5 colors
2 battery sizes (10 options total)
2 wheel sizes (20 options total)
2 cold wx or no options (40 options total)
2 Interior packages (probably includes sound) (80 options total)
AP not counted because it is software only.
Actually this seems too restrictive, anyone have a different interpretation of what <100 configurations means?
I think the total number of configurations cannot be calculated this way. Remember there is also a rumor that configurations will be more "streamlined" in the Model 3 which means we cannot iterate on all combinations - there will be constraints.
So lets look at it this way:
* Colors { 5 choices }
* Drivetrain { RWD, AWD, P-AWD }
* Battery { Base, Large }
* Interior { Base, Premium }
* Wheel { 18, 20 }
Total hardware configurations = ( 3 x 2 x 2 x 2) = 24 and here is how the 24 hardware configurations could be constrained:
RWD, BaseBattery, BaseInterior, 18' wheel
RWD, LargeBattery, BaseInterior, 18' wheel
RWD, BaseBattery, PremiumInterior, 18' wheel
RWD, LargeBattery, PremiumInterior, 18' wheel - Not a valid configuration
AWD, BaseBattery, BaseInterior, 18' wheel - Not a valid configuration
AWD, LargeBattery, BaseInterior, 18' wheel - Not a valid configuration
AWD, BaseBattery, PremiumInterior, 18' wheel - Not a valid configuration
AWD, LargeBattery, PremiumInterior, 18' wheel
PAWD, BaseBattery, BaseInterior, 18' wheel - Not a valid configuration
PAWD, LargeBattery, BaseInterior, 18' wheel - Not a valid configuration
PAWD, BaseBattery, PremiumInterior, 18' wheel - Not a valid configuration
PAWD, LargeBattery, PremiumInterior, 18' wheel - Not a valid configuration
RWD, BaseBattery, BaseInterior, 20' wheel
RWD, LargeBattery, BaseInterior, 20' wheel - Not a valid configuration
RWD, BaseBattery, PremiumInterior, 20' wheel
RWD, LargeBattery, PremiumInterior, 20' wheel - Not a valid configuration
AWD, BaseBattery, BaseInterior, 20' wheel - Not a valid configuration
AWD, LargeBattery, BaseInterior, 20' wheel
AWD, BaseBattery, PremiumInterior, 20' wheel - Not a valid configuration
AWD, LargeBattery, PremiumInterior, 20' wheel
PAWD, BaseBattery, BaseInterior, 20' wheel - Not a valid configuration
PAWD, LargeBattery, BaseInterior, 20' wheel
PAWD, BaseBattery, PremiumInterior, 20' wheel - Not a valid configuration
PAWD, LargeBattery, PremiumInterior, 20' wheel
So now we only have 10 valid hardware configurations which when multiplied by 5 colors gives only 30 configurations rather than 120 which is what we would get if all combinations are valid - just as an example.
