Modern methods for aerodynamic drag reduction of road vehicles

This work is focused on the summary of the elements that contribute reducing aerodynamic resistance of vehicles. Aerodynamic drag is about one-third of the total resistance of the vehicle. Just today, in the 21st century it is a big effort to eliminate excess combustion and consumption of the car, and here plays a big part of the resistance of the vehicle. For analysis are already using computer simulations that greatly increase the efficiency and speed of construction
