Factories turned out 697,731 neat-ethanol cars and light trucks that year, 72.6% of the total, under a government plan called Pró-Álcool, according to production figures in the history of ethanol fuel in Brazil. Seven years earlier the number had been 4,614. That is a roughly 150-fold jump in seven years. How a sugar country built an alcohol car Brazil launched its National Alcohol Program in 1975, two years after the first oil shock, to replace gasoline with ethanol distilled from sugarcane. Cane was the obvious feedstock: sugar was cheap at the time, the country’s sugar mills had spare distilling capacity, and Brazil had grown cane since 1532. The first phase simply blended ethanol into gasoline. Then, pushed by the second oil crisis, the program went further. In May 1979 the first 16 filling stations started selling hydrous ethanol to a fleet of 2,000 adapted vehicles, and by July Fiat had put the 147 on sale. It was the first modern car sold anywhere built to run on pure ethanol, known as E100. Making an engine drink alcohol took real changes. Carmakers raised compression ratios, adjusted fuel injection, swapped parts that ethanol would corrode, fitted colder spark plugs and added a small gasoline tank to help on cold mornings. Why drivers bought in The state stacked the deck. The national oil company Petrobras guaranteed to buy ethanol, producers got low-interest loans, and pump prices were fixed so hydrous ethanol cost 59% of the gasoline price. By the late 1980s more than four million pure-ethanol cars and light trucks were on the road, about a third of all motor vehicles in the country. The 1989 crunch Then the math flipped. Oil prices fell during the 1980s glut, from an average of $78.20 a barrel in 1981 to $26.80 in 1986, measured in 2004 dollars. World sugar prices jumped late in 1988, mills switched to sugar, and by mid-1989 ethanol ran short. Thousands of cars sat in lines at filling stations or stayed parked at home with empty tanks. Drivers lost faith fast. Neat-ethanol models fell to about 10% of production in 1990, and in 1998 Brazil built just 1,451. Brazil even began importing ethanol from Europe and Africa in 1991 as subsidies were cut back. What survived The pumps did. Around 27,000 filling stations had at least one ethanol pump by 1997, a leftover of Pró-Álcool, and that network made the next idea work. In March 2003 Volkswagen launched the Gol 1.6 Total Flex, which could burn any mix of gasoline and ethanol, so drivers no longer had to bet on one fuel. Flex cars reached 94% of new sales in August 2009, and in February 2008 ethanol overtook gasoline with more than 50% of retail fuel sales, a level last seen at Pró-Álcool’s peak. Timeline 1931: a decree requires 5% ethanol in imported gasoline. 1975: Pró-Álcool launches. July 1979: the Fiat 147 goes on sale as an ethanol-only car. 1986: ethanol-only models hit 72.6% of light-vehicle output. Mid-1989: fuel shortage breaks public trust. March 2003: the first flex-fuel car arrives. For more car history, read how Chevrolet Vega cars rode trains standing on their noses and how Porsche assembled 10,479 Mercedes 500 E sedans. Ordinary gasoline in Brazil has carried ethanol ever since; in March 2015 the required blend rose to 27%.
