Neergaard, Fred. Swimmers -- both open water and pool competitors -- will often swim close to another athlete to take advantage of the slight vacuum and less-dense water created in the wake, and on the sides, of the lead swimmer. That way they can conserve fuel and their engines for a final charge towards the finish line. 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. At speed, downforce can add the equivalent of 1,650 to 1,750 pounds (748 to 794 kilograms) of downforce to the tires. Bodine said the days of practice leading up to a race allow each driver to get to know the other cars. The Los Angeles Memorial Coliseum in Los Angeles, California will host the 2023 Busch Light Clash at .

That's where we take a look at the more "sophisticated" side of drafting. [4], In recent years, as aerodynamics have become increasingly critical to the performance of stock cars on "intermediate" oval tracks (between 1.33 and 2 mi) and superspeedways not requiring restrictor plates (such as the Indianapolis Motor Speedway), the effect of turbulent, or "dirty" air when following closely behind another car has become much more akin to that described above in open-wheel racing (a situation described in NASCAR circles as aero push), and is often cited as a main reason for a decrease in the amount of overtakes.

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. 4-time Indianapolis 500 winner Rick Mears was quoted by motorsport.com writer David Malsher in 2015 as saying "The fact is, grip created by aerodynamic downforce is our enemy At the moment, the downforce is so great that it masks the handling and hurts the racing. His average draft position was 122, meaning he was a 13th-round pick in 10-team leagues. There are essentially two kinds of drag -- friction and pressure. 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. NASCAR has become one of racing's leaders in tweaking drag and constantly strives to reduce this effect on its cars. Drafting: The practice of two or more cars, while racing, to run nose-to-tail, almost touching. Anyone who approaches the race in that manner will either crash or burn out the cars engine much before the end of the race. [8] It begins as normal drafting, but the following car pulls up behind the lead car and bumps into the rear of it, pushing the lead car ahead, to maintain momentum. 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. A fantasy NASCAR draft functions much like a draft in football. Hendrick counts drivers Jimmie Johnson, Jeff Gordon, Dale Earnhardt Jr. and Mark Martin among the drivers fielded from their North Carolina headquarters. The stage winner gets 10 championship points and a playoff point, second gets nine points and no playoff points, third gets eight, and so on. It is a dangerous and exhilarating sport. 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. How To Pick Drivers - Drafting Your Team.

When a vehicle is racing it encounters resistance from the air. You have to draft an entire team of X drivers while staying under your salary cap of $50,000. At superspeedways, downforce is purposely reduced since the track layout requires higher speeds on the straightaways. 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. Answers to the 8 Most Interesting NASCAR Questions. Think of tossing a ball through the air. Below are a few examples of NASCAR wins where drafting attack and defense were critical to success. This could lead to crashes and pile-ups on shorter tracks. It is based on how much drag you have against your car. The front car displaces the air up and over their car, and your car behind keeps the air flowing over the top. It also helps the leading car increase its speed by reducing the drag on the car because the trailing car gives a smooth flow to the air coming off the leading car. The basic physics of the draft -- from the two-car draft to draft lines -- can be used by teams to accelerate their drivers or stall the competition by depriving them of reduced pressure drag.

Given that inescapable law, NASCAR teams design, redesign, refine, tweak and nudge their cars to control what happens when several thousand pounds of vehicle rip through the air at speeds often approaching 200 mph (322 kilometers per hour). Successively, each cyclist leads the group. The order of selection is without regard to League. 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.

Hypermiling.com. Drafting in NASCAR is the art of tailing a leading car closely enough to avoid the turbulence in the wake of the leading car. The trailing car drafts the lead car, uses the pressure reduction to ease its movement through the air, waits for the right curve, mashes the gas and uses the extra power to slingshot ahead for the race victory.

This is in large part due to drafting where an understanding of the physics involved allow drivers to help reduce drag and gain a few more miles per hour (kilometers per hour) in the process. Racing cars just reverse the strategy by reducing the pressure underneath the car as compared to that above the car. A wing is designed so airflow creates a low-pressure system over the top of the wing and a relative high-pressure system underneath.
