okay so i came across this just a couple of moments ago. i really like rally racing and my favorite driver is ken block and this is his new video. heres a brief summary of what gymkhana is. Gymkhana is a type of motorsport practiced in an increasing number of countries. Similar to autocross, gymkhana courses are often very complex and memorizing the course is a significant part of achieving a fast time.
Gymkhana events are time and/or speed events in an automobile. These can feature obstacles such as cones, tires, and barrels. The driver must maneuver through a predetermined "track" performing many different driving techniques. What separates gymkhana from traditional autocross events is that the gymkhana requires drivers to perform reversals, 180 degree spins, 360 degree spins, parking boxes, figure 8s and other advanced skills. Drifting is also encouraged where helpful or necessary. Essentially, a gymkhana is any event featuring a starting point, a finish line and some sort of "obstacle" to get through, around, or by, all within a certain time limit.
