Flex-fuel vehicles (FFVs) are capable of running on blends of up to 85% ethanol, or E85, in addition to regular gasoline. The first commercial flexible-fuel vehicle was the Ford Model T, produced from 1908 to 1927, and FFVs have been available in the Brazilian market since the early 2000s. While FFVs are considered more environmentally friendly and can lead to significant decreases in greenhouse gas emissions, their popularity has been impacted by changes in fuel rules and government incentives, with fewer new models being introduced in recent years.

Flex-fuel cars can run on blends of up to 85% ethanol, or E85
Flex-fuel cars, also known as flexible-fuel vehicles (FFVs), can run on blends of up to 85% ethanol, or E85. This means that they can use a combination of ethanol and gasoline, or regular gasoline alone. The most common flex-fuel blend, E85, contains 85% ethanol and 15% gasoline. Ethanol is a sustainable choice as it is plant-derived, often made from corn or sugarcane.
FFVs have sophisticated fuel systems and engines that can handle various ethanol mixes with ease. They are also unique in that they can run on normal gasoline, E85, or a combination of both, giving drivers the flexibility to choose the most economical or readily available option. For example, when fuel prices are lower for E85 than gasoline, FFV owners can take advantage of this by filling up with E85.
E85 is better for the environment than gasoline. It can reduce harmful emissions by up to 40% compared to regular gas, and cut carbon monoxide output by up to 30%. This contributes to efforts to combat climate change and improve air quality. FFVs also bolster energy independence by reducing reliance on oil from overseas.
Despite the benefits of FFVs, there are some drawbacks to using E85. Firstly, E85 typically leads to a 15%-27% decrease in fuel economy due to ethanol's lower energy content. Secondly, E85 is not widely available. In the US, only 2% of motor fuel stations offered E85 as of 2014, and the majority of gas stations pump E10 or E15 gasoline. This limited infrastructure is a major restriction hampering sales of E85 flex vehicles. Additionally, many North American flex-fuel car owners are not aware they own an E85 flex-fuel vehicle due to a lack of exterior labelling.

E85 is better for the environment than gasoline
Flex-fuel cars, which can run on a blend of gasoline and ethanol, have been available in markets such as the US, Canada, Brazil, and Thailand. However, their popularity has waned over the years, with only a handful of models remaining today. Despite this, E85 fuel, which is a blend containing 83% ethanol, has several environmental advantages over gasoline.
Firstly, E85 has a lower environmental impact due to its production process. Gasoline is derived from petroleum extracted from the earth, while E85 is primarily produced from corn grown domestically in the US. This local production shortens the supply chain, reducing the carbon footprint associated with transportation. In addition, the process of growing corn captures carbon dioxide, offsetting the emissions released when ethanol is burned. As a result, E85 has been found to reduce greenhouse gas emissions by up to 50% compared to gasoline, according to the American Coalition for Ethanol.
Secondly, E85 burns cleaner than gasoline due to its composition. Gasoline often contains various hydrocarbons and additives, some of which are harmful to the environment. In contrast, E85, with its high ethanol content, does not contain these harmful substances. This makes E85 a more environmentally friendly option, even when considering the potential decrease in miles per gallon (MPG) associated with its use.
Furthermore, E85 can provide additional benefits to engines. Its higher compressibility before igniting, or higher anti-knock index, allows pistons to travel further with the same amount of fuel, resulting in increased torque. E85 also acts as a cooling agent, helping to lower the temperature of the combustion chamber. While E85 may not be suitable for older vehicles due to its incompatibility with natural rubber, it has been shown to be effective in newer vehicles, even those with higher mileage.
Overall, E85 is a more environmentally conscious choice than gasoline due to its reduced greenhouse gas emissions, cleaner burning properties, and ability to enhance engine performance while cooling the engine. By choosing E85, individuals can actively contribute to the reduction of their carbon footprint and play a part in mitigating climate change.

