How does the fuel consumption of an ethanol car compare with that of a traditional petrol car?
With petrol operation, the fuel consumption is exactly the same as for a traditional petrol car. With ethanol operation, the fuel consumption per km is higher because ethanol contains less energy than petrol. E85’s energy content is about 70% that of petrol, and bioethanol’s lower retail price compensates for the increased fuel consumption of about 20-35%.
