However, an incident with his arch-rival Paul Tracy that knocked him out on the final lap of the following race in Denver, and a subsequent win by Allmendinger narrowed the gap between the two. Bourdais's win in Montreal and Allmendinger's DNF had widened his points lead to 62 points with three races left, and Bourdais clinched the championship at the next race in Surfers Paradise despite a weak performance in that race. Bourdais became the first Champ Car driver to win three consecutive titles since Ted Horn achieved the hat trick in 1948.
