The road racing is a form of racing which takes place in circuits paved (particularly road courses, but also temporary circuits as street circuits), played with a format of stroke : the goal is rotated a specified number of turns in the lower possible time, or turn as many turns as possible in a given time. The main types of cars used in speed racing are cars, large cars, sports prototypes, and stock cars.
Speed racing clearly differs from rally and raid rally, which run in separate sections. The skids, the rallycross, and the autocross also run in circuits, but in the first case, the objective of the race is not to be fast, but to skid with the car, and in the rest, the surface is not paved.
A speed racing date can be composed of up to four different parts: training session, qualifying round, qualifying races, and final race.
In the training or practice session (possibly several), the participants drive around the circuit, evaluating its characteristics and the behavior of the car. To improve lap times, the rider modifies the different adjustment parameters of his machine (suspension, tires, brakes, etc.).
In the qualifying or qualifying round, pilots must do laps as quickly as possible to the circuit. Depending on the competition, pilots may be restricted to spin a certain maximum number of laps and may drive alone or simultaneously. In certain championships, there is a superclassification, which forces the top-ranked drivers to turn again, usually without the presence of their rivals on the track.
The final race is the one that awards points for the championship. Long riders placed on a starting grid, sorted according to the results of the qualifying round. The pilots start and compete simultaneously, trying to reach the finish line as soon as possible once the time or laps previously stipulated have been completed. Usually, the circuit has a pit area where teams can repair damaged cars, refuel, replace tires and, in endurance races, change drivers.
In some championships, prior to the final race, they jostle sleeves or qualifying races, which usually last less than the final race and give few points (or none) for the championship. For example, in Road Tourism, the pilots are divided into three groups according to the results of the classification: 1st, 4th, 7th run the first round, 2nd, 5th, 8th run the second, and the 3rd, the 6th, the 9th run the third. The starting grid of the final race is assembled according to the arrival positions of the pilots in the three qualifying races, alternated in a similar way. In the same way, the starting grid of the 500 Miles of Daytona is formed according to the results of two sleeves, whose output order is determined from the result of the qualifying round. In other cases, there is no single final race, but two or three sleeves. It is common for each race to have a different round of qualification.
On the other hand, in the World Touring Car Championship, the only qualifying round determines the starting order of the first round. The grid of exit of the second sleeve is formed according to the order of arrival of the first sleeve, with the first eight inverted pilots. The GP2 Series uses the same system as the World Touring Car Championship, with the difference that the first race is longer and awards more points than the second.
