Air flows around the car as it screams around the track and each minute flow of wind along the hood, windshield, fairings, doors, spoilers and air dams has a subtle effect of increasing or decreasing the air pressure on every surface of the car. Have you ever wondered what drafting is in NASCAR and how does the draft work?

This is referred to as negative lift in aerodynamic-speak and racers typically seek to increase this effect. After Ryan Newman's scary crash in the 2020 Daytona 500, NASCAR made efforts to change drafting at superspeedways, where less horsepower was used: the removal of aero ducts to eliminate tandem drafting and decrease closing rates, and a smaller throttle body to lower the amount of air into a racecar. In NASCAR, the advantage is so great, that car trying to join a draft has to initially be in a favorable position as the draft line goes by him (low on the track, to a high draft line), and have some reserve .

Additionally, on the same episode, Mythbusters demonstrated that it can be very dangerous for the following car if one of the truck's tires (or their recaps) delaminate, as the chunks of ejected rubber can be large enough to cause serious harm, even death, to a driver following too closely.[14]. 1. "That's what we do when we practice; we get up close to the other cars, see what happens to our car and theirs. It also helps the leading car increase its speed by reducing the drag on the car because the trailing car gives a smooth flow to the air coming off the leading car.

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. This is in large part due to drafting where an understanding of the physics involved allow drivers to help reduce drag and gain a few more miles per hour (kilometers per hour) in the process. Studies show that birds in a V formation place themselves roughly at the optimum distance predicted by simple aerodynamic theory.[21].
