For me the most interesting part of this and other threads relating to battery pack is this: the battery pack is replaceable, the battery pack determines the charging rate, the battery pack also determines overall longevity, the S2 battery pack (per Vger's nomenclature) is being limited for a reason that I'm interpreting as being related to cooling issues. At 90kW charging I've felt the heat pour off the front wheel wells as the fans kicked to full. The S3 packs are prolly made of cells that are better at scrubbing heat, possibly the packs themselves are better optimized for the task as well. I'm making an overall guess, but I'd suspect you could measure that by taking an S3 P85 to "track day" and it'll go faster for longer than an S2 P85.
Follow up questions relate to battery longevity, but I'm guessing the relative limits placed on supercharging keeps the battery longevity roughly equivalent. The issues aren't really around normal driving, they are around the limits.
Regarding the importance of the packs being replaceable -- I'm looking forward to plugging in a 500 mile pack in 10 years but by the same token I don't think I'll need to because the charging infrastructure will be so much better. :smile:
