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. A fantasy NASCAR draft functions much like a draft in football. Drag refers to the force acting in opposition to an object in motion. It is amply clear that it takes at least two racing cars to adopt the drafting strategy. 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 slingshot is a classic move -- a crowd-pleaser, the gold standard of drafting strategy. Answer (1 of 3): Drafting reduces aero drag, both on the car following and on the car leading. Drafters also face the danger that, if the vehicle in front stops suddenly, there is little time to react. Hendrick counts drivers Jimmie Johnson, Jeff Gordon, Dale Earnhardt Jr. and Mark Martin among the drivers fielded from their North Carolina headquarters.

Long lines of single-file racing at mid-race. 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. The forces at play around a NASCAR vehicle can be manipulated by a talented and trained driver. Hill, Dr. Jerre. 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.

Good design can stick a race car to the track better and allow it to move faster through the air. The two cars that are drafting are then acting as one car in terms of airflow.Due to this reduced air resistance, the two cars then race at higher speeds than they would be able to achieve if they were not drafting.

As we get ready for another NASCAR Cup Series season, let's head into the lab to talk about one of the fundamental principles of racing: drafting. 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. This position gives both the cars an advantage of additional speed as well fuel efficiency. This becomes difficult for drafting cases, if only because a very large wind tunnel is needed.

Drivers resort to drafting on these tracks to attain greater speed and better fuel efficiency. Race cars reach their highest speeds on these superspeedways, so the aerodynamic forces are highest, and the effects of drafting are strongest. Drafting also reduces fuel consumption throughout the race. For example, hypermilers using this technique can achieve 75 mpg or more (a 10% increase in efficiency of certain hybrid vehicles). The aircraft flew at 25,000 feet with a separation of about 200 feet nose-to-tail. That's where we take a look at the more "sophisticated" side of drafting.

In such drafting, all the cars get the benefit of the draft of the preceding cars. Drafting isn't limited to auto racing, though it is most effective at higher speeds where there's more energy from a moving object displacing air therefore creating a slipstream behind it. The end result is about a 5-mile per hour (8-kilometer per hour) increase in speed for each car in the draft. Computer simulation (computational fluid dynamics or CFD) is increasingly being used to analyse drafting. Personal interview. "[3], On the faster speedways and superspeedways used by NASCAR and ARCA, two or more vehicles can race faster when lined up front-to-rear than a single car can race alone.
