Heel-and-toe

The heel and toe technique is applied in motor sports nature of the incident gas, which is used in vehicles with manual transmission.

The heel and toe technique - in the art also called Heel and Toe Downshift - is a rather complicated technique. It refers both feet, the driver's right hand, and all three pedals with. The speed of the motor to be smoothly adjusted to that of the drive train when the vehicle is braked. Also characterized the clutch wear is reduced and the vehicle (assuming correct use ) more manageable for the operator.

A "normal" ( maybe a bit inexperienced ) drivers keep switching back:

If the speed is too low, the driver disengages the clutch, puts a low gear and coupling again. The synchronization of the transmission take in today's vehicles, the synchronizing rings. Engages the driver now in lower gear back on, the engine would have to immediately adjust its speed to the drive train. This means that the vehicle is jerky and the clutch and the engine are highly stressed, which leads to high clutch wear, as they must grind for a smooth engagement long. The experienced drivers compensate for this by bucking switching back to the appropriate gear and smooth engagement.

A suitable technical solution is to adjust the motor speed to the drive train. The driver before connecting a short burst of gas, which can be engaged soft again and the clutch is spared. In road traffic, this technique would be sufficient for the motor sport but this is too slow.

Therefore in motorsport the heel and toe technique is applied. This allows for braking and downshifting at the same time. After that, the driver can accelerate earlier and faster. In motor sport, this technique is almost indispensable, but it can also be helpful in normal traffic:

This procedure describes how to heel and toe technique with double domes. The engagement before the gas shock is used in non-synchronized gears, which are used in many race cars, the adaptation of the speed between the input and output shaft. It is possible to skip steps 4 and 6. Then, however, the gas shock must be greater, so that the input shaft is accelerated by the same amount as in the engaged state.
