Terminology

As ethanol FFVs became commercially available during the late 1990s, the common use of the term "flexible-fuel vehicle" became synonymous with ethanol FFVs. See definition in Glossary and Abbreviations In the United States flex-fuel vehicles are also known as "E85 vehicles". In Brazil, the FFVs are popularly known as "total flex" or simply "flex" cars. In Europe, FFVs are also known as "flexifuel" vehicles. Automakers, particularly in Brazil and the European market, use badging in their FFV models with the some variant of the word "flex", such as

In the US, only since 2008 FFV models feature a yellow gas cap with the label "E85/Gasoline" written on the top of the cap to differentiate E85s from gasoline only models. Flexible-fuel vehicles (FFVs) are based on dual-fuel systems that supply both fuels into the combustion chamber at the same time in various calibrated proportions. The most common fuels used by FFVs today are unleaded gasoline and ethanol fuel. Ethanol FFVs can run on pure gasoline, pure ethanol (E100) or any combination of both.

were producing popular models of flex cars and light trucks. ''Production up to December 2010'' The adoption of ethanol flex fuel vehicles was so successful, that production of flex cars went from almost 40 thousand in 2003 to 1.7 million in 2007. This rapid adoption of the flex technology was facilitated by the fuel distribution infrastructure already in place, as around 27,000 filling stations countrywide were available by 1997 with at least one ethanol pump, a heritage of the ''Pró-Álcool'' program. In the United States, initial support to develop alternative fuels by the government was also a response to the first oil crisis, and some time later, as a goal to improve air quality. Also, liquid fuels were preferred over gaseous fuels not only because they have a better volumetric energy density but also because they were the most compatible fuels with existing distribution systems and engines, thus avoiding a big departure from the existing technologies and taking advantage of the vehicle and the refueling infrastructure. California led the search of sustainable alternatives with interest focused in methanol. Ford Motor Company and other automakers responded to California's request for vehicles that run on methanol. In 1981, Ford delivered 40 dedicated methanol fuel (M100)

production in Brazil was transferable to methanol. The success of this small experimental fleet of M100s led California to request more of these vehicles, mainly for government fleets. In 1983, Ford built 582 M100 vehicles; 501 went to California, and the remaining to New Zealand, Sweden, Norway, United Kingdom, and Canada. As an answer to the lack of refueling infrastructure, Ford began development of a flexible-fuel vehicle in 1982, and between 1985 and 1992, 705 experimental FFVs were built and delivered to California and Canada, including the 1.6L Ford Escort, the 3.0L

, and the 5.0L LTD Crown Victoria. These vehicles could operate on either gasoline or methanol with only one fuel system. Legislation was passed to encourage the US auto industry to begin production, which started in 1993 for the M85 FFVs at Ford. In 1996, a new FFV Ford Taurus was developed, with models fully capable of running on either methanol or ethanol blended with gasoline. This ethanol version of the Taurus became the first commercial production of an E85 FFV. The momentum of the FFV production programs at the American car companies continued, although by the end of the 1990s, the emphasis shifted to the FFV E85 version, as it is today. Ethanol was preferred over methanol because there is a large support from the farming community, and thanks to the government's incentive programs and corn-based ethanol subsidies available at the time. Sweden also tested both the M85 and the E85 flexifuel vehicles, but due to agriculture policy, in the end emphasis was given to the ethanol flexifuel vehicles. Support for ethanol also comes from the fact that it is a biomass fuel, which addresses climate change concerns and

was introduced with E85 compatible engines, and Volvo launched the V70 with a 2.5-litre turbocharged Flexifuel engine. All flexible-fuel vehicles in Sweden use an E75 winter blend instead of E85 to avoid engine starting problems during cold weather. This blend was introduced since the winter 2006–07 and E75 is used from November until March. For temperature below E85 flex vehicles require an engine block heater. The use of this device is also recommended for gasoline vehicles when temperatures drop below . Another option when extreme cold weather is expected is to add more pure gasoline in the tank, thus reducing the ethanol content below the E75 winter blend, or simply not to use E85 during extreme low temperature spells. Sweden has achieved the largest E85 flexible-fuel vehicle fleet in Europe, with a sharp growth from 717 vehicles in 2001 to 243,136 through December 2014.

''See sections or chapters on Brazil (Chp 1), the US (3.3), Europe (Chp 4), and Sweden (4.11)'' In order to achieve these goals several government incentives were implemented. Ethanol, as the other biofuels, was exempted of both, the CO2 and energy taxes until 2009, resulting in a 30% price reduction at the pump of E85 fuel over gasoline. Furthermore, other demand side incentives for flexifuel vehicle owners include a bonus to buyers of FFVs, exemption from the

, up to 20% discount on auto insurance, free parking spaces in most of the largest cities, owner annual registration taxes, and a 20% tax reduction for flexifuel company cars. Also, a part of the program, the Swedish Government ruled that 25% of their vehicle purchases (excluding police, fire and ambulance vehicles) must be alternative fuel vehicles. By the first months of 2008, this package of incentives resulted in sales of flexible-fuel cars representing 25% of new car sales. On the supply side, since 2005 the gasoline fuelling stations selling more than 3 million liters of fuel a year are required to sell at least one type of biofuel, resulting in more than 1,200 gas stations selling E85 by August 2008. Despite all the sharp growth of E85 flexifuel cars, by 2007 they represented just two percent of the four million Swedish vehicles. In addition, this law also mandated all new filling stations to offer alternative fuels, and stations with an annual volume of more than one million liters are required to have an alternative fuel pump by December 2009. Therefore, the number of E85 pumps is expected to reach by 2009 nearly 60% of Sweden's 4,000 filling stations. The Swedish-made Koenigsegg Jesko 300, the low

