Highly unlikely. First you must remember that the mass of the model 3 will be significantly higher than that of the roadster making it nigh on impossible to achieve the stated range with such a low capacity. All reasonable calculations come up with a value between 45~50 kWh for the model 3.It is also unlikely that the model 3 will use the same batteries as the 70 kWH pack of the roadster 3.0. The roadster 3.0 simply uses the panasonic 3.1mAH cells rather than the less capacious 2.1mAh cells of the older roadsters. Panasonic has several better cells available, and as increased density is one of the best ways that you can reduce costs, so you can bet that the gigafactory produced cells will be significantly better than the ones in the roadster 3.0.Hope that helps.
