Revolutions Per Minute (RPM)
What does rpm mean in a car?
RPM stands for revolutions per minute and is a measure of how fast the engine is spinning. The faster an engine spins, the more power it makes. At a higher RPM, the engine is burning more fuel, so it makes more power and consumes more fuel. In the instrument display, RPM is shown in a tachometer (also known as a rev counter) in multiples of thousands.