The number of flex-fuel vehicles has decreased since 2015
Flex-fuel vehicles (FFVs) are cars that can run on alternative fuels, such as an ethanol-gasoline blend, in addition to regular gasoline. FFVs have been around for over 25 years, with the Ford Model T, introduced in 1908, being the first flex-fuel vehicle. FFVs are flexible in the kind of fuel they can consume and can run on regular gasoline and E85 (or flex-fuel). E85 is a blend of gasoline and 51% to 83% anhydrous ethanol.
In 2015, there were 85 FFV models available for sale in the United States, which declined to just 17 in 2022 and 9 in 2023. This significant drop can be attributed to various factors, including the lack of financial incentives for automakers, the limited infrastructure available to sell E85 to the public, and the rise of electric and hybrid vehicles.
The number of flex-fuel vehicles sold and registered in the United States has also decreased since 2015. In 2014, almost half of the new vehicles produced by Chrysler, Ford, and General Motors were flex-fuel, and by 2015, roughly a quarter of all new vehicles sold were capable of using up to E85. However, as of 2022, only Ford, Chevrolet, and General Motors were selling flex-fuel vehicles in America, with 13 models available for sale.
While the number of flex-fuel vehicles has decreased in the United States since 2015, the market for FFVs is still significant. In 2022, there were around 27 million flex-fuel vehicles in the United States, second only to Brazil, which had 34 million. Additionally, the EIA predicts that by 2035, FFVs will account for 19.20% of total vehicles in America, indicating a potential future increase in demand for FFVs.

E85 is very uncommon, with only 2% of US gas stations offering it
Flex-fuel vehicles refer to cars that can use fuels other than gasoline, specifically an ethanol-gasoline blend containing between 51% and 83% ethanol. E85 is a type of flex-fuel that is commercially available. However, E85 is very uncommon, with only 2% of US gas stations offering it. This limited availability is due to several factors, including the placement of E85 pumps, advertising, and the requirements and penalties outlined in gasoline distribution contracts.
Historically, the availability of E85 has been concentrated in the Midwest, benefiting from the region's ethanol fuel production. In 2007, the majority of E85 stations were located in five Midwest states: Minnesota, Illinois, Indiana, Iowa, and Wisconsin. While these states continue to add new E85 locations, other states like California, New York, Colorado, Georgia, and Texas have also experienced rapid growth in E85 availability. As a result, the share of nationwide E85 stations in the Midwest fell from 54% in 2007 to 36% in 2013. Despite this growth, the number of E85 fueling stations in the US only increased by 7% from 2011 to 2013, reaching 2,625 stations. This represents a small fraction of the nation's approximately 156,000 retail motor fuel outlets.
The placement of E85 pumps within gas stations can create challenges for customers. In some cases, E85 pumps may be located outside the main station area, making it less convenient for customers to access. Additionally, advertising practices can impact the visibility of E85. Some stations may not advertise E85 on their street signs or graphics, making it harder for customers to identify that it is available.
Gasoline distribution contracts in the US can also impose requirements that make offering E85 difficult or expensive. These contracts may include provisions such as restrictions on selling E85 under the gas station canopy, specific labeling requirements, minimum sales volumes, and exclusivity provisions. Non-compliance with these contracts can result in severe penalties, including the termination of the agreement and the loss of fuel supplies for retailers.
Despite the low availability of E85, there have been flex-fuel vehicles in the US market. As of 2008, there were an estimated 7 million flex-fuel vehicles capable of running on E85 in the United States. However, a GM study found that around 70% of their flex-fuel vehicle owners were unaware they could use E85, and less than 10% actually used it.

Flex-fuel vehicles are common in the Midwest, where corn is a major crop
Flex-fuel vehicles, or flexible-fuel vehicles (FFVs), are vehicles that can run on multiple types of fuel. The most common type of FFV is the ethanol flex-fuel vehicle, which can run on a mixture of unleaded gasoline and ethanol. FFVs have an internal combustion engine and are capable of operating on gasoline and any blend of gasoline and ethanol up to 83% (or 85% in some sources).
The United States has the second-largest fleet of FFVs in the world, with 27 million registered by the end of 2021. FFVs are particularly common in the Midwest, where corn is a major crop and is the primary feedstock for ethanol fuel production. Regional retail E85 prices vary across the US, with more favourable prices in the Midwest region, where most corn is grown and ethanol is produced.
The US government has been using FFVs for many years, and since 2008, almost any type of automobile and light-duty vehicle has been available on the market with the flex-fuel option. However, the actual use of ethanol fuel is limited due to the lack of E85 refuelling infrastructure and because many North American flex-fuel car owners are not aware they own an E85 flex-fuel vehicle.
FFVs have been promoted by senators who represent corn-producing states, as well as groups such as corn-growing associations. In the past, manufacturers received financial incentives from the government to produce FFVs. For every FFV sold, the manufacturer would get a credit toward the company's Corporate Average Fuel Economy (CAFE) requirements, allowing them to sell less fuel-efficient but more profitable SUVs without receiving a federal penalty. However, this incentive has changed since the Obama administration, and fewer manufacturers get their vehicles certified to sell as FFVs.
