BASIC PARAMETERS AND GENERAL CONSTRUCTION arrangement of the fast cars 
Basic parameters and constructive line-speed vehicles are determined primarily by their purpose. 
Production cars adapted "to sporting purposes, and sports cars have a conventional passenger car lineup constructive, and especially race cars are mostly original designs and their overall line up do not look like production cars. 
The following are the main conditions affecting the construction of racing cars, and major constructive scheme adopted at the present time for these automobiles. 
Constructive line-up for the race carhangs on for any type of competition he intendedchen. First of all, reveals the main difference between a record-racing cars, designed to establish a record for short distances, and road-racing cars, designed for longare positive road racing competition.

Typical of the record-racing cars are the cars of the "Star" in classes up to 250, 350 and 500 cm 3. 
Road-racing cars have: 
1) high dynamic qualities (Suitable to develop and implement a high speed rapid acceleration); 
2) good stability and handling, ensuring safety; 
3) sufficient durability and reliability for business continuity in long-term events; 
4) high mobility (especially when racing circuit). 
To obtain high dynamic qualities are needed: 
1) big engine power; 
2) a small area of the drag and streamlining is a good car; 
3) small car weight; 
4) high efficiency of power transmission; 
5) the right choice of gear ratios and final drive gear; 
6) a special type of tire with a high internal pressure. 
On modern racing cars are set special motors with a high-liter capacity. 
Much of the power race car is spent overcoming air resistance. Therefore, when developing an overall kompanovki car racing tend to reduce losses by reducing surface drag of streamlining and improving the car. The joint solution of these two problems presents a great difficulty, since the best results in streamlining provide cars with wheels, closed fairing, made with a body, and this leads to some increase in the area of drag. 
Vehicles with open-wheel gives the least area of any resistance, but the worst streamlining. 
Currently, most road-racing car has a body with open wheels.
