Answer:
Brazilians abandoned ethanol powered automobiles after the mid-1980s due to three primary economic factors. Firstly, the cost of ethanol production became increasingly expensive, leading to higher prices for ethanol fuel. Secondly, the price of gasoline in Brazil decreased, making gasoline a cheaper and more viable alternative fuel option. Finally, Brazil's economy faced a major recession in the 1980s, causing financial strain for many Brazilians, which made them opt for cheaper gasoline cars rather than ethanol-powered cars.
Many Brazilians have recently returned to ethanol-powered cars due to changing economic factors. Oil prices have risen, making gasoline more expensive, while ethanol prices have decreased as Brazil's ethanol industry has become more efficient. Additionally, ethanol-powered cars have become more economical, and the government has put in place financial incentives for the use of ethanol as an alternative fuel source. These factors have made ethanol-powered cars more appealing and cost-effective to many Brazilians.
