Hill, Dr. Jerre. Let's start with the basics. Johnson discovered during qualifying heats that if he pulled up close to the competition, within a few inches, he could keep pace with the bigger and faster vehicles. [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.

Vehicles no longer have sufficient horsepower or throttle response to maintain their drafting speeds upon exiting the draft; they can pull out and squeeze ahead but lack the response to clear the car being passed. 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. Cross-country skiing and running use variations of drafting, too. Pulling within a car length of a lead car benefits the trailing car by reducing drag. Place Differential = (Starting Position) - (Finishing Position) Example: If a driver starts in 20th position and finishes in 10th place then his Place Differential is +10.

Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. The second car can slip into that disturbed air stream and reap the benefits -- that is, if the driver is talented. Pressure drag has to do with the low pressure created as the air moves around the object. This penalty almost makes sure that the drivers have no chance of finishing the race in a respectable position. Romberg, Kurt. 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 certain speed and can also slightly reduce the energy expenditure of the lead vehicle or object. Soon the pressure differential is enough for the windows to shatter out from the higher interior pressure. If you enjoyed this article, then you may want to take a look at the next page, too. DK awards 0.25 points for Laps Led . He has to also anticipate and react to the actions of the driver before him quickly if he is to avoid a crash.

Bump drafting is when a trailing car bumps the leading car lightly and then follows the car closely to take advantage of the draft. Boone, Jerry F. "Restrictor Plate Racing - Alternatives to Mayhem." Drafting uses the air molecules around the car that is created by the force of the forward motion. The best way to comprehend drag would be to drive on the highway in your car and do a few experiments. "Rusty Wallace hits 228 mph in Talladega trial." Racing NASCAR vehicles is a complex task that involves endurance and strength as well as an amazing understanding of how air moves around a racers car. It's definitely worth a look. The front car displaces the air up and over their car, and your car behind keeps the air flowing over the top. It can also be disastrous, so it is a trade-off for the drivers, but if you want to win, you must learn how to do it properly. In return, you give them a nudge or two to help them gain speed, be careful, though; too much of a bump can cause them to lose control and off into the wall they will go, taking out everyone in their path. 3 interesting facts on how NASCAR telemetry works, A Beginners Guide to NASCAR: 6 Highlights of What NASCAR Is Like.

Sixteen drivers advance to 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. This is referred to as negative lift in aerodynamic-speak and racers typically seek to increase this effect. The Clubs take turns selecting players in reverse order of their won-lost records at the close of the previous regular season. At superspeedways like Alabama's Talladega and Florida's Daytona International, where speed is limited by a restrictor plate rule, long lines of drafting cars take advantage of the car in front to allow greater speeds and better fuel efficiency. (Jan. 15, 2009) http://www.stockcarracing.com/featurestories/scrp_0411_restrictor_plate_races_car_destruction/index.html, Hickey, Hannah. University of Washington News and Information. Hill said as the trailing car comes closer to the lead car the air stream under the car, the downforce, is disrupted. Side drafting can only be used with two cars beside each other. Dr. Jerre Hill said he was skeptical about the process, and that the math and physics didn't quite mesh with the reality. Daytona 500 has three stages: What are stages in NASCAR?

Drafting strategy involves more than simply knowing where to place your car on the track, and it often has less to do with aerodynamics and more to do with driver's knowledge of the competition's mind. Reddit - Dive into anything Tandem Drafting made a return when NASCAR removed the restrictor plate and replaced them with Tapered Spacers, and with the flat noses and bumpers of the modern Gen 6 cars, drivers could more easily tandem and gain speed, much like the early 2010s.
