I said if a 500+ range car is needed. I believe that shortest distance is take what will likely be the lightest car at the time. My assumption is the Model 3 will move to front and rear single castings and structural pack after substantial Model Y production moves to Austin. Allows Model Y line in Fremont to go offline and new Model 3 line to support new version to be built. Then start migrating existing Model 3 lines.You think selling the 3 with more range than an S is a good idea?
Y line(s) move to Austin
Y line is converted to new 3 line
old 3 line is shut down and converted to new 3 line
old 3 line is shut down and converted to new 3 line...Rinse and repeat until all lines converted.
If Y continues production in Fremont as well as Austin then start converting them as well as Austin ramps
Honestly at that point does it really matter if the Model S is the longest range Tesla? Typically with most cars the best mileage is the smaller cars. People expect that.
