What Is Rev Match?
A rev match, or rev matching, is a technique that allows smooth driving for cars with a manual transmission, also known as a stick shift. Only professionals should attempt rev matching without supervision.

Function
-
Rev matching allows for smoother stick shift driving by allowing the fastest acceleration during the process of down-shifting gears. When driving in the a specific gear, a driver can accomplish rev matching by increasing the throttle, down-shifting quickly to the required gear and rapidly releasing the clutch.
Benefits
-
Eliminating excess weight, or the G-forces from acceleration, can lead to a rapid transfer and improve the driving experience. Rev matching can also improve technique by increasing smoothness and can lead to faster speed and better lap times.

Considerations
-
Rev-matching is not a recreational activity. Those who are qualified to attempt this technique may notice a forward weight transfer that could feel jolt-like. According to the Driving Fast website, rev-matching also carries the risk of causing the car's wheels to lock.
