Ethanol fuel itself is extracted from plants such as corn or sugarcane, and elegant in to an alcohol. This ethanol is fitting to be used as a biofuel in cars and other vehicles. Most hybrid vehicle engines that use ethanol can moreover use gasoline, and are moreover called "flex-fuel" engines. The ethanol is injected in to the engine in the same way as a non-hybrid vehicle engine. Though ethanol gives somewhat reduction miles per gallon than gasoline, it doesn't emanate as ample air wickedness when it is burned.
The similarities between ethanol "flex-fuel" engines and typical engines make ethanol cars cheaper than many substitute or hybrid vehicles, since they are built in ample the same way as a periodic engine. Ethanol is obviously cheaper in a few cases than gasoline, and thus a hybrid that runs on ethanol may be reduction costly to run than a gasoline formed vehicle.
Most typical automobiles can even run on a 10% combination of ethanol in gasoline. Many gas stations around the world offer ethanol as an substitute to gasoline, and in a few countries cars are compulsory to run on ethanol.
