The article says farmers have been using a 10 percent ethanol blend in their standard gasoline-powered vehicles for years. Now the E85-capable trucks and cars are pretty easily available, they're snapping those up as well. Many farmers are also investing in ethanol production plants.
A few other bits of interest from the article: E85 gets about 17 percent less mileage than standard gasoline and most of the 600+ gas stations around the country that offer E85 are in the Midwest. The article says nothing about how farmland is being turned into subdivisions and how this may affect ethanol's future.
