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. The 2010 NASCAR season allowed drivers more freedom; bump drafting was allowed anywhere, including turns. At speed, downforce can add the equivalent of 1,650 to 1,750 pounds (748 to 794 kilograms) of downforce to the tires. The favorites. The trailing car has less front downforce but normal rear downforce. Drivers resort to drafting on these tracks to attain greater speed and better fuel efficiency.

He has to also anticipate and react to the actions of the driver before him quickly if he is to avoid a crash. This position gives both the cars an advantage of additional speed as well fuel efficiency. Milnes, Ken. 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.

[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. In addition to friction drag, there is pressure drag created by the low pressure behind the leading car. Racing legend Junior Johnson is acknowledged as the first driver to use drafting as a competitive tactic. Other types of drafting that are allowed are normal drafting, bump drafting, and side drafting. 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. By staying close to the lead car the trailing car interrupts that low-pressure system and cuts down on its effects. Neergaard, Fred. This cookie is set by GDPR Cookie Consent plugin.

Bump drafting is when a trailing car bumps the leading car lightly and then follows the car closely to take advantage of the draft. You can imagine how dangerous drafting is, which is shown every time a bump draft goes wrong. The side drafting technique is only beneficial for one car as it negatively affects the other car.The rear car pulls up to the side of the front car while keeping the nose of the car close to the front cars back wheel.This pushes the oncoming air onto the front cars spoiler, causing it to lose speed and slow down. Race teams will now be limited to seven cars per car number at a . It takes more than a lead foot and nerves of steel. [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. Remember to draft all of the correct positions, so that you can have a full team roster. Once you have your target get directly behind them and lightly bump into their bumper. Plates were first used in the 1970s to even the playing field between larger and smaller engines, as well as a safety measure as the tracks became larger and the cars became more powerful.

A trailing car (perhaps pushed by a line of drafting cars) uses the lead car's wake to pull up with maximum momentum at the end of a straightaway, enters a turn high, and turns down across the lead car's wake. On Sunday, all the Daytona 500 staples were there: Big wrecks.

After Ryan Newman's scary crash in the 2020 Daytona 500, NASCAR made efforts to change drafting at superspeedways, where less horsepower was used: the removal of aero ducts to eliminate tandem drafting and decrease closing rates, and a smaller throttle body to lower the amount of air into a racecar.

The lead driver can step on the brakes, come within inches of the following driver, and deprive them of the air needed to cool the engine. The same physical forces allowing Johnson to keep up with the competition led to Johns' defeat. It begins when the trailing car gets within inches of the front car's rear .

Drafting uses the air molecules around the car that is created by the force of the forward motion. The lead car, by displacing the air in front of it, creates a vacuum between its rear end and the . Drafters also face the danger that, if the vehicle in front stops suddenly, there is little time to react. Drafting is not a strategy to be employed on shorter tracks with many turns and little banking. That way they can conserve fuel and their engines for a final charge towards the finish line. "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. Side drafting can also work, but this is used more for passing than gaining speed.
