This is pretty cool:

U.S. Sen. Dick Lugar today joined Sens. Tom Harkin (D-IA) and Barack Obama (D-IL) in introducing the Fuel Security and Consumer Choice Act. This bill would require all U.S. marketed vehicles to be manufactured as Flexible Fuel Vehicles (FFVs) within ten years. FFVs can use both regular gasoline and E-85 renewable fuel (motor fuel with 85 percent ethanol content). This capability would ensure access to an important alternative to foreign petroleum in the future as the nation’s renewable fuels industry continues to expand rapidly.

The bill would require 10 percent of vehicles sold in the U.S. be FFVs within 18 months of passage. The requirement would increase by 10 percent for each subsequent model year resulting in all new vehicles being FFVs within ten years.
