Ethanol is one of the alternative fuels (renewable) environmentally friendly gas-producing lower carbon emissions compared with gasoline or the like (up to 85% lower).
Basically Ethanol made from corn or other crops, and to date there has been no vehicles (vehicles) designed specifically to be able to use 100% Ethanol.
Use of Ethanol on vehicles typically use two types namely Ethanol Ethanol 10 (E10) which is a mixture of 10% Ethanol and 90% gasoline and can be used in almost all the latest vehicles (please check this issue to the car manufacturer's manual or on vehiclethere).
Ethanol 85 (E85) which is a mixture of 85% Ethanol and 15% gasoline fuel. Vehicles that can use E85 is the type of vehicle that already has a certified Flex-Fuel Vehicles (FFV) are issued by car manufacturers.
If you're curious whether your car can use E85, you can check it here.
Some other facts that we got, among others:
Ethanol is less powerful or 20% lower than the fuel that we can use as a premium, pertamax and others. But this is more due to existing engine designs due to the tests carried out by FORD, Ethanol can deliver even more power about 5%.
Usage of Ethanol (E85) more extravagant about 10-25%.
Ethanol (E85) can only be used on cars (vehicles) which already has a certified Flex-fuel Vehicle (FFV) but in a trial against a car that does not have certification FFV, it turns out the car (production over the 90's ketas) can be run as far as 160 000miles more without problems even there are some parts of the machine that looks better after using E85. You can see it here.
Vehicles that already have certification FFV was not more expensive than existing vehicles in general (using gasoline).
Ethanol prices are cheaper but not as much as imagined that about 15% cheaper than the price of gasoline but the use of ethanol is clearly more advantageous because it is more environmentally friendly and alternative fuel that can be renewed one (renewable). And also most likely the price will go down if Ethanol Ethanol is more and more users.
