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. Tandem Drafting made a return when NASCAR removed the restrictor plate and replaced them with Tapered Spacers, and with the flat noses and bumpers of the modern Gen 6 cars, drivers could more easily tandem and gain speed, much like the early 2010s. The trailing driver has to find the exact spot behind the leading car that gives his car the least resistance and maintains it. Most motor sport aerodynamic analysis is performed using wind tunnel testing. As this happens the nose of the lead car begins to raise a little adding an upforce to the equation. But one year ago, it was Ferrari that got off to a strong start here at . You may have heard an announcer talk about a car being in or out of the draft or refer to a technique like a bump draft or a side draft. 02: .

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. Aerodynamics plays a critical role in racing. Since tandem drafting has been banned, NASCAR has created new technology in the engines, which makes it difficult for the drivers to tandem draft without the engine overheating. Traditional restrictor plates drop the overall power of the cars by about 300 horsepower [source: Boone]. Basically, for any racer, the faster you go, the more you can employ drafting. This enables the trailing driver to increase the speed of his car by up to 5 miles per hour (8 kilometers per hour).

Sometimes cars draft in a pack with several cars trailing each other closely. 02:51. Lemasters, Ron Jr. (January 2001) "One Wild Wind". Having laid the foundation for our new knowledge-engorged racing brains, drafting can thus be understood as the aerodynamic technique where one car closely aligns its nose inches away from the lead car's bumper. Add to that the restrictor plates that limit the amount of air intake to the engine and restricts the speed of the car. Director of Cost Research for NASCAR's Research and Development Center. Untold Stories: NASCAR's first Black driver, Elias Bowie. In order to begin drafting, two drivers that are close to each other on the track need to cooperate. However, tandem drafting was banned by NASCAR in 2014 after a 2013 Daytona race in which the tactic was used led to a massive crash in which driver Kyler Larsons car went airborne, and its debris caused dozens of injuries to spectators. 3.

Cutting through the air and redirecting it to suit the purpose produces a turbulent force behind the car. Answer (1 of 7): Cars do make bumper-to-bumper physical contact to push each other in NASCAR. Because of the sharp turns and lack of long straightaways, drafting is not possible on short tracks or road courses. [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. There, you'll find several articles focused on NASCAR and NASCAR-related topics. And there is always a risk involved with cars racing at 220 miles per hour (362 kph) and close to each other.
