2007 American Le Mans Series

It was a series for Le Mans Prototypes (LMP) and Grand Touring (GT) race cars divided into 4 classes: LMP1, LMP2, GT1, and GT2. It began March 17, 2007, and ended October 20, 2007 after 12 races.

Schedule
Following the ten race schedule of 2006, a twelve race schedule was announced for 2007. While the Portland International Raceway was not part of the new schedule, three new temporary street circuits were added. The Streets of St. Petersburg and the Long Beach Street Circuit were added after the 12 Hours of Sebring, while the new Belle Isle circuit was added before Petit Le Mans.

Ethanol
Announced on February 8, 2007, the American Le Mans Series signed an agreement with the Ethanol Promotion and Information Council (EPIC) to run E10 ethanol-enriched fuel in all gasoline-powered entries. The fuel was 10% ethanol and 90% gasoline. EPIC also sponsored Rahal Letterman Racing's Porsche entry as part of the deal. This was similar to Rahal Letterman's deal in the Indy Racing League. From 2007 season onwards, VP Racing Fuels replaced Sunoco as official gasoline supplier for American Le Mans Series.
