How much range while driving on the hills?

The e6 MPV has a 71.2kWh battery pack that gives it a range of 520km in the city. This figure drops down to 415km when you factor in highway travel as well. Moreover, the figures may vary depending on your driving style, driving conditions, tyre pressure management, timely service management, etc.

Any different in km if car runig with full seated or only with driver?
