What You'll Learn
Modern flex-fuel vehicles can contain 10-85% ethanol
Modern flex-fuel vehicles are built using advanced technology, such as electronic sensors, that allow the car to adjust its performance based on the fuel blend. These vehicles can run on a blend of gasoline and ethanol, with ethanol content ranging from 10% to 85%. This flexibility in fuel type provides several benefits to consumers and the environment.
Flex-fuel vehicles can use either regular unleaded gasoline or E85, a blend of 85% ethanol and 15% gasoline. E85 is a renewable and domestically produced alternative fuel that offers a more environmentally friendly option compared to traditional gasoline. Ethanol burns cleaner than gasoline, resulting in fewer toxic fumes and reduced greenhouse gas emissions, which helps combat climate change. Additionally, ethanol is produced from sustainable sources such as cane sugar and corn, reducing our reliance on foreign oil.
While flex-fuel technology offers environmental advantages, there are also some considerations to keep in mind. One concern is the gas mileage of flex-fuel vehicles. Some experts argue that these vehicles have similar mileage to their gasoline-only counterparts, while others claim that they have lower gas mileage. This discrepancy may be due to the fact that ethanol contains less energy than gasoline, resulting in reduced efficiency. However, the lower energy content of ethanol is offset by its typically lower price, resulting in a net cost savings for consumers.
Another important consideration is the potential impact of flex-fuel production on crop allocation and prices. As ethanol is produced from crops like corn, dedicating these crops to fuel production may drive up the price of animal feed and make them more susceptible to weather conditions and diseases. Additionally, ethanol's tendency to absorb dirt can potentially corrode and damage engines over time.
Despite these considerations, flex-fuel vehicles offer a viable alternative to traditional gasoline-only cars. With their ability to adjust to different fuel blends and take advantage of the environmental and economic benefits of ethanol, flex-fuel vehicles present a promising option for those seeking a more sustainable and cost-effective mode of transportation.

Ethanol is sustainably produced from sugar and corn
Ethanol is a domestically produced alternative fuel that can be sustainably produced from sugar and corn. In fact, it is the main source of ethanol fuel in the United States. It is also used in other countries, such as Brazil, which is the world's second-largest consumer of fuel ethanol. In the US, nearly all fuel ethanol is produced from corn kernel starch, while in Brazil, ethanol is produced from sugar cane.
Ethanol is produced by ethanol fermentation and distillation. In the US, the most common method is dry milling, where the corn kernel is ground into flour or "mash," mixed with water, and processed at high temperatures to reduce bacteria levels. Enzymes are added to convert the starch into simple sugars, and then yeast is added to ferment the sugars into ethanol and carbon dioxide. The entire process takes 40 to 50 hours, and the ethanol is then dehydrated using a molecular sieve system.
Another method is wet milling, where the corn grain is steeped in dilute sulfurous acid for 24 to 48 hours to separate its components. The slurry then goes through grinders to separate the corn germ, and the remaining fiber, gluten, and starch are segregated. The corn starch and water can then be fermented into ethanol through a similar process as dry milling.
Ethanol is a good alternative to purchasing foreign oil, and it has the added benefit of being domestically produced. It is also more environmentally friendly than gasoline, with lower greenhouse gas emissions and full biodegradability. However, there are some concerns about the sustainability of corn ethanol due to the energy sources of US distilleries, as well as the large amount of arable land required for crops, which can impact grain supply and land use.

