In 2011, two-car tandem drafting was used for the extent of the Aaron's 499, with many drivers drafting their own teammates (e.g., Jimmie Johnson and Dale Earnhardt Jr. drafted together, as did Jeff Gordon and Mark Martin). Boone, Jerry F. "Restrictor Plate Racing - Alternatives to Mayhem." He said the drag created by the boxy truck designs, as well as less horsepower than Cup Series vehicles, put drafting at the top of the strategy list. Double-file racing. Conducted 11/26/2008.

[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. At speed, downforce can add the equivalent of 1,650 to 1,750 pounds (748 to 794 kilograms) of downforce to the tires. It is believed, but not yet conclusively proven, that thoroughbred racing horses draft each other, especially in longer races.[1]. What is the theory behind NASCAR drafting? Because of the sharp turns and lack of long straightaways, drafting is not possible on short tracks or road courses. Plates were first used in the 1970s to even the playing field between larger and smaller engines, as well as a safety measure as the tracks became larger and the cars became more powerful. The initial plan called for the design to be featured in 26 of the 36 races on the 2008 NASCAR schedule and then bumped up to permanent use in the 2009 racing season. This technique is common among hypermilers. Sometimes cars draft in a pack with several cars trailing each other closely. Aerodynamics plays a critical role in racing.

These drivers have the best chance to win the Daytona 500. The same draft that pulls them along can also rob them of the air they need to cool their superheated engines. Studies show that birds in a V formation place themselves roughly at the optimum distance predicted by simple aerodynamic theory.[21]. The flying debris injured more than 30 fans. This increase makes having a drafting partner at superspeedways critical. By staying close to the lead car the trailing car interrupts that low-pressure system and cuts down on its effects. Good design can stick a race car to the track better and allow it to move faster through the air. The best way to do this is to draft the car in front of you or beside you. The birds flying behind will receive lift force from these up-wash vortices. Retired NASCAR driver Brett Bodine said drafting was one of a number of factors and strategies employed by a driver during any given race. It is not something that you can watch on a video screen and become a master at. Lemasters, Ron Jr. (January 2001) "One Wild Wind". Neergaard, Fred. For more racing action, visit F1 Chronicle. "The Kid Wins a Wild One", "Air Force lab tests out 'aircraft surfing' technique to save fuel", "USAF touts flying technique for fuel savings", "Drag Reduction from Formation Flight. Both cars involved in the drafting process mutually benefit from it. Cars must line up closely together in order for drafting to work effectively; this depends on your car's size, weight, and configuration as well as your driving habits.

In either example, whoever has the #1 has the first selection in the NASCAR draft. Director of Communications for New Hampshire Motor Speedway. The side drafting technique is only beneficial for one car as it negatively affects the other car.The rear car pulls up to the side of the front car while keeping the nose of the car close to the front cars back wheel.This pushes the oncoming air onto the front cars spoiler, causing it to lose speed and slow down. This sucks the car downward toward the track surface, allowing it better handling on the turns and a more stable ride. Bodine said the days of practice leading up to a race allow each driver to get to know the other cars.

Johns spun out and crashed and Junior Johnson won the race. It also deals with one of the most basic tenets of physics in racing -- the faster a car goes, the more effect air will have on it and work to slow it down. 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. 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.

When drafting, trailing drivers have very little reaction time to respond in emergencies. Although drafting presents a lot of overtaking opportunities, it also takes a lot of concentration from the trailing driver. The result is a speed increase for both drivers. The tactic failed and Gordon went on for the victory. This was the beginning of the technique of drafting. A wing is designed so airflow creates a low-pressure system over the top of the wing and a relative high-pressure system underneath. The technique is used to attempt a pass. At superspeedways, downforce is purposely reduced since the track layout requires higher speeds on the straightaways. As a result, the lead car is hit with the most air resistance and the drag on the trailing car is significantly reduced., Most types of drafting are allowed in NASCAR.

On smaller tracks with fewer straightaways a car is tuned to have even more downforce to keep it stuck to the pavement and handle the turns better. The lead driver can step on the brakes, come within inches of the following driver, and deprive them of the air needed to cool the engine. The 2023 NASCAR season will officially get started on Sunday, February 19, with the Daytona 500.

Important racing question: Can NASCAR race in the rain? Whatever lane they lead will go just a little faster than the one they just left. 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. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the nose of the following car, actually pulling the second car along with it. Add to that the restrictor plates that limit the amount of air intake to the engine and restricts the speed of the car. There are essentially two kinds of drag -- friction and pressure. Moreover, drivers could acquire track position by picking something contrary to their rivals. This is referred to as negative lift in aerodynamic-speak and racers typically seek to increase this effect. If you're interested in a few drafting success stories, take a look at the next page.

Entering into a draft formation allows for the trailing car to enter the lead cars slipstream. It is based on how much drag you have against your car. Cross-country skiing and running use variations of drafting, too. 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. Each driver has a different price. At the 50th running of the Daytona 500 in 2008, driver Ryan Newman received the "push from heaven" and drafting aid from teammate Kurt Busch (both of Penske Racing) to pass leader Tony Stewart on the backstretch and take the win. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the . That is because the trailing driver gets many opportunities to pass the leading car and can bide his time sitting on the tail for a long time. 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. Racing legend Junior Johnson is acknowledged as the first driver to use drafting as a competitive tactic. If a driver falls out of a drafting pack, there is very little chance of recovery. Earnhardt attempted to "fan" Gordon's tail -- essentially disrupt the downforce off Gordon's car and unstick his wheels by sweeping the nose of his car into Gordon's slipstream. Bodine, Brett. Technically, NASCAR is an independent sport but teams work together for things like information, drafting, and help on the track. Due to the danger, NASCAR has attempted to limit the bracing on bumpers on cars, disallowed bump drafting in turns, introduced "no bump zones" on certain portions of speedways where this practice is prevalent, and penalized drivers who are too rough in bump drafting. He has ridden the draft to 10 combined points wins at restrictor-plate races, including last year's Coke Zero 400.
