FutureStarrDrift a car
The origins of the term drift are murky, but what’s understood is that the term had its roots in the sport of drifting. In that sport, drivers would accelerate, turn their steering wheel to the left or right, and then brake to bring the car to a stop.Are you adventurous by nature, always trying something new or blurring the border between safe and dangerous? If so, you may have tried, or want to try, drifting. Drifting is a driving maneuver where the driver of a car intentionally steers too much, causing the car’s rear tires, or sometimes all the tires, to lose their grip on the road. Drifting is the driver’s way of squeezing thrill from a very unusual and unsafe driving maneuver.
When your car performs a drift turn, centripetal force comes to bear. It pulls your car in a circular motion, which is exactly what you need to execute the drifting maneuver. As you drive, your car is going straight. It will remain going in the same direction until you apply force for it to do otherwise. When you take the turn, static friction will grip the front tires to prevent the vehicle from skidding or sliding along the straight path. Static friction will ensure that the car is taking a turn.
The technique causes the rear slip angle to exceed the front slip angle to such an extent that often the front wheels are pointing in the opposite direction to the turn (e.g. car is turning left, wheels are pointed right or vice versa, also known as opposite lock or counter-steering). Drifting is traditionally done by clutch kicking (where the clutch is rapidly disengaged and re-engaged with the intention of upsetting the grip of the rear wheels), then intentionally oversteering and countersteering. This sense of drift is not to be confused with the four wheel drift, a classic cornering technique established in Grand Prix and sports car racing. (Source:en.wikipedia.org)
The D1GP drift series has been prototyping and fine-tuning an electronic judging system based on custom sensors that record and transmit car data to a computer that judges the run. This system is also being tested in some European series. It is designed to remove subjectivity and/or predisposition of judges. Usually the track for such a system is broken up into several sections (usually three) and the system automatically generates scores based on speed, angle and fluidity of the driver in each section, combining the scores for the final score. In certain situations judges can change or overrule a score, which happens, though rarely.
Drift cars are usually light- to moderate-weight rear-wheel-drive coupes and sedans, offering a large range of power levels. There have also been all-wheel drive cars that have been converted to rear-wheel drive such as the Subaru WRX, Toyota Avensis, Scion tC, Mitsubishi Lancer Evolution, Dodge Charger, and Nissan GT-R. Early on, AWD cars without conversion were allowed in some drifting competitions, and usually the rules allowed only a certain percentage of power to be sent to the front wheels, but they are banned in most (if not all) drifting competitions today.
