Do electric cars have gears?

The simple answer is 'No'!  This is because they don't need a clutch as power is delivered immediately, so revving isn't needed.  Electric cars have a simple switch which mimics the settings of a gearbox.  This switch or lever, allows the driver to simply select 'Drive', 'Reverse' or 'Neutral' - very much like a conventional petrol/diesel powered automatic car.

Some EV's allow the driver to change the settings of the vehicle, to either economise on power, or the reverse - with 'Sport' settings.  Needless to say, utilising such settings will either increase or reduce the range of the charge respectively.
