Electric motors can have full torque throughout their entire RPM range, so unlike a standard car that needs a gear box to keep them in the ideal range, an electric car (like a Tesla Model S) doesn't necessarily need them. So I too wonder why they're using gear changes. Maybe based on whatever gear reducer they're using, the motors just aren't rated at enough RPM. I'm sure it was all figured out by someone 100x smarter than me so there's a good reason I'm sure.
