Flexible Fuel Technology: Flex Engines

Author's Note

FFVs and E85 are getting more and more common, so the pros and cons of the ethanol business model are being played out in the real world for everyone to witness. Corn growers love FFVs because they create greater demand (and higher prices) for their product. And some environmental lobbyists see E85 as a stepping stone to cleaner-burning fuel sources. But whether ethanol can make a serious, long-term dent in our dependence on foreign oil remains to be seen.
