Note: edges will be rounded, this is not the most accurate model of a car ever.
This is what I think would be the most aerodynamic choice, but unfortunately it would severely limit space for batteries to go.
I know it isn't the ideal nose, as it isn't blunt at the front. But my understanding is that a blunted nose works by increasing the pressure so that the flow adheres to the tail better. In this case there isn't a tail behind it, but rather the windshield, so I don't think that blunting it would help aerodynamically, but it would certainly give more room.
Next set of pictures will be of a nose design with more room, but still fairly aerodynamic.
