I wonder what the reason is for no 40kwh model X
If the X has a 10% range penalty over the S then a 40kwh X is only a 145 mile car.
Does Tesla think that is too limited?
Another factor might be that the model X is likely to be more expensive. do they think nobody will buy a $60k 145 mile SUV when $10k more bumps you to a 210 mile SUV?
