Page "Drafting (aerodynamics)" Paragraph 14

Kyle Busch is largely responsible for the current popularity of bump drafting, which is now referred to as ' two-car drafting '.

At a 2007 test session in Talladega, he asked Ryan Newman to push him from behind, and was stunned to realize he was two seconds faster with Newman's help.

At the newly paved Daytona International Speedway in 2011, Busch was the first to realize that the corners were smooth enough to allow a two-car draft for the complete length of the track.

During test sessions on the track, when Busch was pushed by his brother's Penske teammate Brad Keselowski, they ran 15 mph faster than single cars.

Other drivers quickly picked up on Busch's strategy, and the two-car draft dominated the 2011 Daytona 500 and Budweiser Shootout.

This strategy had also been very prominent at Talladega.

In 2011, two-car tandem drafting was used for the extent of the Aaron's 499, with many drivers drafting their own teammates ( e. g., Jimmie Johnson and Dale Earnhardt, Jr. drafted together, as did Jeff Gordon and Mark Martin ).
