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.
