In an automobile transmission, the lowest gears generally convert 3 to 4 revolutions of the engine into a single revolution of the drive shaft. These gears are said to have a 3:1 or 4:1 ratio. These gears provide more torque and power in order to quickly accelerate a car from a standstill or low speed.

The higher gears, however, need less torque and power in order to simply maintain a high speed, and so there gearing ratios are generally less than 1:1 - sometimes 0.8:1 or 0.75:1. This means that for every 0.75 turns of the engine, the drive shaft makes a complete revolution. Gears with ratios of less than 1:1 are referred to as overdrive
