To reduce the fuel consumption of conventional cars and increase the autonomy of electric vehicles, it is important to develop measures to reduce air resistance. The measures taken today to achieve a car aerodynamic body can lead to significant reductions in fuel consumption and on the other hand, these measures impose the reduction of useful volume of the vehicle minimizing the cross section especially in the back area. In addition, in addition to the effect of reducing air resistance, the new active devices allow the production of usable electric energy through the action of drag forces, energy that can be stored in automobile batteries. With the new solution to reduce air resistance, it is not necessary to minimize cross sections at the rear and cars can be achieved with a maximum useful volume. In the case of a classic car, with the new system to reduce the resistance of the applied air, we could obtain a reduction in fuel consumption by approximately 10 - 30%. The maximum reduction is obtained at high running speed. The new type of system to reduce aerodynamic drag can generate the necessary power for the maintenance of the car, reducing further consumption. In the case of the electric car, the new type of devices could decrease energy consumption due to reduced air resistance and can also produce electricity while moving. The new electric cars, with the new type of devices will have more autonomy with about 20 - 40% compared to the current electric cars. The basic idea is to make the aerodynamic forces of resistance to produce energy during the running time of the automobile without increasing drag. Another advantage of using active system devices to reduce the drag of cars is given by the fact that it can be used to increase the maneuverability of the vehicle in conditions of low adherence to the road.
