What does "pushing the head" mean in racing?

Pushers are mostly rear-wheel-drive cars out of control, and the key word here is push. The so-called rear drive means that the rear wheel of the car is the power output wheel, the front wheel is the driven wheel only responsible for steering, and the body is "pushed" from back to front.

This driving mode is the most ideal scheme for sports or heavy vehicles, because the center of gravity will move backwards when the vehicle starts to accelerate, that is, the body will sink backwards.

The front wheel driven by the rear wheel has no power output, and this passive rotating state has no ability to correct the posture of the car body in the case of out of control. For example, when driving on a wet road, the torque of the rear wheel is not greater than the friction coefficient, so that the vehicle can normally output power to drive.

Matters needing attention

When the center of gravity moves backward, the vertical pressure exerted by the rear wheel increases synchronously, and the vertical pressure is equal to the grip of the wheel. Therefore, when the rear wheel is driven and accelerated, the rear wheel grip is stronger and the front wheel grip is much weaker;

When driving on a normally paved road, the rear wheels can start with enough ideal grip and friction. At this time, when the wheel torque is less than the friction force, the wheel will not slip obviously, and the power loss on the wheel will be much smaller, but it will be more troublesome when the road is wet or cut short.
