2006 NASCAR Nextel Cup Series

The 2006 NASCAR Nextel Cup Series was the 58th season of professional Stock car racing in the United States and the 35th modern-era NASCAR Cup series season. It was started at Daytona International Speedway on Sunday, February 12 with the Budweiser Shootout and ended on Monday, November 20, with the Ford 400 at Homestead-Miami Speedway. The Chase for the Nextel Cup began with the Sylvania 300 on Sunday, September 17, at New Hampshire International Speedway. This was the last full-time season with the Gen 4 car.

Tony Stewart, driver of the No. 20 Chevrolet for Joe Gibbs Racing, was the defending series champion, but lost out in defending his championship this year, having finished outside of the top 10 in the points standings after the Chevy Rock and Roll 400. He did, however, claim a $1 million (US) bonus as the best finisher outside the Chase for the Nextel Cup drivers, winning three of the ten Chase races. By the end of the season Chevrolet had captured 23 victories, and 270 points to win the NASCAR Manufacturers' Championship over Ford.^[1]

The 2006 season was the first for Ford's all-new Fusion, which replaced the Taurus both in NASCAR and in showrooms. Also, a new version of the Chevrolet Monte Carlo, called the Monte Carlo Super Sport (SS for short) debuted on the circuit. Additionally, 2006 was the first Cup Series season since 1979 without Rusty Wallace and 1974 without Ricky Rudd, although Rudd made one appearance in relief and would return for one final year in 2007 before retiring. It was also the last season before Toyota joins the NASCAR Cup Series as a manufacturer.
