battery warranty surely limits Tesla's exposure, it does not really instill confidence based off all the model S data. It tells me that either the new higher energy density cells are worse, long term or they don't know. Either way, I am now more concerned about the future costs of a LR battery replacement at 150k miles than before :(

    Agreed.

    Many non-luxury automakers include a 5 year/60K powertrain warranty. Many luxury brands add on a year and 10K miles to that vs. their non-luxury brand. Warranty and Roadside Assistance Coverage -- Edmunds Auto Warranty Tips has a table.

    It would be nice to up the warranty a little more, even if it's not on par with S/X.

    Either that or Tesla thinks people are going to take less good care of the battery in a $35k car than they would in a $100k car.

    You don't need to "take good care" of S or X battery. Only thing to do, is not to charge it to 100% if not necessary.

    I think that was more or less the point. Out of all the ill-informed m3 users (the mass market), I'd assume a fair amount of people would charge to 100% daily. Gotta have the car last all day, right?

    And do shallow charges - which is very important to Lithium Ion longevity. A lot of us try to remain in the 40% to 70% range for daily driving.

    Can't imagine most people doing that with a Model 3. For starters - more people will own it who don't have a home charging spot and they will deep charge every few days instead.

    Regarding battery warranty, that is not relevant, because Tesla battery warranty doesn't cover normal range loss.

    I'm rather sure, car will give a warning if you do that. At least S and X give, I don't think 3 is different.

    OOC, what's optimal for battery lifespan? My experience with consumer-grade li-ion cells is that max lifespan is when you hold your discharges to something like the 40-70% charge range (for a 30% discharge). That is, keep the average a bit over 50%.
