ONCE UPPON A TIME...
Many attribute the return of drifting as a competitive sport to mountain-road racers of rural Japan. Informal challenges on back mountain roads (called Touge pronounced "Toh-gey") eventually evolved into a heavily funded and advertised competitive events, sanctioned by organizations and held on private tracks. Drifting began in the United States in 1996 with an event at Willow Springs racetrack in California hosted by the magazine Option, but it did not become popular until around 2002, and has since exploded into a massively popular form of motorsport. Japanese drifters are still considered to be at the cutting edge of technique and car development, but their American counterparts are quickly catching up.
As rumor has it, Keiichi Tsuchiya was in a car race, and was dead last. He decided to swing the car around the corners, shocking and amazing the crowd. When accessed later for comment, Tsuchiya called it "drifting." While this is not the origin, it is probably where it obtained its name and introduction. In 1977 Keiichi began his racing career driving many different cars in amateur racing series events. Racing these underpowered cars was difficult but again a great learning experience. Later Keiichi was picked up to drive the ADVAN sponsored Toyota AE86/Sprinter Trueno (JDM Corolla GT-S). During many races on a downhill corner he would drift the car and carry a better corner speed than his competitors. This technique is what made him the Drift King, not, as most believe, that he was first in the drift scene.
Many of the techniques used today in drifting were developed by rally drivers competing on dirt, gravel and snow. On such surfaces, the fastest way to take a corner is generally by sliding.
AND TODAY...
Nowadays, drifting has evolved into a competitive sport where drivers compete in rear-wheel drive cars to keep their cars sideways as long as possible. At the top levels of competition, especially the D1 Grand Prix in Japan, Australia, the United Kingdom and the United States, drivers are able to keep their cars sliding for extended periods of time, often through several turns. Drifting competitions are judged based not on the time it takes to complete a course, but on line, angle, speed, and show factor. Line involves taking the correct line, which is usually announced by judges. Angle is the angle of a car in a drift, the more the better. Speed is the speed entering a turn, the speed through a turn, and the speed exiting the turn; faster is better. The show factor is based on multiple things, such as the amount of smoke, how close the car is from the wall, and falling aero. It's based on how "cool" everything looks. Final rounds of competition often include tandem 
drift runs nicknamed "tsuiso" (chase-run) in Japanese, where one car follows another through the course, attempting to keep up with or even pass the car in front. In the tsuiso rounds, it doesn't matter if the racing line is wrong; it matters who has the most exciting drift. Normally, the leading car usually produces a max-angle, but still close off the inside a little to prevent passing. The chasing car usually drifts with less angle, but very close to the lead car. But a car does not even have to keep up, and in fact in some cases a car that was left behind on the straight produces a beautiful drift, winning him that round. A spin, understeer, or collision results in a disqualification of the offending party.
To make judging less ambiguous, the DriftBox has been introduced, which uses GPS to measure the angle, speed and g-force during a run. This takes out the guessing element when it comes to judging the angle and speed of the drift.
IN CANADA
The first official drifting competion has been held in St-Eustache in October 2004 organised by a young organisation called Drift Mania today known as DMCC. Behind all this there were two gentleman who made this sport known in Quebec and we would like to thank Marco Santos and Haig Kanadjian who made the first public presentation ever during a tuning show before that summer...
