They do not have transmissions.  The engine drives an electric generator
producing about 600V DC.  Power is then distributed to electric motors
connected to the wheels.  Generally there are twelve motors--one per wheel.
This setup takes up less space than a clutch and transmission and produces
high torque over a large range of speeds.
