Graph: battery capacity loss study of multiple Tesla Model S sedans

[MetroMPG]

This will appeal enormously to EV fans and data nerds:

Tesla Motors gives an 8 year infinite miles battery guarantee. However, it is still relevant for every Tesla driver to know what to expect of the degradation of the capacity over time, because it is equivalent to the range of your car. In the Netherlands, Merijn Coumans is updating on a regular basis, via the Dutch-Belgium Tesla Forum, a file of owners’ data. The most recent version of the results is displayed below.

That's actually NOT an all-that-bad looking curve for battery loss!

In fairness, infinity miles in 8 years would be faster than the speed of light. They should only guarantee a quadrillion miles.
