High percentage ethanol mixtures are used in some racing engine applications as the very high octane rating of ethanol is compatible with very high compression ratios. The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat. Ethanol is commonly made from biomass such as corn or sugarcane.
Today the mandatory blend is allowed to vary nationwide between 18% and 27.5% ethanol and it is used by all regular gasoline vehicles and flexible-fuel vehicles. The Brazilian car manufacturing industry developed flexible-fuel vehicles that can run on any proportion of gasoline and ethanol. [16]
Straight hydrous ethanol as an automotive fuel has been widely used in Brazil since the late 1970s for neat ethanol vehicles [96] [143] and more recently for flexible-fuel vehicles. [ 144 ] [ 145 ] The ethanol fuel used in Brazil is distilled close to the azeotrope mixture of 95.63% ethanol and 4.37% water (by weight) which is approximately 3.5 ...
Today most biofuels are not currently cost-effective without significant subsidies. "America's ethanol program is a product of government subsidies. There are more than 200 different kinds, as well as a 54 cents-a-gallon tariff on imported ethanol. This prices Brazilian ethanol out of an otherwise competitive market.

The Renewable Industries Canada (RICanada) is a Canadian non-profit organization created in 1984. In 2016, it changed its name from Canadian Renewable Fuels Association (CRFA). The change reinforced the 32 year-old non-profit association's mission to promote the use of value-added products made from renewable resources. [ 1 ]
The Government of Canada collects about $5 billion per year in excise taxes on gasoline, diesel, and aviation fuel [21] as well as approximately $1.6 billion per year from GST revenues on gasoline and diesel (net of input tax credits). The Canada Revenue Agency, a part of the government, collects these taxes.
Flexible-fuel vehicles (FFVs) are based on dual-fuel systems that supply both fuels into the combustion chamber at the same time in various calibrated proportions. The most common fuels used by FFVs today are unleaded gasoline and ethanol fuel. Ethanol FFVs can run on pure gasoline, pure ethanol (E100) or any combination of both.
