teams are already preparing to introduce
drive systems to cars beginning in 2009 and that could soon be followed by a change in fuels. Since the mid-nineties teams have been required to use fuels that were roughly comparable to pump gasoline with a maximum octane rating of 102 RON (about 97 octane for U.S. pump measurements). Formula may soon follow the path of IndyCars and the American
Series and migrate to
, specifically ethanol. According to retired two-time champion Emerson Fittipaldi, Formula 1 management boss Bernie Eccelstone met last year with ethanol suppliers in Brazil. Brazilian Fittipaldi has a sugar cane plantation in his home country and is currently building an ethanol refinery to produce fuel.
All cars in the IndyCar series run on E100 ethanol. In the ALMS several teams including the GT1
C6Rs are now running cellulosic E85. The
R10s run on GTL
fuel while the rest of the field is fueled by E10.
