It also permits the rear car to transfer energy forward by bumping the lead car or to build momentum for a pass. How does drafting work? By tailgating, the same effects of reducing drag will pull a car along in the wake of the truck and add a few miles per gallon as the smaller car's engine works less. They may also add a small bump and just that fast, a potential first place finisher moves to the back of the field.

Why is it so hard to understand the NASCAR penalty system? Normal drafting is drafting by a car driver by staying as close to the rear of the leading car as possible to avoid the turbulent flow from the leading car. The end result is a car that's harder to pass and harder to draft. Along a long straight a car following close behind another uses the slipstream created by the lead car to close the gap between them, hoping to be able to overtake the leader under braking for the next corner, or if they have a straightline speed advantage, to pass on the straight. [4], In recent years, as aerodynamics have become increasingly critical to the performance of stock cars on "intermediate" oval tracks (between 1.33 and 2 mi) and superspeedways not requiring restrictor plates (such as the Indianapolis Motor Speedway), the effect of turbulent, or "dirty" air when following closely behind another car has become much more akin to that described above in open-wheel racing (a situation described in NASCAR circles as aero push), and is often cited as a main reason for a decrease in the amount of overtakes.

Drafting in racing is an aerodynamic technique in which two cars align closely together, reducing the overall drag by making use of the lead car's slipstream. It can also be disastrous, so it is a. Drafting is one way to conserve fuel as well as avoid burning out the cars engine before crossing the finish line. This technique is very similar to standard drafting.In this scenario, the trailing car bumps into the lead car rather than keeping its nose pressed into the back of the car.This technique can be dangerous, as the car that gets bumped into may lose control and crash or cause other crashes.The results of bump drafting offer the same speed advantage that normal drafting has.
