That's bad news for proponents of alternative fuels like methanol, which haven't proved any less polluting than reformulated gasoline in today's flexible fuel vehicles.
Flexible-fuel vehicles capable of running on gasoline or E85 ethanol, a domestic renewable fuel, are available in some regions of the country.
Nevertheless, the study concluded that the increased use of flexible-fuel vehicles and the switch from gasoline to sugarcane ethanol are expected to stabilize GHG emissions from the light vehicle fleet over the next 25 years despite an expected increase in the number of kilometers traveled.
Let me invent such rule making: We have millions of flexible fuel vehicles now, built to run on regular gasoline or E-85, which is 85% ethanol (alcohol) and 15% gasoline.
This study aims to evaluate the influence of different formulations of gasoline on the behavior of a flexible fuel engine, relating the physicochemical properties of fuels with performance, efficiency and gaseous emissions.
They have pledged to make at least half of their fleets "fuel flexible" by 2012, meaning the ability to use both gasoline and renewable fuels.
Only two years ago, G.M. promoted flexible fuel cars that run on E85, a blend of ethanol and gasoline, as the way to wean Americans off gasoline.
Ford, DaimlerChrysler, and GM are among the automobile companies that sell flexible-fuel cars, trucks, and minivans that can use gasoline and ethanol blends ranging from pure gasoline up to 85% ethanol (E85).
"They buy flexible fuel cars and then they fill them up with gasoline".
In March 2003, Volkswagen launched in the Brazilian market the Gol 1.6 Total Flex, the first commercial flexible fuel vehicle capable of running on any blend of gasoline and ethanol.
