The hotly contested Champ Car World series concludes the years competition today as nineteen drivers will determine the outcome of what has been the most thrilling season in recent memory.
Bourdais cruised around Mexico City's temporary road-circuit with a top time of 1:30.565 (110.745 mph) on Sunday morning, some five seconds slower than his pole winning run, however most drivers and teams go for race setup during the final practice.
The battle within the Newman/Haas camp, where the equally prepared duo competed fiercely with Forsythe Racings' Paul Tracy and Patrick Carpentier, has now emerged as the series focus over the past few events.
Sophomore driver Bourdais has played the rabbit for most of the year, while Junqueira, affectionately referred to by fellow drivers as "Junky", has chased the Frenchman relentlessly. Just when Junqueira has been positioned to take control of the championship, Bourdais will pull out a win with cat-like poise.
Several championship spots will be solidified during the event today. Carpentier and Tracy have there own inner struggle, both men going for third best this year with four points separating the two.
Carpentier wound up with second best during the warm-up, Junqueira ended the session in third.
