What is hypermiling? HID? DWL? (driving with lights?) Gliding? Has this word replaced "coasting"? ICE? (internal combustion engine?) Traction engine? Is the electric motor? And I've read others commenting on the vehicle proximity warning sound, but our C doesn't seem to make any noise other than the faint whining/whirring of an electric engine. Also, I've had my C2 for almost a month now, and the "battery" indicator on the energy monitor screen has never reached full capacity. At best it is one bar short of full. Does this mean I'm doing something wrong, or is the car still breaking in? I've not hit the 700 mile mark yet. Thanks!
