That pressure differential, low on top and high on the bottom, creates lift that allows the plane to soar through the air. As you can imagine, finding the perfect adjustment can prove difficult. At superspeedways, downforce is purposely reduced since the track layout requires higher speeds on the straightaways. As a result, passing is often the result of cooperation between two or more drivers or is achieved by sucking air off the side of the car being passed, a technique called side-drafting.[7]. Johns spun out and crashed and Junior Johnson won the race. Bump drafting can turn risky if the rear car bumps the front car too harshly. Explained.

Team inventory of cars is now also being much more regulated by NASCAR in the interest of controlling costs and increasing parity. 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. But the trailing cars play a role as well. This utilizes the lead car's slipstream to effectively mitigate drag because the air directly behind the lead car's bumper is subsequently going to have . At speed, downforce can add the equivalent of 1,650 to 1,750 pounds (748 to 794 kilograms) of downforce to the tires. The second car can slip into that disturbed air stream and reap the benefits -- that is, if the driver is talented.

Hendrick counts drivers Jimmie Johnson, Jeff Gordon, Dale Earnhardt Jr. and Mark Martin among the drivers fielded from their North Carolina headquarters. That same reduction also benefits the lead car as the presence of the trailing car reduces the pressure drag off the back of the lead car. Slipstream dynamics can be used by drivers pulling close behind large trucks on the highway. Romberg, Kurt. The drag is how much resistance your hand has to the air particles that hit your palm as you switch it in different directions. Any sudden move by one driver can lead to crashes and pile-ups when pack drafting is attempted. [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.
