Now, see how the sanctioning body and the participants apply the Nascar rules in the race. With more than 800 horsepower being produced in some races, downforce is maximized to stick the car to the track. "Three cars will run faster than two, and five cars will run faster than three," he said. ELI5: How does drafting work in NASCAR Racing? With the palm facing forward, the wind will try to push it backward. Although drafting presents a lot of overtaking opportunities, it also takes a lot of concentration from the trailing driver. In either example, whoever has the #1 has the first selection in the NASCAR draft. 3 interesting facts on how NASCAR telemetry works, A Beginners Guide to NASCAR: 6 Highlights of What NASCAR Is Like. By tailgating, the same effects of reducing drag will pull a car along in the wake of the truck and add a few miles per gallon as the smaller car's engine works less. Kyle Busch is largely responsible for a different type of bump drafting, which is now referred to as "two-car drafting"[citation needed] and "tandem drafting". Conducted 11/26/2008. 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. Instead, the new design was raced in all 36 races on the 2008 schedule and is currently the only car design NASCAR allows to race. "Rusty Wallace hits 228 mph in Talladega trial." How do NASCAR payouts work? This becomes difficult for drafting cases, if only because a very large wind tunnel is needed. The technique is used to attempt a pass. Successively, each cyclist leads the group. What is NASCAR Choose Rule. 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. How can cars be limited on how fast they can go, but still can pass other cars on the racetrack. 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. "You want to know who you can draft behind, what your car will do in the curves and stretches, and how it will react. [15][16], Vortex surfing is a related phenomenon that is currently being investigated by the US Air Force to save fuel on long-distance flights. It is believed, but not yet conclusively proven, that thoroughbred racing horses draft each other, especially in longer races.[1]. The low-pressure wake behind a group's leading car reduces the aerodynamic resistance on the front of the trailing car allowing the second car to pull closer. Drafting is a technique seen in NASCAR all the time. The best way to do this is to draft the car in front of you or beside you. In a competition pool a swimmer may hug the lane line that separates them from the swimmer they are abaft of thereby taking advantage of the liquid slipstream in the other swimmer's wake. Drafting or slipstreaming is an aerodynamic technique where two vehicles or other moving objects are caused to align in a close group, reducing the overall effect of drag due to exploiting the lead object's slipstream. [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. Other drivers began imitating Johnson's technique, and drafting was born. How NASCAR Pre-race and Post-race Inspection Works. "You'll see a guy at Talladega moving around and you know that whatever line he gets in front of moves faster.". The cars are loud and fast. This drafting, as do other drafting benefits both the cars. Media Relations for International Speedways, Inc. In fact, a drag reduction of about a half-percent is seen as a significant gain in NASCAR. 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. The driver of the front car can lose control of the car. Hendrick counts drivers Jimmie Johnson, Jeff Gordon, Dale Earnhardt Jr. and Mark Martin among the drivers fielded from their North Carolina headquarters. Several races have been won by a savvy lead driver that allowed a trailing car to creep up from behind, stay there just a little too long, and leave the field with a heat-blown engine. If you enjoyed this article, then you may want to take a look at the next page, too. NASCAR is just as much about strategy as it is about speed and driver skill. Director of Communications for New Hampshire Motor Speedway. Explained. Most motor sport aerodynamic analysis is performed using wind tunnel testing. When the stock car behind gets within inches of the bumper of the race car in front, they both gain speed because the drag of the air is reduced for both of them. NASCAR.com. [6], Drafting is most important at NASCAR's restrictor plate tracks, Talladega Superspeedway and Daytona International Speedway, where the plates mean that much less power is available to push the large bodies through the air. First and foremost, you set up a draft order. The more cars that are drafting the more in line, the more cars will benefit from the draft of the preceding cars. Editorial credit: Grindstone Media Group / Shutterstock.com Through the purse split, the winner, on average, takes home $47,500 a race while the loser makes close to $8,500.

Drivers have to be very alert at all times to avoid any mishaps. While the lead car blocks the resistance to the trailing car, the trailing car limits the turbulence that comes off the back of the lead car. Editorial credit: Grindstone Media Group / Shutterstock.com Low pressure causes the car to tug forward, reducing drag and speeding up the vehicle. Drivers agree that the other forms of drafting are better and that they feel safer when employing them. Let's start with the basics. By staying close to the lead car the trailing car interrupts that low-pressure system and cuts down on its effects. In 2004, NASCAR driver Rusty Wallace tested a car at Talladega without a restrictor plate and reached a reported top speed of 228 miles per hour (367 kilometers per hour) on the backstretch and had a one-lap average speed of 221 mph.

This is the difference between a driver's starting position, and where he finishes in 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. 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. This physical law is what allows planes to fly. 51 views. Pearson was reportedly worried about a slingshot maneuver from Petty and at the last minute allowed Petty to surge ahead. The thought behind this is that when a car backs out, and then goes forward, it has used twice as much fuel for the same distance.

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. Normal drafting is drafting by a car driver by staying as close to the rear of the leading car as possible to avoid the turbulent flow from the leading car. The trick to drafting is to figure out the person in front of you and use their car to push the air away. The draft is when downforce and drag, as well as a few other factors, come together on the track. This technique is often used during races to help cars move up through the field and gain . 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.

Conducted 12/1/2008. [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. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the .

In such cases, the driver has to conserve fuel and his engine if he wants to finish the race. Or they may try to stay away from a bad pusher, like Denny. Flocks of geese and some other birds fly in a V formation because the wingtip vortices generated by the front bird will create up-wash circulations. University of Washington News and Information. Drag is the downside of downforce. And underneath the hood of every Aug. 9, 2007. Studies show that birds in a V formation place themselves roughly at the optimum distance predicted by simple aerodynamic theory.[21]. Only experienced drivers attempt this type of drafting.

Drafting is only employed when drivers have almost reached the limit of their speed and are striving for more. You must try different things while on the track to get the maximum effects from the procedure. But since we're not all a bunch of Einsteins, before we get into drafting, it's important to first understand the concept of drag. Teams, sometimes official but often an informal collaboration, use the power of drafting to rocket members past the competition, vie for the best track real estate and even steal the race lead at a moment's notice. The adjustments become a bit of a balancing game: Less downforce means greater straightaway speed, but less grip in the turns, and more downforce means improved grip in the turns, but slower straightaway speeds. In NASCAR, drafting refers to a technique in which one car follows closely behind another car in order to reduce the amount of drag that the lead car experiences, allowing both cars to travel faster than they would be able to on their own.
