Starting in 2009, the World Touring Car Championship will move entirely to bio-derived ethanol to fuel its racing vehicles. In 2008, ethanol-motivated racing machines will compete alongside both gasoline and diesel cars before the entire field makes the switch the following year. The FIA is backing the move and aiding in research of fuel types. It'll be interesting to see how the ethanol cars compete against the diesel and petrol vehicles in the thick of the action; we actually wish that the diversity of fuels in the series would remain, as a way to spur development across the board.
