Hello everyone

,
I'am about to purchase the Panamera S e-hybrid.
But in advance I would like to know if there is any battery performance limit (e.g. 50% capacity or 5 miles range) defining the battery as defect.
I know that Porsche delivers the Panamera S e-hybrid with a battery warranty of 6 years and an optimal driving range of 20 miles.
But does anybody know if there is an exact performance level of the battery at which Porsche considers the battery as defect and changes the battery for warranty claim?
I am thankful for every information!
Cheers Marc
