This position gives both the cars an advantage of additional speed as well fuel efficiency. Failure to do so can lead to disaster. To truly understand the science of drafting, you need to know what drag is and how it affects every car on the track. [11] Some sources say that the most common tailgating does not save gasoline even at freeway speeds because one is likely to accelerate and brake so frequently that any aerodynamic savings are lost through the brakes.

The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the . This works because it reduces the air particles hitting the front of both cars. Drafting or slipstreaming is an aerodynamic technique where two vehicles or other moving objects are caused to align in a close group, reducing the overall effect of drag due to exploiting the lead object's slipstream.Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure required to maintain a . The leading driver can slow down and stay close to the trailing driver thereby depriving the rear car of sufficient air to cool his engine. The United States military has been all-volunteer since 1973. The final round is the season finale and the .

Add to that the restrictor plates that limit the amount of air intake to the engine and restricts the speed of the car. Teams, sometimes official but often an informal collaboration, use the power of drafting to rocket members past the competition, vie for the best track real estate and even steal the race lead at a moment's notice. The cookies is used to store the user consent for the cookies in the category "Necessary". The trailing car drafts the lead car, uses the pressure reduction to ease its movement through the air, waits for the right curve, mashes the gas and uses the extra power to slingshot ahead for the race victory. It is not something that you can watch on a video screen and become a master at. In order to ride very fast, a team of some skilled cyclists may form the "Belgian tourniquet".

The combination of running downhill and running across the zone of lowest aerodynamic drag allows the trailing car to carry extra speed and pass on the inside of the leader. Racing legend Junior Johnson is acknowledged as the first driver to use drafting as a competitive tactic. (Dec. 3, 2008)http://www.hypermiling.com/, Mark Martin's Unofficial Home Page. Milnes, Ken.
