Using Ford’s F Series as an example, the truck’s power, suspension and load capabilities are clearly differentiated by the nameplate, F-150, F-250, and F-350. Had Ford not done this, every F series truck would become Model F with either a 150, 250 or 350 badge. Presumably, Model E’s badges will be similar to Model S with two separate nameplates, one Model E nameplate and another power option (45 or 60) nameplate. Would it make more sense if Model 3 were offered in a series with each battery size having it’s own individual nameplate? Example: 45kwh = Tesla E-45 60kwh = Tesla E-60 Changing to a series could be positive for both Tesla and Tesla’s customer: As a customer, when the time comes to resell my E-45 or E-60, it would be (more) directly compared against other E-45 or E-60s rather than every Model 3 available on the resale market. For Tesla, if slight body changes or trims need to be made to accommodate for something specific to one vehicle but not the other (i.e. more airflow to cool a larger battery), the change could be made to fewer vehicles. Note: to be clear, we don't know what size battery Tesla will offer in Model E, 45 kwh and 60 kwh are a guess.
