I think most of the numbers are making more and more sense to me. I have had my car for a few weeks and around 800 miles of drive. The computer is extrapolating around 260 miles of range with my standard battery. The information shows around 26-27 kWh per 100 miles which would seemingly mean around 300 miles of range. If you presume Porsche holds back around 10 kWh of the battery reserve (like they stated with the extended battery), the numbers almost work perfectly. Standard battery likely has around 70 kWh of usable battery yielding around 260 miles which is virtually identical to what I am seeing. Interesting.