estimated that in 2011 only 862,837 flex-fuel fleet-operated vehicles were regularly fueled with E85. See Table 6.1 pp. 6–3. As a result, from all the ethanol fuel consumed in the country in 2009, only 1% was E85 consumed by flex-fuel vehicles. ''See Table 2.4'' The E85 blend is used in gasoline engines modified to accept such higher concentrations of ethanol, and the fuel injection is regulated through a dedicated sensor, which automatically detects the amount of ethanol in the fuel, allowing to adjust both fuel injection and spark timing accordingly to the actual blend available in the vehicle's tank. Because ethanol contains close to 34% less energy per unit volume than gasoline, E85 FFVs have a lower mileage per gallon than gasoline. Based on EPA tests for all 2006 E85 models, the average fuel economy for E85 vehicles was 25.56% lower than unleaded gasoline. The American E85 flex-fuel vehicle was developed to run on any mixture of unleaded gasoline and ethanol, anywhere from 0% to 85% ethanol by volume. Both fuels are mixed in the same tank, and E85 is sold already blended. In order to reduce ethanol evaporative emissions and to avoid problems starting the engine during cold weather, the maximum blend of ethanol was set to 85%. There is also a seasonal reduction of the ethanol content to E70 (called winter E85 blend) in very cold regions, where temperatures fall below during the winter. In Wyoming for example, E70 is sold as E85 from October to May. E85 flex-fuel vehicles are becoming increasingly common in the

Barriers to widespread adoption

A 2005 survey found that 68% of American flex-fuel car owners were not aware they owned an E85 flex. This was because the exteriors of flex and non-flex vehicles look exactly the same; there is no sale price difference between them; the lack of consumers' awareness about E85s; and also the initial decision of American automakers of not putting any kind of exterior labeling, so buyers could be unaware they are purchasing an E85 vehicle. Since 2008, all new FFV models in the US feature a bright yellow gas cap to remind drivers of the E85 capabilities and proper flex-fuel badging. Some critics have argued that American automakers have been producing E85 flex models motivated by a loophole in the Corporate Average Fuel Economy (CAFE) requirements, that allows for a fuel economy credit for every flex-fuel vehicle sold, whether or not in practice these vehicles are fueled with E85. This loophole might allow the car industry to meet the CAFE targets in fuel economy just by spending between and that it cost to turn a conventional vehicle into a flex-fuel, without investing in new technology to improve fuel economy, and saving them the potential fines for not achieving that standard in a given model year. The CAFE standards proposed in 2011 for the period 2017–2025 will allow flexible-fuel vehicles to receive extra credit but only when the carmakers present data proving how much E85 such vehicles have actually consumed. A major restriction hampering sales of E85 flex vehicles, or fueling with E85, is the limited infrastructure available to sell E85 to the public with only 2% of the motor fuel stations offering E85 by March 2014. , there were only 3,218 fueling stations selling E85 to the public in the entire U.S., '', there were 3,218 stations Selling E85 across 2013 cities in the U.S.'' while about 156,000 retail motor fuel outlets do not offer any ethanol blend. In addition, there has been a great concentration of E85 stations in the

flexible-fuel cars. The executive decree applies to all gasoline-powered vehicles with engines smaller than 2.0 liters manufactured, imported, and commercialized in the country beginning in 2012, mandating that 60% of such vehicles must have flex-fuel engines capable of running with gasoline or E85, or any blend of both. By 2014 the mandatory quota is 80% and it will reach 100 percent by 2016. All vehicles with engines bigger than 2.0 liters must be E85 capable starting in 2013. The decree also mandates that by 2011 all gasoline stations must provide infrastructure to guarantee availability of E85 throughout the country. The mandatory introduction of E85 flex-fuels has caused controversy among carmakers, car dealers, gasoline station owners, and even some ethanol producers complained the industry is not ready to supply enough ethanol for the new E85 fleet.


India

Union Minister for Road Transport and Highways Nitin Gadkari has emphasised the adoption of alternative fuels which will be import substitutes, cost-effective, pollution-free, indigenous, and discourage the use of Petrol or diesel. During an event held on 20 October 2021, while addressing the media and journalists he has said that the government will ask all vehicle manufacturers to make flex-fuel engines under the Euro VI emission norms in the next six-eight months. Flex-fuel, or flexible fuel, is an alternative fuel made of a combination of gasoline and methanol or ethanol. Mr. Gadkari has predicted that in the next 15 years, Indian automobile industry will be worth Rs 15 lakh crore and the Government is planning to submit an affidavit in the Hon'ble Supreme Court of India to allow manufacturing of flex-fuel engines under the Euro IV emission norms but for now he said that the Indian Government will ask all vehicle manufacturers to make flex-fuel engines (that can run on more than one fuel) under the Euro VI emission norms in the next 6–8 months.

. In 2008 the government announced priority for E85, expecting these flex-fuel vehicles to become widely available in Thailand in 2009, three years ahead of schedule. The incentives include cuts in excise tax rates for E85-compatible cars and reduction of corporate taxes for ethanol producers to make sure E85 fuel supply will be met. This new plan however, brought confusion and protests by the automakers which sign-up for the "eco-cars", as competition with the E85 flex-fuel cars will negatively affect their ongoing plans and investments, and their production lines will have to be upgraded at a high cost for them to produce flex-fuel cars. They also complained that flex-fuel vehicles popular in a few countries around the world, limiting their export potential as compared with other engine technologies.
