In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.
