Rev matching is a technique used in manual transmission vehicles to smoothly downshift without causing jerky movements or damaging the transmission. It involves increasing the engine speed to match the speed of the lower gear before shifting. This is typically done by pressing the gas pedal briefly while the clutch is engaged during the downshift. Rev matching helps synchronize the engine speed with the wheels, making the shift smoother and reducing strain on the car. It is commonly used in racing and performance driving for better control and smoother gear changes.
