///Drive - Trail braking



A drift-inducing technique called "the brake drift" is used in racing, involving a series of light rear brake trail-braking pulses (usually 2 or 3), followed by a momentary full-force rear braking and sharp releasing of the rear brakes. Mastering continuous trail braking as used under road conditions is a prerequisite for learning brake drifting. This is one of the most used drifting techniques in rally racing because - if done properly - allows the driver to enter and exit the corner with full throttle.

Depending upon cornering situations, techniques like trail braking can be used to maintain more speed upon entry of a corner, and attaining more grip while turning into the corner, and has an effect on apex selection. In this technique, brake pressure is applied slightly later than usual upon deceleration, and is maintained during steering input, sometimes all the way to the apex. The action of braking causes a weight transfer in the vehicle, shifting more weight from the rear of the car forward to the front tires, increasing the normal force on them and in turn increasing the amount of traction the front (steering) wheels have. Because of the characteristics of weight transfer, this technique causes weight to be shifted away from the rear of the car, resulting in lower rear traction, and can be used to induce oversteer in some cases.

///Drive - Handbrake Turn


An example of handbrake turn




The handbrake turn is a driving technique used to deliberately slide a car sideways, either for the purpose of quickly negotiating a very tight bend, or for turning around well within the vehicle's own turning circle.

The driver starts by using steering input to transfer weight to the outside tires; the handbrake is then used to lock the rear wheels, thus upsetting the adhesion between the tyres and the road surface. With practice, the car can be placed accurately by releasing the handbrake and accelerating the vehicle. The technique is used in some forms of motorsport, for example rallying, autotesting, drifting and motorkhana.

Many sports cars, especially English makes such as MG and Triumph, as late as the early 1970s were offered with a fly-off handbrake option for competition purposes—the button on the end of the lever has to be pressed before the brake will lock on, which is the reverse of the normal arrangement—allowing for faster and more controlled application in a handbrake turn, and less liable to be accidentally locked on while doing such a maneuver.

///Drive - Lift-off overteer

Lift-off oversteer (also known as snap-oversteer, trailing-throttle oversteer, throttle off oversteer, or lift-throttle oversteer) is a form of oversteer in automobiles that occurs while cornering when closing the throttle causes a deceleration, causing the vertical load on the tires to shift from the rear to the front, in a process called weight transfer. This decrease in vertical load on the rear tires causes a decrease in the lateral force they generate, so that their lateral acceleration (into the corner) is also decreased. This causes the vehicle to steer more tightly into the turn, hence oversteering. In other words, easing off the accelerator can cause the rear tires to lose traction, with the potential for the car to leave the road tail first.

///Drive - The Scandinavian Flick


This video defines clearly what a Scandinavian Flick is. 




The Scandinavian flick, Finnish flick, Manji drifting, or pendulum turn is a technique used in rallying. While approaching the turn, the driver applies a slight steering input to the opposite direction of the turn, then steering into the turn, while sharply lifting off the throttle and (in some cases, depending on speed and type of layout) lightly applying the brakes. This will cause the car to slide sideways facing slightly away from the turn. Then steering input is applied towards the turn and as the driver releases the brake pedal while still holding down the throttle the car will slingshot itself around the corner to the desired direction. Of course, countersteering will again be required to control the induced oversteer. A recent research paper initiates a mathematical analysis of this technique.


This technique is used to help the driver get around corners that have an increasing radius, but it is also used as a show off as the result of the flick involves the car oversteering heavily.
