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. 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 racing was much the same. At smaller tracks, like Bristol Motor Speedway in Tennessee where drivers turn 16-second laps, the constant curve of the track means less opportunity to draft. "If you fall out of that line, if you have to go to the pits for a problem, you're probably going to get lapped," Bodine said. This is called downforce which is most desirable especially on short tracks that have many turns. "Computers expose the physics of NASCAR." Double-file racing. Senior Lecturer in Mechanical Engineering at the University of North Carolina at Charlotte. Nike worked with the aerodynamics expert Robby Ketchell at the University of New Hampshire to experiment with and select a formation of pacemakers that would best minimize drag on the professionals it sponsored in the project it termed Breaking2. June 10, 2004. How does drafting work? Both tracks offer banked curves and long straightaways where a driver can push a car to its upper limits. This technique is often used during races to help cars move up through the field and gain . 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. This enables both of the cars to go faster. [13] Traveling 10 feet (3.0m) behind the truck produced a 39% gain in efficiency. Only experienced drivers attempt this type of drafting. Drafting is a game of small numbers and risky strategy playing out in a larger drama. Teams try their best to limit the drag on the car but it cannot be eliminated. At speed, downforce can add the equivalent of 1,650 to 1,750 pounds (748 to 794 kilograms) of downforce to the tires. Drafting also occurs in competitive longboarding. Explained. "When you see that, you have to start planning your moves, take advantage of what's being offered.". How Does Side Drafting And Slingshotting Work In Racing? And there is always a risk involved with cars racing at 220 miles per hour (362 kph) and close to each other. The resistance is both frontal and frictional. A car with drafting partners both ahead and behind will lose downforce at both ends. We'll get back to playoff points in a minute. There are seven rounds in the NFL Draft; Round 1 is Thursday (April 25), Rounds 2-3 are Friday (April 26) and Rounds 4-7 are Saturday (April 27.) Stock Car Drafting | HowStuffWorks Pulling within a car length of a lead car benefits the trailing car by reducing drag.

Up next, we'll learn how strategy plays a role in the NASCAR draft. That means going directly behind them in their path and then moving a little to the side. Drafting in racing is an aerodynamic technique in which two cars align closely together, reducing the overall drag by making use of the lead car's slipstream. Drivers will often take advantage of this in the last laps by getting close to a lead competitor in exactly the wrong spot and unsticking their tires by manipulating their downforce stream. Personal Interview. Hill said the changes have a serious effect on the car's wake characteristics and therefore on the drafting potential of the car.

Bodine has seen and experienced this phenomenon, firsthand. As the wind whips around the house the pressure outside of the house is lowered, and the pressure inside the house becomes comparatively higher. 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. "You have to know what your car is going to do at any given point in the race," Bodine said. The Selective Service System is the agency that registers men and is responsible for running a draft. It is a trial and error task at first, and takes years to master. What They Do: Drafters use software to convert the designs of engineers and architects into technical drawings.. Work Environment: Although drafters spend much of their time working on computers in an office, some may visit jobsites in order to collaborate with architects and engineers.Most drafters work full time. This helps keep the car keep firmly on in touch with the track as opposed to flying off it. It is a dangerous and exhilarating sport. Both cars involved in the drafting process mutually benefit from it. Drafting is not a strategy to be employed on shorter tracks with many turns and little banking. How Does Drafting Work In NASCAR? Reddit - Dive into anything In common drafting situations, the lead car breaks through the air in front of the line, or pack, and reduces the friction drag for trailing cars.

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.. The best way to comprehend drag would be to drive on the highway in your car and do a few experiments. Along a long straight a car following close behind another uses the slipstream created by the lead car to close the gap between them, hoping to be able to overtake the leader under braking for the next corner, or if they have a straightline speed advantage, to pass on the straight. NASCAR race cars, in some ways, are sensitive machines. It's for this reason that tracks require restrictor plates and other safety measures to limit top speeds. "You'll see a guy at Talladega moving around and you know that whatever line he gets in front of moves faster.". Drafting can be cooperative: several competitors take turns in the lead position (which requires the most effort and energy consumption). There are essentially two kinds of drag -- friction and pressure. That pressure differential, low on top and high on the bottom, creates lift that allows the plane to soar through the air. [5] Like Johnson, other drivers found they picked up speed running closely behind other cars; and as they experimented they found that a line of cars could sustain higher speeds and/or use less gas (resulting in fewer pit-stops) than a single car running by itself.

Any sudden move by one driver can lead to crashes and pile-ups when pack drafting is attempted. Drafting is one of the most important aspects of racing on superspeedways, and it can be beneficial for other tracks. It is important to understand the aerodynamic behaviour of a motor vehicle when drafting, for example if the rear car is too close to the front car, the air supply to its radiator will be reduced and there is a possibility of the engine overheating.

Johns reportedly was in a drafting position with another driver and the lower pressure from the slipstream was so intense it sucked Johns' rear window out of his car. This increase makes having a drafting partner at superspeedways critical. The contests are salary cap based. Dr. Jerre Hill said he was skeptical about the process, and that the math and physics didn't quite mesh with the reality. The hypermiler is a relatively new breed of driver that seek to push the most miles per gallon they can out of a standard vehicle through techniques like highway coasting, stopping their engine instead of idling at lights and never backing out of a parking spot. University of Washington News and Information. Through the purse split, the winner, on average, takes home $47,500 a race while the loser makes close to $8,500.

This, in turn, led to the introduction of NASCAR's Car of Tomorrow -- a race car designed to be competitive on all NASCAR tracks. Drafters also face the danger that, if the vehicle in front stops suddenly, there is little time to react. The draft is when downforce and drag, as well as a few other factors, come together on the track.
