Do electric cars have transmissions?

Electric cars don’t require multi-speed transmissions because of the so-called “engine” in an electric car, an electric motor. While internal combustion engines require multiple gears with different ratios for power output, electric motors produce a consistent amount of torque at any given RPM within a specific range.

What size battery is in an electric car?
