Rev Matching

Drivers do it with a throttle blip, often using the heel-and-toe technique while braking. Many modern manual and automatic cars can do it automatically. It reduces wear on the clutch and stops the rear wheels from locking on a hard downshift. Rev-matching systems usually switch on in sport modes and can often be turned off.

With the clutch disengaged, a quick press of the accelerator raises engine revs to suit the road speed in the lower gear.

Practise in a safe place before using it in traffic. Avoid over-revving by choosing a sensible gear for the speed.
