DES MOINES, IA - Gov. Tom Vilsack will trade in his gas guzzling sports utility vehicle for a more fuel efficient hybrid vehicle, his spokesman said. Vilsack spokesman Matt Paul said the governor plans to get rid of his 2005 GMC Yukon, which gets 13 miles per gallon, according to Consumer Reports, for a new flexible fuel SUV, which runs on E85, a gas-ethanol blend. E85 is cheaper than the 10-percent ethanol blend and regular unleaded gas sold at most stations. The fuel is only sold at about 20 stations statewide