Using ethanol reduces tailpipe emissions
Ethanol is a cleaner-burning fuel that can be sustainably produced from crops such as corn and sugar cane. Using ethanol in vehicles has measurable benefits in terms of reducing tailpipe emissions. Firstly, it reduces carbon dioxide (CO2) emissions. The CO2 released when ethanol is burned as fuel is offset by the CO2 absorbed by the crops used to make the ethanol as they grow. A study by the Argonne National Laboratory found that using corn-based ethanol instead of gasoline leads to a 40% reduction in lifecycle greenhouse gas (GHG) emissions on average.
Ethanol also helps to reduce other harmful tailpipe emissions. For example, a blend of gasoline with 10% ethanol (E10) can be replaced with a blend containing 15% ethanol (E15) to significantly reduce the emission of harmful pollutants. These include carbon monoxide, which affects the body's ability to deliver oxygen to organs, and exhaust hydrocarbons, which contribute to ozone formation, irritate the eyes, damage the lungs, and aggravate respiratory issues.
Additionally, ethanol fuels can reduce air toxics like benzene, a known carcinogen that can cause cancer and reproductive issues or birth defects. Fine particulate matter, which can enter the lungs and cause serious health issues, is also reduced. A 2021 study by the Hormel Institute, University of Minnesota, and the Energy Resources Center at the University of Illinois Chicago found that increasing the ethanol content in fuel can significantly reduce the risk of cancer by displacing toxic chemicals found in gasoline.
While some may argue that ethanol can negatively impact a vehicle's performance, modern flex-fuel vehicles are designed with advanced technology, including electronic sensors, that enable them to adjust their operation based on the fuel blend. These vehicles can determine the most efficient proportions of fuel blends and make the necessary adjustments. Therefore, using ethanol in flex-fuel vehicles not only reduces tailpipe emissions but also allows for efficient vehicle operation.

GM has sold over 8.5 million flex-fuel vehicles
Flex-fuel vehicles are becoming increasingly popular, and for good reason. As of 2017, there were over 21 million E85 flex-fuel vehicles in the United States, with GM playing a significant role in this market. In fact, GM has sold over 8.5 million flex-fuel vehicles in North America, making up a large portion of the total flex-fuel vehicles on the road.
GM has shown a strong commitment to alternative fuels and was the first automaker to make the necessary hardware and software changes to support higher ethanol blends in their vehicles starting with the 2012 model year. This means that many GM cars are already equipped with the capability to run on a blend of different liquid fuels, including methanol, ethanol, or gasoline, without any modifications.
However, for those who want to take matters into their own hands, it is possible to hack your car to make it flex-fuel capable. This involves connecting to the car's computer and making changes to the software. By doing so, you can potentially save a significant amount on fuel costs, as flex-fuel vehicles can take advantage of alternative fuels like ethanol, which is more environmentally friendly and can be produced from sustainable sources such as cane sugar and corn.
While GM has made strides in flex-fuel technology, there are still challenges to its widespread adoption. One issue is the lack of E85 refueling infrastructure, which can make it difficult for owners of flex-fuel vehicles to take advantage of the benefits. Additionally, some concerns have been raised about the potential impact of flex-fuel on engine performance and gas mileage, as ethanol contains less energy than gasoline.
Despite these challenges, the trend towards flex-fuel vehicles is likely to continue, with more ethanol refining plants opening up and consumers becoming increasingly aware of the benefits of alternative fuels. As a result, it's worth considering making the switch to flex-fuel, whether through purchasing a GM flex-fuel vehicle or exploring the possibility of hacking your existing car to unlock its flex-fuel potential.

A software upgrade can convert a gasoline car to flex-fuel
A software upgrade can indeed convert a gasoline car to a flex-fuel vehicle. This process involves connecting directly to the car's computer and making changes to the software. This can be done by copying the software code and loading it into a PC database, then performing a translation to make it readable. From there, one can adjust the settings to allow the vehicle to run on different types of fuel.
For example, John Brackett of PUMP demonstrated how to convert a gasoline-powered Chevy Cruze into a flex-fuel vehicle in just a few seconds. He connected to the car's computer and showed that the vehicle could run on a blend of three different liquid fuels: methanol, ethanol, or gasoline, or any combination of these.
To convert a gasoline car to flex-fuel, one will need to make some upgrades to the engine. If your vehicle is fuel-injected and is a 1995 model or newer, you will need an electronic control module that plugs into the fuel injectors and the factory fuel injector electrical connectors. This module adjusts the fuel injection rate based on the oxygen sensor's signal. Additionally, a fuel sensor is required to detect the alcohol/gasoline ratio and determine the necessary fuel flow.
It is important to note that flex-fuel vehicles have some differences in performance compared to gasoline-powered cars. The energy density of alcohol is lower than gasoline, so the fuel economy may be reduced. Ethanol also has less energy than gasoline, so more of it is needed to produce the same energy output. However, modern flex-fuel vehicles are equipped with technology that allows them to detect the fuel blend and make the necessary adjustments to maintain performance.
