2009 Sports Car Challenge of St. Petersburg

The 2009 Acura Sports Car Challenge of St. Petersburg was the second round of the 2009 American Le Mans Series season.

The Acura ARX-02a earned its first overall victory under the Patrón Highcroft Racing team after early leader de Ferran Motorsports suffered mechanical issues.

In qualifying solely for the GT2 category, due to the lack of GT1 class competitors for this event, Jaime Melo in the Risi Competizione Ferrari led the pack before a red flag stopped the session due to an incident involving eventual fifth place qualifier Patrick Long in the Flying Lizard Motorsports Porsche.

Acura also led the LMP2 category as the Lowe's Fernández Racing car was piloted by Luis Díaz to third overall, beating the closest Dyson Lola-Mazda by three tenths of a second.
