Justin Wilson stormed to a victory in Sunday's Gran Premio Telmex/Tecate Presented by Banamex by leading 65 of 70 laps around the Autodromo Hermanos Rodriguez, but leaving it that is like reading the final chapter of a Stephen King novel and thinking you got the plot.

Wilson fought off a number of fierce challenges from teammate A.J. Allmendinger, including a final charge after a lap 65 restart, to score his second victory of the Champ Car World Series. Allmendinger held on to the second spot for his fifth podium finish of the year and Paul Tracy powered back from a pair of incidents that sent him to the back of the pack to take his seventh podium finish of the campaign.

Wilson roared away from Allmendinger at the start while Tracy earned the first of his two trips to the rear of the field, suffering a punctured tyre in turn one while battling for the third spot behind the two RuSPORT machines. Tracy fell back to 19th after getting new Bridgestones and immediately returned to battle, turning laps just as quick as the leaders. Allmendinger stayed within a second of Wilson over the first 20 laps while series champion Sebastien Bourdais clawed his way back from five seconds down to tuck in behind the rear wing of Allmendinger as the first pit windows started to open.

Tracy and Rodolfo Lavin were the first to pit, rolling the dice on lap 19 in hopes that the caution banner would bring the duo back into contention. The gamble paid off just one lap later as Ronnie Bremer had heavy contact in turn 13, bringing out the yellow flag for a lengthy cleanup.

The entire field, save Tracy and Lavin, rolled down pit lane for their first fuel stops, promoting Lavin to the lead as the hometown crowd roared. The pit stops went smoothly for most of the field but, having done her duty for him for 2005, Lady Luck turned her back on Bourdais. The Newman/Haas pilot suffered a miscue in the pits that not only relegated him to the back of the field, but necessitated a second stop to ensure that there was no damage.

Lavin led Tracy and Wilson into the first turn on the lap 27 restart but Lavin's advantage would fail to last through a second bend in the course. Tracy slid around Lavin heading into turn one, but Lavin cut back outside and retook the point for the briefest of seconds before he and Tracy had contact. Tracy recovered from the contact, but the incident opened the door for Wilson to slip past and into the lead. Lavin was not as fortunate as he suffered a punctured tyre that sent him down pit lane for new shoes.

Wilson headed toward turn four with the lead while Tracy tried to maintain his hold on the second spot ahead of Allmendinger. Tracy moved to the far left of the track to keep the young Californian at bay, but would end up going to the back again as Champ Car Race Control determined that Tracy was guilty of blocking in keeping Allmendinger in the third spot. The resulting drive-through penalty dropped Tracy to the 16th position while Wilson and Allmendinger roared away.

The lanky Brit sprinted away from the field after retaking the lead, building a lead of more than six seconds over Allmendinger and knocking Cristiano da Matta more than 14 back. While Wilson ticked off laps at the front of the queue, Tracy and Bourdais ripped through the back of the field on their way to the top 10. Bourdais went hammer-and-tong with Andrew Ranger for the 10th spot as the rookie fought off the series champion for three hard-fought laps before finally relinquishing his position.

Da Matta dropped back to fifth as series runner-up Oriol Servia and Mario Dominguez slipped by for third just prior to the final round of green-flag stops, a move that would seal the end of the day for Bourdais in another ten laps.
