Flex Fuel plays an interesting dual role on the modern automotive landscape. On the one hand, it is lauded as a viable alternative to the traditional engine designs that have long ruled the roost, one that provides the potential to reduce the environmental impact of American motorists and lower the dependence on foreign oil imports.

Either way, Flex Fuel cars have been on the market for close to a decade, and show no signs of leaving the scene any time soon.
