Rev matching
01
the technique of adjusting engine speed to match the rotational speed of the transmission input shaft before gear engagement
Example
Learning rev matching requires precise coordination between the throttle and clutch pedals.
Race car drivers often practice rev matching to maintain control and stability during high-speed cornering.
Rev matching helps to smoothly shift gears in a manual transmission, reducing wear on the clutch.
When downshifting, rev matching prevents the vehicle from jerking or lurching forward.
Modern cars with automatic transmissions often use electronic systems to simulate rev matching for smoother gear changes.
