Now that you understand the basic concept of drag, you need to understand drafting. Flocks of geese and some other birds fly in a V formation because the wingtip vortices generated by the front bird will create up-wash circulations. Neergaard, Fred. A trailing car (perhaps pushed by a line of drafting cars) uses the lead car's wake to pull up with maximum momentum at the end of a straightaway, enters a turn high, and turns down across the lead car's wake. Bump drafting can enable two cars to separate themselves from the rest of the field but also entails significant risks as a bump in the wrong location (wrong location on track or wrong location on lead car) can wreck the tandem. Pearson was reportedly worried about a slingshot maneuver from Petty and at the last minute allowed Petty to surge ahead.

As the cars are racing at high speeds, they line up with the nose of one car to the rear of the car in front of them. For the car leading, it reduces the turbulence behind the car, which slows the car down, and it reduces the pressure on the nose of the car that is following. At the Daytona 500 in 1999, Jeff Gordon fended off a nose-to-tail challenge from racing legend Dale Earnhardt. Drafting, as mentioned before, is used only on fast-paced tracks like the ones at Tallagada and Daytona. 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. Both sports use pace lines - long lines of racers exploiting slipstream physics, as well as what is referred to as "pelotons" in cycle racing, or large packs of racers reducing pressure drag. They may also add a small bump and just that fast, a potential first place finisher moves to the back of the field. This is referred to as negative lift in aerodynamic-speak and racers typically seek to increase this effect. The less drag you have, the faster you can go. It's all about guts and brains and ability -- and one of the most critical abilities is understanding the draft, or as many drivers put it, "seeing the air.". However it is very difficult for cars to follow each other close together in fast corners as the "dirty" (turbulent) air that comes off the lead car unbalances the trailing car as its aerodynamic devices provide less grip. The technique is used to attempt a pass. Drafting can be cooperative: several competitors take turns in the lead position (which requires the most effort and energy consumption). As this happens the nose of the lead car begins to raise a little adding an upforce to the equation. The Daytona 500 runs in three stages where drivers in the lead can earn points. Video explaining what the term drafting means and how drivers use it to there advantage. Side drafting is a technique that drivers mostly employ when they intend to pass the leading car.
