In the list of prices that appear in the “totem” of gas stations, one line stands out, that of bioethanol E85, which costs half of gasoline and oil.

With a price per liter of about 0.85 euros, bioethanol or perrethanol is worth the interest of motorists looking for economy. A fuel available at 2,740 service stations to date, often under the Total or Intermarché brand, or about a quarter of French service stations. However, there is no fear of failure, it is always possible to refuel if necessary, as the operation of the engine is flexible. This fuel benefits from profitable taxation because much of it comes from renewable sources rather than minerals, between 65 and 85% depending on the season, a variable percentage to facilitate cold starts in winter, which are more difficult with it.

Today, the bioethanol sector is based on the exploitation of sugar plants (beets and even cane) or fermented cereals such as wheat or corn, distilled in the form of raw alcohol and then dehydrated to make alcohol. pure ethanol that will burn in the engine instead of gasoline. It is the same process used in these factories to produce pure alcohol for medical use or to make strong alcoholic beverages. France leads Europe in agricultural alcohol production, mainly in the north, accounting for 1% of agricultural land for a sector employing more than 9,000 people. A second generation of bioethanol emerges, more virtuous, using, for example, the marcs left after extinction in wine-growing areas. However, the term bioethanol is a bit misleading, as this production today does not come from organic farming.

The E85 ecological balance is very positive, which explains its advantageous taxation, the free gray card in many Regions and the 40% reduction in CO2 emissions for the calculation of the ecological malus. It offers an overall reduction of 71% in greenhouse gases compared to fossil fuels and emits 50% less CO2, according to ePURE. There is also a 90% reduction in particulate emissions, according to a study by a specialized Swiss school.

However, to drive with the E85 in the tank, you need a suitable car. It is possible to convert most models with a specific unit of engine calculation (approximately 1,000 euros). will need 20,000 kilometers of damping, especially since consumption is increased by about 23% with the E85. Two manufacturers, Jaguar Land Rover and Ford, also offer standard vehicles, with the latter being both a hybrid and a Flexifuel, a unique offer on the market.
