I've just been for a ride in someone's Nissan Leaf - it was
impressive, so quiet and amazing acceleration.

Do electric cars have a gearbox (an automatic one I presume)? Or does
the motor just run faster the faster you go? I was told by the owner
the optimum speed for economy of battery usage is about 55mph.

It doesn't sound like it's changing gear.


No gearbox or clutch.
