Grand-Am dropped the Autodromo Hermanos Rodriguez circuit from the schedule, making the April 25 round at Virginia International Raceway the first race to follow the Rolex 24–scheduled for Jan. 24-25–meaning there is a three-month gap between the first two rounds of 2009.
The Mexico City race's future has been uncertain since NASCAR's Nationwide Series announced last year that it would drop its Mexico race, which the Grand-Am race supported on the bill. Grand-Am released a 2009 schedule in early October with Mexico City listed as a standalone event on the schedule but with a tentative date.
Nationwide and Grand-Am both suffered declining crowds ever since they debuted at the track in 2004. The Nationwide race drew an estimated 94,000 fans the first year, while just 57,000 attended in 2008.
NASCAR's decision to drop the race was also fueled by higher costs for team logistics, which also hit Grand-Am teams. AutoWeek
