Teams try their best to limit the drag on the car but it cannot be eliminated. The hypermiler is a relatively new breed of driver that seek to push the most miles per gallon they can out of a standard vehicle through techniques like highway coasting, stopping their engine instead of idling at lights and never backing out of a parking spot. Wallace described the experience as "insane" [source:]. 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. If worst comes to worst and the race has to stop, the driver in the lead after at least 100 laps or the end of Stage . Bicycle racers and speed skaters most often take advantage of drafting. Drafting also requires two other things to fall into place. What actually happens in drafting? Racing games such as most in the Mario Kart series simulate it by giving the player a speed boost. Anyone who approaches the race in that manner will either crash or burn out the cars engine much before the end of the race.

Additionally, on the same episode, Mythbusters demonstrated that it can be very dangerous for the following car if one of the truck's tires (or their recaps) delaminate, as the chunks of ejected rubber can be large enough to cause serious harm, even death, to a driver following too closely.[14]. No one, on his own, can do the work being shared by the vehicles in the draft train, so long as the draft train can all run together. NASCAR vs IndyCar: What are the 4 main differences? The result is a speed increase for both drivers. How does downforce help a NASCAR race car? Bump drafting can turn risky if the rear car bumps the front car too harshly. By staying close to the lead car the trailing car interrupts that low-pressure system and cuts down on its effects. This drafting, as do other drafting benefits both the cars. You can imagine how dangerous drafting is, which is shown every time a bump draft goes wrong. Thats when you will see the enormous pile-ups that can end the day for the racers involved. Both cars involved in the drafting process mutually benefit from it. 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.

Although drafting presents a lot of overtaking opportunities, it also takes a lot of concentration from the trailing driver. 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. How can cars be limited on how fast they can go, but still can pass other cars on the racetrack. These are super-fast tracks with good banking on the turns where drivers can push their cars to the limit throughout the race. This helps keep the car keep firmly on in touch with the track as opposed to flying off it. The trailing driver can also get close to the leading car to disrupt the flow over the car. "You see two cars side-by-side, you know there's a big hole behind them and if you can get in that you can accelerate faster," Bodine said, adding that, in the truck series, the vehicles punch bigger holes in the air, allowing for even more acceleration in the draft position.
