2006 Stock Car Brasil season
The 2006 Stock Car Brasil season (known for commercial reasons as the 2006 Copa Nextel Stock Car season) was the 28th edition of the Stock Car Brasil Championship. The season began at the Interlagos Circuit on April 9 and concluded at the same circuit on December 10. The season was won by Cacá Bueno; winning his first of five Stock Car Brasil championships.
The season was notable for the arrival of Volkswagen as one of the series' manufacturers, alongside Mitsubishi and Chevrolet. The series also introduced a new point system dubbed the Super Final, similar to NASCAR's Chase for the Cup. At the conclusion of the eighth round in Brasília, the top ten placed drivers would be locked in and would compete for the championship across the remaining four rounds. The system would remain in place until the conclusion of the 2011 season.
