Overdrive is simply a set of gears. Unlike the lower gears where the gear ratio is above one, overdrive is a gear somewhere between 0.6 to 0.8:1. This means that the wheels of the vehicle will rotate more per single-engine rotation, allowing the engine RPM to remain low, while the speed remains high.
