This was the Final Season that Fox Sports/FX, TNT, and NBC covered the Busch Series. Starting in 2007, as part of a new TV contract with the television networks of The Walt Disney Company, ESPN2 televised the entire Busch season with select races on ABC.
There has been some controversy of the use of NEXTEL Cup teams with their drivers in Busch Series races, most notably at NEXTEL Cup tracks where there are Busch Series support races. This has been dubbed by Fox Sports announcer Mike Joy as "Busch Whacking", and many underfunded (or one-car) teams have failed to qualify for these races because of this. Out of the 35 races that were run in the 2006 Busch Series season, 33 of those races were won by NEXTEL Cup Series drivers. The only 2 non-NEXTEL Cup Series drivers that won Busch Series races in 2006 were David Gilliland at Kentucky and Paul Menard at Milwaukee. The 2006 season has been notable for those "double duty" drivers even traveling to sites where there are stand-alone races at Nashville Superspeedway, Kentucky Speedway, Autódromo Hermanos Rodriguez and The Milwaukee Mile just to name a few, even on the rare weeks where there are no NEXTEL Cup races. Kentucky was the big upset where one of the underfunded one-car teams took advantage and pulled off the big upset.
In the end, Kevin Harvick, who at the time drove for Richard Childress Racing in the Cup series, won the 2006 championship on October 13, the second of his career having previously won in 2001. After Harvick won the title, talk began about limiting the number of "Busch Whackers" (Cup drivers) in each race or capping the double-dippers appearances for the entire season or even having a "Chase for the NEXTEL Cup" playoff system in place for the 2007 season since Harvick was so dominant during 2006 as NEXTEL Cup drivers won every race but two in the season. Ultimately, no changes were made until 2011, where NASCAR announced that Cup drivers could only run for points in one series. A limit over the number of races Cup drivers could run was not put into effect until over a decade later in 2017. The Busch/Nationwide/Xfinity Series did not have a playoffs ("Chase") until 2016, ten years later.

This race was held on March 25 at Bristol Motor Speedway. Qualifying was snowed out and the field was set by current owner points. As a result, Kevin Harvick started from pole. The race was also halted by snow and drivers, crews, and fans amused themselves by throwing snowballs and building a snowman. The race was restarted after a 90-minute delay and run full-distance.
This race was held on April 8 at Texas Motor Speedway. Denny Hamlin won the pole, the first of his Busch series career.

This race was held June 17 at Kentucky Speedway. Denny Hamlin won the pole. In a stunning upset, David Gilliland became the first winner in the 2006 season that was not on a team with a Nextel Cup driver. Jeff Fuller was involved in a severe crash where, trying to avoid the spinning car of Jason Leffler, Fuller hit the inside wall at full speed, and the car practically imploded on impact. Fuller suffered a broken wrist and thumb.[1] Later in the race on lap 140, a fire alarm went off in the FX broadcasting booth, with lead broadcaster Phil Parsons jokingly stating there was "nothing to be alarmed about".[2]
This race was held June 24 at The Milwaukee Mile. Aric Almirola won the pole in the car normally driven by Denny Hamlin who actually drove the race in the car and started from the back.

Menard's victory was the only one all season by a full-time Busch Series driver who wasn't also full-time in the Cup Series. Only 41 cars started the race, instead of the usual 43.

Declaring for points in one series: Rules change for 2011
This was the fifth-to-last season where Cup Series drivers could run for points in another series. NASCAR implemented this change after Cup drivers were winning the Busch/Nationwide championships over the series regulars for 5 years straight (2006-2010). If the change had been implemented for the 2006 season, Menard would have been the champion. The rest of the top 10 in the standings would have been Johnny Sauter in 2nd, Kenny Wallace (who finished 11th in points), John Andretti (12th), Jason Leffler (13th), Jon Wood (14th), Ashton Lewis (15th), Stacy Compton (16th), Todd Kluever (17th), and Danny O'Quinn Jr. (19th).
Rookies
A. J. Foyt IV – Released midseason from the #38 Great Clips team after team switched from Dodge to Chevrolet (Foyt IV is under contract to Dodge Motorsports and could not break the contract)
Also, John Andretti was officially considered a Busch Series rookie of the year contender for 2006, even though he is a Winston/Nextel Cup veteran.
ROTY favorite Lamar was released early from his ride at KHI while leading the standings. Eventually, the ROTY came down to a fight between NEXTEL Cup veteran John Andretti and former USAR Pro Cup driver Danny O'Quinn Jr. Eventually, O'Quinn Jr., despite being pulled from his ride for two races in favor of David Ragan to prepare him for his full time Cup season in 2007, still managed to hold off Andretti to win the award by only a single point. Another preseason favorite and 2005 NCTS Rookie of the Year, Tood Kluever, struggled in his transition to the Busch Series. Another USAR driver, Mark McFarland, had an up and down year and was replaced by Shane Huffman. Joel Kauffman and Chris Wimmer made bids for ROTY, but were released from their rides. A. J. Foyt IV, in his transition to stock cars, was released due to a Dodge development deal.
