Battery Warranty on the Tesla Model X (85 kWh): "8 years, unlimited miles". And the "Battery Replacement Option" after 8 years.

Battery Warranty on the Tesla Model X (85 kWh): "8 years, unlimited miles". And the "Battery Replacement Option" after 8 years.

Paul does business in many countries in Europe (UK, Portugal, Spain, France, Belgium, The Netherlands, Germany, Switzerland, Italy, Denmark, Norway, Sweden, Finland, Poland, and Russia). Paul's company has 80 offices in most of the large cities in all these countries. Therefore, Paul travels every day with his brand new Mercedes Benz E Class, which is driven by his driver. They drive easily 120,000 km per year, and that means that they both spend a lot of their time on the road every day.

Paul agrees with the vision of Elon Musk regarding sustainable energy. Paul desides to buy the Tesla Signature Performance Model X (with the 85 kWh battery pack, AWD, etc). Paul also desides to have the "Battery Replacement Option" (let's suppose that option will be available for the Tesla Model X just like it will be available for the Tesla Model S). Paul wants his Tesla Model X to be delivered in January 2015 (suppose that Tesla Motors have confirmed to him that this will be possible). Till then he wants to be driven in his brand new Mercedes Benz E Class.

Tesla Motors will have established a number of Superchargers in Europe by January 2015. Not all, but enough for Paul and his driver to make long distance driving possible. So, as from the beginning of 2015, Paul and his driver can charge the Tesla Model X at the several Superchargers, and that's what they will do.

Suppose, that after 4 years (January 2019), they will have driven in total a bit more than 500,000 km in the Tesla Model X. And suppose that they will have charged the Tesla Model X at a Supercharger location about every day, and sometimes even twice per day, say 400 times per year. That would mean that they will have charged the Tesla Model X 1600 times at a Supercharger location in 4 years time. And after every year they notice that there is a clear difference in the number of km they can drive on a full charge. After 4 years they conclude that the number of km they can drive with the Tesla Model X is less than half as much km they could drive when the Tesla Model X was brand new delivered in January 2015. This is yet a hypothetical situation, but it is possible that this could just turn out to be a true situation, because of the use of Superchargers to charge the battery of the Tesla Model X 400 times per year, and because of the high number of km that they will have driven in the Tesla Model X.

Now, my questions are:

Question no. 1. "Will Tesla Motors replace the 85 kWh battery pack of the Tesla Model X, as a result of the Battery Warranty (8 years, unlimited miles) in January 2019"?

Suppose Tesla Motors have replaced the 85 kWh battery pack, and the following 4 years they do the same (drive 500,000 km in 4 years, and charge at Supercharger locations 400 times per year).

Question no. 2. "And will Paul be able to have the brand new 85 kWh battery pack replaced again in 2023 (so, again after four years) as a result of the "Battery Replacement Option" that he chose for when buying the Tesla Model X"?

I think you're more likely to see 225.

I'll tell you what... compare actuals about 8-10 years from now! :)

After 8-10 years 225 miles on a full charge would be OK.
