In 2006, the American
Series saw a dominating performance in their top LMP1 class from the
R10s. For 2007 they have announced a partnership with the Ethanol Promotion and Information Council (EPIC), to use
blended fuels in their gasoline powered racers. Unlike the IndyCars that started using an ethanol blend last year, and straight E100 for 2007, ALMS cars will be running on E10 (ten percent ethanol/ninety percent gasoline) for 2007. The 2007 ALMS season kicks off on March 17 at
for the Twelve Hour race and includes twelve races. Click the Read link for the full press release.
