Double clutching: It's one of those terms car enthusiasts often use to describe both what they've done in their own cars and what makes a good clutch.
But how many of us really know what double clutching actually means? Jason Fenske over at Engineering Explained has a knack for making things clear without glossing over the details.

In this latest video, he goes over both the mechanical description of just what it means to double clutch and what makes a clutch system, including the pedal, more effective for double clutching.
Initially, double clutching began as a necessity for unsynchronized gearboxes, the kind of transmission that largely no longer exists in new vehicles. Today, double clutching is more closely related to heel and toe shifting, when both the gas and brake pedals are depressed. Heel and toe shifting allows drivers to match a vehicle's engine speed to the selected gear while providing the maximum amount of braking available.
In essence, double clutching and heel and toe shifting is what modern dual-clutch gearboxes with rev-matching attempt to replicate.
Watch the video and, if you happen to drive a manual transmission car, you can go practice on your own.
