Brazil's Dual Fuel Cars will burn up to 100% Ethanol

Brazil has a long history of building and using cars that run only on Ethanol, usually produced from sugarcane. The new Brazillian 'total flex' cars will be based on that technology, but be able to use any blend of ethanol and gasoline or 100% of either.Dual Fuel Cars Revive Brazil's Alcohol Industry:

There are nearly two million 'flex fuel' cars in the United States, but there the process 'is different because they use a mix with a maximum of 85 percent alcohol,' which obligates adding 15 percent gasoline, noted Joao Alvarez Filho, Volkswagen manager for engines and transmission.

The new Brazilian models can run on just gasoline, or 100 percent alcohol, or any proportion mix of the two, he said in a coversation with Tierramarica. The company prefers to call this innovation 'total flex', to reflect the true range of possibilities.

The Brazilian advantage was to develop the dual fuel-based on cars that run exclusively on alcohol, which the country has produced for more than 25 years, a pioneer in the technology.
