How NASCAR Pre-race and Post-race Inspection Works. Drafting is only employed when drivers have almost reached the limit of their speed and are striving for more. Something else that one should be focusing on when making daily fantasy NASCAR lineups is the idea of place differential. [4], Drafting was discovered by stock car racers in the 1960 Daytona 500, when Junior Johnson found that he could use drafting as a strategy that helped him overcome the fact that his Chevrolet could not keep up with other cars, allowing him to win the race. NASCAR constantly innovates - in engineering research around vehicle safety, new and evolving content delivery for our fans, and best business practices to keep NASCAR efficient. Dr. Jerre Hill said he was skeptical about the process, and that the math and physics didn't quite mesh with the reality. Bodine also said lead drivers often shift from one drafting lane to another as need dictates. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns.

Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. Boone, Jerry F. "Restrictor Plate Racing - Alternatives to Mayhem." If worst comes to worst and the race has to stop, the driver in the lead after at least 100 laps or the end of Stage . Although drafting presents a lot of overtaking opportunities, it also takes a lot of concentration from the trailing driver. [12], On the show MythBusters, drafting behind an 18-wheeler truck was tested and results showed that traveling 100 feet (30m) behind the truck increased overall mpg efficiency by 11%. Bodine said the days of practice leading up to a race allow each driver to get to know the other cars. In tandem drafting, any sudden action by the leading driver is bound to lead to a crash. Whatever lane they lead will go just a little faster than the one they just left. Normal drafting, bump drafting, and side drafting are all permitted., Normal drafting is the most basic form of drafting and involves one car closely tailing the leading car in order to get inside its slipstream and reduce overall drag.Normal drafting benefits both cars: it benefits the following car by reducing the drag of airflow in front of it, and it helps the leading car by reducing turbulence behind it, improving its own drag.However, as with all forms of drafting, normal drafting can be dangerous, as if any one car veers out of the formation, a wreck could occur.. Drafting's importance as one of the techniques and strategies to win a race has as much to with the driver as the car. . With more than 800 horsepower being produced in some races, downforce is maximized to stick the car to the track. For example, a double bogey is worth -1, where a birdie is +3. Both, the leading and the trailing drivers can take steps to disrupt the others strategy. The following driver can also pull a similar tactic, inching up on the car ahead in order to disrupt the flow of air over the lead car's body. The second car can slip into that disturbed air stream and reap the benefits -- that is, if the driver is talented. Or they may try to stay away from a bad pusher, like Denny. When a vehicle is racing it encounters resistance from the air.

Having laid the foundation for our new knowledge-engorged racing brains, drafting can thus be understood as the aerodynamic technique where one car closely aligns its nose inches away from the lead car's bumper. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the . By staying close to the lead car the trailing car interrupts that low-pressure system and cuts down on its effects. These are super-fast tracks with good banking on the turns where drivers can push their cars to the limit throughout the race. That same reduction also benefits the lead car as the presence of the trailing car reduces the pressure drag off the back of the lead car. While their earnings vary, a good year can also mean over $130,000 for a race if they finish at the top. The end result is a game of very small numbers and percentages and those numbers play out in body design and driving skill -- which, of course, includes drafting. 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.". The trick to drafting is to figure out the person in front of you and use their car to push the air away. This means finding the sweet spots on a potential lead car's bumper for the draft, and in more advanced driving situations where to place your car in front of or behind another car to deprive them of downforce, increase their drag, or even rob them of an opportunity to pass. Video explaining what the term drafting means and how drivers use it to there advantage. You will also have to adjust how you do things according to the driver in front of you. The final round is the season finale and the . Side drafting can also work, but this is used more for passing than gaining speed.

NASCAR 21: Ignition is playable with a handheld controller primarily, but can also be played with select racing wheels. At superspeedways, downforce is purposely reduced since the track layout requires higher speeds on the straightaways. In cycling, any time one bicyclist is riding behind another, energy is conserved, especially at higher speeds. As a result, drafting cannot be achieved throughout the entire race due to the engines overheating. At the conclusion of the 26 races in the regular season, a regular-season champion is crowned and awarded 15 additional points for the playoffs. 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.
