The Champ Car World Series concludes an intriguing season in Mexico City, as four-time Series champion Sebastien Bourdais wraps up his Champ Car career in what is certain to be an emotional season finale.

The Gran Premio Tecate presented by Banamex at the Autodromo Hermanos Rodriguez also will feature two popular Mexican drivers looking to stir the local fanbase, while Justin Wilson and Robert Doornbos do battle for second place in the standings and unofficial designation of pre-season 'favourite' to capture next year's Vanderbilt Cup.

While the moves of Mario Dominguez, at Pacific Coast Motorsport, and David Martinez, at Forsythe, will be closely monitored in Mexico, other eyes will turn to the battle for second place between Wilson and Doornbos.

The competition between the two at the 2.774-mile road course promises to be fierce as both drivers gained some momentum at the last race. RuSPORT's Wilson, who spent most of the season sitting in fourth place, moved ahead of Minardi Team USA's Doornbos in the standings thanks to his win in Assen in September - in front of Doornbos' home crowd - building on the momentum of five straight top five finishes and increasing his lead with a podium finish in Australia.

“The Autodromo is a track I really enjoy and I hope we can continue where we left off last year," said Wilson, who overcame a wrist injury to lead until the final lap, "Mexico City has always been a successful event for us as a team, so we're looking forward to going out and getting pole position and will be trying hard to win the race. Finishing second in the championship is really important to the whole team and everyone at RuSPORT is determined to go out on top.”

The Briton's recent success, and his past performances in Mexico City - which number a win, a second and two poles - place him as favourite to claim the title of runner-up, but to do so he will have to see off 'the Flying Dutchman'. Doornbos started the season with podiums in six of nine races, including wins at Mont-Tremblant and San Jose, but a couple of difficult races in Europe put him out of contention for the championship title. However, a strong run at Surfers Paradise has since put him back in the fight for 'second-best', and the run from 14th to fourth helped him clinch the Roshfrans Rookie of the Year Award, as well as increasing his lead in the BBS Hard Charger standings - given to the driver who gains the most positions from his qualifying position at each race - to eleven points.

“It's a shame that the Champ Car season is coming to an end, but time flies when you're having fun!" Doornbos admitted, "I think it's great that Mexico is hosting the final race and, even though the championship has already been decided in favour of Sebastian, I would like to announce a very hard battle in who will become the vice-champion. I know that I'm one of only a few drivers who has never seen the circuit, but that has been the case almost every weekend this season. I trust my team and engineers' experience and, with my motivation being as high as at the start of the season, I'm sure we can do a good job - and hopefully finish where we started.”

Wilson and Doornbos won't have things all their own way, however, as the entire field will hope to go out on a high. While Will Power can still take third place in the standings from Doornbos, the Australian is caught up in a fierce fight for fourth with five drivers still able to reach him. Fortunately for Power, he has received clearance from Champ Car medical officials to race in Mexico City after sustaining two hairline fractures to his left wrist in Australia and, armed with a special carbon-fibre brace and extra track time to adjust to it prior to Friday morning practice, the Team Australia driver look first to defend his championship position.

“Mexico City is a track I really enjoy - this will be my third time back and, last year, I got my first podium in Champ Car there," Power revealed, "After the last couple of races, we are definitely due for a bit of good luck and I would be disappointed not to have a strong finish to the season. We found some really good things when we tested the Aussie Vineyards car at Sebring that I think will work for this track, so I expect to be strong in the first session and look to end the season on a high.”
