I am guessing that by the time the M3 is launched at least a P100D version of the S and X will be available (and recent reports suggest this may be coming sooner rather than later). If that's the case it seems likely the 3 will come in ~60kWh and 80kWh versions. A P85D Model S without Ludicrous could do 0-60 in 3.2 seconds. I see no barrier to a much lighter P80D Model 3 with Ludicrous doing well below 3.0s. And once the GF comes on line it seems like it will only be a matter of time before a P90DL 3 Model comes out that could have McLaren P1s/Bugattis/LaFerraris running scared, before the next-Gen Roadster puts them in its rearview mirror. :smile:
Tesla's ability to rapldly innovate also has to be taken into account. A 2013 P85 could do 0-60 in 4.4 seconds -- which was considered by most car mags to be very impressive at the time. Who would have guessed that only two years later, with only a slightly larger battery, a P90DL could cover the same ground in a ridiculous 2.8 seconds? You are right that even 3.1s would blow away the competition, but Tesla had no hesitation to introduce Ludicrous even when they were already blowing away the competition, and, even though, as Elon said, no customers were asking for more speed because it was "too ludicrous."
Anyway, fun to speculate! Looking forward to watching it all unfold over the next couple years. :smile:
