I remember extensive discussions (last summer?) about Tesla's bending toward battery chemistry that puts emphasis on storage capacity rather than power output. My recollection is that there's a limit on that endeavor to achieve the performance goals (especially in the P85 and P85+). Assumptions 1. Gen 3 is 25% volume scale-down of Model S. 2. Gen 3 has similar (maybe identical?) Cd. 3. Weight scale-down is 25% or more. 4. Minimum range of 200 EPA 5-cycle. 5. Acceleration of 0-60mph comparable to Model S 60 kWh (5.9 sec). Questions A. Using what is publicly known or "comfortably assumed" as available to Tesla today at "production levels" and with "reasonable pricing", are there battery chemistries that satisfy all 5 assumptions at once? B. Does the battery volume and weight scale down similarly to 1 and 3, or disproportionately with the rest of the car? C. From production cost alone (not design, no software development, no assembly line retrofitting, etc.), how would such a vehicle compare cost-wise to Model S 60 kWh? I'm curious to see what "educated guessing" and "napkin calculations" conclude on this one.
